    The purpose of this study was to determine the presence, frequency, and intensity of pain during speaking in professional voice users and nonvocal professionals and to determine if the presence of pain is significantly related with the profile of the professional voice user. Based on the available literature, significantly more pain symptoms in professional voice users can be hypothesized. Sample survey. To characterize the presence, type, and degree of pain symptoms during speaking, a questionnaire was used. Pain severity was measured by means of a numerical rating scale. Fifty-five (176/320) percent of the nonvocal professionals and 84% (698/832) of the professional voice users mentioned the presence of one or more pain symptoms during speaking. Throat pain was mentioned as the most common pain in both the professional and nonvocal professional voice users. The professional voice users showed significantly more throat, neck, shoulder, headache, ear, and back pain. Moreover, the intensity of throat pain was significantly increased in the professional voice users. This study showed evidence that several types of pain are present with significantly greater frequency in professional voice users. Vocal screening strategies, diagnostic, and treatment protocols should include the assessment of the type and severity of pain. Currently, the voice clinic is working on improving the diagnostic protocol with the objective of defining the combination of tests, which best diagnose voice problems and related complaints and which evaluate progress in vocal characteristics and pain after rehabilitation.

    Common problems among all patients seen by the laryngologist are also common among professional voice users. These include laryngopharyngeal reflux, muscle tension dysphonia, fibrovascular vocal fold lesions (eg, nodules and polyps), cysts, vocal fold scarring, changes in vocal fold mobility, and age-related changes. Microvascular lesions and their associated sequelae of vocal fold hemorrhage and laryngitis due to voice overuse are more common among professional voice users. Much more common among professional voice users is the negative impact that voice problems have on their ability to work, on their overall sense of well-being, and sometimes on their very sense of self. This article reviews the diagnosis and treatment options for these and other problems among professional voice users, describing the relevant roles of medical treatment, voice therapy, and surgery. The common scenario of multiple concomitant entities contributing to a symptom complex is underscored. Emphasis is placed on gaining insight into the "whole" patient so that individualized management plans can be developed. Videos of select diagnoses accompany this content online.

    There are few data demonstrating the specific extent to which surgical intervention for vocal fold nodules (VFN) improves vocal function in professional (PVU) and non-professional voice users (NVU). The objective of this study was to compare and quantify results after phonomicrosurgery for VFN in these patient groups. In a prospective clinical study, surgery was performed via microlaryngoscopy in 37 female patients with chronic VFN manifestations (38±12 yrs, mean±SD). Pre- and postoperative evaluations of treatment efficacy comprised videolaryngostroboscopy, auditory-perceptual voice assessment, voice range profile (VRP), acoustic-aerodynamic analysis, and voice handicap index (VHI-9i). The dysphonia severity index (DSI) was compared with the vocal extent measure (VEM). PVU (n=24) and NVU (n=13) showed comparable laryngeal findings and levels of suffering (VHI-9i 16±7 vs 17±8), but PVU had a better pretherapeutic vocal range (26.8±7.4 vs 17.7±5.1 semitones, p<0.001) and vocal capacity (VEM 106±18 vs 74±29, p<0.01). Three months postoperatively, all patients had straight vocal fold edges, complete glottal closure, and recovered mucosal wave propagation. The mean VHI-9i score decreased by 8±6 points. DSI increased from 4.0±2.4 to 5.5±2.4, and VEM from 95±27 to 108±23 (p<0.001). Both parameters correlated significantly (rs=0.82). The average vocal range increased by 4.1±5.3 semitones, and the mean speaking pitch lowered by 0.5±1.4 semitones. These results confirm that phonomicrosurgery for VFN is a safe therapy for voice improvement in both PVU and NVU who do not respond to voice therapy alone. Top-level artistic capabilities in PVU were restored, but numeric changes of most vocal parameters were considerably larger in NVU.

    Voice is one of the most important instruments for expression and communication in humans. Dysphonia remains very frequent. Generally people in voice-intensive professions, such as teachers, call center employees, singers and actors suffer from these complaints. In recent years methods have been developed which facilitate appropriate diagnosis and therapy, based on the criteria of evidence based medicine, in voice patients appropriate to their degree of disease. The basic protocol of the European Laryngological Society offers a standardized evaluation of multidimensional voice parameters. In our own patient collective there were statistically significant improvements in voice quality, according to a pre/post mean value comparison, in both phonomicrosurgical (n=45) and voice therapy (n=30) patients in relation to RBH, DSI and VHI.

    This pilot study aimed to evaluate the internal consistency, convergent construct validity and criterion validity of Arabic version of the Vocal Tract Discomfort Scale (VTDS), and to investigate the correlation between the scores of the VTDS, the VHI and the acoustic measures of fundamental frequency (F0), shimmer, jitter and signal-to-noise ratio (SNR). A cross-sectional study where 97 participants participated (47 males and 50 females) (mean age 20.5 ± 2.1 years) (31 student singers and 66 other non-professional voice user students). Participants were without self-perceived voice disorders who completed the VTDS-Arab scale and the Voice Handicap Index (VHI-Arab), and recorded a vocal sample of/a:/at a comfortable level. A positive internal consistency that signifies reliability was confirmed by Cronbach's α = .884 and 0.874 for the VTDS-Arab frequency and severity subscales, respectively. A moderate positive correlation was found between the VTDS-Arab (frequency, severity, total) and the VHI-Arab total where values of Pearson's correlation coefficient were r= 0.459, 0.430 and 0.451, respectively. Weak correlations were found between all of the acoustic measures and the scores of the VTDS-Arab and VHI-Arab (total and subscales). The area under curve for the VTDS was AUC= 0.824, 0.804 and 0.817 for the VTDS frequency, VTDS severity and VTDS total, respectively. The VTDS-Arab is a valid and reliable tool in measuring vocal tract sensations and predicting the perception of vocal handicap in student singers and can be used to predict the vocal load among professional voice users.

    Recent advances with regard to occupational voice disorders are highlighted with emphasis on issues warranting consideration when assessing, training, and treating professional voice users. Findings include the many particularities between the various categories of professional voice users, the concept that the environment plays a major role in occupational voice disorders, and that biopsychosocial influences should be analyzed on an individual basis. Assessment via self-evaluation protocols to quantify the impact of these disorders is mandatory as a component of an evaluation and to document treatment outcomes. Discomfort or odynophonia has evolved as a critical symptom in this population. Clinical trials are limited and the complexity of the environment may be a limitation in experiment design. This review reinforced the need for large population studies of professional voice users; new data highlighted important factors specific to each group of voice users. Interventions directed at student teachers are necessities to not only improving the quality of future professionals, but also to avoid the frustration and limitations associated with chronic voice problems. The causative relationship between the work environment and voice disorders has not yet been established. Randomized controlled trials are lacking and must be a focus to enhance treatment paradigms for this population.

    To evaluate the psychological effects of dysphonia in voice professionals compared to non-voice professionals and in both genders. Cross-sectional analysis. Forty-eight 48 voice professionals and 52 non-voice professionals with dysphonia were included in this study. All participants underwent a complete ear, nose, and throat examination and an evaluation for pathologies that might affect vocal quality. Participants were asked to complete the Turkish versions of the Voice Handicap Index-30 (VHI-30), Perceived Stress Scale (PSS), and the Hospital Anxiety and Depression Scale (HADS). HADS scores were evaluated as HADS-A (anxiety) and HADS-D (depression). Dysphonia status was evaluated by grade, roughness, breathiness, asthenia, and strain (GRBAS) scale perceptually. The results were compared statistically. Significant differences between the two groups were evident when the VHI-30 and PSS data were compared (P = .00001 and P = .00001, respectively). However, neither HADS score (HADS-A and HADS-D) differed between groups. An analysis of the scores in terms of sex revealed that females had significantly higher PSS scores (P = .006). The GRBAS scale revealed no difference between groups (P = .819, .931, .803, .655, and .803, respectively). No between-sex differences in the VHI-30 or HADS scores were evident We found that voice professionals and females experienced more stress and were more dissatisfied with their voices. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Full Text Available The reasonability for the usage of computer systems user voice in the authentication process is proved. The scientific task for improving the signal/noise ratio of the user voice signal in the authentication system is considered. The object of study is the process of input and output of the voice signal of authentication system user in computer systems and networks. Methods and means for input and extraction of voice signal against external interference signals are researched. Methods for quality enhancement of user voice signal in voice authentication systems are suggested. As modern computer facilities, including mobile ones, have two-channel audio card, the usage of two microphones is proposed in the voice signal input system of authentication system. Meanwhile, the task of forming a lobe of microphone array in a desired area of voice signal registration (100 Hz to 8 kHz is solved. The usage of directional properties of the proposed microphone array gives the possibility to have the influence of external interference signals two or three times less in the frequency range from 4 to 8 kHz. The possibilities for implementation of space-time processing of the recorded signals using constant and adaptive weighting factors are investigated. The simulation results of the proposed system for input and extraction of signals during digital processing of narrowband signals are presented. The proposed solutions make it possible to improve the value of the signal/noise ratio of the useful signals recorded up to 10, ..., 20 dB under the influence of external interference signals in the frequency range from 4 to 8 kHz. The results may be useful to specialists working in the field of voice recognition and speaker’s discrimination.

    2010-07-01

    This work concerns the collection of 30 voice range profiles (VRPs) of female operatic voice. We address the questions: Is there a need for a singer's protocol in VRP acquisition? Are physiological measurements sufficient or should the measurement of performance capabilities also be included? Can we address the female singing voice in general or is there a case for categorizing voices when studying phonetographic data? Subjects performed a series of structured tasks involving both standard speech voice protocols and additional singing tasks. Singers also completed an extensive questionnaire. Physiological VRPs differ from performance VRPs. Two new VRP metrics, the voice area above a defined level threshold and the dynamic range independent from the fundamental frequency (F(0)), were found to be useful in the analysis of singer VRPs. Task design had no effect on performance VRP outcomes. Voice category differences were mainly attributable to phonation frequency-based information. Results support the clinical importance of addressing the vocal instrument as it is used in performance. Equally important is the elaboration of a protocol suitable for the singing voice. The given context and instructions can be more important than task design for performance VRPs. Yet, for physiological VRP recordings, task design remains critical. Both types of VRPs are suggested for a singer's voice evaluation. Copyright (c) 2010 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    The study was carried out to assess the role that five hearing history variables (chronological age, age at onset of deafness, age of first cochlear implant [CI] activation, duration of CI use, and duration of known deafness) play in the ability of CI users to identify speaker gender. Forty-one juvenile CI users participated in two voice gender identification tasks. In a fixed, single-interval task, subjects listened to a single speech item from one of 20 adult male or 20 adult female speakers and had to identify speaker gender. In an adaptive speech-based voice gender discrimination task with the fundamental frequency difference between the voices as the adaptive parameter, subjects listened to a pair of speech items presented in sequential order, one of which was always spoken by an adult female and the other by an adult male. Subjects had to identify the speech item spoken by the female voice. Correlation and regression analyses between perceptual scores in the two tasks and the hearing history variables were performed. Subjects fell into three performance groups: (1) those who could distinguish voice gender in both tasks, (2) those who could distinguish voice gender in the adaptive but not the fixed task, and (3) those who could not distinguish voice gender in either task. Gender identification performance for single voices in the fixed task was significantly and negatively related to the duration of deafness before cochlear implantation (shorter deafness yielded better performance), whereas performance in the adaptive task was weakly but significantly related to age at first activation of the CI device, with earlier activations yielding better scores. The existence of a group of subjects able to perform adaptive discrimination but unable to identify the gender of singly presented voices demonstrates the potential dissociability of the skills required for these two tasks, suggesting that duration of deafness and age of cochlear implantation could have

    To analyze the phonatory and laryngopharyngeal symptoms reported by call center operators; and quantify the impact of these symptoms on quality of life, and the association between these issues and professional performance, number of monthly calls, and number of missed workdays. Call center operators (n=157) from a billing call center completed the Vocal Signs and Symptoms Questionnaire and the Brazilian version of the Voice Activity and Participation Profile (VAPP). The company provided data regarding professional performance, average number of monthly calls, and number of missed workdays for each employee. The mean number of current symptoms (6.8) was greater in the operators than data for the general population (1.7). On average, 4.2 symptoms were attributed to occupational factors. The average number of symptoms did not correlate with professional performance (P=0.571). However, fewer symptoms correlated with decreased missed workdays and higher mean monthly call figures. The VAPP scores were relatively low, suggesting little impact of voice difficulties on call center operator's quality of life. However, subjects with elevated VAPP scores also had poorer professional performance. The presence of vocal symptoms does not necessarily relate to decreased professional performance. However, an association between higher vocal activity limitation and participation scores and poorer professional performance was observed. Copyright © 2012 The Voice Foundation.

    People with a high level of disability experience great difficulties to perform activities of daily living and resort to their residual motor functions in order to operate assistive devices. The commercially available interfaces used to control assistive manipulators are typically based on joysticks and can be used only by subjects with upper-limb residual mobilities. Many other solutions can be found in the literature, based on the use of multiple sensory systems for detecting the human motion intention and state. Some of them require a high cognitive workload for the user. Some others are more intuitive and easy to use but have not been widely investigated in terms of usability and user acceptance. The objective of this work is to propose an intuitive and robust user interface for assistive robots, not obtrusive for the user and easily adaptable for subjects with different levels of disability. The proposed user interface is based on the combination of M-IMU and EMG for the continuous control of an arm-hand robotic system by means of M-IMUs. The system has been experimentally validated and compared to a standard voice interface. Sixteen healthy subjects volunteered to participate in the study: 8 subjects used the combined M-IMU/EMG robot control, and 8 subjects used the voice control. The arm-hand robotic system made of the KUKA LWR 4+ and the IH2 Azzurra hand was controlled to accomplish the daily living task of drinking. Performance indices and evaluation scales were adopted to assess performance of the two interfaces.

  1. The role of spectral and temporal cues in voice gender discrimination by normal-hearing listeners and cochlear implant users.

    The present study investigated the relative importance of temporal and spectral cues in voice gender discrimination and vowel recognition by normal-hearing subjects listening to an acoustic simulation of cochlear implant speech processing and by cochlear implant users. In the simulation, the number of speech processing channels ranged from 4 to 32, thereby varying the spectral resolution; the cutoff frequencies of the channels' envelope filters ranged from 20 to 320 Hz, thereby manipulating the available temporal cues. For normal-hearing subjects, results showed that both voice gender discrimination and vowel recognition scores improved as the number of spectral channels was increased. When only 4 spectral channels were available, voice gender discrimination significantly improved as the envelope filter cutoff frequency was increased from 20 to 320 Hz. For all spectral conditions, increasing the amount of temporal information had no significant effect on vowel recognition. Both voice gender discrimination and vowel recognition scores were highly variable among implant users. The performance of cochlear implant listeners was similar to that of normal-hearing subjects listening to comparable speech processing (4-8 spectral channels). The results suggest that both spectral and temporal cues contribute to voice gender discrimination and that temporal cues are especially important for cochlear implant users to identify the voice gender when there is reduced spectral resolution.

    Teachers are at risk of developing voice disorders. A clinical battery of vocal function tests should include non-invasive and accurate measurements. The quantitative methods (e.g., voice acoustic analysis) make it possible to objectively evaluate voice efficiency and outcomes of dysphonia treatment. To identify possible signs of vocal fatigue, acoustic waveform perturbations during sustained phonation were measured before and after the vocal-loading test in 51 professionally active female teachers with functional voice disorders, using IRIS software. All the participants were also subjected to laryngological/phoniatric examination involving videostroboscopy combined with self-estimation by voice handicap index (VHI)-based scale. The phoniatric examination revealed glottal insufficiency with bowed vocal folds in 35.2%, soft vocal nodules in 31.4%, and hyperfunctional dysphonia with a tendency towards vestibular phonation in 19.6% of the patients. In the VHI scale, 66% of the female teachers estimated their own voice problems as moderate disability. An acoustic analysis performed after the vocal-loading test showed an increased rate of abnormal frequency perturbation parameters (pitch perturbation quotient (Jitter), relative average perturbation (RAP), and pitch period perturbation quotient (PPQ)) compared to the pre-test outcomes. The same was true of pitch-intensity contour of vowel /a:/, an indication of voice instability during sustained phonation. The recorded impairments of voice acoustic parameters related to vocal loading provide further evidence of dysphonia. The voice acoustic analysis performed before and after the vocal-loading test can significantly contribute to objective voice examinations useful in diagnosis of dysphonia among teachers.

    The purpose of this paper is to describe learning gained from involving service users and carers as researchers in an action research study. The researchers aimed to introduce self-directed support in mental health services--part of the government's personalisation agenda, which requires a move from current social care commissioning, where a person is matched to available services, to one where a person self-assesses, has an agreed support plan and then with appropriate help, purchases his or her own services to lead as independent a life as possible. This development is allied closely with the mental health service recovery approach. Three service users and two carers were recruited to work alongside the lead researcher. Service users were fully involved in the steering group - part of participatory action research project. Data were collected from: debriefing meetings with co-researchers between April and December 2007; a group interview held by the lead researcher; and participants' journal comments and self-reflections. The main areas in which service users and carers found involvement difficult were: overcoming professional language barriers; emotional impact; and power imbalances between themselves and professionals. Findings suggest that considerable improvement is required by mental health professionals and managers if service users and carers are successfully involved in projects. This is a small study within a larger action research project. Findings are not generalisable owing to the small sample; however, findings are supported by the service-user involvement literature. Few studies explore participation effects on service users and carers from their perspective. This research provides insights into what needs to be addressed to improve service user and carer involvement to improve mental health services.

    Full Text Available The basic purpose of 1ibrarianship code is to form and build librarian personality who can make possible the same opportunity to acquiring knowledge for all users, irrespective of their different demands or special needs.When we discuss the importance of building librarian personality the demanding work with users we confront the problem of ethical treatment very often. Ethics advises only general rules which are rarely simple and they are frequently opposite to each other.The process of reacting between the librarian and the user - as with general information needs as with special functional needs - is also dependent on librarian's professional relation which is formed on important elements such as professional qualification,experiences, creativeness and ethics.We are also interested in question where is the border between ethical and non - ethical action in key situations when the 1ibrarian meets functionally handicapped user. Opportunities for non - ethical reaction of professional workers are much more possible if the library's premises and the furniture don't offer suitable conditions for adaptable communication with the handicapped.But on the other side the 1ibrarian has just because of the bad arhitectural conditions better occasion to introduce himself as one of the best ethically formed personalies compared with other professions. With adaptable communication, creative work and with professional relation in offering help to disabled people, the librarian can contribute to more quality service and even more - he/she becomes an example to other professions - also in ethical sense.

    The aim of this study was to assess the application of Voice Handicap Index (VHI) in the diagnosis of occupational voice disorders in teachers as compared with the dysphonic non-teachers population. The subjective assessment of voice by VHI was performed in 105 teachers with dysphonia and 60 dysphonic subjects whose jobs did not involve vocal effort. The control group comprised 65 healthy individuals with normal voice. The results of total VHI score and each of its subscales, functional, emotional and physical, were significantly worse in the study groups (I and II) than in the control group (p teachers and 16% of non-teachers reported severe voice disability. All individuals in the control group assessed their voice problems as minor, their results fell within the range of the lowest level of VHI score. This study confirmed that VHI as a tool for self-assessment of voice can significantly contribute to the diagnosis of occupational and non-occupational dysphonia.

Focus groups were conducted with health care professionals and experienced manual wheelchair users. ICF codes were used to identify focus group themes. The Activities and Participation codes were more frequently used than Structure, Function and Environment codes. Wheelchair skills identified as important for new manual wheelchair users included propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain. Health care professionals and manual wheelchair users identified the need to incorporate the environment (home and community) into the wheelchair training program. Identifying essential components for training the proper propulsion mechanics and wheelchair skills in new manual wheelchair users is an important step in preventing future health and participation restrictions. Implications for Rehabilitation Wheelchair skills are being addressed frequently during rehabilitation at the activity-dependent level. Propulsion techniques, transfers in an out of the wheelchair, providing maintenance to the wheelchair and navigating barriers such as curbs, ramps and rough terrain are important skills to address during wheelchair training. Environment factors (in the home and community) are important to incorporate into wheelchair training to maximize safe and multiple-environmental-setting uses of manual wheelchairs. The ICF has application to understanding manual wheelchair rehabilitation for wheelchair users and therapists for improving

    Health research is frequently conducted in multi-disciplinary teams, with these teams increasingly including service user researchers. Whilst it is common for service user researchers to be involved in data collection--most typically interviewing other service users--it is less common for service user researchers to be involved in data analysis and interpretation. This means that a unique and significant perspective on the data is absent. This study aims to use an empirical report of a study on Cognitive Behavioural Therapy for psychosis (CBTp) to demonstrate the value of multiple coding in enabling service users voices to be heard in team-based qualitative data analysis. The CBTp study employed multiple coding to analyse service users' discussions of CBT for psychosis (CBTp) from the perspectives of a service user researcher, clinical researcher and psychology assistant. Multiple coding was selected to enable multiple perspectives to analyse and interpret data, to understand and explore differences and to build multi-disciplinary consensus. Multiple coding enabled the team to understand where our views were commensurate and incommensurate and to discuss and debate differences. Through the process of multiple coding, we were able to build strong consensus about the data from multiple perspectives, including that of the service user researcher. Multiple coding is an important method for understanding and exploring multiple perspectives on data and building team consensus. This can be contrasted with inter-rater reliability which is only appropriate in limited circumstances. We conclude that multiple coding is an appropriate and important means of hearing service users' voices in qualitative data analysis. © 2012 John Wiley & Sons Ltd.

    The aim of this paper is to compare the prevalence of voice disorders and the risk factors for them in different occupations with a vocal load in Slovenia. A meta-analysis of six different Slovenian studies involving teachers, physicians, salespeople, catholic priests, nurses and speech-and-language therapists (SLTs) was performed. In all six studies, similar questions about the prevalence of voice disorders and the causes for them were included. The comparison of the six studies showed that more than 82% of the 2347 included subjects had voice problems at some time during their career. The teachers were the most affected by voice problems. The prevalent cause of voice problems was the vocal load in teachers and salespeople and respiratory-tract infections in all the other occupational groups. When the occupational groups were compared, it was stated that the teachers had more voice problems and showed less care for their voices than the priests. The physicians had more voice problems and showed better consideration of vocal hygiene rules than the SLTs. The majority of all the included subjects did not receive instructions about voice care during education. In order to decrease the prevalence of voice disorders in vocal professionals, a screening program is recommended before the beginning of their studies. Regular courses on voice care and proper vocal technique should be obligatory for all professional voice users during their career. The inclusion of dysphonia in the list of occupational diseases should be considered in Slovenia as it is in some European countries.

  10. Occupational risk factors and voice disorders.

    From the point of view of occupational health, the field of voice disorders is very poorly developed as compared, for instance, to the prevention and diagnostics of occupational hearing disorders. In fact, voice disorders have not even been recognized in the field of occupational medicine. Hence, it is obviously very rare in most countries that the voice disorder of a professional voice user, e.g. a teacher, a singer or an actor, is accepted as an occupational disease by insurance companies. However, occupational voice problems do not lack significance from the point of view of the patient. We also know from questionnaires and clinical studies that voice complaints are very common. Another example of job-related health problems, which has proved more successful in terms of its occupational health status, is the repetition strain injury of the elbow, i.e. the "tennis elbow". Its textbook definition could be used as such to describe an occupational voice disorder ("dysphonia professional is"). In the present paper the effects of such risk factors as vocal loading itself, background noise and room acoustics and low relative humidity of the air are discussed. Due to individual factors underlying the development of professional voice disorders, recommendations rather than regulations are called for. There are many simple and even relatively low-cost methods available for the prevention of vocal problems as well as for supporting rehabilitation.

    A novel Multiple Access Control (MAC) protocol - User-dependent Perfect-scheduling Multiple Access (UPMA) protocol, which supports joint transmission of voice and data packets,is proposed. By this protocol, the bandwidth can be allocated dynamically to the uplink and downlink traffic with on-demand assignment and the transmission of Mobile Terminals (MTs)can be perfectly scheduled by means of polling. Meanwhile, a unique frame structure is designed to guarantee Quality of Service (QoS) in voice traffic supporting. An effective collision resolution algorithm is also proposed to guarantee rapid channel access for activated MTs. Finally, performance of UPMA protocol is evaluated by simulation and compared with MPRMA protocol.Simulation results show that UPMA protocol has better performance.

    This study aimed (1) to investigate music theory teachers' professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. Using voice dosimetry, 13 music theory teachers were monitored for one workweek. The parameters analyzed were voice sound pressure level (SPL), fundamental frequency (F0), phonation time, vocal loading index (VLI), and noise SPL. Spearman correlation was used to correlate vocal loading parameters (voice SPL, F0, and phonation time) and noise SPL. Each day, the subjects self-assessed their voice using visual analog scales. VLI and self-evaluation data were correlated using Spearman correlation. Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time, and female subjects' F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue, and amount of singing and speaking voice produced. Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders. Correlations between VLI and self-assessments suggest that these teachers are well aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analog scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users. Copyright © 2017 The Voice Foundation.

    The obvious perceptual differences between various singing styles like Western operatic and jazz rely on specific dissimilarities in vocal technique. The present study focuses on differences in vibrato acoustics and in singer's formant as analyzed by a novel software tool, named BioVoice, based on robust high-resolution and adaptive techniques that have proven its validity on synthetic voice signals. A total of 48 professional singers were investigated (29 females; 19 males; 29 Western operatic; and 19 jazz). They were asked to sing "a cappella," but with artistic expression, a well-known musical phrase from Gershwin's Porgy and Bess, in their own style: either operatic or jazz. A specific sustained note was extracted for detailed vibrato analysis. Beside rate (s(-1)) and extent (cents), duration (seconds) and regularity were computed. Two new concepts are introduced: vibrato jitter and vibrato shimmer, by analogy with the traditional jitter and shimmer of voice signals. For the singer's formant, on the same sustained tone, the ratio of the acoustic energy in formants 1-2 to the energy in formants 3, 4, and 5 was automatically computed, providing a quality ratio (QR). Vibrato rates did not differ among groups. Extent was significantly larger in operatic singers, particularly females. Vibrato jitter and vibrato shimmer were significantly smaller in operatic singers. Duration of vibrato was also significantly longer in operatic singers. QR was significantly lower in male operatic singers. Some vibrato characteristics (extent, regularity, and duration) very clearly differentiate the Western operatic singing style from the jazz singing style. The singer's formant is typical of male operatic singers. The new software tool is well suited to provide useful feedback in a pedagogical context. Copyright © 2015 The Voice Foundation.

    2011-08-01

    (1) To investigate whether voice gender discrimination (VGD) could be a useful indicator of the spectral and temporal processing abilities of individual cochlear implant (CI) users; (2) To examine the relationship between VGD and speech recognition with CI when comparable acoustic cues are used for both perception processes. VGD was measured using two talker sets with different inter-gender fundamental frequencies (F(0)), as well as different acoustic CI simulations. Vowel and consonant recognition in quiet and noise were also measured and compared with VGD performance. Eleven postlingually deaf CI users. The results showed that (1) mean VGD performance differed for different stimulus sets, (2) VGD and speech recognition performance varied among individual CI users, and (3) individual VGD performance was significantly correlated with speech recognition performance under certain conditions. VGD measured with selected stimulus sets might be useful for assessing not only pitch-related perception, but also spectral and temporal processing by individual CI users. In addition to improvements in spectral resolution and modulation detection, the improvement in higher modulation frequency discrimination might be particularly important for CI users in noisy environments.

    to investigate acoustic features of phonation and perception of voice handicap in street vendors. Eighty-eight participants (44 street vendors, 44 controls) were recruited. The mean age of the group was 38.9±16.0 years (range: 20-78 years). Scores of the Arabic version of the Voice Handicap Index (VHI-Arab) were used for analysis. Acoustic measures of fundamental frequency (F 0 ), jitter, shimmer, and signal-to-noise ratio (SNR) were also analyzed. Analysis showed a significant difference between street vendors and controls in the total score of the VHI-Arab (p<0.001) as well as scores of all three VHI-Arab subsections: functional (p<0.001), physical (p<0.001), and emotional (p=0.025). Weak correlations were found among all of the VHI scores and acoustic measures (-0.219≤ r≤0.355), except for SNR where a moderate negative correlations were found (r=-0.555; -0.4) between the VHI (physical and total) scores and SNR values. Significant differences also were found in F 0 , jitter, and SNR among specific subgroups of street vendors when stratified by weekly hours worked (p<0.05), and in jitter (p=0.39) when stratified by educational level. Perception of voice handicap and a possible effect on vocal quality in street vendors were noted. The effect of factors, namely work hours and educational level, on voice quality should be further studied. Copyright © 2017. Published by Elsevier Inc.

    2014-09-01

    Like many other countries China is undergoing major health system reforms, with the aim of providing universal health coverage, and addressing problems of low efficiency and inequity. The first phase of the reforms has focused on strengthening primary care and improving health insurance coverage and benefits. The aim of the study was to explore the impacts of these reforms on healthworkers and service-users at township level, which has been the major target of the first phase of the reforms. From January to March 2013 we interviewed eight health officials, 80 township healthworkers and 80 service-users in eight counties in Zhejiang and Yunnan provinces, representing rich and poor provinces respectively. Thematic analysis identified key themes around the impacts of the health reforms. We found that some elements of the reforms may actually be undermining primary care. While the new health insurance system was popular among service-users, it was criticised for contributing to fast-growing medical costs, and for an imbalance of benefits between outpatient and inpatient services. Salary reform has guaranteed healthworkers' income, but greatly reduced their incentives. The essential drug list removed perverse incentives to overprescribe, but led to falls in income for healthworkers, and loss of autonomy for doctors. Serious problems with drug procurement also emerged. The unintended consequences have included a brain drain of experienced healthworkers from township hospitals, and patients have flowed to county hospitals at greater cost. In conclusion, in the short term resources must be found to ensure rural healthworkers feel appropriately remunerated and have more clinical autonomy, measures for containment of the medical costs must be taken, and drug procurement must show increased transparency and accountability. More importantly the study shows that all countries undergoing health reforms should elicit the views of stakeholders, including service-users, to avoid

    Patient satisfaction is an important measure of health care quality. Patients' views have seldom been considered in the construction of measures addressing satisfaction with inpatient facilities in psychiatry. The Views on Inpatient Care - VOICE - is a first service-user generated outcome measure relying solely on their perceptions of acute care, representing a valuable indicator of service users' perceived quality of care. The present study aimed to contribute to the validation of the Portuguese version of VOICE. The questionnaire was translated into Portuguese and applied to a sample of eighty-five female inpatients of a psychiatric institution. Data analysis focused on assessing reliability and exploring the impact of demographic and clinical variables on participants' satisfaction. Internal consistency of the questionnaire was high (α = 0.87). Participants' age and marital status were associated with differences in scores, with older patients and patients who were married or involved in a close relationship presenting higher satisfaction levels. The questionnaire demonstrated good internal consistency and acceptability, as well as construct validity. Further studies should expand the analysis of the psychometric properties of this measure e.g., test-retest reliability. The Portuguese version of VOICE is a promising tool to assess service users' perceptions of inpatient psychiatric care in Portugal.

    2013-03-01

    Health is a basic human right, and drug use represents a severe influence on people's health. This qualitative study aimed to understand how health professionals in a public health-care team working with drug users in a city of the state of São Paulo, Brazil, perceive the human rights of these users and how these rights are being respected in health care. Data were collected through semistructured interviews with 10 health professionals at the service under analysis. A thematic analysis of the interviews reveals the professionals' difficulty to define the concept of human right and contextualize these rights in their work environment. A deeper understanding of the right to health, however, represents an important premise for a more humanized care practice in health services to drug users.

  18. Professionals' views on mental health service users' education: challenges and support.

    Science.gov (United States)

    Nieminen, I; Kaunonen, M

    2017-02-01

    WHAT IS KNOWN ON THE SUBJECT?: Mental health service users (MHSUs) may experience disruptions in their education. However, education has been shown to have a positive influence on their recovery, potentially offering them broader employment opportunities. The literature suggests that providing support for MHSUs in their educational efforts may be beneficial and is wished for by the service users themselves. However, there is a lack of mental health professionals' views on the topic in the setting of a community mental health centre. WHAT DOES THIS PAPER ADD TO THE EXISTING KNOWLEDGE?: In the perception of mental health professionals, the predominance of disease in the life of MHSUs and their marginalization may form barriers to their success in education. Professionals can support MHSUs in their educational efforts by strengthening the MHSUs' internal resources and creating a supportive environment with professional expertise available. A service user-centred education might further help MHSUs to achieve their educational goals. Our findings confirm previous knowledge of a recovery-oriented approach to supporting MHSUs' education. This study explored the topic from the professionals' perspective in the context of community mental health centres, which is a fresh view in the research literature. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The findings suggest which types of support professionals perceive to be required for MHSUs to advance their studies. Knowledge of adequate forms of support can be applied in the mental health nursing practice to develop support measures for service users to advance in their studies. All levels of the community mental health centres should be aware of and adopt a recovery-oriented approach. MHSUs and professionals need to have a shared opinion on the definition of recovery orientation. This requires mutual discussion and the more active involvement of MHSUs in the design of their own rehabilitation process. Introduction Studies show

    Mental health policy stipulates seclusion should only be used as an intervention of last resort and for the minimum possible duration. Current evidence details which service users are more likely to be secluded, why they are secluded, and what influences the decision to seclude them. However, very little is known about the decision to release service users from seclusion. An integrative review was undertaken to explore the decision-making processes of mental health professionals which guide the ending of seclusion. The review used a systematic approach to gather and thematically analyse evidence within a framework approach. The twelve articles identified generated one overriding theme, maintaining safety. In addition, several subthemes emerged including the process of risk assessing which was dependent upon interaction and control, mediated by factors external to the service user such as the attitude and experience of staff and the acuity of the environment. Service users were expected to demonstrate compliance with the process ultimately ending in release and reflection. Little evidence exists regarding factors influencing mental health professionals in decisions to release service users from seclusion. There is no evidence-based risk assessment tool, and service users are not routinely involved in the decision to release them. Support from experienced professionals is vital to ensure timely release from seclusion. Greater insight into influences upon decisions to discontinue episodes may support initiatives aimed at reducing durations and use of seclusion. © 2018 Australian College of Mental Health Nurses Inc.

    Full Text Available Workplace violence is present in many work sectors, but in the area of mental health, nurses have a higher risk due to the close relationship they have with users. This study analyzed hostile user statements against nursing professionals of Mental Health Services and Emergency Units in Health Service (MHS hospitals in Murcia, Spain, and determined the frequency of exposure to the different violent user behaviors. The study was carried out with a sample of 518 nursing professionals from four hospital services: Mental Health, Emergency Units, Medical Hospitalization, and Maternal-and-Child. The nursing staff of Mental Health and Emergency Units was the most exposed to violence. Non-physical violence was more frequent in Emergency Units, whereas physical violence was more frequent in Mental Health. Among the consequences of exposure to non-physical violence are workers’ emotional exhaustion and the presence of psychological distress.

  1. [A New Challenge of Working Together: Psychiatry and Heraing Voices].

    Science.gov (United States)

    Laval, Christian

    Recovery model, as the hearing voices movement, promotes the users discourse among the health workers. This interference of users in the expertise considering the meaning of their voices is faced with the vision of advocating health workers, particularly the psychiatrists supporting the psychiatric users movement. On the field, this association seems challenging. On the experimental site in Marseille, professionals through various tensions and practical difficulties tend to reconsider their power / knowledge. This new challenge of working together leads them to adopt both a more humble position towards their clinical expertise and a more ambitious position regarding their participation in the construction of public controversies highlighted by the speaking experience of the hearing voices movement.

    2014-12-01

    The objective of this article is to analyze relationships between health professionals and users from a gender perspective. Using Pierre Bourdieu as a theoretical reference, we critically analyze data from two studies carried out in Brazil in which we took part as authors. The first of these studies was based in Rio de Janeiro and the second was a multicenter and ethnographical study carried out in eight health care facilities distributed throughout four Brazilian states, two in the Southeast region and two in the Northeast region. Among the principal results of the present study, we found that although the relationships between health professionals and users demonstrate varied opinions, all are marked by a gendered habitus. We conclude that, among other aspects, the construction of diverse femininities and masculinities and the way in which these are exercised in health care contexts are the product of process that is both socio-historical and personal.

  4. EQUIP training the trainers: an evaluation of a training programme for service users and carers involved in training mental health professionals in user-involved care planning.

    Fraser, C; Grundy, A; Meade, O; Callaghan, P; Lovell, K

    2017-08-01

    WHAT IS KNOWN ON THE SUBJECT?: UK NHS policy highlights the importance of user and carer involvement in health professional training. We know little about service user and carer motivations and experiences of accessing training courses for delivering training to health professionals and how well such courses prepare them for delivering training to healthcare professionals. 'Involvement' in training has often been tokenistic and too narrowly focused on preregistration courses. There is limited data on how best to prepare and support potential service user and carer trainers. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This study adds to the international literature by highlighting service user and carer motivations for accessing a training course for delivering training to health professionals. Service users and carers wanted to gain new skills and confidence in presentation/facilitation as well as to make a difference to healthcare practice. We also learned that service users desired different levels of involvement in training facilitation - some wanted to take a more active role than others. A one-size-fits-all approach is not always appropriate. Encountering resistance from staff in training was a previously unidentified challenge to service user and carers' experience of delivering training in practice and is a key challenge for trainers to address in future. Professional training involvement can be enhanced via specialist training such as the EQUIP training the trainers programme evaluated here. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: When training service users and carers to deliver training to mental health professionals, it is important that service users are equipped to deal with resistance from staff. It is important that service user and carer roles are negotiated and agreed prior to delivering training to healthcare professionals to accommodate individual preferences and allay anxieties. Training for service users and carers must be offered

    Social Networking Sites (SNS) have seen exponential growth in recent years. The high utilisation of SNS by tertiary students makes them an attractive tool for educational institutions. This study aims to identify health professional students' use and behaviours with SNS, including students' perspectives on potential applications within health professional curricula. Students enrolled in an undergraduate physiotherapy program were invited to take part in an anonymous, online questionnaire at the end of 2012. The survey consisted of 20 items, gathering demographic data, information on current use of SNS, and opinions regarding the application of SNS into education. Both quantitative and qualitative data were gathered. A total of 142 students, from all years of study, completed the online questionnaire. Only two participants were not current users of social media. Facebook and YouTube had been utilised for educational purposes by 97 and 60 % of participants respectively; 85 % believed that SNS could benefit their learning experience. Only five respondents were not interested in following peers, academic staff, clinicians or professional associations on Facebook. Four key themes emerged: peer collaboration, need for separation between personal and professional realms, complimentary learning and enhanced communication. Students wish to make educational connections via SNS, yet expressed a strong desire to maintain privacy, and a distinction between personal and professional lives. Educational utilisation of SNS may improve communication speed and accessibility. Any educator involvement should be viewed with caution.

    The main aim of this study was to identify the experiences of professionals in nongovernmental organizations (NGO) in Catalonia (Spain) working in HIV/AIDS prevention and control activities and potential areas of improvement of these activities and their evaluation. A further aim was to characterize the experiences, knowledge and practices of users of these organizations with regard to HIV infection and its prevention. A phenomenological qualitative study was conducted with the participation of both professionals and users of Catalan nongovernmental organizations (NGO) working in HIV/AIDS. Theoretical sampling (professional) and opportunistic sampling (users) were performed. To collect information, the following techniques were used: four focus groups and one triangular group (professionals), 22 semi-structured interviews, and two observations (users). A thematic interpretive content analysis was conducted by three analysts. The professionals of nongovernmental organizations working in HIV/AIDS adopted a holistic approach in their activities, maintained confidentiality, had cultural and professional competence and followed the principles of equality and empathy. The users of these organizations had knowledge of HIV/AIDS and understood the risk of infection. However, a gap was found between knowledge, attitudes and behavior. NGO offer distinct activities adapted to users' needs. Professionals emphasize the need for support and improvement of planning and implementation of current assessment. The preventive activities of these HIV/AIDS organizations are based on a participatory health education model adjusted to people's needs and focused on empowerment. Copyright © 2010 SESPAS.

    2013-06-01

    Several studies have demonstrated a high prevalence of voice disorders in teachers, together with the personal, professional and economical consequences of the problem. Good primary prevention should be based on 3 aspects: 1) amelioration of classroom acoustics, 2) voice care programs for future professional voice users, including teachers and 3) classroom or portable amplification systems. The aim of the study was to assess the benefit obtained from the use of portable amplification systems by female primary school teachers in their occupational setting. Forty female primary school teachers attended a course about professional voice care, which comprised two theoretical lectures, each 60 min long. Thereafter, they were randomized into 2 groups: the teachers of the first group were asked to use a portable vocal amplifier for 3 months, till the end of school-year. The other 20 teachers were part of the control group, matched for age and years of employment. All subjects had a grade 1 of dysphonia with no significant organic lesion of the vocal folds. Most teachers of the experimental group used the amplifier consistently for the whole duration of the experiment and found it very useful in reducing the symptoms of vocal fatigue. In fact, after 3 months, Voice Handicap Index (VHI) scores in "course + amplifier" group demonstrated a significant amelioration (p = 0.003). The perceptual grade of dysphonia also improved significantly (p = 0.0005). The same parameters changed favourably also in the "course only" group, but the results were not statistically significant (p = 0.4 for VHI and p = 0.03 for perceptual grade). In teachers, and particularly in those with a constitutional weak voice and/or those who are prone to vocal fold pathology, vocal amplifiers may be an effective and low-cost intervention to decrease potentially damaging vocal loads and may represent a necessary form of prevention.

  11. (Un)organizing equal collaboration between users and professionals: on management of patient education in Norway.

    Science.gov (United States)

    Stokken, Roar

    2013-03-01

    This is an article about how patient education is managed in Norway, but it also addresses a matter of broader relevance that of how an organization imbued with a request for rational choices is able to take on board a contradictory ideology. In Norway, patient education under the auspice of hospitals is to be conducted as an equal collaboration between users and professionals, posing challenges to the ethos of rationally justified choices within the hospital sector. This calls for an exploration of how the organization copes with the contradictory demands. A theoretical approach on the basis of theories from Scandinavian institutional theory and science and technology studies, informed by documents, interviews and experiences from national, regional and local levels in Norway. The field of patient education is divided into three decoupled domains: one at management level, one at the practical level, and in the middle a domain that acts as an interface between management and practice. This interface mediates the relationship between ideas and practice, without making overt the fact that ideas might not be possible to put into practice and that practice might not reflect ideas. The decoupling of practice and management allows patient education as equal collaboration between users and professionals to thrive as an idea, not subjugated by practical challenges. Thus, it can exist as a guiding star that both management and practitioners can attune to, but this situation might now be threatened by the demand for quality assurance in the field. © 2011 Blackwell Publishing Ltd.

    Smithson, Janet; Jones, Ray B; Ashurst, Emily

    2012-03-21

    There is increasing interest in online collaborative learning tools in health education, to reduce costs, and to offer alternative communication opportunities. Patients and students often have extensive experience of using the Internet for health information and support, and many health organisations are increasingly trying out online tools, while many healthcare professionals are unused to, and have reservations about, online interaction. We ran three week-long collaborative learning courses, in which 19 mental health professionals (MHPs) and 12 mental health service users (MHSUs) participated. Data were analysed using a discursive approach to consider the ways in which participants interacted, and how this contributed to the goal of online learning about using Internet technologies for mental health practice. MHSUs and MHPs were able to discuss issues together, listening to the views of the other stakeholders. Discussions on synchronous format encouraged participation by service users while the MHPs showed a preference for an asynchronous format with longer, reasoned postings. Although participants regularly drew on their MHP or MHSU status in discussions, and participants typically drew on either a medical expert discourse or a "lived experience" discourse, there was a blurred boundary as participants shifted between these positions. The anonymous format was successful in that it produced a "co-constructed asymmetry" which permitted the MHPs and MHSUs to discuss issues online, listening to the views of other stakeholders. Although anonymity was essential for this course to 'work' at all, the recourse to expert or lay discourses demonstrates that it did not eliminate the hierarchies between teacher and learner, or MHP and MHSU. The mix of synchronous and asynchronous formats helped MHSUs to contribute. Moderators might best facilitate service user experience by responding within an experiential discourse rather than an academic one.

    2017-10-09

    Purpose The purpose of this paper is to investigate the expectations and quality gaps in services provided at city public health clinics in the city of Natal, Brazil, from the perspective of patients and healthcare service providers. Design/methodology/approach The research sample consisted of 1,200 patients who used public health services and 265 providers - doctors, nutritionists, physiotherapists, psychologists, pharmacists and managers at three health clinics in the city of Natal, Brazil. A scale with 25 health service attributes was used in data collection. Summary statistics and t-test were used to analyze the data. Findings The results show that the providers think that users have lower levels of expectations than those indicated by the users in all attributes. Providers and users have the most approximate insights into what attributes are considered most important: explanations, level of knowledge and attention dispensed by health professionals. Users and providers perceived similar quality gaps for most of the attributes. The gaps were statistically the same, when comparing the mean quality shortcomings by means of a Student's test, considering a significance level of 5 percent, obtained independently by the manifestation of users and providers. Research limitations/implications The results reveal only a photograph of the moment. The study did not consider the differences that may exist between groups with different income levels, genders or age groups. A qualitative study could improve the understanding of the differences and coincidences of the diverse points of views. A more advanced research could even study possibilities so that health managers could promote changes in the service, some of them low cost, as the health professionals training for contact with patients. Practical implications The evaluation of the service quality complemented by the matrix of opportunities, importance × quality gaps generates information to help make decisions in the

    To investigate and determine the factors that enhanced or constituted barriers to the acceptance of an mHealth system which was piloted in Asante-Akim North District of Ghana to support healthcare of children. Four semi-structured focus group discussions were conducted with a total of 37 mothers. Participants were selected from a study population of mothers who subscribed to a pilot mHealth system which used an interactive voice response (IVR) for its operations. Data were evaluated using qualitative content analysis methods. In addition, a short quantitative questionnaire assessed system's usability (SUS). Results revealed 10 categories of factors that facilitated user acceptance of the IVR system including quality-of-care experience, health education and empowerment of women. The eight categories of factors identified as barriers to user acceptance included the lack of human interaction, lack of update and training on the electronic advices provided and lack of social integration of the system into the community. The usability (SUS median: 79.3; range: 65-97.5) of the system was rated acceptable. The principles of the tested mHealth system could be of interest during infectious disease outbreaks, such as Ebola or Lassa fever, when there might be a special need for disease-specific health information within populations. © 2017 John Wiley & Sons Ltd.

    Music teachers are over four times more likely than classroom teachers to develop voice disorders and greater than eight times more likely to have voice-related problems than the general public. Research has shown that individual voice-use parameters of phonation time, fundamental frequency and vocal intensity, as well as vocal load as calculated by cycle dose and distance dose are significantly higher for music teachers than their classroom teacher counterparts. Finding effective and inexpensive prophylactic measures to decrease vocal load for music teachers is an important aspect for voice preservation for this group of professional voice users. The purpose of this study was to determine the effects of voice amplification on vocal intensity and vocal load in the workplace as measured using a KayPENTAX Ambulatory Phonation Monitor (APM) (KayPENTAX, Lincoln Park, NJ). Seven music teachers were monitored for 1 workweek using an APM to determine average vocal intensity (dB sound pressure level [SPL]) and vocal load as calculated by cycle dose and distance dose. Participants were monitored a second week while using a voice amplification unit (Asyst ChatterVox; Asyst Communications Company, Inc., Indian Creek, IL). Significant decreases in mean vocal intensity of 7.00-dB SPL (Pmusic teachers in the classroom. Copyright © 2011 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    Background As a professional voice user, it is imperative that a speech-language pathologist's (SLP) vocal effectiveness remain consistent throughout the day. Many factors may contribute to reduced vocal effectiveness, including prolonged voice use, vocally abusive behaviours, poor vocal hygiene and environmental factors. Objectives To determine the effect of service delivery on the perceptual and acoustic features of voice. Method A quasi-experimental., pre-test–post-test research design was used. Participants included third- and final-year speech-language pathology students at the University of Pretoria (South Africa). Voice parameters were evaluated in a pre-test measurement, after which the participants provided two consecutive hours of therapy. A post-test measurement was then completed. Data analysis consisted of an instrumental analysis in which the multidimensional voice programme (MDVP) and the voice range profile (VRP) were used to measure vocal parameters and then calculate the dysphonia severity index (DSI). The GRBASI scale was used to conduct a perceptual analysis of voice quality. Data were processed using descriptive statistics to determine change in each measured parameter after service delivery. Results A change of clinical significance was observed in the acoustic and perceptual parameters of voice. Conclusion Guidelines for SLPs in order to maintain optimal vocal effectiveness were suggested. PMID:26304213

    Teachers, as professional voice users, are at particular risk of voice disorders. Among contributing factors, stress and psychological tension could play a role but epidemiological data on this problem are scarce. The aim of this study was to evaluate prevalence and cofactors of voice disorders among teachers in the French National Education system, with particular attention paid to the association between voice complaint and psychological status. The source data come from an epidemiological postal survey on physical and mental health conducted in a sample of 20,099 adults (in activity or retired) selected at random from the health plan records of the national education system. Overall response rate was 53%. Of the 10,288 respondents, 3,940 were teachers in activity currently giving classes to students. In the sample of those with complete data (n = 3,646), variables associated with voice disorders were investigated using logistic regression models. Studied variables referred to demographic characteristics, socio-professional environment, psychological distress, mental health disorders (DSM-IV), and sick leave. One in two female teachers reported voice disorders (50.0%) compared to one in four males (26.0%). Those who reported voice disorders presented higher level of psychological distress. Sex- and age-adjusted odds ratios [95% confidence interval] were respectively 1.8 [1.5-2.2] for major depressive episode, 1.7 [1.3-2.2] for general anxiety disorder, and 1.6 [1.2-2.2] for phobia. A significant association between voice disorders and sick leave was also demonstrated (1.5 [1.3-1.7]). Voice disorders were frequent among French teachers. Associations with psychiatric disorders suggest that a situation may exist which is more complex than simple mechanical failure. Further longitudinal research is needed to clarify the comorbidity between voice and psychological disorders.

    In implementing mobile health interventions, user requirements and willingness to use are among the most crucial concerns for success of the investigation and have only rarely been examined in sub-Saharan Africa. This study aimed to specify the requirements of caregivers of children in order to use a symptom-based interactive voice response (IVR) system for seeking healthcare. This included (i) the investigation of attitudes towards mobile phone use and user experiences and (ii) the assessment of facilitators and challenges to use the IVR system. This is a population-based cross-sectional study. Four qualitative focus group discussions were conducted in peri-urban and rural towns in Shai Osudoku and Ga West district, as well as in Tema- and Accra Metropolitan Assembly. Participants included male and female caregivers of at least one child between 0 and 10 years of age. A qualitative content analysis was conducted for data analysis. Participants showed a positive attitude towards the use of mobile phones for seeking healthcare. While no previous experience in using IVR for health information was reported, the majority of participants stated that it offers a huge advantage for improvement in health performance. Barriers to IVR use included concerns about costs, lack of familiarly with the technology, social barriers such as lack of human interaction and infrastructural challenges. The establishment of a toll-free number as well as training prior to IVR system was discussed for recommendation. This study suggests that caregivers in the socio-economic environment of Ghana are interested and willing to use mobile phone-based IVR to receive health information for child healthcare. Important identified users' needs should be considered by health programme implementers and policy makers to help facilitate the development and implementation of IVR systems in the field of seeking healthcare.

    Teachers are professional voice users, always at high risk of developing voice disorders due to high vocal demand and unfavorable environmental conditions. This study aimed at identifying possible correlations between teachers' voice symptoms and their perception of noise, the location of schools, as well as the location and conditions of their classrooms. One hundred forty teachers (ages 21-56) from schools in Upper Egypt participated in this study. They filled out a questionnaire including questions about the severity and frequency of their voice symptoms, noise perception, and the location and conditions of their schools and classrooms. Questionnaire responses were statistically analyzed to identify possible correlations. There were significant correlations (P Egyptian schools. This study may help future studies that focus on developing guidelines for the better planning of Egyptian schools in terms of improved infrastructure and architecture, thus considering the general and vocal health of teachers.

    2013-03-01

    Nursing faculty play an important role in constructing learning environments that foster the positive formation of future nurses. The students' construction of a nursing identity is grounded in social interactions with faculty and is shaped by values and norms learned in both the formal and informal curriculum. The informal curriculum is communicated in faculty teaching practices and relationships established with students. To acquire an understanding of the students' lived experience in associate degree nursing education and identify educational practices that support students' professional formation. A phenomenological design was chosen to study the lived experience of nursing education. In-depth interviews were conducted with 13 participants. Five students participated in second interviews for a total of 18 interviews. Symbolic interactionism guided data analysis. Participants represented three ADN programs in the northeastern U.S. and were diverse in terms of gender and age and to a lesser extent race, and sexual orientation. Faculty incivility included demeaning experiences, subjective evaluation, rigid expectations, and targeting and weeding out practices. Targeting practices contributed to a perceived focus on clinical evaluation and inhibited clinical learning. Faculty incivility hindered professional formation by interfering with learning, self-esteem, self-efficacy, and confidence. Faculty who model professional values in the formal and hidden curriculum contribute to the positive formation of future nurses. Nursing faculty should be formally prepared as educators to establish respectful, connected relationships with students. Faculty should role model professional values, deemphasize their evaluative role, provide constructive formative feedback, and remain open to the student's potential for growth.

    Current mental health policy emphasizes the importance of community-based service delivery for people with mental health problems to encompass personal recovery. The aim of this study is to explore how users and professionals construct the place's influence on personal recovery in community mental health services. This is a qualitative, interpretive study based on ten individual, semi-structured interviews with users and professionals, respectively. A discourse analysis inspired by the work of Foucault was used to analyze the interviews. The findings show how place can be constructed as a potential for and as a barrier against recovery. Constructions of the aim of the services matter when choosing a place for the services. Further, constructions of user-professional relationships and flexibility are important in the constructions of an appropriate place for the services. The aim of the service, the user-professional relationship, and flexibility in choosing place were essential in the participants' constructions. To find "the right place" for mental health services was constructed as context-sensitive and complex processes of assessment and co-determination. Trial registration The study is approved by the Regional Committee for Medical Research Ethics, Norway (REK-Midt 2011/2057).

    2017-07-01

    Although being personal in relationships with service users is commonly described as an important aspect of the way that professionals help people with severe mental problems, this has also been described to bring with it a need to keep a distance and set boundaries. This study aims to explore how professionals working in psychiatric care view being personal in their relationships with users. Qualitative interviews with 21 professionals working in three outpatient psychiatric units, analyzed through thematic analysis. Being personal in their relationships with users was described as something that participants regarded to be helpful, but that also entails risks. Participants described how they balanced being personal by keeping a distance and maintaining boundaries in their relationships based on their "experience-based knowledge" to counter these risks. While these boundaries seemed to play an important part in the way that they act and behave, they were not seen as fixed, but rather as flexible and dynamic. Boundaries could sometimes be transgressed to the benefit of users. Being personal was viewed as something that may be helpful to users, but that also entails risks. Although boundaries may be a useful concept for use in balancing these risks, they should be understood as something complex and flexible.

    Full Text Available The aim of this survey was to gather data from both implant recipients and professionals on the ease of use of the Naída CI Q70 (Naída CI sound processor from Advanced Bionics and on the usefulness of the new functions and features available. A secondary objective was to investigate fitting practices with the new processor. A comprehensive user satisfaction survey was conducted in a total of 186 subjects from 24 centres. In parallel, 23 professional questionnaires were collected from 11 centres. Overall, there was high satisfaction with the Naída CI processor from adults, children, experienced and new CI users as well as from professionals. The Naída CI processor was shown as being easy to use by all ages of recipients and by professionals. The majority of experienced CI users rated the Naída CI processor as being similar or better than their previous processor in all areas surveyed. The Naída CI was recommended by the professionals for fitting in all populations. Features like UltraZoom, ZoomControl and DuoPhone would not be fitted to very young children in contrast to adults. Positive ratings were obtained for ease of use, comfort and usefulness of the new functions and features of the Naída CI sound processor. Seventy-seven percent of the experienced CI users rated the new processor as being better than their previous sound processor from a general point of view. The survey also showed that fitting practices were influenced by the age of the user.

    Occurrence of professional dysphonia was analysed in a group of 309 patients treated in the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical Academy in Białystok through the period of 1999-2001. In a group of professional voice users female teachers of primary schools and lower secondary schools predominated. Obtained results were compared with those from a group of 65 persons of other occupations. In the both groups other harmful factors affecting the voice organ were excluded. The clinical assessment included subjective and objective laryngological examination using videolaryngostroboscopy. The clinical material was evaluated in a view of functional and organic disorders of the voice organ. Early occurrence and aggravation of functional changes in the larynx was recorded in non professional voice users in the course of their seniority. In professional patients organic changes were more common and occurred earlier than functional disorders. Severity of dysphonia was related to the larynx pathology, especially of a functional character.

  12. Dependence and resistance in community mental health care-Negotiations of user participation between staff and users.

    Femdal, I; Knutsen, I R

    2017-10-01

    WHAT IS KNOWN ON THE SUBJECT?: Implementation of user participation is described as a change from a paternalistic healthcare system to ideals of democratization where users' voices are heard in relational interplays with health professionals. The ideological shift involves a transition from welfare dependency and professional control towards more active service-user roles with associated rights and responsibilities. A collaborative relationship between users and professionals in mental health services is seen as important by both parties. Nevertheless, the health professionals find it challenging in practice to reorient their roles and to find productive ways to cooperate. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study illuminates how user participation is negotiated and involves multiple and shifting subject positions in the collaboration between users and professionals in community mental health care. By taking different positions, the relationship between users and professionals develops through dynamic interaction. This study challenges understandings of equality and implicit "truths" in user participation by illuminating subtle forms of power and dilemmas that arise in user-professional negotiations. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Instead of denying the appearance of power, it is important to question the execution of power in the interplay between users and professionals. Focusing on the negotiation processes between users and professionals is important for increasing reflection on and improving understanding of the dynamic in collaboration and speech. By focusing on negotiations, power can be used in productive ways in user-professional relationships. Introduction Implementation of user participation is considered important in today's mental health care. Research shows, however, that user participation lacks clarity and provokes uncertainty regarding shifting roles. Aim To investigate negotiation of user participation in a microstudy of

    Most voice self-rating tools are disease-specific measures and are not suitable for use with healthy voice users. There is a need for a tool that is sensitive to the subtleties of a singer's voice and to perceived physical changes in the singing voice mechanism as a function of load. The aim of this study was to devise and validate a scale to assess singer's perceptions of the current status of their singing voice. Ninety-five vocal health descriptors were collected from focus group interviews of singers. These were reviewed by 25 currently performing music theater (MT) singers. Based on a consensus technique, the number of descriptors was decreased to 42 items. These were administered to a sample of 284 professional MT singers using an online survey to evaluate their perception of current singing voice status. Principal component analysis identified two subsets of items. Rasch analysis was used to evaluate and refine these sets of items to form two 10-item subscales. Both subscales demonstrated good overall fit to the Rasch model, no differential item functioning by sex or age, and good internal consistency reliability. The two subscales were strongly correlated and subsequent Rasch analysis supported their combination to form a single 20-item scale with good psychometric properties. The Evaluation of the Ability to Sing Easily (EASE) is a concise clinical tool to assess singer's perceptions of the current status of their singing voice with good measurement properties. EASE may prove a useful tool to measure changes in the singing voice as indicators of the effect of vocal load. Furthermore, it may offer a valuable means for the prediction or screening of singers "at risk" of developing voice disorders. Copyright © 2013 The Voice Foundation. All rights reserved.

    Remote programming is safe and is well received by health-care professionals and cochlear implant (CI) users. It can be adopted into clinic routine as an alternative to face-to-face programming. Telemedicine allows a patient to be treated anywhere in the world. Although it is a growing field, little research has been published on its application to CI programming. We examined hearing professionals' and CI users' subjective reactions to the remote programming experience, including the quality of the programming and the use of the relevant technology. Remote CI programming was performed in Italy, Sweden, and Russia. Programming sessions had three participants: a CI user, a local host, and a remote expert. After the session, each CI user, local host, and remote expert each completed a questionnaire on their experience. In all, 33 remote programming sessions were carried out, resulting in 99 completed questionnaires. The overwhelming majority of study participants responded positively to all aspects of remote programming. CI users were satisfied with the results in 96.9% of the programming sessions; 100% of participants would use remote programming again. Although technical problems were encountered, they did not cause the sessions to be considerably longer than face-to-face sessions.

    2002-08-01

    The main aim of the study was to undertake training needs analysis among a multi-professional group for the purpose of improving care for ethnic minority patients and other service users. Evidence from the literature identifies that some of the explanations advanced for the failure of health professionals to meet the needs of ethnic minorities include lack of understanding of cultural diversities, racism, racial stereotyping, lack of knowledge, exclusivity, and ethnocentrism. While these issues have been addressed in different countries, little work has been carried out to examine these from the perspective of health professionals caring for ethnic minorities. This study is therefore an attempt to find out what health professionals know about caring for patients and other service users from minority ethnic groups and their perception of training needs in this area of work. A pre- and post-training design phase structured the qualitative approach. A purposive sample of individuals working across five health service organizations located in a multi-racial city yielded a multi-professional group of participants. Views of 22 participants were obtained by semi-structured interviews at a pretraining phase. Training needs of health professionals drew on Walklin's (1992) six stages used to structure data collection, data analysis and delivery of training. The post-training phase used questionnaires to evaluate immediate learning that based on a 4-week period of reflection and applied to practice. The questionnaires were complemented by a facilitator-lead focus group. The majority of the participants confirmed that no attention was given in their initial education to the health care needs of minority ethnic groups. Instead, participants engaged in self-initiated learning to improve their knowledge and understanding. The issue of communication was viewed with dissatisfaction and seen as affecting the sufficiency of caring for these patients. All participants rated meeting

    2012-02-01

    OBJECTIVES AND HYPOTHESIS: Anecdotal evidence suggests that tonsillectomy has no deleterious consequences on a person\\'s voice under normal vocal demand. However, whether the enlarged dimensions of the oropharynx after tonsillectomy impair the quality of a professional voice user remains unclear. Therefore, we designed a study to determine whether adult tonsillectomy altered the resonance characteristics of the vocal tract in any way and whether these changes were transient or permanent. STUDY DESIGN: This is a prospective observational study with full institutional ethical approval. METHODS: All adult patients presenting for tonsillectomy for recurrent tonsillitis in our institution were recruited. Their voice was recorded preoperatively, postoperatively, and at 4 weeks postoperatively. The values of the first four formants were calculated in all recordings. The oropharyngeal dimensions were measured preoperatively and postoperatively. Tonsillar weights and volumes were also measured. RESULTS: The first formant was noted to rise postoperatively. The average value of F2 and F3 did not alter postoperatively or at 4 weeks. However, it was noted that the fourth formant was not universally present preoperatively but was present in all patients postoperatively and at 4 weeks. CONCLUSIONS: Altering the dimensions of the oropharynx after tonsillectomy causes the first formant to rise but has no effect on the third and fourth formants. However, the fourth formant appears in patients who previously did not demonstrate it. The fourth formant was present in a greater proportion of male patients preoperatively than female patients, but it was universally present postoperatively and at 4 weeks in both sexes. This suggests that increasing the horizontal dimensions of the oropharynx has a nontransient effect on the higher order formants of the voice.

    In many Western countries, options for citizens to influence public services are increased to improve the quality of services and democratize decision making. Possibilities to influence are often cast into Albert Hirschman's taxonomy of exit (choice), voice, and loyalty. In this article we identify delegation as an important addition to this framework. Delegation gives individuals the chance to practice exit/choice or voice without all the hard work that is usually involved in these options. Empirical research shows that not many people use their individual options of exit and voice, which could lead to inequality between users and nonusers. We identify delegation as a possible solution to this problem, using Dutch health care as a case study to explore this option. Notwithstanding various advantages, we show that voice and choice by delegation also entail problems of inequality and representativeness.

    2013-10-01

    Full Text Available We have recently been witnessing the growing establishment of map-centered web-based geo-portals on national, regional and local levels. However, a particular issue with these geo-portals is that each instance has been implemented in different ways in terms of design, usability, functionality, interaction possibilities, map size and symbologies. In this paper, we try to tackle these shortcomings by analyzing and formalizing the requirements for map-based geo-portals in a user experience based approach. First, we propose a holistic definition the term of a “geo-portal”. Then, we present our approach to user experience design for map-based geo-portals by defining the functional requirements of a geo-portal, by analyzing previous geo-portal developments, by distilling the results of our empirical user study to perform practically-oriented user requirements, and finally by establishing a set of user experience design guidelines for the creation of map-based geo-portals. These design guidelines have been extracted for each of the main components of a geo-portal, i.e., the map, the search dialogue, the presentation of the search results, symbologies, and other aspects. These guidelines shall constitute the basis for future geo-portal developments to achieve standardization in the user-experience design of map-based geo-portals.

    Nowadays minor surgery is performed by di- fferent professionals at primary as well as specialized care. Being a healthcare technology, minor surgery must be assessed in order to achieve an organizational efficiency. User's satisfaction must be one of the quality criteria. That is why an analysis of the quality perceived by users according to where minor surgery takes place and who carries it out is made. This study explores, conducting telephone surveys, the satisfaction of a sample of 275 minor surgery patients of two hospitals and three primary healthcare areas of Asturias. The survey is based on the SERVQUAL model adapting the one used by the Spanish Ministry of Health in 1977. A behavior pattern of satisfaction was established in terms of the variables that increase or diminish it. In every item, satisfaction was perceived as good or very good at least in 84% of the survey users and in the majority was over 95%. There was a significant difference in favour of primary care with respect to waiting time (p less than 0,001), explanations received (p=0,002) and security perceived (p=0,015). The more explanatory variables of excellent satisfaction were the sense of security and the staff attention. The kind of professional did not represent a conditioning factor and the level of healthcare only appeared to be so among those who did not feel safe showing to be less satisfied those treated in primary care. Good quality perceived by users does not seem to be penalized by the fact that minor surgery can be carried out at different healthcare levels or which specialist performs it.

    Voice disorders are very prevalent among teachers and consequences are serious. Although the literature is extensive, there are differences in the concepts and methodology related to voice problems; most studies are restricted to analyzing the responses of teachers to questionnaires and only a few studies include vocal assessments and videolaryngoscopic examinations to obtain a definitive diagnosis. To review demographic studies related to vocal disorders in teachers to analyze the diverse methodologies, the prevalence rates pointed out by the authors, the main risk factors, the most prevalent laryngeal lesions, and the repercussions of dysphonias on professional activities. The available literature (from 1997 to 2013) was narratively reviewed based on Medline, PubMed, Lilacs, SciELO, and Cochrane library databases. Excluded were articles that specifically analyzed treatment modalities and those that did not make their abstracts available in those databases. The keywords included were teacher, dysphonia, voice disorders, professional voice. Copyright © 2014 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    A non-acoustic sensor is used to measure a user's speech and then broadcasts an obscuring acoustic signal diminishing the user's vocal acoustic output intensity and/or distorting the voice sounds making them unintelligible to persons nearby. The non-acoustic sensor is positioned proximate or contacting a user's neck or head skin tissue for sensing speech production information.

    To analyse changes in health professionals' and immigrant users' perceptions of the quality of care provided to the immigrant population during the crisis. A qualitative descriptive-interpretative and exploratory study was conducted in two areas of Catalonia. Semi-structured individual interviews were used with a theoretical sample of medical (n=24) and administrative (n=10) professionals in primary care (PC) and secondary care (SC), and immigrant users (n=20). Thematic analysis was conducted and the results were triangulated. Problems related to technical and interpersonal quality emerged from the discourse of both professionals and immigrants. These problems were attributed to cutbacks during the economic crisis. Regarding technical quality, respondents reported an increase in erroneous or non-specific diagnoses, inappropriate use of diagnostic tests and non-specific treatments, due to reduction in consultation times as a result of cuts in human resources. With regard to interpersonal quality, professionals reported less empathy, and users also reported worse communication, due to changes in professionals' working conditions and users' attitudes. Finally, a reduction in the resolution capacity of the health services emerged: professionals described unnecessary repeated PC visits and limited responses in SC, while young immigrants reported an insufficient response to their health problems. The results indicate a deterioration in perceived technical and interpersonal quality during the economic crisis, due to cutbacks mainly in human resources. These changes affect the whole population, but especially immigrants. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Nutritional education is a participatory process of knowledge acquisition concerning a healthy diet. The implementation of nutritional education in the public health care system is put into question based on a survey carried out with health professionals, and with users of one Basic Health Care Unit (UBS. The execution of nutritional education requires health professional specific knowledge in order to approach alimentary problems. The nutritionist is not duly involved in the public health care. Based on quantitative and qualitative methodologies, eight UBS health professionals were interviewed in order to verify their professional and personal experiences concerning nutritional education. There were 306 users interviewed, which is a representative sample of the population which is assisted by the UBS, in order to analyze the influence of such activity in their health. The interview results show that the professionals have some difficulty in approaching information concerning alimentation and that they believe there is some room for a nutritionist's participation in a multi-disciplinary team. Around 97% of the users believe that nutrition interferes in their life quality and 19.28% of them believe that nutrition problems are related to education. Nutritional education, as a structured program, does not exist. The mobilization of nutritionists in the exercise of their function and in meeting demands of health professionals and health care users is necessary.

    The Greek mental health system has been undergoing radical reforms for over the past twenty years. In congruence with trends and practices in other European countries, Greek mental health reforms were designed to develop a community-based mental health service system. The implementation of an extensive transformation became possible through the "Psychargos" program, a national strategic and operational plan, which was developed by the Ministry of Health and Social Solidarity. The Psychargos program was jointly funded by the European Union by 75% of the cost over a period of 5 years and the Greek State. After the period of 5 years, the entire cost of the new services became the responsibility of the Greek National Budget. Over the years the Psychargos program became almost synonymous with the deinstitutionalisation of long term psychiatric patients with the development of a wide range of community mental health services. The Psychargos program ended in December 2009. This article presents the views of service providers and service users as part an ex-post evaluation of the Psychargos program carried out in 2010. Data derived for this part of the evaluation are from the application of the qualitative method of focus groups. The outcomes of the study identified several positive and noteworthy achievements by the reforms of the Greek mental health system as well as weaknesses. There was considerable similarity of the views expressed by both focus groups. In addition the service users' focus group emphasized more issues related to improving their mental health wellbeing and living a satisfying, hopeful, and contributing life.

    Full Text Available Objective: analyze  profile of users of primary health care services affected by leprosy, as well as the medical professionals and nurses responsible for the follow - up of these patients.   Methods: This is a field study that surveyed the socioeconomic and clinical profile of 26 patients affected by leprosy, attended at the municipal health units of the urban area of ​​Teresina-PI, as well as the professional profile and clinical practices of 15 physicians and 19 nurses responsible for the follow-up of these patients. Results: It was observed a profile of people affected by leprosy, characterized by: individuals aged 50 years or more; predominantly male; with low schooling and income. The clinical characteristics reveal a high prevalence of multibacillary cases of leprosy and with a significant diagnosis of some degree of physical disability. Regarding the profile of the professionals and their clinical behaviors, it was verified that the majority had post-graduation and a long time of experience in primary health care and leprosy control actions, however, it has been shown that they do not always put into practice all actions necessary for the diagnosis and treatment of the disease. Conclusions: The profile of patients with leprosy treated at the municipal health units in the urban area of Teresina was similar to that found in other Brazilian territories, thus evidencing the need to implement public social support policies and more effective diagnostic and therapeutic follow-up practices by reduce the high rates of endemicity of the disease.

    Teachers are more prone to develop voice problems (VPs) when compared with other professional voice users. The aim of present study was to investigate the prevalence and risk factors of VPs among primary school teachers in India. Epidemiological cross-sectional survey. Self-reporting questionnaire data were collected from 1082 teachers. Out of 1082 teachers who participated in the present study, 188 teachers reported VPs that account for a prevalence rate of 17.4%. Tired voice after long hours of talking was the most frequently reported symptom, followed by sore/dry throat, strain in voice, neck muscle tension, and difficulty in projecting voice. The adjusted odds ratio values showed number of years of teaching, high background noise levels in the classroom, experiencing psychological stress while teaching classes, improper breath management (holding breath while speaking), poor focus of the tone (clenching jaw/teeth while speaking), upper respiratory tract infection, thyroid problems, and acid reflux as significant risk factors for the development of VPs in the current cohort of teachers. Current results suggest that teachers develop VPs due to multiple risk factors. These factors may be either biological, psychomotor, or environment-related factors. A holistic approach (which could include educating teachers about voice care during their training, and if they develop VP during their career, then managing the VP by taking into consideration different risk factors) addressing all these factors needs to be adopted to prevent VPs in primary school teachers.

    The prevalence of voice disorders in the teacher population in Latvia has not been studied so far and this is the first epidemiological study whose goal is to investigate the prevalence of voice disorders and their risk factors in this professional group. A wide cross-sectional study using stratified sampling methodology was implemented in the general education schools of Latvia. The self-administered voice risk factor questionnaire and the Voice Handicap Index were completed by 522 teachers. Two teachers groups were formed: the voice disorders group which included 235 teachers with actual voice problems or problems during the last 9 months; and the control group which included 174 teachers without voice disorders. Sixty-six percent of teachers gave a positive answer to the following question: Have you ever had problems with your voice? Voice problems are more often found in female than male teachers (68.2% vs 48.8%). Music teachers suffer from voice disorders more often than teachers of other subjects. Eighty-two percent of teachers first faced voice problems in their professional carrier. The odds of voice disorders increase if the following risk factors exist: extra vocal load, shouting, throat clearing, neglecting of personal health, background noise, chronic illnesses of the upper respiratory tract, allergy, job dissatisfaction, and regular stress in the working place. The study findings indicated a high risk of voice disorders among Latvian teachers. The study confirmed data concerning the multifactorial etiology of voice disorders.

    Full Text Available Voice of vocal professionals is exposed to great temptations, i.e. there is a high probability of voice alterations. Smoking, allergies and respiratory infections greatly affect the voice, which can change its acoustic characteristics. In smokers, the vocal cords mass increases, resulting in changes in vocal fold vibratory cycle. Pathological changes of vocal folds deform the acoustic signal and affect voice production. As vocal professionals, teachers are much more affected by voice disorders than average speakers. The aim of this study was to examine the differences in acoustic parameters of voice between smoking and nonsmoking teachers, in a sample of vocal professionals. The sample consisted of 60 female subjects, aged from 25 to 59. For voice analysis we used Computer lab, model 4300, 'Kay Elemetrics Corporation'. The statistical significance of differences in the values of acoustic parameters between smokers and nonsmokers was tested by ANOVA. Results showed that in the sample of female teachers, professional use of voice combined with the smoking habit can be linked to the changes in voice parameters. Comparing smokers and nonsmokers, average values of the parameters in short-term and long-term disturbances of frequency and amplitude proved to be significantly different.

    2012-01-01

    Background: Awareness of radiological risk is low among doctors and patients. An educational/decision tool that considers each patient’ s cumulative lifetime radiation exposure would facilitate provider–patient communication. Aim: The purpose of this work was to develop user-friendly software for simple estimation and communication of radiological risk to patients and doctors as a part of the SUIT-Heart (Stop Useless Imaging Testing in Heart disease) Project of the Tuscany Region. Methods: We developed a novel software program (PC-platform, Windows OS fully downloadable at (http://suit-heart.ifc.cnr.it)) considering reference dose estimates from American Heart Association Radiological Imaging 2009 guidelines and UK Royal College of Radiology 2007 guidelines. Cancer age and gender-weighted risk were derived from Biological Effects of Ionising Radiation VII Committee, 2006. Results: With simple input functions (demographics, age, gender) the user selects from a predetermined menu variables relating to natural (e.g., airplane flights and geo-tracked background exposure), professional (e.g., cath lab workers) and medical (e.g., CT, cardiac scintigraphy, coronary stenting) sources. The program provides a simple numeric (cumulative effective dose in milliSievert, mSv, and equivalent number of chest X-rays) and graphic (cumulative temporal trends of exposure, cancer cases out of 100 exposed persons) display. Conclusions: A simple software program allows straightforward estimation of cumulative dose (in multiples of chest X-rays) and risk (in extra % lifetime cancer risk), with simple numbers quantifying lifetime extra cancer risk. Pictorial display of radiation risk may be valuable for increasing radiological awareness in cardiologists.

    The objective of disease screening is to encourage high-risk subjects to seek health care diagnosis and treatment. Mobile phone apps can effectively screen mental health conditions, including depression. However, it is not known how effective such screening methods are in motivating users to discuss the obtained results of such apps with health care professionals. Does a mobile phone depression-screening app motivate users with high depressive symptoms to seek health care professional advice? This study aimed to address this question. This was a single-cohort, prospective, observational study of a free mobile phone depression app developed in English and released on Apple's App Store. Apple App Store users (aged 18 or above) in 5 countries, that is, Australia, Canada, New Zealand (NZ), the United Kingdom (UK), and the United States (US), were recruited directly via the app's download page. The participants then completed the Patient Health Questionnaire (PHQ-9), and their depression screening score was displayed to them. If their score was 11 or above and they had never been diagnosed with depression before, they were advised to take their results to their health care professional. They were to follow up after 1 month. A group of 2538 participants from the 5 countries completed PHQ-9 depression screening with the app. Of them, 322 participants were found to have high depressive symptoms and had never been diagnosed with depression, and received advice to discuss their results with health care professionals. About 74% of those completed the follow-up; approximately 38% of these self-reported consulting their health care professionals about their depression score. Only positive attitude toward depression as a real disease was associated with increased follow-up response rate (odds ratio (OR) 3.2, CI 1.38-8.29). A mobile phone depression-screening app motivated some users to seek a depression diagnosis. However, further study should investigate how other app users use

    The design and deployment of complex technologies like the electronic health record (EHR) involve technical, personal, social, and organizational issues. The Brazilian public and private scenario includes different local and regional initiatives for implementation of the electronic health record. The Brazilian Ministry of Health also has a proposal to develop a national EHR. The current study aimed to provide a comprehensive view of perceptions by health system administrators, professionals, and users concerning their experiences with the electronic health record and their opinions of the possibility of developing a national EHR. This qualitative study involved 28 semi-structured interviews. The results revealed both the diversity of factors that can influence the implementation of an electronic health record and the existence of convergences and aspects that tend to be valued differently according to the different points of view. Key aspects include discussions on the electronic health record's attributes and it impact on healthcare, especially in the case of local electronic health records, concerns over costs and confidentiality and privacy pertaining to electronic health records in general, and the possible implications of centralized versus decentralized data storage in the case of a national EHR. The interviews clearly showed the need to establish more effective communication among the various stakeholders, and that the different perspectives should be considered when drafting and deploying an EHR at the local, regional, and national levels.

    Access to care for eating disorders can be problematic for numerous reasons including lack of understanding and delays with treatment referrals. Previous research has highlighted the benefits of telephone helplines as an accessible source of support for those who may not wish to access face-to-face support or to fill a gap for those waiting for treatment. This study aimed to gain an insight into the perspectives of those who may use or refer others to a telephone helpline in order to identify the requirements of such a service. Triangulation of service user, carer and health professionals' perspectives resulted in identification of themes relating to the type of support, delivery and practicalities of a helpline. The findings indicated that telephone helplines may offer numerous benefits for individuals with an eating disorder, whether accessed as a first step, alongside treatment or as an extension of this support when in recovery. Additionally helplines may provide an opportunity for carers to access information and discuss their own experiences, while supporting their loved one. Raising awareness of these services is important to encourage those affected by an eating disorder to access and make the most of this type of support. These findings offer an insight into the key requirements for new and existing service development with regard to both the type of support and the method of communication required by individuals with eating disorders.

    Voice assistants are software agents that can interpret human speech and respond via synthesized voices. Apple's Siri, Amazon's Alexa, Microsoft's Cortana, and Google's Assistant are the most popular voice assistants and are embedded in smartphones or dedicated home speakers. Users can ask their assistants questions, control home automation devices and media playback via voice, and manage other basic tasks such as email, to-do lists, and calendars with verbal commands. This column will explore the basic workings and common features of today's voice assistants. It will also discuss some of the privacy and security issues inherent to voice assistants and some potential future uses for these devices. As voice assistants become more widely used, librarians will want to be familiar with their operation and perhaps consider them as a means to deliver library services and materials.

    Given the rising popularity of voice and video services over the Internet, accurately identifying voice and video traffic that traverse their networks has become a critical task for Internet service providers (ISPs). As the number of proprietary applications that deliver voice and video services to end users increases over time, the search for the one methodology that can accurately detect such services while being application independent still remains open. This problem becomes even more complicated when voice and video service providers like Skype, Microsoft, and Google bundle their voice and video services with other services like file transfer and chat. For example, a bundled Skype session can contain both voice stream and file transfer stream in the same layer-3/layer-4 flow. In this context, traditional techniques to identify voice and video streams do not work. In this paper, we propose a novel self-learning classifier, called VVS-I , that detects the presence of voice and video streams in flows with minimum manual intervention. Our classifier works in two phases: training phase and detection phase. In the training phase, VVS-I first extracts the relevant features, and subsequently constructs a fingerprint of a flow using the power spectral density (PSD) analysis. In the detection phase, it compares the fingerprint of a flow to the existing fingerprints learned during the training phase, and subsequently classifies the flow. Our classifier is not only capable of detecting voice and video streams that are hidden in different flows, but is also capable of detecting different applications (like Skype, MSN, etc.) that generate these voice/video streams. We show that our classifier can achieve close to 100% detection rate while keeping the false positive rate to less that 1%.

    Full Text Available Assistance to users of alcohol and other drugs in Brazil has undergone several transformations owing to historical, social, and political phenomena. In 2009, the Ministry of Health created the ‘Street Clinic’ in order to reduce harm to the homeless and the population vulnerable to use of alcohol or other drugs. The aim of this study was to describe and analyze the experience at a ‘Street Clinic’ from the perspective of the professionals who compose the service team in a municipality located in the metropolitan region of Recife, Pernanbuco state. This is a qualitative study with data collected through semi-structured interviews with five professionals and submitted to qualitative analysis. The content of the interviews explained the dynamic character of the reality experienced by professionals and the time of implementation and consolidation of this service in the city, characterizing the objectives, clientele, user demand, and systematization of actions and difficulties in delivering the service. It was possible to identify similarities between the experiences of the research participants and what is recommended by the Ministry of Health, as well as similarities with other services described in the literature. Furthermore, the data revealed the day to day challenges experienced by the professionals expressed mainly in the difficulties reported in the interviews. The study provided a good basis for the implementation of other Street Clinic teams and the training of professionals, including occupational therapists, to work in this field.

    It has been established that mental health-care planning does not adequately respond to the needs of those accessing services. Understanding the reasons for this and identifying whose needs care plans serve requires an exploration of the perspectives of service users, carers and professionals within the wider organizational context. To explore the current operationalization of care planning and perceptions of its function within mental health services from the perspectives of multiple stakeholders. Participants included 21 mental health professionals, 29 service users and 4 carers from seven Mental Health Trusts in England. All participants had experience of care planning processes within secondary mental health-care services. Fifty-four semi-structured interviews were conducted with participants and analysed utilizing a qualitative framework approach. Care plans and care planning were characterized by a failure to meet the complexity of mental health needs, and care planning processes were seen to prioritize organizational agendas and risk prevention which distanced care planning from the everyday lives of service users. Care planning is recognized, embedded and well established in the practices of mental health professionals and service users. However, it is considered too superficial and mainly irrelevant to users for managing mental health in their everyday lives. Those responsible for the planning and delivery of mental health services should consider ways to increase the relevance of care planning to the everyday lives of service users including separating risk from holistic needs assessment, using support aids and utilizing a peer workforce in this regard. © 2017 The Authors Health Expectations published by John Wiley & Sons Ltd.

    This study focuses on speaking voice quality in male teachers (n = 35) and male actors (n = 36), who represent untrained and trained voice users, because we wanted to investigate normal and supranormal voices. In this study, both substantial and methodologic aspects were considered. It includes a method for perceptual voice evaluation, and a basic issue was rater reliability. A listening group of 10 listeners, 7 experienced speech-language therapists, and 3 speech-language therapist students evaluated the voices by 15 vocal characteristics using VA scales. Two sets of voice signals were investigated: text reading (2 loudness levels) and sustained vowel (3 levels). The results indicated a high interrater reliability for most perceptual characteristics. Connected speech was evaluated more reliably, especially at the normal level, but both types of voice signals were evaluated reliably, although the reliability for connected speech was somewhat higher than for vowels. Experienced listeners tended to be more consistent in their ratings than did the student raters. Some vocal characteristics achieved acceptable reliability even with a smaller panel of listeners. The perceptual characteristics grouped in 4 factors reflected perceptual dimensions.

    This study concerns speaking voice quality in a group of male teachers (n = 35) and male actors (n = 36), as the purpose was to investigate normal and supranormal voices. The goal was the development of a method of valid perceptual evaluation for normal to supranormal and resonant voices. The voices (text reading at two loudness levels) had been evaluated by 10 listeners, for 15 vocal characteristics using VA scales. In this investigation, the results of an exploratory factor analysis of the vocal characteristics used in this method are presented, reflecting four dimensions of major importance for normal and supranormal voices. Special emphasis is placed on the effects on voice quality of a change in the loudness variable, as two loudness levels are studied. Furthermore, the vocal characteristics Sonority and Ringing voice quality are paid special attention, as the essence of the term "resonant voice" was a basic issue throughout a doctoral dissertation where this study was included.

    The objective of the present study was to evaluate the effectiveness of the application of homeovox for the combined treatment of small vocal cord nodules and acute laryngitis in the professional voice users. A total of 40 subjects presenting with dysphonia were examined after they were divided into two study groups and two groups of comparison depending on the nosological form of the pathological condition. The subjects comprising the study groups were given traditional therapy in the combination with the intake of homeovox whereas the patients included in the two groups of comparison received the traditional treatment alone. The outcome of the treatment was evaluated on days 1, 5, and 10 after the initiation of therapy based on the analysis of the changes in the videoendostroboscopic picture of the larynx and the acoustic characteristics obtained by the computer-assisted analysis of the voice. The analysis of the results of the combined treatment has demonstrated the statistically significant differences in some acoustic parameters of the voice between the subjects with small vocal cord nodules and acute laryngitis belonging to the study groups and the groups of comparison. It is concluded that the introduction of homeovox in the combined treatment of the patients presenting with the small nodules in the vocal cords and acute catarrhal laryngitis accelerates the recovery of the acoustic characteristics of the voice within various periods after the onset of the treatment in comparison with the patients treated with the use of traditional therapy alone.

    The development of effective health care and public health interventions requires a comprehensive understanding of the perceptions, concerns, and stated needs of health care consumers and the public at large. Big datasets from social media and question-and-answer services provide insight into the public's health concerns and priorities without the financial, temporal, and spatial encumbrances of more traditional community-engagement methods and may prove a useful starting point for public-engagement health research (infodemiology). The objective of our study was to describe user characteristics and health-related queries of the ChaCha question-and-answer platform, and discuss how these data may be used to better understand the perceptions, concerns, and stated needs of health care consumers and the public at large. We conducted a retrospective automated textual analysis of anonymous user-generated queries submitted to ChaCha between January 2009 and November 2012. A total of 2.004 billion queries were read, of which 3.50% (70,083,796/2,004,243,249) were missing 1 or more data fields, leaving 1.934 billion complete lines of data for these analyses. Males and females submitted roughly equal numbers of health queries, but content differed by sex. Questions from females predominantly focused on pregnancy, menstruation, and vaginal health. Questions from males predominantly focused on body image, drug use, and sexuality. Adolescents aged 12-19 years submitted more queries than any other age group. Their queries were largely centered on sexual and reproductive health, and pregnancy in particular. The private nature of the ChaCha service provided a perfect environment for maximum frankness among users, especially among adolescents posing sensitive health questions. Adolescents' sexual health queries reveal knowledge gaps with serious, lifelong consequences. The nature of questions to the service provides opportunities for rapid understanding of health concerns and may

    The objective of this review is to identify and synthesize the best international qualitative evidence on healthcare users' experiences of communication with healthcare professionals about children who have life-limiting conditions. For the purposes of this review, "healthcare users" will be taken to include children who have life-limiting conditions and their families. The question to be addressed is:What are healthcare users' experiences of communicating with healthcare professionals about children who have life-limiting conditions? The prospect of the death of a child from an incurable medical condition is harrowing, yet finding a way to discuss this prospect is crucial to maximize the quality of life for such children and their families. High-quality communication is well recognized as a core skill health care professionals need to maximize the quality of care they provide. This skill is valued by service users, who consistently rate it as one of the highest priorities for the care they receive. Evidence suggests, however, that healthcare professionals can feel ill-equipped or uncomfortable communicating with and about such children. Therefore, it is important to understand what represents high-quality communication and what is involved in accomplishing this within pediatric palliative care.In recent decades there has been an increased focus on providing palliative care for children who have life-limiting conditions. These are conditions for which no cure is available and for which the probable outcome is premature death. Palliative care may also be appropriate for children who have life-threatening conditions; these are conditions where there is not only a high probability of premature death but also a chance of long-term survival into adulthood Although pediatric palliative care is underpinned by the same philosophy as adult palliative care, children who have life-limiting conditions and their families have particular needs that distinguish them from users of

    WHAT IS KNOWN ON THE SUBJECT?: There is consistent evidence that service users and carers feel marginalized in the process of mental health care planning. Mental health professionals have identified ongoing training needs in relation to involving service users and carers in care planning. There is limited research on the acceptability of training packages for mental health professionals which involve service users and carers as co-facilitators. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: A co-produced and co-delivered training package on service user- and carer-involved care planning was acceptable to mental health professionals. Aspects of the training that were particularly valued were the co-production model, small group discussion and the opportunity for reflective practice. The organizational context of care planning may need more consideration in future training models. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health nurses using co-production models of delivering training to other mental health professionals can be confident that such initiatives will be warmly welcomed, acceptable and engaging. On the basis of the results reported here, we encourage mental health nurses to use co-production approaches more often. Further research will show how clinically effective this training is in improving outcomes for service users and carers. Background There is limited evidence for the acceptability of training for mental health professionals on service user- and carer-involved care planning. Aim To investigate the acceptability of a co-delivered, two-day training intervention on service user- and carer-involved care planning. Methods Community mental health professionals were invited to complete the Training Acceptability Rating Scale post-training. Responses to the quantitative items were summarized using descriptive statistics (Miles, ), and qualitative responses were coded using content analysis (Weber, ).

    Consumer research reveals considerable interest in the use of Personal Health Records (PHRs), yet adoption remains relatively low. Both adopters and nonadopters represent important perspectives from which to understand this paradox. This study focuses on direct feedback from adopters obtained using the American Customer Satisfaction Index (ACSI) survey on the My HealtheVet PHR portal (http://www.myhealth.va.gov) of the Veterans Health Administration (VHA). The results represent a source of direct feedback with which to better understand veterans' needs and preferences. The ACSI Survey was implemented in October 2007 to measure satisfaction and elicit information about characteristics and preferences of My HealtheVet PHR adopters. The data represent a continuous random sample of site visitors who have navigated at least four pages on the site. A total of 100 617 surveys were completed (17.2%). Satisfaction with My HealtheVet is high (8.3/10.0), and users are highly likely to return to the site (8.6/10.0) and recommend the site to other veterans (9.1/10.0). The majority of system adopters are male (91%), between the ages of 51 and 70 (68%), and served in the Vietnam War (60%). Most veterans currently visit the site to utilize pharmacy-related features. VHA has used the ACSI to monitor satisfaction, and to better understand the characteristics, needs, and preferences of early adopters. The data provide an important source of direct feedback to inform program development. Future research will include monitoring the impact of enhancements and new features on satisfaction, and conducting additional research with nonadopters to identify barriers to adoption and use.

    Shared decision making (SMD) related to treatment and rehabilitation is considered a central component in recovery-oriented practice. Although decision aids are regarded as an essential component for successfully implementing SDM, these aids are often lacking within psychiatric services. The aim of this study was to use a participatory design to facilitate the development of a user-generated, web-based decision aid for individuals receiving psychiatric services. The results of this effort as well as the lessons learned during the development and usability processes are reported. The participatory design included 4 iterative cycles of development. Various qualitative methods for data collection were used with potential end users participating as informants in focus group and individual interviews and as usability and pilot testers. Interviewing and testing identified usability problems that then led to refinements and making the subsequent prototypes increasingly user-friendly and relevant. In each phase of the process, feedback from potential end-users provided guidance in developing the formation of the web-based decision aid that strengthens the position of users by integrating access to information regarding alternative supports, interactivity between staff and users, and user preferences as a continual focus in the tool. This web-based decision aid has the potential to strengthen service users' experience of self-efficacy and control as well as provide staff access to user knowledge and preferences. Studies employing participatory models focusing on usability have potential to significantly contribute to the development and implementation of tools that reflect user perspectives.

    Developing programs and actions to fight stigma and discrimination against people living with mental disorders is a priority both internationally and in France. Involving mental health service users in these anti-stigma programs has proved to be a key element for effective programs. The present study evaluates the impact of user-trainers in an anti-stigma campaign with job counselors on their knowledge, beliefs, and desire for social distance with regard to mental illness and the mentally ill. Eighty-nine professionals participated in eight mental health awareness days from December 2008 to June 2009. Each training day was built around two pedagogical units: firstly, a psychiatrist providing a theoretical overview of mental illness and care and secondly, user-trainers describing their point of view on mental illness and exchanging with participants. A questionnaire administered at the beginning and at the end of the mental health awareness day assessed the impact of the day on participants' knowledge, beliefs, and desire for social distance. Answers to open questions were evaluated using thematic qualitative analysis. The intervention had statistically significant positive effects on all three training objectives: knowledge, beliefs and desire for social distance. Analysis of qualitative data confirmed participants' need for information and training with regard to providing support to clients with mental health problems; participants frequently attributed their improved self-confidence at the end of the day with regard to providing job coaching for this population group to the presence of user-trainers. A mental health awareness day using mental health service users and psychiatrists as trainers had significant positive effects in terms of reducing stigma with regard to people with mental illness. Further research is needed to understand whether the impact of such awareness approaches can be maintained in everyday professional practice over time. Copyright © 2013

    The purpose of this paper is to explore how healthcare-users' engagement is perceived, how it occurs and how these perceptions differ between three European countries: England, Poland and Slovenia, using the concepts of voice, choice and coproduction. This comparative, qualitative study is based on a review of legal documents, academic literature and semi-structured interviews conducted in October and November 2011. A research sample consisted of 21 interviewees representing various stakeholders including healthcare-users, doctors and managers. Primary and secondary data were analysed using theoretical thematic analysis. Emerging themes were identified from the interviews and related to the indicators describing healthcare-users' involvement in the voice, choice and coproduction model. Results of the comparative qualitative research suggest that the healthcare-users' influence is strongly grounded in England where the healthcare system and professionals are prepared to include healthcare-users in the decision-making process. In Slovenia, cultural development of healthcare-users' involvement seems to proceed the institutional development. In Poland, institutions are ready to involve healthcare-users in decision-making process although the cultural desirability of involving users among doctors and patients is lacking. The notion of user involvement is increasingly gaining importance and research attention, yet there is still little known about the way cultural, political, historical differences between various European countries influence it. This paper explores this little known area using the original approach of user involvement (Dent et al., 2011) with input from various stakeholders including patients, healthcare representatives and academics.

    The objectives of this study were to describe singing voice therapy (SVT), describe referred patient characteristics, and document the outcomes of SVT. Retrospective. Records of patients receiving SVT between June 2008 and June 2013 were reviewed (n = 51). All diagnoses were included. Demographic information, number of SVT sessions, and symptom severity were retrieved from the medical record. Symptom severity was measured via the 10-item Singing Voice Handicap Index (SVHI-10). Treatment outcome was analyzed by diagnosis, history of previous training, and SVHI-10. SVHI-10 scores decreased following SVT (mean change = 11, 40% decrease) (P singing lessons (n = 10) also completed an average of three SVT sessions. Primary muscle tension dysphonia (MTD1) and benign vocal fold lesion (lesion) were the most common diagnoses. Most patients (60%) had previous vocal training. SVHI-10 decrease was not significantly different between MTD and lesion. This is the first outcome-based study of SVT in a disordered population. Diagnosis of MTD or lesion did not influence treatment outcomes. Duration of SVT was short (approximately three sessions). Voice care providers are encouraged to partner with a singing voice therapist to provide optimal care for the singing voice. This study supports the use of SVT as a tool for the treatment of singing voice disorders. 4 Laryngoscope, 126:2546-2551, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    Development of more self-management support programmes in primary health care has been one option used to enhance positive outcomes in chronic disease management. At present, research results provide no consensus on what would be the best way to develop support programmes into new settings. The aim of the present study was therefore to explore users' and health professionals' perceptions of what would be the vital elements in a self - management support programme applicable in primary health care, how to account for them, and why. Four qualitative, semi-structured focus group interviews were conducted in Central Norway. The informants possessed experience in development, provision, or participation in a self-management support programme. Data was analysed by the Systematic Text Condensation method. The results showed an overall positive expectation to the potential benefits of development of a self-management support programme in primary health care. Despite somewhat different arguments and perspectives, the users and the health professionals had a joint agreement on core characteristics; a self-management support programme in primary health care should therefore be generic, not disease specific, and delivered in a group- based format. A special focus should be on the everyday- life of the participants. The most challenging aspect was a present lack of competence and experience among health professionals to moderate self-management support programmes. The development and design of a relevant and applicable self-management support programme in primary health care should balance the interests of the users with the possibilities and constraints within each municipality. It would be vital to benefit from the closeness of the patients' every-day life situations. The user informants' perception of a self-management support programme as a supplement to regular medical treatment represented an expanded understanding of the self-management support concept.

    Evidence from European and American studies indicates limited referrals of people with learning (intellectual) disabilities to palliative care services. Although professionals' perceptions of their training needs in this area have been studied, the perceptions of people with learning disabilities and family carers are not known. This study aimed to elicit the views of people with learning disabilities, and their family carers concerning palliative care, to inform healthcare professional education and training. A qualitative, exploratory design was used. A total of 17 people with learning disabilities were recruited to two focus groups which took place within an advocacy network. Additionally, three family carers of someone with a learning disability, requiring palliative care, and two family carers who had been bereaved recently were also interviewed. Combined data identified the perceived learning needs for healthcare professionals. Three subthemes emerged: 'information and preparation', 'provision of care' and 'family-centred care'. This study shows that people with learning disabilities can have conversations about death and dying, and their preferred end-of-life care, but require information that they can understand. They also need to have people around familiar to them and with them. Healthcare professionals require skills and knowledge to effectively provide palliative care for people with learning disabilities and should also work in partnership with their family carers who have expertise from their long-term caring role. These findings have implications for educators and clinicians. Published by the BMJ Publishing Group Limited.

    Stoicheff, M.L.

    1975-01-01

    This study was undertaken to provide information on the voice of patients following radiotherapy for glottic cancer. Part I presents findings from questionnaires returned by 227 of 235 patients successfully irradiated for glottic cancer from 1960 through 1971. Part II presents preliminary findings on the speaking fundamental frequencies of 22 irradiated patients. Normal to near-normal voice was reported by 83 percent of the 227 patients; however, 80 percent did indicate persisting vocal difficulties such as fatiguing of voice with much usage, inability to sing, reduced loudness, hoarse voice quality and inability to shout. Amount of talking during treatments appeared to affect length of time for voice to recover following treatments in those cases where it took from nine to 26 weeks; also, with increasing years since treatment, patients rated their voices more favorably. Smoking habits following treatments improved significantly with only 27 percent smoking heavily as compared with 65 percent prior to radiation therapy. No correlation was found between smoking (during or after treatments) and vocal ratings or between smoking and length of time for voice to recover. There was no relationship found between reported vocal ratings and stage of the disease

    Research has found relational qualities of power and intimacy to exist within hearer-voice interactions. The present study aimed to provide a deeper understanding of the interpersonal context of voice hearing by exploring participants' relationships with their voices and other people in their lives. This research was designed in consultation with service users and employed a qualitative, phenomenological, and idiographic design using semi-structured interviews. Ten participants, recruited via mental health services, and who reported hearing voices in the previous week, completed the interviews. These were transcribed verbatim and analysed using interpretative phenomenological analysis. Five themes resulted from the analysis. Theme 1: 'person and voice' demonstrated that participants' voices often reflected the identity, but not always the quality of social acquaintances. Theme 2: 'voices changing and confirming relationship with the self' explored the impact of voice hearing in producing an inferior sense-of-self in comparison to others. Theme 3: 'a battle for control' centred on issues of control and a dilemma of independence within voice relationships. Theme 4: 'friendships facilitating the ability to cope' and theme 5: 'voices creating distance in social relationships' explored experiences of social relationships within the context of voice hearing, and highlighted the impact of social isolation for voice hearers. The study demonstrated the potential role of qualitative research in developing theories of voice hearing. It extended previous research by highlighting the interface between voices and the social world of the hearer, including reciprocal influences of social relationships on voices and coping. Improving voice hearers' sense-of-self may be a key factor in reducing the distress caused by voices. ©2010 The British Psychological Society.

    The purpose of this study was to compare the perceptual examination of voice quality with the condition of the vocal folds and voice complaints during voice screening in female student teachers. This research was a cross-sectional study in 214 starting student teachers using the four-point grade scale of the GRBAS and laryngostroboscopic assessment of the vocal folds. The voice quality was assessed by speech pathologists using the ordinal 4-point G-scale (overall dysphonia) of the GRBAS method in a running speech sample. Glottal closure and vocal fold lesions were recorded. A questionnaire was used for assessing voice complaints. More students with an insufficient glottal closure (89%) were rated dysphonic compared with students with sufficient glottal closure (80%). Students with sufficient glottal closure had a significantly lower mean G-score (1.21) compared with the group with insufficient glottal closure (1.52) (P = 0.038). This study showed a larger percentage of students with vocal fold lesions (96%) labeled a dysphonic voice compared to students with no vocal fold problems (81%). Students with no vocal fold lesions had a significantly lower mean G-score (1.20) compared with the group with vocal fold lesions (2.05) (P=0.002). A dysphonic voice (G≥1) was rated in 76% of the students without voice complaints compared with 86% of the students with voice complaints. Students with no voice complaints had a lower mean G-score (1.07) compared with the group with voice complaints (1.41) (P=0.090). The present study showed that perceptual assessment of the voice and voice complaints is not sufficient to check if the future professional is at risk. Therefore, preventive measures are needed to detect students at risk early in their education and this depends on broader assessment: on the one hand, assessing voice quality and voice complaints and on the other hand, examination of the vocal folds of all starting students.

    Full Text Available This paper examines the effect of voice quality on hiring decisions. Considering voice quality an important tool in an individual’s self-presentation in the job market, it may very well enhance his/her job prospects, while some voice qualities may affect employers’ judgments in a negative way. Five men and five women were recorded reading four different utterances representing answers to job interviewers’ questions in four different phonation guises: modal, breathy, creaky and pressed. 38 professional employment interviewers recorded the speakers’ hireability and personality ratings (likeability, self-confidence and trustworthiness on 7-point semantic differential scales based on the speakers’ voice. The results revealed a significant effect of the phonation guises on the speakers’ ratings with the modal voice being superior to the cluster of non-modal voices. Interestingly, the non-modal guises were evaluated in a very similar way, except for the self-confidence category with the breathy voice getting the lowest scores on the one hand and the pressed voice correlating with high self-confidence ratings on the other.

  20. Can a voice disorder be an occupational disease?

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available Voice disorders are all changes in the voice quality that can be detected by hearing. Some etiological factors that contribute to the development of voice disorders are related to occupation, working environment and working conditions. In modern societies one third of the labour force works in professions with vocal loading. In such professions, voice disorders influence work ability and quality of life. For an occupational disease, the exposure to harmful factors in the workplace is essential and causes the development of a disorder in a previously healthy individual. In some European countries, voice disorders in teachers, which do not improve after proper treatment are recognized as occupational diseases. In Slovenia, no organic or functional voice disorder is listed on the current list of occupational diseases. Prevention and cure of occupational voice disorders can contribute to better safety at the workplace and improve the workers’ health. Voice professionals must also know that they are responsible for their own health and that they must actively take care of it.

    Full Text Available Control systems driven by voice recognition software have been implemented before but lacked the context driven approach to generate relevant responses and actions. A partially voice activated control system for mobile robotics is presented that allows an autonomous robot to interact with people and the environment in a meaningful way, while dynamically creating customized tours. Many existing control systems also require substantial training for voice application. The system proposed requires little to no training and is adaptable to chaotic environments. The traversable area is mapped once and from that map a fully customized route is generated to the user

    2014-09-01

    Full Text Available Scientific task for improving the signal-to-noise ratio for user’s voice signal in computer systems and networks during the process of user’s voice authentication is considered. The object of study is the process of input and extraction of the voice signal of authentication system user in computer systems and networks. Methods and means for input and extraction of the voice signal on the background of external interference signals are investigated. Ways for quality improving of the user’s voice signal in systems of voice authentication are investigated experimentally. Firmware means for experimental unit of input and extraction of the user’s voice signal against external interference influence are considered. As modern computer means, including mobile, have two-channel audio card, two microphones are used in the voice signal input. The distance between sonic-wave sensors is 20 mm and it provides forming one direction pattern lobe of microphone array in a desired area of voice signal registration (from 100 Hz to 8 kHz. According to the results of experimental studies, the usage of directional properties of the proposed microphone array and space-time processing of the recorded signals with implementation of constant and adaptive weighting factors has made it possible to reduce considerably the influence of interference signals. The results of firmware experimental studies for input and extraction of the user’s voice signal against external interference influence are shown. The proposed solutions will give the possibility to improve the value of the signal/noise ratio of the useful signals recorded up to 20 dB under the influence of external interference signals in the frequency range from 4 to 8 kHz. The results may be useful to specialists working in the field of voice recognition and speaker discrimination.

  4. Speaking in Character: Voice Communication in Virtual Worlds

    Science.gov (United States)

    Wadley, Greg; Gibbs, Martin R.

    This chapter summarizes 5 years of research on the implications of introducing voice communication systems to virtual worlds. Voice introduces both benefits and problems for players of fast-paced team games, from better coordination of groups and greater social presence of fellow players on the positive side, to negative features such as channel congestion, transmission of noise, and an unwillingness by some to use voice with strangers online. Similarly, in non-game worlds like Second Life, issues related to identity and impression management play important roles, as voice may build greater trust that is especially important for business users, yet it erodes the anonymity and ability to conceal social attributes like gender that are important for other users. A very different mixture of problems and opportunities exists when users conduct several simultaneous conversations in multiple text and voice channels. Technical difficulties still exist with current systems, including the challenge of debugging and harmonizing all the participants' voice setups. Different groups use virtual worlds for very different purposes, so a single modality may not suit all.

  5. Voice - How humans communicate?

    Voices are important things for humans. They are the medium through which we do a lot of communicating with the outside world: our ideas, of course, and also our emotions and our personality. The voice is the very emblem of the speaker, indelibly woven into the fabric of speech. In this sense, each of our utterances of spoken language carries not only its own message but also, through accent, tone of voice and habitual voice quality it is at the same time an audible declaration of our membership of particular social regional groups, of our individual physical and psychological identity, and of our momentary mood. Voices are also one of the media through which we (successfully, most of the time) recognize other humans who are important to us-members of our family, media personalities, our friends, and enemies. Although evidence from DNA analysis is potentially vastly more eloquent in its power than evidence from voices, DNA cannot talk. It cannot be recorded planning, carrying out or confessing to a crime. It cannot be so apparently directly incriminating. As will quickly become evident, voices are extremely complex things, and some of the inherent limitations of the forensic-phonetic method are in part a consequence of the interaction between their complexity and the real world in which they are used. It is one of the aims of this article to explain how this comes about. This subject have unsolved questions, but there is no direct way to present the information that is necessary to understand how voices can be related, or not, to their owners.

    2012-11-01

    The aim of the study was to investigate the connections between voice ergonomic risk factors found in classrooms and voice-related problems in teachers. Voice ergonomic assessment was performed in 39 classrooms in 14 elementary schools by means of a Voice Ergonomic Assessment in Work Environment--Handbook and Checklist. The voice ergonomic risk factors assessed included working culture, noise, indoor air quality, working posture, stress, and access to a sound amplifier. Teachers from the above-mentioned classrooms reported their voice symptoms, respiratory tract diseases, and completed a Voice Handicap Index (VHI). The more voice ergonomic risk factors found in the classroom the higher were the teachers' total scores on voice symptoms and VHI. Stress was the factor that correlated most strongly with voice symptoms. Poor indoor air quality increased the occurrence of laryngitis. Voice ergonomics were poor in the classrooms studied and voice ergonomic risk factors affected the voice. It is important to convey information on voice ergonomics to education administrators and those responsible for school planning and taking care of school buildings.

    2007-05-01

    This paper is a report of a study to evaluate the development of an innovative Service User Academic post in mental health nursing in relation to student learning and good employment practice in terms of social inclusion. Institutions providing professional mental health education are usually expected to demonstrate user involvement in the design, delivery and evaluation of their educational programmes to ensure that user voices are central to the development of clinical practice. Involvement can take many forms but not everyone values user knowledge as equal to other sources of knowledge. This can lead to users feeling exploited, rather than fully integrated in healthcare professional education processes. Development of the post discussed in this paper was stimulated and informed by an innovative example from Australia. An observational case study of the development and practice of a Service User Academic post was undertaken in 2005. Participants were purposively sampled and included the User Academic, six members of a user and carer reference group, 10 educators and 35 students. Data were collected by group discussions and interviews. Data analysis was based on the framework approach. The evaluation revealed tangible benefits for the students and the wider academic community. Most important was the powerful role model the Service User Academic provided for students. The post proved an effective method to promote service user participation and began to integrate service user perspectives within the educational process. However, the attempts to achieve socially inclusive practices were inhibited by organizational factors. The expectations of the role and unintended discriminatory behaviours had an impact on achieving full integration of the role. Furthermore, shortcomings in the support arrangements were revealed. The search for an optimum model of involvement may prove elusive, but the need to research and debate different strategies, to avoid tokenism and

    To present a literature review about the Brazilian scientific production in Speech-Language Pathology and Audiology regarding voice in popular singing in the last decade, as for number of publications, musical styles studied, focus of the researches, and instruments used for data collection. Cross-sectional descriptive study carried out in two stages: search in databases and publications encompassing the last decade of researches in this area in Brazil, and reading of the material obtained for posterior categorization. The databases LILACS and SciELO, the Databasis of Dissertations and Theses organized by CAPES, the online version of Acta ORL, and the online version of OPUS were searched, using the following uniterms: voice, professional voice, singing voice, dysphonia, voice disorders, voice training, music, dysodia. Articles published between the years 2000 and 2010 were selected. The researches found were classified and categorized after reading their abstracts and, when necessary, the whole study. Twenty researches within the proposed theme were selected, all of which were descriptive, involving several musical styles. Twelve studies focused on the evaluation of the popular singer's voice, and the most frequently used data collection instrument was the auditory-perceptual evaluation. The results of the publications found corroborate the objectives proposed by the authors and the different methodologies. The number of studies published is still restricted when compared to the diversity of musical genres and the uniqueness of popular singer.

    2018-01-11

    The objectives of this study were to trace and describe research patterns in singing voice, to compare the amount of published research over time, to identify journals that published most papers on "singing voice," and to establish the most frequent research topics. The study uses qualitative and quantitative approaches through descriptive statistics, text mining, and clustering. The authors conducted a search to identify scientific papers. The titles and abstracts were analyzed regarding word frequency and relations between them, through hierarchical cluster analysis and co-occurrence networks. The frequency of journals was calculated, as well as the amount of papers across time. Since 1949, 754 papers were published and an increase was noticed. Even though 162 journals were identified by the authors, the Journal of Voice holds the majority of papers, in every analyzed period. An evolution of studied topics is described. Up to 2010, the main theme was professional singers, especially classical and opera interpreters. Since then, voice quality and the effects of training gathered more attention. The growing interest in singing has been conspicuous since the first indexed paper. However, it has been slightly slowing down. Until 2010, great importance was given to the voice quality of singers and their occupational demands. Acoustic analysis was widely used to study the effects of training. Since 2010, the concern with functionality is increasing, rather than the organic voice structures. Musical perception studies have been a trend, as well as the use of electroglottography.

    2018-04-01

    This paper, firstly, introduces the application trend of the integration of multi-channel interactions in automotive HMI ((Human Machine Interface) from complex information models faced by existing automotive HMI and describes various interaction modes. By comparing voice interaction and touch screen, gestures and other interaction modes, the potential and feasibility of voice interaction in automotive HMI experience design are concluded. Then, the related theories of voice interaction, identification technologies, human beings' cognitive models of voices and voice design methods are further explored. And the research priority of this paper is proposed, i.e. how to design voice interaction to create more humane task-oriented dialogue scenarios to enhance interactive experiences of automotive HMI. The specific scenarios in driving behaviors suitable for the use of voice interaction are studied and classified, and the usability principles and key elements for automotive HMI voice design are proposed according to the scenario features. Then, through the user participatory usability testing experiment, the dialogue processes of voice interaction in automotive HMI are defined. The logics and grammars in voice interaction are classified according to the experimental results, and the mental models in the interaction processes are analyzed. At last, the voice interaction design method to create the humane task-oriented dialogue scenarios in the driving environment is proposed.

    Emotion in audio-voice signals, as synthesized by text-to-speech (TTS) technologies, was investigated to formulate a theory of expression for user interface design. Emotional parameters were specified with markup tags, and the resulting audio was further modulated with post-processing techniques. Software was then developed to link a selected TTS synthesizer with an automatic speech recognition (ASR) engine, producing a chatbot that could speak and listen. Using these two artificial voice subsystems, investigators explored both artistic and psychological implications of artificial speech emotion. Goals of the investigation were interdisciplinary, with interest in musical composition, augmentative and alternative communication (AAC), commercial voice announcement applications, human-computer interaction (HCI), and artificial intelligence (AI). The work-in-progress points towards an emerging interdisciplinary ontology for artificial voices. As one study output, HCI tools are proposed for future collaboration.

    Speech enhancement is challenging task in audio signal processing to enhance the quality of targeted speech signal while suppress other noises. In the beginning, the speech enhancement algorithm growth rapidly from spectral subtraction, Wiener filtering, spectral amplitude MMSE estimator to Non-negative Matrix Factorization (NMF). Smartphone as revolutionary device now is being used in all aspect of life including journalism; personally and professionally. Although many smartphones have two microphones (main and rear) the only main microphone is widely used for voice recording. This is why the NMF algorithm widely used for this purpose of speech enhancement. This paper evaluate speech enhancement on smartphone voice recording by using some algorithms mentioned previously. We also extend the NMF algorithm to Kulback-Leibler NMF with supervised separation. The last algorithm shows improved result compared to others by spectrogram and PESQ score evaluation. (paper)

    The aim of this study was to assess the application of Voice Handicap Index (VHI) in the diagnosis of occupational voice disorders in female teachers. The subjective assessment of voice by VHI was performed in fifty subjects with dysphonia diagnosed in laryngovideostroboscopic examination. The control group comprised 30 women whose jobs did not involve vocal effort. The results of the total VHI score and each of its subscales: functional, emotional and physical was significantly worse in the study group than in controls (p teachers estimated their own voice problems as a moderate disability, while 12% of them reported severe voice disability. However, all non-teachers assessed their voice problems as slight, their results ranged at the lowest level of VHI score. This study confirmed that VHI as a tool for self-assessment of voice can be a significant contribution to the diagnosis of occupational dysphonia.

    We are all voice experts. First and foremost, we can produce and understand speech, and this makes us a unique species. But in addition to speech perception, we routinely extract from voices a wealth of socially-relevant information in what constitutes a more primitive, and probably more universal, non-linguistic mode of communication. Consider the following example: you are sitting in a plane, and you can hear a conversation in a foreign language in the row behind you. You do not see the speakers' faces, and you cannot understand the speech content because you do not know the language. Yet, an amazing amount of information is available to you. You can evaluate the physical characteristics of the different protagonists, including their gender, approximate age and size, and associate an identity to the different voices. You can form a good idea of the different speaker's mood and affective state, as well as more subtle cues as the perceived attractiveness or dominance of the protagonists. In brief, you can form a fairly detailed picture of the type of social interaction unfolding, which a brief glance backwards can on the occasion help refine - sometimes surprisingly so. What are the acoustical cues that carry these different types of vocal information? How does our brain process and analyse this information? Here we briefly review an emerging field and the main tools used in voice perception research. Copyright © 2011 Elsevier Ltd. All rights reserved.

    This study explores whether changes in voice- and swallow-related QoL are associated with progression of idiopathic Parkinson's disease (IPD). Furthermore, it examines the relationship between patients' perception of both voice and swallowing disorders in IPD. Prospective clinical study, quality of life (QoL). One-hundred mentally competent IPD patients with voice and swallowing complaints were asked to answer four QoL questionnaires (Voice Handicap Index, MD Anderson Dysphagia Inventory, Visual Analog Scale [VAS] voice, and Dysphagia Severity Scale [DSS]). Differences in means for the QoL questionnaires and their subscales within Hoehn and Yahr stage groups were calculated using one-way analysis of variance. The relationship between voice- and swallow-related QoL questionnaires was determined with the Spearman correlation coefficient. Scores on both voice and swallow questionnaires suggest an overall decrease in QoL with progression of IPD. A plateau in QoL for VAS voice and the DSS was seen in the early Hoehn and Yahr stages. Finally, scores on voice-related QoL questionnaires were significantly correlated with swallow-related QoL outcomes. Voice- and swallow-related QoL decreases with progression of IPD. A significant association was found between voice- and swallow-related QoL questionnaires. Healthcare professionals can benefit from voice- and swallow-related QoL questionnaires in a multidimensional voice- or swallow-assessment protocol. The patient's perception of his/her voice and swallowing disorders and its impact on QoL in IPD should not be disregarded. 2b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    If people are asked to discriminate visually the two individuals of a monozygotic twin (MT), they mostly get into trouble. Does this problem also exist when listening to twin voices? Twenty female and 10 male MT voices were randomly assembled with one "strange" voice to get voice trios. The listeners (10 female students in Speech and Language Pathology) were asked to label the twins (voices 1-2, 1-3 or 2-3) in two conditions: two standard sentences read aloud and a 2.5-second midsection of a sustained /a/. The proportion correctly labelled twins was for female voices 82% and 63% and for male voices 74% and 52% for the sentences and the sustained /a/ respectively, both being significantly greater than chance (33%). The acoustic analysis revealed a high intra-twin correlation for the speaking fundamental frequency (SFF) of the sentences and the fundamental frequency (F0) of the sustained /a/. So the voice pitch could have been a useful characteristic in the perceptual identification of the twins. We conclude that there is a greater perceptual resemblance between the voices of identical twins than between voices without genetic relationship. The identification however is not perfect. The voice pitch possibly contributes to the correct twin identifications.

    The paper analyzes voice disturbances, their causes and specific features in teachers based on the questionnaires filled by 934 general educational school teachers. The teachers have been found to associate voice disturbances not only with changes in the voice timbre, but with different subjective feelings that make their professional activity difficult. The major factors that cause voice disturbances are the voice overloads that differ in teachers of different specialities, their inability to use the voice, psychoemotional stresses, and frequent colds, as well as a combination of several factors. The incidence of vocal apparatus diseases does not tend to decrease, which makes it necessary to implement combined medical and pedagogical prophylactic measures to prevent dysphonia.

    Contemporary commercial music (CCM) performers rely heavily on their voice, yet may not be aware of the importance of proactive voice care. This investigation intends to identify perceptions and barriers to seeking voice care among CCM artists. This cross-sectional observational study used a 10-item Likert-based response questionnaire to assess current perceptions regarding voice care in a population of randomly selected participants of professional CCM conference. Subjects (n=78) were queried regarding their likelihood to seek medical care for minor medical problems and specifically problems with their voice. Additional questions investigated anxiety about seeking voice care from a physician specialist, speech language pathologist, or voice coach; apprehension regarding findings of laryngeal examination, laryngeal imaging procedures; and the effect of medical insurance on the likelihood of seeking medical care. Eighty-two percent of subjects reported that their voice was a critical part of their profession; 41% stated that they were not likely to seek medical care for problems with their voice; and only 19% were reluctant to seek care for general medical problems (Peducation about the importance of voice care is needed in this population of vocal performers.

    statistical analysis of the results was carried out, not distinguishing between those who use their voices professionally and those who don't. RESULTS: dysphonia had an impact on the quality of life of all patients. There was no statistically significant difference between the groups - professional users and non-users of their voices; however, considering the groups separately, this correlation was significant only in the group of patients who do not use their voices professionally. CONCLUSION: Dysphonia affected the quality of life of all subjects regardless of their voice use.

    Full Text Available The key epistemological assumption in participatory research is the belief that knowledge is embedded in the lives and experiences of individuals and that knowledge is developed only through a cooperative process between researchers and experiencing individuals. There are various notions about the nature and processes of participation in this type of research. This paper focuses on specific processes that are used for a "genuine" participation by experiencing individuals as research participants. It also identifies processes that are critical for researchers to engage with, in order to become pro-participatory in their approaches to qualitative research. The paper draws on a particular project as an exemplar—"The Crisis Resolution and Home Treatment Project." This project uses various participatory research processes to elicit and include voices of health-care professionals, service users, and family members. The main objective of the research project is to develop knowledge for new forms of community-based practices for people experiencing mental health crisis. We present the participatory research methodology applied in this research, and discuss two sets of processes used to enhance "participation" in research—one set to encourage and elicit participation by research participants; and the other set to engage researchers in reflection within the participatory research process. This will mitigate the paucity of literature regarding the processes and approaches necessary to make participatory research truly "participatory" both for research participants and researchers.

  13. Mapping Phonetic Features for Voice-Driven Sound Synthesis

    Science.gov (United States)

    Janer, Jordi; Maestre, Esteban

    In applications where the human voice controls the synthesis of musical instruments sounds, phonetics convey musical information that might be related to the sound of the imitated musical instrument. Our initial hypothesis is that phonetics are user- and instrument-dependent, but they remain constant for a single subject and instrument. We propose a user-adapted system, where mappings from voice features to synthesis parameters depend on how subjects sing musical articulations, i.e. note to note transitions. The system consists of two components. First, a voice signal segmentation module that automatically determines note-to-note transitions. Second, a classifier that determines the type of musical articulation for each transition based on a set of phonetic features. For validating our hypothesis, we run an experiment where subjects imitated real instrument recordings with their voice. Performance recordings consisted of short phrases of saxophone and violin performed in three grades of musical articulation labeled as: staccato, normal, legato. The results of a supervised training classifier (user-dependent) are compared to a classifier based on heuristic rules (user-independent). Finally, from the previous results we show how to control the articulation in a sample-concatenation synthesizer by selecting the most appropriate samples.

  14. A Review of Training Opportunities for Singing Voice Rehabilitation Specialists.

    Training opportunities for singing voice rehabilitation specialists are growing and changing. This is happening despite a lack of agreed-on guidelines or an accredited certification acknowledged by the governing bodies in the fields of speech-language pathology and vocal pedagogy, the American Speech-Language Hearing Association and the National Association of Teachers of Singing, respectively. The roles of the speech-language pathologist, the singing teacher, and the person who bridges this gap, the singing voice rehabilitation specialist, are now becoming better defined and more common among the voice care community. To that end, this article aims to review the current opportunities for training in the field of singing voice rehabilitation. A review of available university training programs, private training programs and mentorships, clinical fellowships, professional organizations, conferences, vocal training across genres, and self-study opportunities was conducted. All institutional listings are with permission from program leaders. Although many avenues are available for training of singing voice rehabilitation specialists, there is no accredited comprehensive training program at this point. This review gathers information on current training opportunities from across various modalities. The listings are not intended to be comprehensive but rather representative of possibilities for interested practitioners. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

    2007-09-01

    This paper proposes a 3D multimedia presentation tool that allows the user to manipulate intuitively only through the voice input and the gesture input without using a standard keyboard or a mouse device. The authors developed this system as a presentation tool to be used in a presentation room equipped a large screen like an exhibition room in a museum because, in such a presentation environment, it is better to use voice commands and the gesture pointing input rather than using a keyboard or a mouse device. This system was developed using IntelligentBox, which is a component-based 3D graphics software development system. IntelligentBox has already provided various types of 3D visible, reactive functional components called boxes, e.g., a voice input component and various multimedia handling components. IntelligentBox also provides a dynamic data linkage mechanism called slot-connection that allows the user to develop 3D graphics applications by combining already existing boxes through direct manipulations on a computer screen. Using IntelligentBox, the 3D multimedia presentation tool proposed in this paper was also developed as combined components only through direct manipulations on a computer screen. The authors have already proposed a 3D multimedia presentation tool using a stage metaphor and its voice input interface. This time, we extended the system to make it accept the user gesture input besides voice commands. This paper explains details of the proposed 3D multimedia presentation tool and especially describes its component-based voice and gesture input interfaces.

    Environmental and/or work risk factors, lack of basic knowledge related to voice, its incorrect use, and a defective vocal model can lead teachers to develop occupational dysphonia. This study aimed to analyze studies focusing on occupational vocal disorders through a literature review. Articles published over a period of 11 years in periodicals indexed in the ScieLO library were searched according to predetermined inclusion and exclusion criteria. Twenty articles related to teachers' vocal occupational disorders were found. We argue that intense vocal use should not harm professionals; the voice has to be pleasant to the speaker and correctly produced. The conclusion is that there is a scarcity of articles available at the studied library relating to teachers' voice disorders. Further studies need to be developed and disseminated so as to increase knowledge in the subject.

    2009-07-01

    Full Text Available Although the Internet has received significant attention in recent years, voice is still the most convenient and natural way of communicating between human to human or human to computer. In voice applications, users may have different needs which will require the ability of the system to reason, make decisions, be flexible and adapt to requests during interaction. These needs have placed new requirements in voice application development such as use of advanced models, techniques and methodologies which take into account the needs of different users and environments. The ability of a system to behave close to human reasoning is often mentioned as one of the major requirements for the development of voice applications. In this paper, we present a framework for an intelligent voice-enabled e-Education application and an adaptation of the framework for the development of a prototype Course Registration and Examination (CourseRegExamOnline module. This study is a preliminary report of an ongoing e-Education project containing the following modules: enrollment, course registration and examination, enquiries/information, messaging/collaboration, e-Learning and library. The CourseRegExamOnline module was developed using VoiceXML for the voice user interface(VUI, PHP for the web user interface (WUI, Apache as the middle-ware and MySQL database as back-end. The system would offer dual access modes using the VUI and WUI. The framework would serve as a reference model for developing voice-based e-Education applications. The e-Education system when fully developed would meet the needs of students who are normal users and those with certain forms of disabilities such as visual impairment, repetitive strain injury (RSI, etc, that make reading and writing difficult.

  13. Start/End Delays of Voiced and Unvoiced Speech Signals

    Energy Technology Data Exchange (ETDEWEB)

    Herrnstein, A

    1999-09-24

    Recent experiments using low power EM-radar like sensors (e.g, GEMs) have demonstrated a new method for measuring vocal fold activity and the onset times of voiced speech, as vocal fold contact begins to take place. Similarly the end time of a voiced speech segment can be measured. Secondly it appears that in most normal uses of American English speech, unvoiced-speech segments directly precede or directly follow voiced-speech segments. For many applications, it is useful to know typical duration times of these unvoiced speech segments. A corpus, assembled earlier of spoken ''Timit'' words, phrases, and sentences and recorded using simultaneously measured acoustic and EM-sensor glottal signals, from 16 male speakers, was used for this study. By inspecting the onset (or end) of unvoiced speech, using the acoustic signal, and the onset (or end) of voiced speech using the EM sensor signal, the average duration times for unvoiced segments preceding onset of vocalization were found to be 300ms, and for following segments, 500ms. An unvoiced speech period is then defined in time, first by using the onset of the EM-sensed glottal signal, as the onset-time marker for the voiced speech segment and end marker for the unvoiced segment. Then, by subtracting 300ms from the onset time mark of voicing, the unvoiced speech segment start time is found. Similarly, the times for a following unvoiced speech segment can be found. While data of this nature have proven to be useful for work in our laboratory, a great deal of additional work remains to validate such data for use with general populations of users. These procedures have been useful for applying optimal processing algorithms over time segments of unvoiced, voiced, and non-speech acoustic signals. For example, these data appear to be of use in speaker validation, in vocoding, and in denoising algorithms.

    2017-01-01

    The aging of the voice, known as presbyphonia, is a natural process that can cause great change in vocal quality of the individual. This is a relevant problem to those people who use their voices professionally, and its early identification can help determine a suitable treatment to avoid its progress or even to eliminate the problem. This work focuses on the development of a new model for the identification of aging voices (independently of their chronological age), using as input attributes parameters extracted from the voice and glottal signals. The proposed model, named Quantum binary-real evolving Spiking Neural Network (QbrSNN), is based on spiking neural networks (SNNs), with an unsupervised training algorithm, and a Quantum-Inspired Evolutionary Algorithm that automatically determines the most relevant attributes and the optimal parameters that configure the SNN. The QbrSNN model was evaluated in a database composed of 120 records, containing samples from three groups of speakers. The results obtained indicate that the proposed model provides better accuracy than other approaches, with fewer input attributes. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    You need a compelling reason to implement voice recognition technology. At my institution, the compelling reason was a turnaround time for Radiology results of more than two days. Only 41 percent of our reports were transcribed and signed within 24 hours. In November 1998, a team from Lehigh Valley Hospital went to RSNA and reviewed every voice system on the market. The evaluation was done with the radiologist workflow in mind, and we came back from the meeting with the vendor selection completed. The next steps included developing a business plan, approval of funds, reference calls to more than 15 sites and contract negotiation, all of which took about six months. The department of Radiology at Lehigh Valley Hospital and Health Network (LVHHN) is a multi-site center that performs over 360,000 procedures annually. The department handles all modalities of radiology: general diagnosis, neuroradiology, ultrasound, CT Scan, MRI, interventional radiology, arthography, myelography, bone densitometry, nuclear medicine, PET imaging, vascular lab and other advanced procedures. The department consists of 200 FTEs and a medical staff of more than 40 radiologists. The budget is in the $10.3 million range. There are three hospital sites and four outpatient imaging center sites where services are provided. At Lehigh Valley Hospital, radiologists are not dedicated to one subspecialty, so implementing a voice system by modality was not an option. Because transcription was so far behind, we needed to eliminate that part of the process. As a result, we decided to deploy the system all at once and with the radiologists as editors. The planning and testing phase took about four months, and the implementation took two weeks. We deployed over 40 workstations and trained close to 50 physicians. The radiologists brought in an extra radiologist from our group for the two weeks of training. That allowed us to train without taking a radiologist out of the department. We trained three to six

    To determine whether perceptual adaptation improves voice gender discrimination of spectrally shifted vowels and, if so, which acoustic cues contribute to the improvement. Voice gender discrimination was measured for 10 normal-hearing subjects, during 5 days of adaptation to spectrally shifted vowels, produced by processing the speech of 5 male and 5 female talkers with 16-channel sine-wave vocoders. The subjects were randomly divided into 2 groups; one subjected to 50-Hz, and the other to 200-Hz, temporal envelope cutoff frequencies. No preview or feedback was provided. There was significant adaptation in voice gender discrimination with the 200-Hz cutoff frequency, but significant improvement was observed only for 3 female talkers with F(0) > 180 Hz and 3 male talkers with F(0) gender discrimination under spectral shift conditions with perceptual adaptation, but spectral shift may limit the exclusive use of spectral information and/or the use of formant structure on voice gender discrimination. The results have implications for cochlear implant users and for understanding voice gender discrimination.

    To determine the anatomical and physiological nature of voice problems and their treatment in those group fitness instructors (GFIs) who have sought a medical diagnosis; the impact of voice disorders on quality of life and their contribution to activity limitations and participation restrictions; and the perceived attitudes and level of support from the industry at large in response to instructor's voice disorders and need for treatment. Prospective self-completion questionnaire design. Thirty-eight individuals (3 males and 35 females) currently active in the Australian fitness industry who had been diagnosed with a voice disorder completed an online self-completion questionnaire administered via SurveyMonkey. Laryngeal pathology included vocal fold nodules (N = 24), vocal fold cysts (N = 2), vocal fold hemorrhage (N = 1), and recurrent chronic laryngitis (N = 3). Eight individuals reported vocal strain and muscle tension dysphonia without concurrent vocal fold pathology. Treatment methods were variable, with 73.68% (N = 28) receiving voice therapy alone, 7.89% (N = 3) having voice therapy in combination with surgery, and 10.53% (N = 4) having voice therapy in conjunction with medication. Three individuals (7.89%) received no treatment for their voice disorder. During treatment, 82% of the cohort altered their teaching practices. Half of the cohort reported that their voice problems led to social withdrawal, decreased job satisfaction, and emotional distress. Greater than 65% also reported being dissatisfied with the level of industry and coworker support during the period of voice recovery. This study identifies that GFIs are susceptible to a number of voice disorders that impact their social and professional lives, and there is a need for more proactive training and advice on voice care for instructors, as well as those in management positions within the industry to address mixed approaches and opinions regarding the importance of voice care.

    The military detection assessment laboratory houses an experimental field system which assesses different alarm indicators such as fence disturbance sensors, MILES cables, and microwave Racons. A speech synthesis board which could be interfaced, by means of a computer, to an alarm logger making verbal acknowledgement of alarms possible was purchased. Different products and different types of voice synthesis were analyzed before a linear predictive code device produced by Telesensory Speech Systems of Palo Alto, California was chosen. This device is called the Speech 1000 Board and has a dedicated 8085 processor. A multiplexer card was designed and the Sp 1000 interfaced through the card into a TMS 990/100M Texas Instrument microcomputer. It was also necessary to design the software with the capability of recognizing and flagging an alarm on any 1 of 32 possible lines. The experimental field system was then packaged with a dc power supply, LED indicators, speakers, and switches, and deployed in the field performing reliably.

  2. How to help teachers' voices.

    Science.gov (United States)

    Saatweber, Margarete

    2008-01-01

    It has been shown that teachers are at high risk of developing occupational dysphonia, and it has been widely accepted that the vocal characteristics of a speaker play an important role in determining the reactions of listeners. The functions of breathing, breathing movement, breathing tonus, voice vibrations and articulation tonus are transmitted to the listener. So we may conclude that listening to the teacher's voice at school influences children's behavior and the perception of spoken language. This paper presents the concept of Schlaffhorst-Andersen including exercises to help teachers improve their voice, breathing, movement and their posture. Copyright 2008 S. Karger AG, Basel.

    Voice Stress Analysis (VSA) systems are marketed as computer-based systems capable of measuring stress in a person's voice as an indicator of deception. They are advertised as being less expensive, easier to use, less invasive in use, and less constrained in their operation then polygraph technology. The National Institute of Justice have asked the Air Force Research Laboratory for assistance in evaluating voice stress analysis technology. Law enforcement officials have also been asking questions about this technology. If VSA technology proves to be effective, its value for military and law enforcement application is tremendous.

    Listeners often describe the voices of solo child singers as being "pure" or "clear"; these terms would suggest that the voice is not only pleasant but also clearly audible. The audibility or clarity could be attributed to the presence of high-frequency partials in the sound: a "brightness" or "ring." This article aims to investigate spectrally the acoustic nature of this ring phenomenon in children's solo voices, and in particular, relating it to their "nonring" production. Additionally, this is set in the context of establishing to what extent, if any, the spectral characteristics of ring are shared with those of the singer's formant cluster associated with professional adult opera singers in the 2.5-3.5kHz region. A group of child solo singers, acknowledged as outstanding by a singing teacher who specializes in teaching professional child singers, were recorded in a major UK concert hall performing Come unto him, all ye that labour, from the aria He shall feed his flock from The Messiah by GF Handel. Their singing was accompanied by a recording of a piano played through in-ear headphones. Sound pressure recordings were made from well within the critical distance in the hall. The singers were observed to produce notes with and without ring, and these recordings were analyzed in the frequency domain to investigate their spectra. The results indicate that there is evidence to suggest that ring in child solo singers is carried in two areas of the output spectrum: first in the singer's formant cluster region, centered around 4kHz, which is more than 1000Hz higher than what is observed in adults; and second in the region around 7.5-11kHz where a significant strengthening of harmonic presence is observed. A perceptual test has been carried out demonstrating that 94% of 62 listeners label a synthesized version of the calculated overall average ring spectrum for all subjects as having ring when compared with a synthesized version of the calculated overall average nonring

    Full Text Available Purpose. Since human voice characteristics are specific to each individual, numerous anthropological studies have been oriented to find significant relationships between voice and morpho-functional features. The goal of this study was to identify the correlation between seven morpho-functional variables and six voice acoustic parameters in sportsmen. Methods. Following the protocols of the International Biological Program, seven morpho-functional variables and six voice acoustic parameters have been measured in 88 male professional athletes from Kosovo, aged 17-35 years, during the period of April-October 2013. The statistical analysis was accomplished through the SPSS program, version 20. The obtained data were analysed through descriptive parameters and with Spearman’s method of correlation analysis. Results. Spearman’s method of correlation showed significant negative correlations (R = -0.215 to -0.613; p = 0.05 between three voice acoustic variables of the fundamental frequency of the voice sample (Mean, Minimum, and Maximum Pitch and six morpho-functional measures (Body Height, Body Weight, Margaria-Kalamen Power Test, Sargent Jump Test, Pull-up Test, and VO2max.abs. Conclusions. The significant correlations imply that the people with higher stature have longer vocal cords and a lower voice. These results encourage investigations on predicting sportsmen’s functional abilities on the basis of their voice acoustic parameters.

    Doctor-patient interaction (DPI) includes different voices, of which the educator voice is of considerable importance. Physicians employ this voice to educate patients and their caregivers by providing them with information in order to change the patients' behavior and improve their health status. The subject has not yet been fully understood, and therefore the present study was conducted to explore the pattern of educator voice. For this purpose, conversation analysis (CA) of 33 recorded clinical consultations was performed in outpatient educational clinics in Shiraz, Iran between April 2014 and September 2014. In this qualitative study, all utterances, repetitions, lexical forms, chuckles and speech particles were considered and interpreted as social actions. Interpretations were based on inductive data-driven analysis with the aim to find recurring patterns of educator voice. The results showed educator voice to have two general features: descriptive and prescriptive. However, the pattern of educator voice comprised characteristics such as superficiality, marginalization of patients, one-dimensional approach, ignoring a healthy lifestyle, and robotic nature. The findings of this study clearly demonstrated a deficiency in the educator voice and inadequacy in patient-centered dialogue. In this setting, the educator voice was related to a distortion of DPI through the physicians' dominance, leading them to ignore their professional obligation to educate patients. Therefore, policies in this regard should take more account of enriching the educator voice through training medical students and faculty members in communication skills.

    The purpose of this study is to analyze the vocal behavior of flamenco singers, as compared with classical music singers, to establish a differential vocal profile of voice habits and behaviors in flamenco music. Bibliographic review was conducted, and the Singer's Vocal Habits Questionnaire, an experimental tool designed by the authors to gather data regarding hygiene behavior, drinking and smoking habits, type of practice, voice care, and symptomatology perceived in both the singing and the speaking voice, was administered. We interviewed 94 singers, divided into two groups: the flamenco experimental group (FEG, n = 48) and the classical control group (CCG, n = 46). Frequency analysis, a Likert scale, and discriminant and exploratory factor analysis were used to obtain a differential profile for each group. The FEG scored higher than the CCG in speaking voice symptomatology. The FEG scored significantly higher than the CCG in use of "inadequate vocal technique" when singing. Regarding voice habits, the FEG scored higher in "lack of practice and warm-up" and "environmental habits." A total of 92.6% of the subjects classified themselves correctly in each group. The Singer's Vocal Habits Questionnaire has proven effective in differentiating flamenco and classical singers. Flamenco singers are exposed to numerous vocal risk factors that make them more prone to vocal fatigue, mucosa dehydration, phonotrauma, and muscle stiffness than classical singers. Further research is needed in voice training in flamenco music, as a means to strengthen the voice and enable it to meet the requirements of this musical genre. Copyright © 2017 The Voice Foundation.

    McMullan, E; Gupta, A; Collins, S C

    2018-04-01

    WHAT IS KNOWN ON THE SUBJECT?: Community mental health staff and their service users have reported mixed views on the importance of talking about the content of voices. Community staff have reported feeling that they do not have the skills to explore voice content and worry about making things worse. Voice hearers experiencing extreme distress due to the content of their voices can access support through acute inpatient mental health services. No previous studies have focused on the experiences of staff who nurse voice hearers at a time of acute distress. WHAT DOES THIS STUDY ADD TO EXISTING KNOWLEDGE?: MHNs and HSWs working with voice hearers in acute distress report feeling powerless and helpless, as they feel that they cannot lessen the distress experienced by the voice hearer. Despite these difficult feelings, staff report finding ways of coping, including using structured tools to help make sense of their service users' voice-hearing experiences and accessing reflective practice forums. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Due to the current context of increased acuity and limited resources in acute services, there may be a need to further protect time for staff to access reflective practice groups and supervision forums to help them manage the difficult feelings arising from their work with voice hearers. Introduction Mental health nursing (MHN) staff in acute settings work with voice hearers at times of crises when they experience high levels of distress. Previous research has focused on community mental health staff's experiences and their service users views on exploring the content of voices. No studies have explored this from an acute mental health service perspective. Aim This study therefore sought to explore the experiences of staff working with voice hearers in an acute mental health service. Method Due to the exploratory nature of the research, a qualitative design was chosen. Three MHNs and five healthcare support workers (HSWs) were

    The Rehabilitation Engineering Research Center on Technology Evaluation and Transfer is exploring how the users of assistive technology devices define the ideal device. This work is called the Consumer Ideal Product program. The results show what device characteristics are most and least important, indicating where to place the priority on product features and functions from the consumer's perspective. The "voice of the customer" can be used (1) to define the ideal characteristics of a product, (2) to make trade-offs in product design and function improvements based on their relative importance to the consumer, (3) to compare the characteristics of existing products against the characteristics of the ideal product, or (4) to generate a product checklist for consumers to use when making a purchase decision. This paper presents the results of consumers' defining the ideal battery charger. Four focus groups generated the survey's content, then 100 experienced users rated 159 characteristics organized under 11 general evaluation criteria. The consumers placed the highest importance on characteristics from the general evaluation criteria of product reliability, effectiveness, and physical security/safety. The findings should help manufacturers and vendors improve their products and services and help professionals and consumers make informed choices.

    When education for nurses became a reality, leaders in the emerging profession spoke out early and often for educational improvements to prepare those who would nurse. The writings and speeches of Isabel Hampton Robb, Mary Adelaide Nutting, Lavinia Lloyd Dock, Lillian Wald, and Isabel Maitland Stewart formed the basis for a qualitative study that documents the voices of early nursing leaders who contributed to the development of nursing education as it moved from "training" toward professional education in a university setting. What is documented in the literature is the desire of these women to enhance the professional status of nursing through improvements in its educational system.

    2013-05-01

    This study was designed as a qualitative case study to demonstrate the process of diagnosis and treatment between a voice team to manage a singer diagnosed with muscular tension dysphonia (MTD). Traditionally, literature suggests that MTD is challenging to treat and little in the literature directly addresses singers with MTD. Data collected included initial medical screening with laryngologist, referral to speech-language pathologist (SLP) specializing in voice disorders among singers, and adjunctive voice training with voice teacher trained in vocology (singing voice specialist or SVS). Initial target goals with SLP included reducing extrinsic laryngeal tension, using a relaxed laryngeal posture, and effective abdominal-diaphragmatic support for all phonation events. Balance of respiratory forces, laryngeal coordination, and use of optimum filtering of the source signal through resonance and articulatory awareness was emphasized. Further work with SVS included three main goals including a lowered breathing pattern to aid in decreasing subglottic air pressure, vertical laryngeal position to lower to allow for a relaxed laryngeal position, and a top-down singing approach to encourage an easier, more balanced registration, and better resonance. Initial results also emphasize the retraining of subject toward a sensory rather than auditory mode of monitoring. Other areas of consideration include singers' training and vocal use, the psychological effects of MTD, the personalities potentially associated with it, and its relationship with stress. Finally, the results emphasize that a positive rapport with the subject and collaboration between all professionals involved in a singer's care are essential for recovery.

    In common with individuals experiencing a number of disorders, people with anorexia nervosa report experiencing an internal 'voice'. The anorexic voice comments on the individual's eating, weight and shape and instructs the individual to restrict or compensate. However, the core characteristics of the anorexic voice are not known. This study aimed to develop a parsimonious model of the voice characteristics that are related to key features of eating disorder pathology and to determine whether patients with anorexia nervosa fall into groups with different voice experiences. The participants were 49 women with full diagnoses of anorexia nervosa. Each completed validated measures of the power and nature of their voice experience and of their responses to the voice. Different voice characteristics were associated with current body mass index, duration of disorder and eating cognitions. Two subgroups emerged, with 'weaker' and 'stronger' voice experiences. Those with stronger voices were characterized by having more negative eating attitudes, more severe compensatory behaviours, a longer duration of illness and a greater likelihood of having the binge-purge subtype of anorexia nervosa. The findings indicate that the anorexic voice is an important element of the psychopathology of anorexia nervosa. Addressing the anorexic voice might be helpful in enhancing outcomes of treatments for anorexia nervosa, but that conclusion might apply only to patients with more severe eating psychopathology. Copyright © 2016 John Wiley & Sons, Ltd. Experiences of an internal 'anorexic voice' are common in anorexia nervosa. Clinicians should consider the role of the voice when formulating eating pathology in anorexia nervosa, including how individuals perceive and relate to that voice. Addressing the voice may be beneficial, particularly in more severe and enduring forms of anorexia nervosa. When working with the voice, clinicians should aim to address both the content of the voice and how

  20. Anti-voice adaptation suggests prototype-based coding of voice identity

    Directory of Open Access Journals (Sweden)

    Marianne eLatinus

    2011-07-01

    Full Text Available We used perceptual aftereffects induced by adaptation with anti-voice stimuli to investigate voice identity representations. Participants learned a set of voices then were tested on a voice identification task with vowel stimuli morphed between identities, after different conditions of adaptation. In Experiment 1, participants chose the identity opposite to the adapting anti-voice significantly more often than the other two identities (e.g., after being adapted to anti-A, they identified the average voice as A. In Experiment 2, participants showed a bias for identities opposite to the adaptor specifically for anti-voice, but not for non anti-voice adaptors. These results are strikingly similar to adaptation aftereffects observed for facial identity. They are compatible with a representation of individual voice identities in a multidimensional perceptual voice space referenced on a voice prototype.

    Rajput, Sudheesh K; Matoba, Osamu

    2017-11-15

    We propose an optical voice encryption scheme based on digital holography (DH). An off-axis DH is employed to acquire voice information by obtaining phase retardation occurring in the object wave due to sound wave propagation. The acquired hologram, including voice information, is encrypted using optical image encryption. The DH reconstruction and decryption with all the correct parameters can retrieve an original voice. The scheme has the capability to record the human voice in holograms and encrypt it directly. These aspects make the scheme suitable for other security applications and help to use the voice as a potential security tool. We present experimental and some part of simulation results.

  2. Patients as team members: opportunities, challenges and paradoxes of including patients in multi-professional healthcare teams.

    Martin, Graham P; Finn, Rachael

    2011-11-01

    Current healthcare policy emphasises the need for more collaborative, team-based approaches to providing care, and for a greater voice for service users in the management and delivery of care. Increasingly, policy encourages 'partnerships' between users and professionals so that users, too, effectively become team members. In examining this phenomenon, this paper draws on insights from the organisational-sociological literature on team work, which highlights the challenges of bringing together diverse professional groups, but which has not, to date, been applied in contexts where users, too, are included in teams. Using data from a qualitative study of five pilot cancer-genetics projects, in which service users were included in teams responsible for managing and developing new services, it highlights the difficulties involved in making teams of such heterogeneous members-and the paradoxes that arise when this task is achieved. It reveals how the tension between integration and specialisation of team members, highlighted in the literature on teams in general, is especially acute for service users, the distinctiveness of whose contribution is more fragile, and open to blurring. © 2011 The Authors.

    As the primary means of communication, voice plays an important role in daily life. Voice also conveys personal information such as social status, personal traits, and the emotional state of the speaker. Mechanically, voice production involves complex fluid-structure interaction within the glottis and its control by laryngeal muscle activation. An important goal of voice research is to establish a causal theory linking voice physiology and biomechanics to how speakers use and control voice to communicate meaning and personal information. Establishing such a causal theory has important implications for clinical voice management, voice training, and many speech technology applications. This paper provides a review of voice physiology and biomechanics, the physics of vocal fold vibration and sound production, and laryngeal muscular control of the fundamental frequency of voice, vocal intensity, and voice quality. Current efforts to develop mechanical and computational models of voice production are also critically reviewed. Finally, issues and future challenges in developing a causal theory of voice production and perception are discussed.

    Service user involvement in all levels of healthcare provision is the expectation of UK government policy. Involvement should not only include participation in the planning and delivery of health care but also the exercise of choice and opinions about that care. In practice, however, service user engagement is most often tokenistic, involving post hoc consultation over plans already committed to by services. This paper explores an Occupational Therapy-led initiative to use the Serious Game format to engage low secure service users with serious mental illness in the design, layout and refurbishment of their unit. Among other things how medication was to be dispensed on the new unit was explored by this game and led to significant replanning in response to service user involvement. The game format was found to be a useful tool in facilitating communication between professionals and a traditionally marginalized and powerless client group. It enabled service users to have a voice, it provided a format for that voice to be heard and made possible service-led change in the planning process. © 2010 Blackwell Publishing.

    The study analyzed health professionals' conceptions toward female users of crack and powder cocaine currently receiving psychosocial care, based on a gender perspective. Seventeen health professionals were interviewed, and systematic observations were made of the spaces for collective care in a Center for Psychosocial Care specializing in alcohol and drug addiction in Greater Metropolitan Rio de Janeiro, Brazil. Analysis of the interviews and field diaries using the hermeneutic-dialectic method revealed three categories: frailty as a constitutive attribute of women's condition, the women's emotional addiction to crack and powder cocaine use, and gender stereotypes during psychosocial care. The health professionals voiced a traditional view of the heterosexual, docile, and maternal woman and reproduced stereotypical concepts when addressing female crack and cocaine users as sensitive, frail individuals, emotionally dependent on men and more involved in the home and family. These professionals need a more refined understanding of gender issues in the mental health-disease process in order to allow overcoming preconceived notions and reductionist health care practices.

    Full Text Available Background. Teachers as voice professionals with heavy vocal load represent a population at high risk of vocal problems. Until now there has not been any study evaluating prevalence and risk factors for voice disorders among teachers in Slovenia.Methods. Questionnaires about voice disorders and vocal habits were sent to randomly chosen 10% of elementary, middle schools and kindergarten in Slovenia. Answers from 1509 completed questionnaires were analyzed by statistical program SPSS 11.0.Results. In the school year 2002/03 51% of teachers occasionally experienced voice disorders and 15% did frequently. The prevalence of transient voice problems was therefore about 66%. By univariate χ 2 test we found statistically significant relationship to frequent voice disorders for female sex (p < 0.02, middle school teachers (p < 0.02, age over 40 years (p < 0.0005 and atopic constitution (p < 0.006; voice disorders during study showed borderline significance (p < 0.07. There was no significant relationship to voice problems for yelling, talking loudly or rapidly, using chalk while talking, cigarette smoking, water intake and gastroesophageal reflux. Statistically significant variates were included in the multivariate logistic regression model. There was 1.9-times higher risk of experiencing frequent voice disorders in females than for males (p < 0.003. Risk of vocal problems in middle school teachers was 1.5-times higher than in kindergarten teachers (p < 0.01 and 1.8-times higher than in elementary school teachers (p < 0.0005. Age over 40 years carried 2,3-times higher risk for hoarseness than age under 40 years (p < 0.0005. Voice disorders during study showed 1.7-times higher risk for later occupational vocal problems (p < 0.02. Atopic constitution had 1.6-times higher risk for frequent vocal problems (p < 0.008. The questionaire also showed how unfamiliar to vocal hygiene Slovene teachers are.Conclusions. The prevalence of voice disorders among

    Many common voice disorders are chronic or recurring conditions that are likely to result from faulty and/or abusive patterns of vocal behavior, referred to generically as vocal hyperfunction. An ongoing goal in clinical voice assessment is the development and use of noninvasively derived measures to quantify and track the daily status of vocal hyperfunction so that the diagnosis and treatment of such behaviorally based voice disorders can be improved. This paper reports on the development of a new, versatile, and cost-effective clinical tool for mobile voice monitoring that acquires the high-bandwidth signal from an accelerometer sensor placed on the neck skin above the collarbone. Using a smartphone as the data acquisition platform, the prototype device provides a user-friendly interface for voice use monitoring, daily sensor calibration, and periodic alert capabilities. Pilot data are reported from three vocally normal speakers and three subjects with voice disorders to demonstrate the potential of the device to yield standard measures of fundamental frequency and sound pressure level and model-based glottal airflow properties. The smartphone-based platform enables future clinical studies for the identification of the best set of measures for differentiating between normal and hyperfunctional patterns of voice use.

  14. English Voicing in Dimensional Theory*

    Science.gov (United States)

    Iverson, Gregory K.; Ahn, Sang-Cheol

    2007-01-01

    Assuming a framework of privative features, this paper interprets two apparently disparate phenomena in English phonology as structurally related: the lexically specific voicing of fricatives in plural nouns like wives or thieves and the prosodically governed “flapping” of medial /t/ (and /d/) in North American varieties, which we claim is itself not a rule per se, but rather a consequence of the laryngeal weakening of fortis /t/ in interaction with speech-rate determined segmental abbreviation. Taking as our point of departure the Dimensional Theory of laryngeal representation developed by Avery & Idsardi (2001), along with their assumption that English marks voiceless obstruents but not voiced ones (Iverson & Salmons 1995), we find that an unexpected connection between fricative voicing and coronal flapping emerges from the interplay of familiar phonemic and phonetic factors in the phonological system.

    In this research, we investigated the effects of voice and face information on the perceptual learning of talkers and on long-term memory for spoken words. In the first phase, listeners were trained over several days to identify voices from words presented auditorily or audiovisually. The training data showed that visual information about speakers enhanced voice learning, revealing cross-modal connections in talker processing akin to those observed in speech processing. In the second phase, the listeners completed an auditory or audiovisual word recognition memory test in which equal numbers of words were spoken by familiar and unfamiliar talkers. The data showed that words presented by familiar talkers were more likely to be retrieved from episodic memory, regardless of modality. Together, these findings provide new information about the representational code underlying familiar talker recognition and the role of stimulus familiarity in episodic word recognition.

Or as the young boy in Jules Verne’s Journey to the Centre of the Earth calls back to his distant-voiced companions: ‘Lost… in the most intense darkness.’ ‘Then I understood it,’ says the boy, Axel, ‘To make them hear me, all I had to do was to speak with my mouth close to the wall, which would serve to conduct my voice, as the wire conducts the electric fluid’ (Verne 1864. By timing their calls, the group of explorers work out that Axel is separated from them by a distance of four miles, held in a cavernous vertical gallery of smooth rock. Feeling his way down towards the others, the boy ends up falling, along with his voice, through the space. Losing consciousness he seems to give himself up to the space...

    Speech recognition (SR) systems such as Siri or Google Now have become an increasingly popular human-computer interaction method, and have turned various systems into voice controllable systems(VCS). Prior work on attacking VCS shows that the hidden voice commands that are incomprehensible to people can control the systems. Hidden voice commands, though hidden, are nonetheless audible. In this work, we design a completely inaudible attack, DolphinAttack, that modulates voice commands on ultra...

  18. Speaker's voice as a memory cue.

    Campeanu, Sandra; Craik, Fergus I M; Alain, Claude

    2015-02-01

    Speaker's voice occupies a central role as the cornerstone of auditory social interaction. Here, we review the evidence suggesting that speaker's voice constitutes an integral context cue in auditory memory. Investigation into the nature of voice representation as a memory cue is essential to understanding auditory memory and the neural correlates which underlie it. Evidence from behavioral and electrophysiological studies suggest that while specific voice reinstatement (i.e., same speaker) often appears to facilitate word memory even without attention to voice at study, the presence of a partial benefit of similar voices between study and test is less clear. In terms of explicit memory experiments utilizing unfamiliar voices, encoding methods appear to play a pivotal role. Voice congruency effects have been found when voice is specifically attended at study (i.e., when relatively shallow, perceptual encoding takes place). These behavioral findings coincide with neural indices of memory performance such as the parietal old/new recollection effect and the late right frontal effect. The former distinguishes between correctly identified old words and correctly identified new words, and reflects voice congruency only when voice is attended at study. Characterization of the latter likely depends upon voice memory, rather than word memory. There is also evidence to suggest that voice effects can be found in implicit memory paradigms. However, the presence of voice effects appears to depend greatly on the task employed. Using a word identification task, perceptual similarity between study and test conditions is, like for explicit memory tests, crucial. In addition, the type of noise employed appears to have a differential effect. While voice effects have been observed when white noise is used at both study and test, using multi-talker babble does not confer the same results. In terms of neuroimaging research modulations, characterization of an implicit memory effect

  20. I like my voice better: self-enhancement bias in perceptions of voice attractiveness.

    Science.gov (United States)

    Hughes, Susan M; Harrison, Marissa A

    2013-01-01

    Previous research shows that the human voice can communicate a wealth of nonsemantic information; preferences for voices can predict health, fertility, and genetic quality of the speaker, and people often use voice attractiveness, in particular, to make these assessments of others. But it is not known what we think of the attractiveness of our own voices as others hear them. In this study eighty men and women rated the attractiveness of an array of voice recordings of different individuals and were not told that their own recorded voices were included in the presentation. Results showed that participants rated their own voices as sounding more attractive than others had rated their voices, and participants also rated their own voices as sounding more attractive than they had rated the voices of others. These findings suggest that people may engage in vocal implicit egotism, a form of self-enhancement.

    Poor voice quality due to a voice disorder can lead to a reduced quality of life. In occupations where voice use is substantial it can lead to periods of absence from work. To evaluate the effectiveness of interventions to prevent voice disorders in adults. We searched MEDLINE (PubMed, 1950 to 2006), EMBASE (1974 to 2006), CENTRAL (The Cochrane Library, Issue 2 2006), CINAHL (1983 to 2006), PsychINFO (1967 to 2006), Science Citation Index (1986 to 2006) and the Occupational Health databases OSH-ROM (to 2006). The date of the last search was 05/04/06. Randomised controlled clinical trials (RCTs) of interventions evaluating the effectiveness of treatments to prevent voice disorders in adults. For work-directed interventions interrupted time series and prospective cohort studies were also eligible. Two authors independently extracted data and assessed trial quality. Meta-analysis was performed where appropriate. We identified two randomised controlled trials including a total of 53 participants in intervention groups and 43 controls. One study was conducted with teachers and the other with student teachers. Both trials were poor quality. Interventions were grouped into 1) direct voice training, 2) indirect voice training and 3) direct and indirect voice training combined.1) Direct voice training: One study did not find a significant decrease of the Voice Handicap Index for direct voice training compared to no intervention.2) Indirect voice training: One study did not find a significant decrease of the Voice Handicap Index for indirect voice training when compared to no intervention.3) Direct and indirect voice training combined: One study did not find a decrease of the Voice Handicap Index for direct and indirect voice training combined when compared to no intervention. The same study did however find an improvement in maximum phonation time (Mean Difference -3.18 sec; 95 % CI -4.43 to -1.93) for direct and indirect voice training combined when compared to no

    To assess aspects related to work, stress and quality of life related to voice in soccer coaches (C) and physical trainers (T), comparing the categories. Qualitative and quantitative studies with 13 C and 13 T of teams competing in Phase One of the highest level (Série A ) of the 2012 Campeonato Paulista (São Paulo State Soccer Championship). The questions were open ended and related to complaints, difficulties, and/or problems regarding voice use during work and to the relations between voice, work, stress, and quality of life. Stress at work was analyzed by the Job Stress Scale (JSS) questionnaire. The perception of the impact of the voice on quality of life was evaluated by the Voice-Related Quality of Life (V-RQOL) protocol. The answers to the questions were transcribed and submitted to content analysis, and regarding the questionnaire, descriptive data and analytical statistics were used. Content analysis showed lack of preparation for voice care; voice complaints; and intense vocal use demand under stressful work, in addition to the absence of healthy habits and social/family support. The JSS dimensions showed that the Active Work situation and the high V-RQOL scores are compatible with vocal health without complaints. There were no statistical differences between the categories. Both categories reported complaints/problems linked to professional voice use and stressful workload. However, the perception of vocal impact on the quality of life was positive, and the analysis of stress at work resulted in "good" and favorable conditions. The relationship between voice, work, stress, and quality of life in both the categories require further investigations.

    Full Text Available Objectives: To characterize the objective voice parameters among school workers, and to identi­fy associated factors of three objective voice parameters, namely fundamental frequency, sound pressure level and maximum phonation time. Materials and methods: We conducted a cross-sectional study among 116 Colombian teachers and 20 Colombian non-teachers. After signing the informed consent form, participants filled out a questionnaire. Then, a voice sample was recorded and evaluated perceptually by a speech therapist and by objective voice analysis with praat software. Short-term environmental measurements of sound level, temperature, humi­dity, and reverberation time were conducted during visits at the workplaces, such as classrooms and offices. Linear regression analysis was used to determine associations between individual and work-related factors and objective voice parameters. Results: Compared with men, women had higher fundamental frequency (201 Hz for teachers and 209 for non-teachers vs. 120 Hz for teachers and 127 for non-teachers and sound pressure level (82 dB vs. 80 dB, and shorter maximum phonation time (around 14 seconds vs. around 16 seconds. Female teachers younger than 50 years of age evidenced a significant tendency to speak with lower fundamental frequen­cy and shorter mpt compared with female teachers older than 50 years of age. Female teachers had significantly higher fundamental frequency (66 Hz, higher sound pressure level (2 dB and short phonation time (2 seconds than male teachers. Conclusion: Female teachers younger than 50 years of age had significantly lower F0 and shorter mpt compared with those older than 50 years of age. The multivariate analysis showed that gender was a much more important determinant of variations in F0, spl and mpt than age and teaching occupation. Objectively measured temperature also contributed to the changes on spl among school workers.

However, voice disorders also present with other symptoms such as difficulty in maintaining the voice (asthenia, vocal fatigue, variation in habitual vocal fundamental frequency, hoarseness, lack of vocal volume and projection, loss of vocal efficiency, and weakness when speaking. There are several proposals for the etiologic classification of dysphonia: functional, organofunctional, organic, and work-related voice disorder (WRVD.OBJECTIVE: To conduct a literature review on WRVD and on the current Brazilian labor legislation.METHODS: This was a review article with bibliographical research conducted on the PubMed and Bireme databases, using the terms "work-related voice disorder", "occupational dysphonia", "dysphonia and labor legislation", and a review of labor and social security relevant laws.CONCLUSION: WRVD is a situation that frequently is listed as a reason for work absenteeism, functional rehabilitation, or for prolonged absence from work. Currently, forensic physicians have no comparative parameters to help with the analysis of vocal disorders. In certain situations WRVD may cause, work disability. This disorder may be labor-related, or be an adjuvant factor to work-related diseases.

    Full Text Available Introduction: Voice disorders are a well-known complication which is often associated with thyroid gland diseases and because voice is still the basic mean of communication it is very important to maintain its quality healthy. Objectives: The aim of this study referred to questions whether there is a statistically significant difference between results of voice self-assessment, perceptual voice assessment and acoustic voice analysis before and after thyroidectomy and whether there are statistically significant correlations between variables of voice self-assessment, perceptual assessment and acoustic analysis before and after thyroidectomy. Methods: This scientific research included 12 participants aged between 41 and 76. Voice self-assessment was conducted with the help of Croatian version of Voice Handicap Index (VHI. Recorded reading samples were used for perceptual assessment and later evaluated by two clinical speech and language therapists. Recorded samples of phonation were used for acoustic analysis which was conducted with the help of acoustic program Praat. All of the data was processed through descriptive statistics and nonparametric statistical methods. Results: Results showed that there are statistically significant differences between results of voice self-assessments and results of acoustic analysis before and after thyroidectomy. Statistically significant correlations were found between variables of perceptual assessment and acoustic analysis. Conclusion: Obtained results indicate the importance of multidimensional, preoperative and postoperative assessment. This kind of assessment allows the clinician to describe all of the voice features and provides appropriate recommendation for further rehabilitation to the patient in order to optimize voice outcomes.

    The advent of microprocessors and other large-scale integration (LSI) circuits is making voice input and output for computers and instruments practical; specialized LSI chips for speech processing are appearing on the market. Voice can be used to input data or to issue instrument commands; this allows the operator to engage in other tasks, move about, and to use standard data entry systems. Voice synthesizers can generate audible, easily understood instructions. Using voice characteristics, a control system can verify speaker identity for security purposes. Two simple voice-controlled systems have been designed at Los Alamos for nuclear safeguards applicaations. Each can easily be expanded as time allows. The first system is for instrument control that accepts voice commands and issues audible operator prompts. The second system is for access control. The speaker's voice is used to verify his identity and to actuate external devices

    To analyze the communication resources reported by managers in the business environment and compare the resources used to those reported by business professionals. 82 professionals volunteered to participate in the research, divided into 50 managers (MP) and 32 business professionals (BP) from industry section in Caxias do Sul and the surrounding region (Brazil). A questionnaire with 4 topics was used: personal data, self-assessment of communicative behavior, self-assessment of communicative resources, and selection of positive and negative resources influencing communication. Regarding communicative behavior, both groups reported normal voice but with significant differences regarding the use of softness in communication, 25% of MP and only 4% of BP. Both groups selected the following main positive resources: knowledge of subject, use of proper vocabulary, and objectivity. The negative resources were, similarly, the lack of subject domain, criticism or prejudgment, and improper vocabulary. Finally, analyzing the degree of influence of each communicative resource, the MP highlighted tone of voice as an important positive resource, while the BP pointed the subject domain. Still, the monotonous voice for MP and nervousness for BP were indicated as the main negative influences. Managers value more communicative resources connected to communicative attitude, such as tone of voice and expression, while business professionals worry about demonstrating security and technical understanding of the subject.

    1998-04-01

    During the war in Bosnia-Herzegovina (BIH), the infrastructure of the health care system was destroyed and health officials, health care providers, and women experienced the war from their own perspectives. Using the principles of continuous quality improvement (CQI), these perspectives were honored and served as the basis for an international training program to hear the voices of women in war and the concerns of those who cared for them. With the results of a comprehensive national survey of all partners, the World Health Organization's European Regional Office held a five-day workshop that used CQI methods. The facilitators and 18 nurses, midwives, and physicians from six cantons developed interventions to address the women's needs, as detailed from the women's stories and from the professional perspectives of governmental authorities and health providers. The effort illustrates the ways in which the principles and tools of CQI can be used to capture the needs of the users of the services with those responsible for restructuring the health service and those with overall responsibility for the health of woman throughout the country.

    2014-05-01

    The American musical theatre industry is a multibillion dollar business in which the requirements for singers are varied and complex. This study identifies the musical genres and voice requirements that are currently most requested at professional auditions to help voice teachers, pedagogues, and physicians who work with musical theatre singers understand the demands of their clients' business. Frequency count. One thousand two thirty-eight professional musical theatre audition listings were gathered over a 6-month period, and information from each listing was categorized and entered into a spreadsheet for analysis. The results indicate that four main genres of music were requested over a wide variety of styles, with more than half of auditions requesting genre categories that may not be served by traditional or classical voice technique alone. To adequately prepare young musical theatre performers for the current job market and keep the performers healthily making the sounds required by the industry, new singing styles may need to be studied and integrated into voice training that only teaches classical styles.

    2005-10-01

    To examine whether prenatal exposure to music and voice alters foetal behaviour and whether foetal response to music differs from human voice. A prospective observational study was conducted in 20 normal term pregnant mothers. Ten foetuses were exposed to music and voice for 15 s at different sound pressure levels to find out the optimal setting for the auditory stimulation. Music, voice and sham were played to another 10 foetuses via a headphone on the maternal abdomen. The sound pressure level was 105 db and 94 db for music and voice, respectively. Computerised assessment of foetal heart rate and activity were recorded. 90 actocardiograms were obtained for the whole group. One way anova followed by posthoc (Student-Newman-Keuls method) analysis was used to find if there is significant difference in foetal response to music and voice versus sham. Foetuses responded with heart rate acceleration and motor response to both music and voice. This was statistically significant compared to sham. There was no significant difference between the foetal heart rate acceleration to music and voice. Prenatal exposure to music and voice alters the foetal behaviour. No difference was detected in foetal response to music and voice.

    The technology of transmitting voice over data networks has been available for over 10 years. Mass market VoIP services for consumers to make and receive standard telephone calls over broadband Internet networks have grown in the last 5 years. While operational costs are less with VoIP implementations as opposed to time division multiplexing (TDM) based voice switches, is it still advantageous to convert a mission control center s voice system to this newer technology? Marshall Space Flight Center (MSFC) Huntsville Operations Support Center (HOSC) has converted its mission voice services to a commercial product that utilizes VoIP technology. Results from this testing, design, and installation have shown unique considerations that must be addressed before user operations. There are many factors to consider for a control center voice design. Technology advantages and disadvantages were investigated as they refer to cost. There were integration concerns which could lead to complex failure scenarios but simpler integration for the mission infrastructure. MSFC HOSC will benefit from this voice conversion with less product replacement cost, less operations cost and a more integrated mission services environment.

    Current mechanical key in the motorcycle is prone to bulgary, being stolen or misplaced. Intelligent biometric voice recognition as means to replace this mechanism is proposed as an alternative. The proposed system will decide whether the voice is belong to the user or not and the word utter by the user is ‘On’ or ‘Off’. The decision voice will be sent to Arduino in order to start or stop the engine. The recorded voice is processed in order to get some features which later be used as input to the proposed system. The Mel-Frequency Ceptral Coefficient (MFCC) is adopted as a feature extraction technique. The extracted feature is the used as input to the SVM-based identifier. Experimental results confirm the effectiveness of the proposed intelligent voice recognition and word recognition system. It show that the proposed method produces a good training and testing accuracy, 99.31% and 99.43%, respectively. Moreover, the proposed system shows the performance of false rejection rate (FRR) and false acceptance rate (FAR) accuracy of 0.18% and 17.58%, respectively. In the intelligent word recognition shows that the training and testing accuracy are 100% and 96.3%, respectively.

    Ana Cristina Nunes Ruas

    Full Text Available INTRODUCTION: Leishmaniasis is considered as one of the six most important infectious diseases because of its high detection coefficient and ability to produce deformities. In most cases, mucosal leishmaniasis (ML occurs as a consequence of cutaneous leishmaniasis. If left untreated, mucosal lesions can leave sequelae, interfering in the swallowing, breathing, voice and speech processes and requiring rehabilitation. OBJECTIVE: To describe the anatomical characteristics and voice quality of ML patients. MATERIALS AND METHODS: A descriptive transversal study was conducted in a cohort of ML patients treated at the Laboratory for Leishmaniasis Surveillance of the Evandro Chagas National Institute of Infectious Diseases-Fiocruz, between 2010 and 2013. The patients were submitted to otorhinolaryngologic clinical examination by endoscopy of the upper airways and digestive tract and to speech-language assessment through directed anamnesis, auditory perception, phonation times and vocal acoustic analysis. The variables of interest were epidemiologic (sex and age and clinic (lesion location, associated symptoms and voice quality. RESULTS: 26 patients under ML treatment and monitored by speech therapists were studied. 21 (81% were male and five (19% female, with ages ranging from 15 to 78 years (54.5+15.0 years. The lesions were distributed in the following structures 88.5% nasal, 38.5% oral, 34.6% pharyngeal and 19.2% laryngeal, with some patients presenting lesions in more than one anatomic site. The main complaint was nasal obstruction (73.1%, followed by dysphonia (38.5%, odynophagia (30.8% and dysphagia (26.9%. 23 patients (84.6% presented voice quality perturbations. Dysphonia was significantly associated to lesions in the larynx, pharynx and oral cavity. CONCLUSION: We observed that vocal quality perturbations are frequent in patients with mucosal leishmaniasis, even without laryngeal lesions; they are probably associated to disorders of some

  13. Voice congruency facilitates word recognition.

    Full Text Available Behavioral studies of spoken word memory have shown that context congruency facilitates both word and source recognition, though the level at which context exerts its influence remains equivocal. We measured event-related potentials (ERPs while participants performed both types of recognition task with words spoken in four voices. Two voice parameters (i.e., gender and accent varied between speakers, with the possibility that none, one or two of these parameters was congruent between study and test. Results indicated that reinstating the study voice at test facilitated both word and source recognition, compared to similar or no context congruency at test. Behavioral effects were paralleled by two ERP modulations. First, in the word recognition test, the left parietal old/new effect showed a positive deflection reflective of context congruency between study and test words. Namely, the same speaker condition provided the most positive deflection of all correctly identified old words. In the source recognition test, a right frontal positivity was found for the same speaker condition compared to the different speaker conditions, regardless of response success. Taken together, the results of this study suggest that the benefit of context congruency is reflected behaviorally and in ERP modulations traditionally associated with recognition memory.

    Laryngovideostroboscopy is the method most frequently used in the assessment of voice disorders. However, the employment of quantitative methods, such as voice acoustic analysis, is essential for evaluating the effectiveness of prophylactic and therapeutic activities as well as for objective medical certification of larynx pathologies. The aim of this study was to examine voice acoustic parameters in female teachers with occupational voice diseases. Acoustic analysis (IRIS software) was performed in 66 female teachers, including 35 teachers with occupational voice diseases and 31 with functional dysphonia. The teachers with occupational voice diseases presented the lower average fundamental frequency (193 Hz) compared to the group with functional dysphonia (209 Hz) and to the normative value (236 Hz), whereas other acoustic parameters did not differ significantly in both groups. Voice acoustic analysis, when applied separately from vocal loading, cannot be used as a testing method to verify the diagnosis of occupational voice disorders.

    Full Text Available Objective: Voice onset time is known to be cue for the distinction between voiced and voiceless stops and it can be used to describe or categorize a range of developmental, neuromotor and linguistic disorders. The aim of this study is determination of standard values of voice onset time for Azerbaijani language (Tabriz dialect. Materials & Methods: In this description-analytical study, 30 Azeris persons whom were selected conveniently by simple selection, uttered 46 monosyllabic words initiating with 6 Azerbaijani stops twice. Using Praat software, the voice onset time values were analyzed by waveform and wideband spectrogram in milliseconds. Vowel effect, sex differences and the effect of place of articulation on VOT, were evaluated and data were analyzed by one-way ANOVA test. Results: There was no significant difference in voice onset time between male and female Azeris speakers (P<0.05. Vowel and place of articulation had significant correlation with voice onset time (P<0.001. Voice onset time values for /b/, /p/, /d/, /t/, /g/, /k/, and [c], [ɟ] allophones were 10.64, 86.88, 13.35, 87.09, 26.25, 100.62, 131.19, 63.18 mili second, respectively. Conclusion: Voice onset time values are the same for Azerbaijani men and women. However, like many other languages, back and high vowels and back place of articulation lengthen VOT. Also, voiceless stops are aspirated in this language and voiced stops have positive VOT values.

  18. Singing Voice Analysis, Synthesis, and Modeling

    Science.gov (United States)

    Kim, Youngmoo E.

    The singing voice is the oldest musical instrument, but its versatility and emotional power are unmatched. Through the combination of music, lyrics, and expression, the voice is able to affect us in ways that no other instrument can. The fact that vocal music is prevalent in almost all cultures is indicative of its innate appeal to the human aesthetic. Singing also permeates most genres of music, attesting to the wide range of sounds the human voice is capable of producing. As listeners we are naturally drawn to the sound of the human voice, and, when present, it immediately becomes the focus of our attention.

    Full Text Available The ability to recognize an individual from their voice is a widespread ability with a long evolutionary history. Yet, the perceptual representation of familiar voices is ill-defined. In two experiments, we explored the neuropsychological processes involved in the perception of voice identity. We specifically explored the hypothesis that familiar voices (trained-to-familiar (Experiment 1, and famous voices (Experiment 2 are represented as a whole complex pattern, well approximated by the average of multiple utterances produced by a single speaker. In experiment 1, participants learned three voices over several sessions, and performed a three-alternative forced-choice identification task on original voice samples and several “speaker averages,” created by morphing across varying numbers of different vowels (e.g., [a] and [i] produced by the same speaker. In experiment 2, the same participants performed the same task on voice samples produced by familiar speakers. The two experiments showed that for famous voices, but not for trained-to-familiar voices, identification performance increased and response times decreased as a function of the number of utterances in the averages. This study sheds light on the perceptual representation of familiar voices, and demonstrates the power of average in recognizing familiar voices. The speaker average captures the unique characteristics of a speaker, and thus retains the information essential for recognition; it acts as a prototype of the speaker.

    2014-01-01

    Carnatic singing is a classical South Indian style of music that involves rigorous training to produce an "open throated" loud, predominantly low-pitched singing, embedded with vocal nuances in higher pitches. Voice problems in singers are not uncommon. The objective was to report the nature of voice problems and apply a routine protocol to assess the voice. Forty-five trained performing singers (females: 36 and males: 9) who reported to a tertiary care hospital with voice problems underwent voice assessment. The study analyzed their problems and the clinical findings. Voice change, difficulty in singing higher pitches, and voice fatigue were major complaints. Most of the singers suffered laryngopharyngeal reflux that coexisted with muscle tension dysphonia and chronic laryngitis. Speaking voices were rated predominantly as "moderate deviation" on GRBAS (Grade, Rough, Breathy, Asthenia, and Strain). Maximum phonation time ranged from 4 to 29 seconds (females: 10.2, standard deviation [SD]: 5.28 and males: 15.7, SD: 5.79). Singing frequency range was reduced (females: 21.3 Semitones and males: 23.99 Semitones). Dysphonia severity index (DSI) scores ranged from -3.5 to 4.91 (females: 0.075 and males: 0.64). Singing frequency range and DSI did not show significant difference between sex and across clinical diagnosis. Self-perception using voice disorder outcome profile revealed overall severity score of 5.1 (SD: 2.7). Findings are discussed from a clinical intervention perspective. Study highlighted the nature of voice problems (hyperfunctional) and required modifications in assessment protocol for Carnatic singers. Need for regular assessments and vocal hygiene education to maintain good vocal health are emphasized as outcomes. Copyright © 2014 The Voice Foundation. Published by Mosby, Inc.

    The Transsexual Voice Questionnaire (TVQ MtF ) was designed to capture the voice-related perceptions of individuals whose gender identity as female is the opposite of their birth-assigned gender (MtF women). Evaluation of the psychometric properties of the TVQ MtF is ongoing. To investigate associations between TVQ MtF scores and (1) self-perceptions of voice femininity and (2) acoustic parameters of voice pitch and voice quality in order to evaluate further the validity of the TVQ MtF . A strong correlation between TVQ MtF scores and self-ratings of voice femininity was predicted, but no association between TVQ MtF scores and acoustic measures of voice pitch and quality was proposed. Participants were 148 MtF women (mean age 48.14 years) recruited from the La Trobe Communication Clinic and the clinics of three doctors specializing in transgender health. All participants completed the TVQ MtF and 34 of these participants also provided a voice sample for acoustic analysis. Pearson product-moment correlation analysis was conducted to examine the associations between TVQ MtF scores and (1) self-perceptions of voice femininity and (2) acoustic measures of F0, jitter (%), shimmer (dB) and harmonic-to-noise ratio (HNR). Strong negative correlations between the participants' perceptions of their voice femininity and the TVQ MtF scores demonstrated that for this group of MtF women a low self-rating of voice femininity was associated with more frequent negative voice-related experiences. This association was strongest with the vocal-functioning component of the TVQ MtF . These strong correlations and high levels of shared variance between the TVQ MtF and a measure of a related construct provides evidence for the convergent validity of the TVQ MtF . The absence of significant correlations between the TVQ MtF and the acoustic data is consistent with the equivocal findings of earlier research. This finding indicates that these two measures assess different aspects of the voice

    Full Text Available The ‘temporal voice areas’ (TVAs (Belin et al., 2000 of the human brain show greater neuronal activity in response to human voices than to other categories of nonvocal sounds. However, a direct link between TVA activity and voice perceptionbehaviour has not yet been established. Here we show that a functional magnetic resonance imaging (fMRI measure of activity in the TVAs predicts individual performance at a separately administered voice memory test. This relation holds whengeneral sound memory ability is taken into account. These findings provide the first evidence that the TVAs are specifically involved in voice cognition.

    Voice disorders affect adults and children and have different causes in different age groups. The aim of the study is to present the etiology and diagnosis dysphonia in a large population of patients with this voice disorder.for dysphonia of a large population of dysphonic patients. We evaluated 2019 patients with dysphonia who attended the Voice Disease ambulatories of a university hospital. Parameters assessed were age, gender, profession, associated symptoms, smoking, and videolaryngoscopy diagnoses. Of the 2019 patients with dysphonia who were included in this study, 786 were male (38.93%) and 1233 were female (61.07). The age groups were as follows: 1-6 years (n = 100); 7-12 years (n = 187); 13-18 years (n = 92); 19-39 years (n = 494); 41-60 years (n = 811); and >60 years (n = 335). Symptoms associated with dysphonia were vocal overuse (n = 677), gastroesophageal symptoms (n = 535), and nasosinusal symptoms (n = 497). The predominant professions of the patients were domestic workers, students, and teachers. Smoking was reported by 13.6% patients. With regard to the etiology of dysphonia, in children (1-18 years old), nodules (n = 225; 59.3%), cysts (n = 39; 10.3%), and acute laryngitis (n = 26; 6.8%) prevailed. In adults (19-60 years old), functional dysphonia (n = 268; 20.5%), acid laryngitis (n = 164; 12.5%), and vocal polyps (n = 156; 12%) predominated. In patients older than 60 years, presbyphonia (n = 89; 26.5%), functional dysphonia (n = 59; 17.6%), and Reinke's edema (n = 48; 14%) predominated. In this population of 2019 patients with dysphonia, adults and women were predominant. Dysphonia had different etiologies in the age groups studied. Nodules and cysts were predominant in children, functional dysphonia and reflux in adults, and presbyphonia and Reinke's edema in the elderly. Copyright © 2016 The Voice Foundation.

    The aim of this study was to investigate the relationship between extrinsic laryngeal muscular hypertonicity and deviant body posture on the one hand and voice handicap and voice quality on the other hand in teachers with persistent voice complaints and a history of voice-related absenteeism. The study group consisted of 25 female teachers. A voice therapist assessed extrinsic laryngeal muscular tension and a physical therapist assessed body posture. The assessed parameters were clustered in categories. The parameters in the different categories represent the same function. Further a tension/posture index was created, which is the summation of the different parameters. The different parameters and the index were related to the Voice Handicap Index (VHI) and the Dysphonia Severity Index (DSI). The scores of the VHI and the individual parameters differ significantly except for the posterior weight bearing and tension of the sternocleidomastoid muscle. There was also a significant difference between the individual parameters and the DSI, except for tension of the cricothyroid muscle and posterior weight bearing. The score of the tension/posture index correlates significantly with both the VHI and the DSI. In a linear regression analysis, the combination of hypertonicity of the sternocleidomastoid, the geniohyoid muscles and posterior weight bearing is the most important predictor for a high voice handicap. The combination of hypertonicity of the geniohyoid muscle, posterior weight bearing, high position of the hyoid bone, hypertonicity of the cricothyroid muscle and anteroposition of the head is the most important predictor for a low DSI score. The results of this study show the higher the score of the index, the higher the score of the voice handicap and the worse the voice quality is. Moreover, the results are indicative for the importance of assessment of muscular tension and body posture in the diagnosis of voice disorders.

    Examine the relationship among the severity of patient-perceived voice impairment, perceptual dysphonia severity, occupational voice demand, and voice therapy adherence. Identify clinical predictors of increased risk for therapy nonadherence. A retrospective cohort study of patients presenting with a chief complaint of persistent dysphonia at an interdisciplinary voice center was done. The Voice Handicap Index-10 (VHI-10) and the Voice-Related Quality of Life (V-RQOL) survey scores, clinician rating of dysphonia severity using the Grade score from the Grade, Roughness Breathiness, Asthenia, and Strain scale, occupational voice demand, and patient demographics were tested for associations with therapy adherence, defined as completion of the treatment plan. Classification and Regression Tree (CART) analysis was performed to establish thresholds for nonadherence risk. Of 166 patients evaluated, 111 were recommended for voice therapy. The therapy nonadherence rate was 56%. Occupational voice demand category, VHI-10, and V-RQOL scores were the only factors significantly correlated with therapy adherence (P demand are significantly more likely to be nonadherent with therapy than those with high occupational voice demand (P 40 is a significant cutoff point for predicting therapy nonadherence (P demand and patient perception of impairment are significantly and independently correlated with therapy adherence. A VHI-10 score of ≤9 or a V-RQOL score of >40 is a significant cutoff point for predicting nonadherence risk. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Most previous studies of vocal attractiveness have focused on preferences for physical characteristics of voices such as pitch. Here we examine the content of vocalizations in interaction with such physical traits, finding that vocal cues of social interest modulate the strength of men's preferences for raised pitch in women's voices. Men showed stronger preferences for raised pitch when judging the voices of women who appeared interested in the listener than when judging the voices of women who appeared relatively disinterested in the listener. These findings show that voice preferences are not determined solely by physical properties of voices and that men integrate information about voice pitch and the degree of social interest expressed by women when forming voice preferences. Women's preferences for raised pitch in women's voices were not modulated by cues of social interest, suggesting that the integration of cues of social interest and voice pitch when men judge the attractiveness of women's voices may reflect adaptations that promote efficient allocation of men's mating effort.

    The aim of this study was to investigate alterations in voice parameters among patients using continuous positive airway pressure (CPAP) for the treatment of obstructive sleep apnea syndrome. Patients with an indication for CPAP treatment without any voice problems and with normal laryngeal findings were included and voice parameters were evaluated before and 1 and 6 months after CPAP. Videolaryngostroboscopic findings, a self-rated scale (Voice Handicap Index-10, VHI-10), perceptual voice quality assessment (GRBAS: grade, roughness, breathiness, asthenia, strain), and acoustic parameters were compared. Data from 70 subjects (48 men and 22 women) with a mean age of 44.2 ± 6.0 years were evaluated. When compared with the pre-CPAP treatment period, there was a significant increase in the VHI-10 score after 1 month of treatment and in VHI- 10 and total GRBAS scores, jitter percent (P = 0.01), shimmer percent, noise-to-harmonic ratio, and voice turbulence index after 6 months of treatment. Vague negative effects on voice parameters after the first month of CPAP treatment became more evident after 6 months. We demonstrated nonsevere alterations in the voice quality of patients under CPAP treatment. Given that CPAP is a long-term treatment it is important to keep these alterations in mind.

    2016-12-01

    The final keynote panel of the 10th Pan-European Voice Conference (PEVOC) was concerned with the topic 'Voice pedagogy-what do we need?' In this communication the panel discussion is summarized, and the authors provide a deepening discussion on one of the key questions, addressing the roles and tasks of people working with voice students. In particular, a distinction is made between (1) voice building (derived from the German term 'Stimmbildung'), primarily comprising the functional and physiological aspects of singing; (2) coaching, mostly concerned with performance skills; and (3) singing voice rehabilitation. Both public and private educators are encouraged to apply this distinction to their curricula, in order to arrive at more efficient singing teaching and to reduce the risk of vocal injury to the singers concerned.

    The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization. In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    2012-12-01

    VoiceThread has been utilized in an undergraduate research methods course for peer review and final research project dissemination. VoiceThread (http://www.voicethread.com) can be considered a social media tool, as it is a web-based technology with the capacity to enable interactive dialogue. VoiceThread is an application that allows a user to place a media collection online containing images, audio, videos, documents, and/or presentations in an interface that facilitates asynchronous communication. Participants in a VoiceThread can be passive viewers of the online content or engaged commenters via text, audio, video, with slide annotations via a doodle tool. The VoiceThread, which runs across browsers and operating systems, can be public or private for viewing and commenting and can be embedded into any website. Although few university students are aware of the VoiceThread platform (only 10% of the students surveyed by Ng (2012)), the 2009 K-12 edition of The Horizon Report (Johnson et al., 2009) lists VoiceThread as a tool to watch because of the opportunities it provides as a collaborative learning environment. In Fall 2011, eleven students enrolled in an undergraduate research methods course at Penn State Brandywine each conducted their own small-scale research project. Upon conclusion of the projects, students were required to create a poster summarizing their work for peer review. To facilitate the peer review process outside of class, each student-created PowerPoint file was placed in a VoiceThread with private access to only the class members and instructor. Each student was assigned to peer review five different student posters (i.e., VoiceThread images) with the audio and doodle tools to comment on formatting, clarity of content, etc. After the peer reviews were complete, the students were allowed to edit their PowerPoint poster files for a new VoiceThread. In the new VoiceThread, students were required to video record themselves describing their research

  9. Your Cheatin' Voice Will Tell on You: Detection of Past Infidelity from Voice.

    Hughes, Susan M; Harrison, Marissa A

    2017-01-01

    Evidence suggests that many physical, behavioral, and trait qualities can be detected solely from the sound of a person's voice, irrespective of the semantic information conveyed through speech. This study examined whether raters could accurately assess the likelihood that a person has cheated on committed, romantic partners simply by hearing the speaker's voice. Independent raters heard voice samples of individuals who self-reported that they either cheated or had never cheated on their romantic partners. To control for aspects that may clue a listener to the speaker's mate value, we used voice samples that did not differ between these groups for voice attractiveness, age, voice pitch, and other acoustic measures. We found that participants indeed rated the voices of those who had a history of cheating as more likely to cheat. Male speakers were given higher ratings for cheating, while female raters were more likely to ascribe the likelihood to cheat to speakers. Additionally, we manipulated the pitch of the voice samples, and for both sexes, the lower pitched versions were consistently rated to be from those who were more likely to have cheated. Regardless of the pitch manipulation, speakers were able to assess actual history of infidelity; the one exception was that men's accuracy decreased when judging women whose voices were lowered. These findings expand upon the idea that the human voice may be of value as a cheater detection tool and very thin slices of vocal information are all that is needed to make certain assessments about others.

  10. A pneumatic Bionic Voice prosthesis-Pre-clinical trials of controlling the voice onset and offset.

    Full Text Available Despite emergent progress in many fields of bionics, a functional Bionic Voice prosthesis for laryngectomy patients (larynx amputees has not yet been achieved, leading to a lifetime of vocal disability for these patients. This study introduces a novel framework of Pneumatic Bionic Voice Prostheses as an electronic adaptation of the Pneumatic Artificial Larynx (PAL device. The PAL is a non-invasive mechanical voice source, driven exclusively by respiration with an exceptionally high voice quality, comparable to the existing gold standard of Tracheoesophageal (TE voice prosthesis. Following PAL design closely as the reference, Pneumatic Bionic Voice Prostheses seem to have a strong potential to substitute the existing gold standard by generating a similar voice quality while remaining non-invasive and non-surgical. This paper designs the first Pneumatic Bionic Voice prosthesis and evaluates its onset and offset control against the PAL device through pre-clinical trials on one laryngectomy patient. The evaluation on a database of more than five hours of continuous/isolated speech recordings shows a close match between the onset/offset control of the Pneumatic Bionic Voice and the PAL with an accuracy of 98.45 ±0.54%. When implemented in real-time, the Pneumatic Bionic Voice prosthesis controller has an average onset/offset delay of 10 milliseconds compared to the PAL. Hence it addresses a major disadvantage of previous electronic voice prostheses, including myoelectric Bionic Voice, in meeting the short time-frames of controlling the onset/offset of the voice in continuous speech.

    Developing compassion towards oneself has been linked to improvement in many areas of psychological well-being, including psychosis. Furthermore, developing a non-judgemental, accepting way of relating to voices is associated with lower levels of distress for people who hear voices. These factors have also been associated with secure attachment. This study explores associations between the constructs of mindfulness of voices, self-compassion, and distress from hearing voices and how secure attachment style related to each of these variables. Cross-sectional online. One hundred and twenty-eight people (73% female; M age  = 37.5; 87.5% Caucasian) who currently hear voices completed the Self-Compassion Scale, Southampton Mindfulness of Voices Questionnaire, Relationships Questionnaire, and Hamilton Programme for Schizophrenia Voices Questionnaire. Results showed that mindfulness of voices mediated the relationship between self-compassion and severity of voices, and self-compassion mediated the relationship between mindfulness of voices and severity of voices. Self-compassion and mindfulness of voices were significantly positively correlated with each other and negatively correlated with distress and severity of voices. Mindful relation to voices and self-compassion are associated with reduced distress and severity of voices, which supports the proposed potential benefits of mindful relating to voices and self-compassion as therapeutic skills for people experiencing distress by voice hearing. Greater self-compassion and mindfulness of voices were significantly associated with less distress from voices. These findings support theory underlining compassionate mind training. Mindfulness of voices mediated the relationship between self-compassion and distress from voices, indicating a synergistic relationship between the constructs. Although the current findings do not give a direction of causation, consideration is given to the potential impact of mindful and

  14. Suggestions for Layout and Functional Behavior of Software-Based Voice Switch Keysets

    Scott, David W.

    2010-01-01

    Marshall Space Flight Center (MSFC) provides communication services for a number of real time environments, including Space Shuttle Propulsion support and International Space Station (ISS) payload operations. In such settings, control team members speak with each other via multiple voice circuits or loops. Each loop has a particular purpose and constituency, and users are assigned listen and/or talk capabilities for a given loop based on their role in fulfilling the purpose. A voice switch is a given facility's hardware and software that supports such communication, and may be interconnected with other facilities switches to create a large network that, from an end user perspective, acts like a single system. Since users typically monitor and/or respond to several voice loops concurrently for hours on end and real time operations can be very dynamic and intense, it s vital that a control panel or keyset for interfacing with the voice switch be a servant that reduces stress, not a master that adds it. Implementing the visual interface on a computer screen provides tremendous flexibility and configurability, but there s a very real risk of overcomplication. (Remember how office automation made life easier, which led to a deluge of documents that made life harder?) This paper a) discusses some basic human factors considerations related to keysets implemented as application software windows, b) suggests what to standardize at the facility level and what to leave to the user's preference, and c) provides screen shot mockups for a robust but reasonably simple user experience. Concepts apply to keyset needs in almost any type of operations control or support center.

    To analyze the performance of a phonatory deviation diagram (PDD) in discriminating the presence and severity of voice deviation and the predominant voice quality of synthesized voices. A speech-language pathologist performed the auditory-perceptual analysis of the synthesized voice (n = 871). The PDD distribution of voice signals was analyzed according to area, quadrant, shape, and density. Differences in signal distribution regarding the PDD area and quadrant were detected when differentiating the signals with and without voice deviation and with different predominant voice quality. Differences in signal distribution were found in all PDD parameters as a function of the severity of voice disorder. The PDD area and quadrant can differentiate normal voices from deviant synthesized voices. There are differences in signal distribution in PDD area and quadrant as a function of the severity of voice disorder and the predominant voice quality. However, the PDD area and quadrant do not differentiate the signals as a function of severity of voice disorder and differentiated only the breathy and rough voices from the normal and strained voices. PDD density is able to differentiate only signals with moderate and severe deviation. PDD shape shows differences between signals with different severities of voice deviation. © 2018 S.

    The aim of the study was to evaluate the rationale for training in voice emission and voice prophylaxis among teachers and to assess the effects of voice disorders rehabilitation in the selected group of teachers participating in the program "Protect your voice." An anonymous survey was conducted among 463 teachers participating in the training part of the program. The effectivness of rehabilitation of teachers with occupational voice disorders was evaluated among 51 subjects (average age: 43 years) taking part in diagnostic and rehabilitation part of the program. Phonation voice exercises with speech therapist and physiotherapy (iontophoresis, inhalations and elektrostimulation) were administered. Evaluation of rehabilitation was based on phoniatric examination, including videostroboscopy and statistical calculations. The survey showed that among teachers there is high demand (98%) for training in proper voice emission, hygiene and prevention of voice. The effectiveness of rehabilitation has been confirmed by the observed improvements in phonatory activities of larynx, proper breathing during phonation (p = 0.0000), the voice quality (p = 0.0022), prolonged phonation time (an average of 1.39 s), increased number of people who correctly activated resonators (p = 0.0000) and increased number of people with phonation without excesive muscle tension of the neck. The results indicate that among all the professionally active teachers, there is a need for regular training of proper voice emission and vocal hygiene and then conduct individually phonation and breathing exercises, supported by the physiotherapy. This should be an effective method of voice disorders prevention in teachers. Med Pr 2017;68(5):593-603. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    2017-07-01

    Researchers have described the difficulties of doing abortion work, including the psychosocial costs to individual providers. Some have discussed the self-censorship in which providers engage in to protect themselves and the pro-choice movement. However, few have examined the costs of this self-censorship to public discourse and social movements in the US. Using qualitative data collected during abortion providers' discussions of their work, we explore the tensions between their narratives and pro-choice discourse, and examine the types of stories that are routinely silenced - narratives we name "dangertalk". Using these data, we theorize about the ways in which giving voice to these tensions might transform current abortion discourse by disrupting false dichotomies and better reflecting the complex realities of abortion. We present a conceptual model for dangertalk in abortion discourse, connecting it to functions of dangertalk in social movements more broadly. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Mediatization: a concept, multiple voices

    2016-12-01

    Full Text Available Mediatization has become increasingly a key concept, fundamental, essential to describe the present and the history of media and communicative change taking place. Thus, it became part of a whole, one can not see them as a separate sphere. In this perspective, the media coverage is used as a concept to describe the process of expansion of the different technical means and consider the interrelationships between the communicative change, means and sociocultural change. However, although many researchers use the concept of mediatization, each gives you the meaning that best suits your needs. Thus, the concept of media coverage is treated with multiple voices. This paper discusses this problem and present a preliminary pre-position on the matter.

    1994-10-01

    This paper describes an automated method of comparing a voice sample of an unknown individual with samples from known speakers in order to establish or verify the individual's identity. The method is based on a statistical pattern matching approach that employs a simple training procedure, requires no human intervention (transcription, work or phonetic marketing, etc.), and makes no assumptions regarding the expected form of the statistical distributions of the observations. The content of the speech material (vocabulary, grammar, etc.) is not assumed to be constrained in any way. An algorithm is described which incorporates frame pruning and channel equalization processes designed to achieve robust performance with reasonable computational resources. An experimental implementation demonstrating the feasibility of the concept is described.

    The rise of research and advocacy over the years to establish a disability voice in Australia with regard to bioethical issues is explored. This includes an analysis of some of the political processes and engagement in mainstream bioethical debate. An understanding of the politics of rejected knowledge is vital in understanding the muted disability voices in Australian bioethics and public policy. It is also suggested that the voices of those who are marginalised or oppressed in society, such as people with disability, have particular contribution to make in fostering critical bioethics.

    Full Text Available This study addressed the effect of misleading post-event information (PEI on voice ratings, identification accuracy, and confidence, as well as the link between verbal recall and accuracy. Participants listened to a dialogue between male and female targets, then read misleading information about voice pitch. Participants engaged in verbal recall, rated voices on a feature checklist, and made a lineup decision. Accuracy rates were low, especially on target-absent lineups. Confidence and accuracy were unrelated, but the number of facts recalled about the voice predicted later lineup accuracy. There was a main effect of misinformation on ratings of target voice pitch, but there was no effect on identification accuracy or confidence ratings. As voice lineup evidence from earwitnesses is used in courts, the findings have potential applied relevance.

    Purpose The purpose of this paper is to describe the use of group concept mapping (GCM) as a tool for developing a conceptual model of an episode of acute, unscheduled care from illness or injury to outcomes such as recovery, death and chronic illness. Design/methodology/approach After generating a literature review drafting an initial conceptual model, GCM software (CS Global MAX TM ) is used to organize and identify strengths and directionality between concepts generated through feedback about the model from several stakeholder groups: acute care and non-acute care providers, patients, payers and policymakers. Through online and in-person population-specific focus groups, the GCM approach seeks feedback, assigned relationships and articulated priorities from participants to produce an output map that described overarching concepts and relationships within and across subsamples. Findings A clustered concept map made up of relational data points that produced a taxonomy of feedback was used to update the model for use in soliciting additional feedback from two technical expert panels (TEPs), and finally, a public comment exercise was performed. The results were a stakeholder-informed improved model for an acute care episode, identified factors that influence process and outcomes, and policy recommendations, which were delivered to the Department of Health and Human Services's (DHHS) Assistant Secretary for Preparedness and Response. Practical implications This study provides an example of the value of cross-population multi-stakeholder input to increase voice in shared problem health stakeholder groups. Originality/value This paper provides GCM results and a visual analysis of the relational characteristics both within and across sub-populations involved in the study. It also provides an assessment of observational key factors supporting how different stakeholder voices can be integrated to inform model development and policy recommendations.

    Background Cardiopulmonary resuscitation (CPR) is an intervention used in cases of cardiac arrest to revive patients whose heart has stopped. Because cardiac arrest can have potentially devastating outcomes such as severe neurological deficits even if CPR is performed, patients must be involved in determining in advance if they want CPR in the case of an unexpected arrest. Shared decision making (SDM) facilitates discussions about goals of care regarding CPR in intensive care units (ICUs). Patient decision aids (DAs) are proven to support the implementation of SDM. Many patient DAs about CPR exist, but they are not universally implemented in ICUs in part due to lack of context and cultural adaptation. Adaptation to local context is an important phase of implementing any type of knowledge tool such as patient DAs. User-centered design supported by a wiki platform to perform rapid prototyping has previously been successful in creating knowledge tools adapted to the needs of patients and health professionals (eg, asthma action plans). This project aims to explore how user-centered design and a wiki platform can support the adaptation of an existing DA for CPR to the local context. Objective The primary objective is to use an existing DA about CPR to create a wiki-based DA that is adapted to the context of a single ICU and tailorable to individual patient’s risk factors while employing user-centered design. The secondary objective is to document the use of a wiki platform for the adaptation of patient DAs. Methods This study will be conducted in a mixed surgical and medical ICU at Hôtel-Dieu de Lévis, Quebec, Canada. We plan to involve all 5 intensivists and recruit at least 20 alert and oriented patients admitted to the ICU and their family members if available. In the first phase of this study, we will observe 3 weeks of daily interactions between patients, families, intensivists, and other allied health professionals. We will specifically observe 5 dyads of

    To evaluate the effectiveness of the Comprehensive Voice Rehabilitation Program (CVRP) compared with Vocal Function Exercises (VFEs) to treat functional dysphonia. This is a randomized blinded clinical trial. Eighty voice professionals presented with voice complaints for more than 6 months with a functional dysphonia diagnosis. Subjects were randomized into two voice treatment groups: CVRP and VFE. The rehabilitation program consisted of six voice treatment sessions and three assessment sessions performed before, immediately after, and 1 month after treatment. The outcome measures were self-assessment protocols (Voice-Related Quality of Life [V-RQOL] and Voice Handicap Index [VHI]), perceptual evaluation of vocal quality, and a visual examination of the larynx, both blinded. The randomization process produced comparable groups in terms of age, gender, signs, and symptoms. Both groups had positive outcome measures. The CVRP effect size was 1.09 for the V-RQOL, 1.17 for the VHI, 0.79 for vocal perceptual evaluation, and 1.01 for larynx visual examination. The VFE effect size was 0.86 for the V-RQOL, 0.62 for the VHI, 0.48 for the vocal perceptual evaluation, and 0.51 for larynx visual examination. Only 10% of the patients were lost over the study. Both treatment programs were effective. The probability of a patient improving because of the CVRP treatment was similar to that of the VFE treatment. Copyright © 2016 The Voice Foundation.

    This research aimed to look in depth at the factors affecting the ability of four Sure Start local programmes, based in a multicultural Midlands city, to engage with 'hard-to-reach' populations. A variety of research strategies and methods were employed. Geographical information systems, participatory research methods and interviews were used in order to understand the extent of the challenge, and hear first hand, why parents may not get involved with Sure Start. The mapping exercise involved collation and mapping of postcode data with respect to boundaries and potential and actual users of Sure Start services. This made possible the identification of any geographical patterning in the distribution of service users and non-users. Participatory research methods were used with parents, enabling them to conduct short interviews within their own communities and make sense of the data collected. Interviews were also conducted with 70 parents across the city, recruited through local schools. The results indicate that parental decisions regarding Sure Start are the product of a complex interaction between numerous factors which may act as either barriers or facilitators to service utilization. The results suggest that a multi-method approach to data collection is useful and appropriate in gaining access to those parents who are non-users of the Sure Start services and enabling their voices to be heard. These findings offer some explanations and insight into the apparent ambivalent attitudes of some families toward Sure Start services. Implications for future practice are discussed.

    Dysphonia is more prevalent in teachers than among the general population. The objective of this study was to analyze clinical, vocal, and videolaryngoscopical aspects in dysphonic teachers. Ninety dysphonic teachers were inquired about their voice, comorbidities, and work conditions. They underwent vocal auditory-perceptual evaluation (maximum phonation time and GRBASI scale), acoustic voice analysis, and videolaryngoscopy. The results were compared with a control group consisting of 90 dysphonic nonteachers, of similar gender and ages, and with professional activities excluding teaching and singing. In both groups, there were 85 women and five men (age range 31-50 years). In the controls, the majority of subjects worked in domestic activities, whereas the majority of teachers worked in primary (42.8%) and secondary school (37.7%). Teachers and controls reported, respectively: vocal abuse (76.7%; 37.8%), weekly hours of work between 21 and 40 years (72.2%; 80%), under 10 years of practice (36%; 23%), absenteeism (23%; 0%), sinonasal (66%; 20%) and gastroesophageal symptoms (44%; 22%), hoarseness (82%; 78%), throat clearing (70%; 62%), and phonatory effort (72%; 52%). In both groups, there were decreased values of maximum phonation time, impairment of the G parameter in the GRBASI scale (82%), decrease of F0 and increase of the rest of acoustic parameters. Nodules and laryngopharyngeal reflux were predominant in teachers; laryngopharyngeal reflux, polyps, and sulcus vocalis predominated in the controls. Vocal symptoms, comorbidities, and absenteeism were predominant among teachers. The vocal analyses were similar in both groups. Nodules and laryngopharyngeal reflux were predominant among teachers, whereas polyps, laryngopharyngeal reflux, and sulcus were predominant among controls. Copyright © 2015 The Voice Foundation.

    The aim of the study was to investigate if voice ergonomic risk factors in classrooms correlated with acoustic parameters of teachers' voice production. The voice ergonomic risk factors in the fields of working culture, working postures and indoor air quality were assessed in 40 classrooms using the Voice Ergonomic Assessment in Work Environment - Handbook and Checklist. Teachers (32 females, 8 males) from the above-mentioned classrooms recorded text readings before and after a working day. Fundamental frequency, sound pressure level (SPL) and the slope of the spectrum (alpha ratio) were analyzed. The higher the number of the risk factors in the classrooms, the higher SPL the teachers used and the more strained the males' voices (increased alpha ratio) were. The SPL was already higher before the working day in the teachers with higher risk than in those with lower risk. In the working environment with many voice ergonomic risk factors, speakers increase voice loudness and use more strained voice quality (males). A practical implication of the results is that voice ergonomic assessments are needed in schools. Copyright © 2013 S. Karger AG, Basel.

    The prolonged use or abuse of voice may lead to vocal fatigue and vocal fold tissue damage. School teachers routinely use their voices intensively at work and are therefore at a higher risk of dysphonia. To determine the prevalence of voice disorders among primary school teachers in Lagos, Nigeria, and to explore associated risk factors. Teaching and non-teaching staff from 19 public and private primary schools completed a self-administered questionnaire to obtain information on personal lifestyles, work experience and environment, and voice disorder symptoms. Dysphonia was defined as the presence of at least one of the following: hoarseness, repetitive throat clearing, tired voice or straining to speak. A total of 341 teaching and 155 non-teaching staff participated. The prevalence of dysphonia in teachers was 42% compared with 18% in non-teaching staff. A significantly higher proportion of the teachers reported that voice symptoms had affected their ability to communicate effectively. School type (public/private) did not predict the presence of dysphonia. Statistically significant associations were found for regular caffeinated drink intake (odds ratio [OR] = 3.07; 95% confidence interval [CI]: 1.51-6.62), frequent upper respiratory tract infection (OR = 3.60; 95% CI: 1.39-9.33) and raised voice while teaching (OR = 10.1; 95% CI: 5.07-20.2). Nigerian primary school teachers were at risk for dysphonia. Important environment and personal factors were upper respiratory infection, the need to frequently raise the voice when teaching and regular intake of caffeinated drinks. Dysphonia was not associated with age or years of teaching. © The Author 2014. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

  19. The eyes, ears and collective voice for nuclear transport

    International Nuclear Information System (INIS)

    Green, L.

    2000-01-01

    Transport is a vital part of the nuclear industry and the safety record of radioactive materials transport across the world is excellent. This record is due primarily to well-founded regulations developed by such intergovernmental organisations as the International Atomic Energy Agency and the International Maritime Organisation. It is due, also, to the professionalism of those in the industry. Attitudes to nuclear transport are important. They have the potential, if not heeded, and not responded to sensitively and convincingly to make life very much more difficult for those committed to the safe, reliable and efficient transport of nuclear materials. What is required is a balanced situation, which takes account both of the public's attitudes and industry's need for an efficient operation. The voices of the nuclear transport industry and those who value the industry need to be heard. The World Nuclear Transport Institute was established to provide the nuclear transport industry with the collective eyes, ears and voice in the key intergovernmental organisations which are so important to it. The nuclear transport industry has a safety record which could be regarded as a model for the transport of dangerous goods of all kinds. The industry is situated within a comprehensive and strict regime of national and international standards and regulations. That is the message to be disseminated, and that is the commitment of the World Nuclear Transport Institute as it works to protect and to promote the safe, efficient and reliable transport of radioactive materials.

    2017-01-01

    The prevalence of voice disorders among various educator groups is well known, and voice disorders among music educators are higher than the general classroom educators. Music educators vary with respect to behavioral and personality factors, personal characteristics, type of music taught, job-specific environment, and governmental professional expectations. This study aims to identify risk factors for voice disorders in a heterogeneous population of music educators. An online survey was conducted with 213 respondents. Survey questions addressed demographics, level of education, years of music teaching experience, specialty training, primary teaching assignments and instrument, vocal health behaviors, and diagnoses of voice disorders. Summary statistics and group comparisons are reported. Those whose primary instrument was voice reported a greater frequency of voice disorders. Female and older music educators also had a higher prevalence of voice disorders. Music educators are a heterogeneous group of individuals who require more careful consideration in the prevention and treatment of occupational voice problems. Copyright © 2017 The Voice Foundation.

    Sexual infidelity can be costly to members of both the extra-pair and the paired couple. Thus, detecting infidelity risk is potentially adaptive if it aids in avoiding cuckoldry or loss of parental and relationship investment. Among men, testosterone is inversely related to voice pitch, relationship and offspring investment, and is positively related to the pursuit of short-term relationships, including extra-pair sex. Among women, estrogen is positively related to voice pitch, attractiveness, and the likelihood of extra-pair involvement. Although prior work has demonstrated a positive relationship between men's testosterone levels and infidelity, this study is the first to investigate attributions of infidelity as a function of sexual dimorphism in male and female voices. We found that men attributed high infidelity risk to feminized women's voices, but not significantly more often than did women. Women attributed high infidelity risk to masculinized men's voices at significantly higher rates than did men. These data suggest that voice pitch is used as an indicator of sexual strategy in addition to underlying mate value. The aforementioned attributions may be adaptive if they prevent cuckoldry and/or loss of parental and relationship investment via avoidance of partners who may be more likely to be unfaithful.

    2015-09-01

    Past neuroimaging studies have documented discrete regions of human temporal cortex that are more strongly activated by conspecific voice sounds than by nonvoice sounds. However, the mechanisms underlying this voice sensitivity remain unclear. In the present functional MRI study, we took a novel approach to examining voice sensitivity, in which we applied a signal detection paradigm to the assessment of multivariate pattern classification among several living and nonliving categories of auditory stimuli. Within this framework, voice sensitivity can be interpreted as a distinct neural representation of brain activity that correctly distinguishes human vocalizations from other auditory object categories. Across a series of auditory categorization tests, we found that bilateral superior and middle temporal cortex consistently exhibited robust sensitivity to human vocal sounds. Although the strongest categorization was in distinguishing human voice from other categories, subsets of these regions were also able to distinguish reliably between nonhuman categories, suggesting a general role in auditory object categorization. Our findings complement the current evidence of cortical sensitivity to human vocal sounds by revealing that the greatest sensitivity during categorization tasks is devoted to distinguishing voice from nonvoice categories within human temporal cortex.

    The addition of a fourth type of voice to Titze's voice classification scheme is proposed. This fourth voice type is characterized by primarily stochastic noise behavior and is therefore unsuitable for both perturbation and correlation dimension analysis. Forty voice samples were classified into the proposed four types using narrowband spectrograms. Acoustic, perceptual, and correlation dimension analyses were completed for all voice samples. Perturbation measures tended to increase with voice type. Based on reliability cutoffs, the type 1 and type 2 voices were considered suitable for perturbation analysis. Measures of unreliability were higher for type 3 and 4 voices. Correlation dimension analyses increased significantly with signal type as indicated by a one-way analysis of variance. Notably, correlation dimension analysis could not quantify the type 4 voices. The proposed fourth voice type represents a subset of voices dominated by noise behavior. Current measures capable of evaluating type 4 voices provide only qualitative data (spectrograms, perceptual analysis, and an infinite correlation dimension). Type 4 voices are highly complex and the development of objective measures capable of analyzing these voices remains a topic of future investigation.

    It has been shown that teachers are at risk of developing occupational dysphonia, which accounts for over 25% of all occupational diseases diagnosed in Poland. The most frequently used method of diagnosing voice diseases is videostroboscopy. However, to facilitate objective evaluation of voice efficiency as well as medical certification of occupational voice disorders, it is crucial to implement quantitative methods of voice assessment, particularly voice acoustic analysis. The aim of the study was to assess the results of acoustic analysis in 66 female teachers (aged 40-64 years), including 35 subjects with occupational voice pathologies (e.g., vocal nodules) and 31 subjects with functional dysphonia. The acoustic analysis was performed using the IRIS software, before and after a 30-minute vocal loading test. All participants were subjected also to laryngological and videostroboscopic examinations. After the vocal effort, the acoustic parameters displayed statistically significant abnormalities, mostly lowered fundamental frequency (Fo) and incorrect values of shimmer and noise to harmonic ratio. To conclude, quantitative voice acoustic analysis using the IRIS software seems to be an effective complement to voice examinations, which is particularly helpful in diagnosing occupational dysphonia.

    Rothenberg, Martin; Schutte, Harm K

    2016-11-01

    In 1985, at a conference sponsored by the National Institutes of Health, Martin Rothenberg first described a form of nonlinear source-tract acoustic interaction mechanism by which some sopranos, singing in their high range, can use to reduce the total airflow, to allow holding the note longer, and simultaneously enrich the quality of the voice, without straining the voice. (M. Rothenberg, "Source-Tract Acoustic Interaction in the Soprano Voice and Implications for Vocal Efficiency," Fourth International Conference on Vocal Fold Physiology, New Haven, Connecticut, June 3-6, 1985.) In this paper, we describe additional evidence for this type of nonlinear source-tract interaction in some soprano singing and describe an analogous interaction phenomenon in communication engineering. We also present some implications for voice research and pedagogy. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

  20. Implicit multisensory associations influence voice recognition.

    Directory of Open Access Journals (Sweden)

    Katharina von Kriegstein

    2006-10-01

    Full Text Available Natural objects provide partially redundant information to the brain through different sensory modalities. For example, voices and faces both give information about the speech content, age, and gender of a person. Thanks to this redundancy, multimodal recognition is fast, robust, and automatic. In unimodal perception, however, only part of the information about an object is available. Here, we addressed whether, even under conditions of unimodal sensory input, crossmodal neural circuits that have been shaped by previous associative learning become activated and underpin a performance benefit. We measured brain activity with functional magnetic resonance imaging before, while, and after participants learned to associate either sensory redundant stimuli, i.e. voices and faces, or arbitrary multimodal combinations, i.e. voices and written names, ring tones, and cell phones or brand names of these cell phones. After learning, participants were better at recognizing unimodal auditory voices that had been paired with faces than those paired with written names, and association of voices with faces resulted in an increased functional coupling between voice and face areas. No such effects were observed for ring tones that had been paired with cell phones or names. These findings demonstrate that brief exposure to ecologically valid and sensory redundant stimulus pairs, such as voices and faces, induces specific multisensory associations. Consistent with predictive coding theories, associative representations become thereafter available for unimodal perception and facilitate object recognition. These data suggest that for natural objects effective predictive signals can be generated across sensory systems and proceed by optimization of functional connectivity between specialized cortical sensory modules.

    In this paper, we research an admission control scheme of integrated voice and data CDMA/TDD (Code division multiple access/Time division duplex) system considering asymmetric traffic and power limit. A new user can access the system only if the outage probabilities it experiences on the uplink and downlink time slots are below a threshold value. Based on the power limit the results show the voice and data blocking probabilities under different cell coverage~ arrival rates and various uplink/downlink time slot allocation patterns. Furthermore, multicode and multislot schemes are also evaluated under the presented admission control scheme.

    2014-06-01

    The improving access to psychological therapies initiative has highlighted the importance of managing mental health problems effectively, and research has shown excellent outcomes from cognitive behavioural therapy (CBT) interventions. Patients presenting with functional dysphonia will often also describe psychological distress including anxiety, depression and reduced general well-being, and it is felt that effective voice therapy needs to include the management of psychological well-being. The evidence for the use of CBT enhanced voice therapy is limited to date. Recent research has only started to identify the benefits of this approach and questions regarding how to achieve and maintain competence are essential. Voice therapy outcomes are positive and patients receiving CBT with voice therapy have shown more improvement in their general well-being and distress. CBT is a very well evidenced therapy and recommended by The National Institute for Health and Care Excellence (NICE) as the treatment of choice for mental health difficulties and medically unexplained symptoms. Allied health professionals are increasingly being trained to use CBT skills in the management of a number of symptoms/illnesses, and this should be considered for the management of functional dysphonia. However, there is a need for more research and detailed consideration of how therapists should be trained and supervised and how cost-effective this approach may be.

    2009-04-01

    Full Text Available Abstract Background Within the last decade there has been a growth in the call-centre industry in the UK, with a growing awareness of the voice as an important tool for successful communication. Occupational voice problems such as occupational dysphonia, in a business which relies on healthy, effective voice as the primary professional communication tool, may threaten working ability and occupational health and safety of workers. While previous studies of telephone call-agents have reported a range of voice symptoms and functional vocal health problems, there have been no studies investigating the use and impact of vocal performance in the communication industry within the UK. This study aims to address a significant gap in the evidence-base of occupational health and safety research. The objectives of the study are: 1. to investigate the work context and vocal communication demands for call-agents; 2. to evaluate call-agents' vocal health, awareness and performance; and 3. to identify key risks and training needs for employees and employers within call-centres. Methods and design This is an occupational epidemiological study, which plans to recruit call-centres throughout the UK and Ireland. Data collection will consist of three components: 1. interviews with managers from each participating call-centre to assess their communication and training needs; 2. an online biopsychosocial questionnaire will be administered to investigate the work environment and vocal demands of call-agents; and 3. voice acoustic measurements of a random sample of participants using the Multi-dimensional Voice Program (MDVP. Qualitative content analysis from the interviews will identify underlying themes and issues. A multivariate analysis approach will be adopted using Structural Equation Modelling (SEM, to develop voice measurement models in determining the construct validity of potential factors contributing to occupational dysphonia. Quantitative data will be

    Rana, D.S.; Hurst, G.; Shepstone, L.; Pilling, J.; Cockburn, J.; Crawford, M.

    2005-01-01

    AIM: To compare the efficiency and accuracy of radiology reports generated by voice recognition (VR) against the traditional tape dictation-transcription (DT) method. MATERIALS AND METHODS: Two hundred and twenty previously reported computed radiography (CR) and cross-sectional imaging (CSI) examinations were separately entered into the Radiology Information System (RIS) using both VR and DT. The times taken and errors found in the reports were compared using univariate analyses based upon the sign-test, and a general linear model constructed to examine the mean differences between the two methods. RESULTS: There were significant reductions (p<0.001) in the mean difference in the reporting times using VR compared with DT for the two reporting methods assessed (CR, +67.4; CSI, +122.1 s). There was a significant increase in the mean difference in the actual radiologist times using VR compared with DT in the CSI reports; -14.3 s, p=0.037 (more experienced user); -13.7 s, p=0.014 (less experienced user). There were significantly more total and major errors when using VR compared with DT for CR reports (-0.25 and -0.26, respectively), and in total errors for CSI (-0.75, p<0.001), but no difference in major errors (-0.16, p=0.168). Although there were significantly more errors with VR in the less experienced group of users (mean difference in total errors -0.90, and major errors -0.40, p<0.001), there was no significant difference in the more experienced (p=0.419 and p=0.814, respectively). CONCLUSIONS: VR is a viable reporting method for experienced users, with a quicker overall report production time (despite an increase in the radiologists' time) and a tendency to more errors for inexperienced users

  12. Probing echoic memory with different voices.

    Madden, D J; Bastian, J

    1977-05-01

    Considerable evidence has indicated that some acoustical properties of spoken items are preserved in an "echoic" memory for approximately 2 sec. However, some of this evidence has also shown that changing the voice speaking the stimulus items has a disruptive effect on memory which persists longer than that of other acoustical variables. The present experiment examined the effect of voice changes on response bias as well as on accuracy in a recognition memory task. The task involved judging recognition probes as being present in or absent from sets of dichotically presented digits. Recognition of probes spoken in the same voice as that of the dichotic items was more accurate than recognition of different-voice probes at each of three retention intervals of up to 4 sec. Different-voice probes increased the likelihood of "absent" responses, but only up to a 1.4-sec delay. These shifts in response bias may represent a property of echoic memory which should be investigated further.

    To provide a means of rendering complex computer architectures languages and input/output modalities transparent to experienced and inexperienced users research is being conducted to develop a voice driven/voice response computer graphics imaging system. The system will be used for reconstructing and displaying computed tomography and magnetic resonance imaging scan data. In conjunction with this study an artificial intelligence (Al) control strategy was developed to interface the voice components and support software to the computer graphics functions implemented on the Sun Microsystems 4/280 color graphics workstation. Based on generated text and converted renditions of verbal utterances by the user the Al control strategy determines the user''s intent and develops and validates a plan. The program type and parameters within the plan are used as input to the graphics system for reconstructing and displaying medical image data corresponding to that perceived intent. If the plan is not valid the control strategy queries the user for additional information. The control strategy operates in a conversation mode and vocally provides system status reports. A detailed examination of the various AT techniques is presented with major emphasis being placed on their specific roles within the total control strategy structure. 1.

    2011-06-01

    Teachers are professionals who demand much of their voices and, consequently, present a high risk of developing vocal disorders during the course of employment. To identify factors associated with vocal disorders among teachers. An exploratory cross-sectional study, which investigated 476 teachers in primary and secondary schools in the city of Salvador, Bahia. Teachers answered a questionnaire and were submitted to auditory vocal analysis. The GRBAS was used for the diagnosis of vocal disorders. The study population comprised 82.8% women, teachers with an average age of 40.7 years, teachers with higher education (88.4%), with an average workday of 38 hours per week, average 11.5 years of professional practice and average monthly income of R$1.817.18. The prevalence of voice disorders was 53.6%. (255 teachers). The bivariate analysis showed statistically significant associations between vocal disorders and age above 40 years (PR = 1.83; 95% CI; 1.27-2.64), family history of dysphonia (PR = 1.72; 95% CI; 1.06-2.80), over 20 hours of weekly working hours (PR = 1.66; 95% CI; 1.09-2.52) and presence of chalk dust in the classroom (PR = 1.70; 95% CI; 1.14-2.53). The study concluded that teachers, 40 years old and over, with a family history of dysphonia, working over 20 hours weekly, and teaching in classrooms with chalk dust are more likely to develop voice disorders than others.

    The authors present a computer-based expert computer system called Mammo-Icon, which automatically assists the radiologist's case analysis by reviewing the trigger phrase output of a commercially available voice transcription system in he domain of mammography. A commercially available PC-based voice dictation system is coupled to an expert system implemented on a microcomputer. Software employs the LISP and C computer languages. Mammo-Icon responds to the trigger phrase output of a voice dictation system with a textual discussion of the potential significance of the findings that have been described and a display of reference images that may help the radiologist to confirm a suspected diagnosis or consider additional diagnoses. This results in automatic availability of potentially useful computer-based expert advice, making such systems much more likely to be used in routine clinical practice

    Full Text Available Music is a powerful medium capable of eliciting a broad range of emotions. Although the relationship between language and music is well documented, relatively little is known about the effects of lyrics and the voice on the emotional processing of music and on listeners’ preferences. In the present study, we investigated the effects of vocals in music on participants’ perceived valence and arousal in songs. Participants (N = 50 made valence and arousal ratings for familiar songs that were presented with and without the voice. We observed robust effects of vocal content on perceived arousal. Furthermore, we found that the effect of the voice on enhancing arousal ratings is independent of familiarity of the song and differs across genders and age: females were more influenced by vocals than males; furthermore these gender effects were enhanced among older adults. Results highlight the effects of gender and aging in emotion perception and are discussed in terms of the social roles of music.

    To verify the efficacy of group voice therapy in the stage of readiness and identify which items of the URICA-Voice range are more sensitive to post-therapy change in patients with behavioral dysphonia. An intervention study was conducted on 49 patients with behavioral dysphonia. An eclectic approach to group therapy was implemented over eight sessions, the first and last sessions consisting of assessments. The URICA-Voice range was used to evaluate the stage of readiness at pre- and post-therapy assessments. A descriptive and inferential statistical analysis was implemented for the results. Most participants were female, did not make professional use of voice, and had membranous vocal fold lesions. Most of them were in the Contemplation stage at in both moments, pre- and post-therapy. There was no significant change in the comparison of pre- and post-therapy scores. The majority of patients showed a reduction in the stage of readiness and some advanced to a higher stage. In the comparison of URICA-V range items, seven questions had equal or inferior responses in the post-therapy assessment. There was no statistical difference when comparing the pre- and post-therapy total average score of the URICA-Voice range. There were significant changes in the stage of readiness of patients in pre- and post-group speech therapy assessments.

    The voice is apparently used in quite different manners in different styles of singing. Some of these differences concern the voice source, which varies considerably with loudness, pitch, and mode of phonation. We attempt to describe voice source differences between Classical, Pop, Jazz and Blues styles of singing as produced in a triad melody pattern by a professional female singer in soft, middle and loud phonation. An expert panel was asked to identify these triads as examples of either Classical, Pop, Jazz or Blues. The voice source was analysed by inverse filtering. Subglottal pressure Ps, closed quotient QClosed, glottal compliance (ratio between the air volume contained in a voice pulse and Ps), and the level difference between the two lowest source spectrum partials were analysed in the styles and in four modes of phonation: breathy, flow, neutral, and pressed. The same expert panel rated the degree of pressedness in the entire material. Averages across pitch were calculated for each mode and style and related to their total range of variation in the subject. The glottogram data showed a high correlation with the ratings of pressedness. Based on these correlations a pressedness factor was computed from the glottogram data. A phonation map was constructed with the axes representing mean adduction factor and mean Ps, respectively. In this map Classical was similar to flow phonation, Pop and Jazz to neutral and flow phonation, and Blues to pressed phonation.

    The founders of the Association of Academic Health Sciences Libraries (AAHSL) envisioned the development of a professional organization that would provide a greater voice for academic health sciences libraries, facilitate cooperation and communication with the Association of American Medical Colleges, and create a forum for identifying problems and solutions that are common to academic health sciences libraries. This article focuses on the fulfillment of the "greater voice" vision by describing action and leadership by AAHSL and its members on issues that directly influenced the role of academic health sciences libraries. These include AAHSL's participation in the work that led to the publication of the landmark report, Academic Information in the Academic Health Sciences Center: Roles for the Library in Information Management; its contributions to the recommendations of the Physicians for the Twenty-first Century: The GPEP Report; and the joint publication with the Medical Library Association of Challenge to Action: Planning and Evaluation Guidelines for Academic Health Sciences Libraries.

    2003-10-01

    This study advances the literature on workplace deviance, addressing retaliation victimization in the context of interpersonal mistreatment. Using survey data from 1,167 public-sector employees, the authors investigated experiences of work retaliation victimization and social retaliation victimization among employees who have vocally resisted interpersonal mistreatment. Regression analyses suggest that different victim voice mechanisms trigger different forms of retaliation, depending on the social positions of the mistreatment victim and instigator. Discriminant function analyses demonstrate lower professional, psychological, and physical well-being among mistreated employees who have been further victimized with retaliation. These analyses also reveal health-related costs associated with victim silence--that is, enduring mistreatment without voicing resistance. Results are interpreted in light of theory on power, emotions, and justice in organizations. 2003 APA

  16. Voices used by nurses when communicating with patients and relatives in a department of medicine for older people-An ethnographic study.

    To describe how nurses communicate with older patients and their relatives in a department of medicine for older people in western Sweden. Communication is an essential tool for nurses when working with older patients and their relatives, but often patients and relatives experience shortcomings in the communication exchanges. They may not receive information or are not treated in a professional way. Good communication can facilitate the development of a positive meeting and improve the patient's health outcome. An ethnographic design informed by the sociocultural perspective was applied. Forty participatory observations were conducted and analysed during the period October 2015-September 2016. The observations covered 135 hours of nurse-patient-relative interaction. Field notes were taken, and 40 informal field conversations with nurses and 40 with patients and relatives were carried out. Semistructured follow-up interviews were conducted with five nurses. In the result, it was found that nurses communicate with four different voices: a medical voice described as being incomplete, task-oriented and with a disease perspective; a nursing voice described as being confirmatory, process-oriented and with a holistic perspective; a pedagogical voice described as being contextualised, comprehension-oriented and with a learning perspective; and a power voice described as being distancing and excluding. The voices can be seen as context-dependent communication approaches. When nurses switch between the voices, this indicates a shift in the orientation or situation. The results indicate that if nurses successfully combine the voices, while limiting the use of the power voice, the communication exchanges can become a more positive experience for all parties involved and a good nurse-patient-relative communication exchange can be achieved. Working for improved communication between nurses, patients and relatives is crucial for establishing a positive nurse

    2018-01-01

    Abstract Recognizing the identity of others by their voice is an important skill for social interactions. To date, it remains controversial which parts of the brain are critical structures for this skill. Based on neuroimaging findings, standard models of person-identity recognition suggest that the right temporal lobe is the hub for voice-identity recognition. Neuropsychological case studies, however, reported selective deficits of voice-identity recognition in patients predominantly with right inferior parietal lobe lesions. Here, our aim was to work towards resolving the discrepancy between neuroimaging studies and neuropsychological case studies to find out which brain structures are critical for voice-identity recognition in humans. We performed a voxel-based lesion-behaviour mapping study in a cohort of patients (n = 58) with unilateral focal brain lesions. The study included a comprehensive behavioural test battery on voice-identity recognition of newly learned (voice-name, voice-face association learning) and familiar voices (famous voice recognition) as well as visual (face-identity recognition) and acoustic control tests (vocal-pitch and vocal-timbre discrimination). The study also comprised clinically established tests (neuropsychological assessment, audiometry) and high-resolution structural brain images. The three key findings were: (i) a strong association between voice-identity recognition performance and right posterior/mid temporal and right inferior parietal lobe lesions; (ii) a selective association between right posterior/mid temporal lobe lesions and voice-identity recognition performance when face-identity recognition performance was factored out; and (iii) an association of right inferior parietal lobe lesions with tasks requiring the association between voices and faces but not voices and names. The results imply that the right posterior/mid temporal lobe is an obligatory structure for voice-identity recognition, while the inferior parietal

    We consider a model of integrated voice and data networks. In this model the network flow problem is formulated as a convex optimization problem. The objective function comprises two types of cost functions: the congestion cost functions, which limit the average input traffic to values compatible with the network conditions; and the rate limitation cost functions, which ensure that all conversations are fairly treated. A joint flow control and routing algorithm is constructed which determines the routes for each conversation, and effects flow control by setting voice packet lengths and data input rates in a manner that achieves optimal tradeoff between each user's satisfaction and the cost of network congestion. An additional congestion control protocol is specified which could be used in conjunction with the algorithm to make the latter respond more dynamically to network congestion.

    Occupational voice disorders in Poland account for over 25% of all occupational diseases. The aim of the study was to assess the prevalence of voice problems in the general population of Polish teachers, and identify risk factors for developing voice pathology. The study group comprised 425 female full-time teachers (most of them primary and secondary school, age ranging from 23 to 61 years) and 83 non-teacher women (control) whose jobs did not involve vocal effort, matched for age to the study group. All participants were subjected to a survey using an extensive questionnaire, and to laryngological, phoniatric and videostroboscopic examinations. The overall lifetime vocal symptoms were more frequent in the teachers than in the non-teachers (69 vs. 36%), and in particular it related to permanent and recurrent hoarseness, and dryness in the throat. Mean number of the voice symptoms was 3.21 in teachers and 1.98 in controls (p teachers. Mean maximum phonation time was shorter in teachers than in the controls (14.3 vs. 15.9 s, p dysphonia (that is thought to predispose to such pathology) were found in 32.7% of teachers and 9.6% of control subjects. The probability of developing incomplete glottal closure (odds ratio 13.2x; 95% CI: 1.8-96.8) and hyperfunctional dysphonia (odds ratio 2.7; 95% CI: 1.14-6.44) were significantly higher in the teacher group versus non-teachers. A significant positive relationship was found in teachers between the prevalence of hyperfunctional dysphonia and strained phonation, neck muscle hypertension, instability of voice, self-assessed hyper-arousal, and lifetime vocal effort index (years of employment as a teacher x hours of professional activity/week). The prevalence of vocal nodules and incomplete glottal closure were correlated with incorrect phonation technique parameters, but not with psychological factors. No correlation was found with environmental variables, such as classroom temperature, humidity, airborne dust. The prevalence of

    This paper reports that to provide a means of rendering complex computer architectures, languages, and input/output modalities transparent to experienced and inexperienced users, research is being conducted to develop a voice driven/voice response computer graphics imaging system. The system will be used for reconstructing and displaying computed tomography and magnetic resonance imaging scan data. In conjunction with this study, an artificial intelligence (AI) control strategy was developed to interface the voice components and support software to the computer graphics functions implemented on the Sun Microsystems 4/280 color graphics workstation. Based on generated text and converted renditions of verbal utterances by the user, the AI control strategy determines the user's intent and develops and validates a plan. The program type and parameters within the plan are used as input to the graphics system for reconstructing and displaying medical image data corresponding to that perceived intent. If the plan is not valid, the control strategy queries the user for additional informaiton. The control strategy operates in a conversation mode and vocally provides system status reports. A detailed examination of the various AI techniques is presented with major emphasis being placed on their specific roles within the total control strategy structure

    Right or bilateral anterior temporal damage can impair face recognition, but whether this is an associative variant of prosopagnosia or part of a multimodal disorder of person recognition is an unsettled question, with implications for cognitive and neuroanatomic models of person recognition. We assessed voice perception and short-term recognition of recently heard voices in 10 subjects with impaired face recognition acquired after cerebral lesions. All 4 subjects with apperceptive prosopagnosia due to lesions limited to fusiform cortex had intact voice discrimination and recognition. One subject with bilateral fusiform and anterior temporal lesions had a combined apperceptive prosopagnosia and apperceptive phonagnosia, the first such described case. Deficits indicating a multimodal syndrome of person recognition were found only in 2 subjects with bilateral anterior temporal lesions. All 3 subjects with right anterior temporal lesions had normal voice perception and recognition, 2 of whom performed normally on perceptual discrimination of faces. This confirms that such lesions can cause a modality-specific associative prosopagnosia. PMID:25349193

    The aim of this study was to analyze the efficiency of the voice therapy in children with vocal nodules by using the acoustic analysis and subjective assessment. Thirty-nine patients with vocal fold nodules, aged between 7 and 14, were included in the study. Each subject had voice therapy led by an experienced voice therapist once a week. All diagnostic and follow-up workouts were performed before the voice therapy and after the third or the sixth month. Transoral and/or transnasal videostroboscopic examination and acoustic analysis were achieved using multi-dimensional voice program (MDVP) and subjective analysis with GRBAS scale. As for the perceptual assessment, the difference was significant for four parameters out of five. A significant improvement was found in the acoustic analysis parameters of jitter, shimmer, and noise-to-harmonic ratio. The voice therapy which was planned according to patients' needs, age, compliance and response to therapy had positive effects on pediatric patients with vocal nodules. Acoustic analysis and GRBAS may be used successfully in the follow-up of pediatric vocal nodule treatment.

  15. The Sound of Voice: Voice-Based Categorization of Speakers' Sexual Orientation within and across Languages.

    Directory of Open Access Journals (Sweden)

    Simone Sulpizio

    Full Text Available Empirical research had initially shown that English listeners are able to identify the speakers' sexual orientation based on voice cues alone. However, the accuracy of this voice-based categorization, as well as its generalizability to other languages (language-dependency and to non-native speakers (language-specificity, has been questioned recently. Consequently, we address these open issues in 5 experiments: First, we tested whether Italian and German listeners are able to correctly identify sexual orientation of same-language male speakers. Then, participants of both nationalities listened to voice samples and rated the sexual orientation of both Italian and German male speakers. We found that listeners were unable to identify the speakers' sexual orientation correctly. However, speakers were consistently categorized as either heterosexual or gay on the basis of how they sounded. Moreover, a similar pattern of results emerged when listeners judged the sexual orientation of speakers of their own and of the foreign language. Overall, this research suggests that voice-based categorization of sexual orientation reflects the listeners' expectations of how gay voices sound rather than being an accurate detector of the speakers' actual sexual identity. Results are discussed with regard to accuracy, acoustic features of voices, language dependency and language specificity.

  16. Perceiving a stranger's voice as being one's own: a 'rubber voice' illusion?

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available We describe an illusion in which a stranger's voice, when presented as the auditory concomitant of a participant's own speech, is perceived as a modified version of their own voice. When the congruence between utterance and feedback breaks down, the illusion is also broken. Compared to a baseline condition in which participants heard their own voice as feedback, hearing a stranger's voice induced robust changes in the fundamental frequency (F0 of their production. Moreover, the shift in F0 appears to be feedback dependent, since shift patterns depended reliably on the relationship between the participant's own F0 and the stranger-voice F0. The shift in F0 was evident both when the illusion was present and after it was broken, suggesting that auditory feedback from production may be used separately for self-recognition and for vocal motor control. Our findings indicate that self-recognition of voices, like other body attributes, is malleable and context dependent.

    Professional autonomy may represent the first step to implementing measures that will allow CRNAs to attain a level of independent practice consistent with their clinical and educational training. Autonomy is regarded as an essential ingredient of professionalism and confers independent function at the individual practitioner level. The principle of autonomy refers to the individual's capacity to make independent decisions based on the assumption that he or she possesses the cognitive, psychological, and emotional faculties to make rational decisions. Nursing practice meets the first two criteria of professionalism--competence and dedication to an important social good. The third criterion of professionalism, autonomy, has been a focal point for controversy since the late nineteenth century, in which obedience to supervisors and physicians remained a central focus of nursing ethics teaching until the advent of feminism in the 1970s. This article presents a thorough analysis of these concepts with some thoughts on how understanding the fundamental precepts and further research may not only help maintain the current level of CRNA professional autonomy but serve to guide us to become more autonomous in the future.

    The present study aimed to identify factors associated with self-reported acute and chronic voice disorders among municipal elementary school teachers in the city of Montes Claros, in the State of Minas Gerais, Brazil. The dependent variable, self-reported dysphonia, was determined via a single question, "Have you noticed changes in your voice quality?" and if so, a follow-up question queried the duration of this change, acute or chronic. The independent variables were dichotomized and divided into five categories: sociodemographic and economic data; lifestyle; organizational and environmental data; health-disease processes; and voice. Analyses of associated factors were performed via a hierarchical multiple logistic regression model. The present study included 226 teachers, of whom 38.9% reported no voice disorders, 35.4% reported an acute disorder, and 25.7% reported a chronic disorder. Excessive voice use daily, consuming more than one alcoholic drink per time, and seeking medical treatment because of voice disorders were associated factors for acute and chronic voice disorders. Consuming up to three glasses of water per day was associated with acute voice disorders. Among teachers who reported chronic voice disorders, teaching for over 15 years and the perception of disturbing or unbearable noise outside the school were both associated factors. Identification of organizational, environmental, and predisposing risk factors for voice disorders is critical, and furthermore, a vocal health promotion program may address these issues.

    Increased patient involvement is a goal in contemporary health care, and of importance to the development of patient oriented ICT. In this paper we discuss how the design of patient-user interfaces can affect patient involvement. Our discussion is based on 12 semi-structured interviews with patient users of a web-based solution for patient--doctor communication piloted in Norway. We argue ICT solutions offering a choice of user interfaces on the patient side are preferable to ensure individual accommodation and a high degree of patient involvement. When introducing web-based tools for patient--health professional communication a free-text option should be provided to the patient users.

    The aim of this study was to define the clinical features of psychogenic voice disorder (PVD) and explore the treatment efficiency of voice therapy and psychological evaluation. Fifty-eight patients who received treatment following the PVD diagnosis and had no organic or other functional voice disorders were assessed retrospectively based on laryngoscopic examinations and subjective and objective assessments. Epidemiological characteristics, accompanying organic and psychological disorders, preferred methods of treatment, and previous treatment outcomes were examined for each patient. A comparison was made based on voice disorders and responses to treatment between patients who received psychotherapy and patients who did not. Participants in this study comprised 58 patients, 10 male and 48 female. Voice therapy was applied in all patients, 54 (93.1%) of whom had improvement in their voice. Although all patients were advised to undergo psychological assessment, only 60.3% (35/58) of them underwent psychological assessment. No statistically significant difference was found between patients who did receive psychological support concerning their treatment responses and patients who did not. Relapse occurred in 14.7% (5/34) of the patients who applied for psychological assessment and in 50% (10/20) of those who did not. There was a statistically significant difference in relapse rates, which was higher among patients who did not receive psychological support (P therapy is an efficient treatment method for PVD. However, in the long-term follow-up, relapse of the disease is observed to be higher among patients who failed to follow up on the recommendation for psychological assessment.

    The current study aimed at investigating the immediate effects of a semi-occluded vocal tract exercise with a ventilation mask in a group of contemporary commercial singers. A randomized controlled study was carried out. Thirty professional or semi-professional singers with no voice complaints were randomly divided into two groups on recruitment: an experimental group and a control group. The same warm-up exercise was performed by the experimental group with an occluded ventilation mask placed over the nose and the mouth and by the control group without the ventilation mask. Voice was recorded before and after the exercise. Acoustic and self-assessment analysis were accomplished. The acoustic parameters of the voice samples recorded before and after training were compared, as well as the parameters' variations between the experimental and the control group. Self-assessment results of the experimental and the control group were compared too. Significant changes after the warm-up exercise included jitter, shimmer, and singing power ratio (SPR) in the experimental group. No significant changes were recorded in the control group. Significant differences between the experimental and the control group were found for ΔShimmer and ΔSPR. Self-assessment analysis confirmed a significantly higher phonatory comfort and voice quality perception for the experimental group. The results of the present study support the immediate advantageous effects on singing voice of a semi-occluded vocal tract exercise with a ventilation mask in terms of acoustic quality, phonatory comfort, and voice quality perception in contemporary commercial singers. Long-term effects still remain to be studied. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Interprofessional care is joint working between health care professionals by pooling their skills, knowledge and expertise, to make joint decisions and learn from each other for the benefits of service users and healthcare professionals. Service users involvement is considered as one of the important aspects of planning, management and decision making process in the delivery of health care to service users. Service users' involvement is not the same as public involvement and partnership arrangements in health care. The active involvement and engagement of service users in health care positively contributes to improve quality of care, to promote better health and to shape the future of health services. Service users are always at the centre of health care professionals' values, work ethics and roles. Moreover, service users centred interprofessional team collaboration is very important to deliver effective health services.

    Full Text Available Drugs users have been receiving contradictory treatments thereby promoting their stigma besides hiding and limiting the understanding of the phenomenon. The objective of this study was to investigate how the District Attorneys and Judges are considering and applying the new law which legislates on the conduct of drug use in Brazil. Eleven Law professionals from the Federal District participated in semi-structured interviews divided in three areas: the point of view in relation to the user of drugs, how the law is being applied, and how they conceive the work of the multidisciplinary teams. The results showed very heterogeneous positions, showing that there is no unanimity on the understanding of the new law. For some, there is a shared belief that drugs abuse is a public health problem, for others, it is believed that the user must receive a punishment for his/her illegal act. An effective and efficient interdisciplinary dialogue should allow a reflective action aiming at favoring those who come to justice.

    Students admitted to the solo singing education at the University of Music Dresden, Germany have been submitted to a detailed physical examination of a variety of factors with relevance to voice function since 1959. In the years 1959-1991, this scheme of examinations included X-ray profiles of the singers' vocal tracts. This material of 132 X-rays of voice professionals was used to investigate different laryngeal morphological measures and their relation to vocal fold length. Further, the study aimed to investigate if there are consistent anatomical differences between singers of different voice classifications. The study design used was a retrospective analysis. Vocal fold length could be measured in 29 of these singer subjects directly. These data showed a strong correlation with the anterior-posterior diameter of the subglottis and the trachea as well as with the distance from the anterior contour of the thyroid cartilage to the anterior contour of the spine. These relations were used in an attempt to predict the 132 singers' vocal fold lengths. The results revealed a clear covariation between predicted vocal fold length and voice classification. Anterior-posterior subglottic-tracheal diameter yielded mean vocal fold lengths of 14.9, 16.0, 16.6, 18.4, 19.5, and 20.9mm for sopranos, mezzo-sopranos, altos, tenors, baritones, and basses, respectively. The data support the assumption that there are consistent anatomical laryngeal differences between singers of different voice classifications, which are of relevance to pitch range and timbre of the voice.

    Full Text Available We describe two voice-to-phoneme conversion algorithms for speaker-independent voice-tag creation specifically targeted at applications on embedded platforms. These algorithms (batch mode and sequential are compared in speech recognition experiments where they are first applied in a same-language context in which both acoustic model training and voice-tag creation and application are performed on the same language. Then, their performance is tested in a cross-language setting where the acoustic models are trained on a particular source language while the voice-tags are created and applied on a different target language. In the same-language environment, both algorithms either perform comparably to or significantly better than the baseline where utterances are manually transcribed by a phonetician. In the cross-language context, the voice-tag performances vary depending on the source-target language pair, with the variation reflecting predicted phonological similarity between the source and target languages. Among the most similar languages, performance nears that of the native-trained models and surpasses the native reference baseline.

    To design a speech voice sample text with all phonemes in Mandarin for subjective auditory perceptual evaluation of voice disorders. The principles for design of a speech voice sample text are: The short text should include the 21 initials and 39 finals, this may cover all the phonemes in Mandarin. Also, the short text should have some meanings. A short text was made out. It had 155 Chinese words, and included 21 initials and 38 finals (the final, ê, was not included because it was rarely used in Mandarin). Also, the text covered 17 light tones and one "Erhua". The constituent ratios of the initials and finals presented in this short text were statistically similar as those in Mandarin according to the method of similarity of the sample and population (r = 0.742, P text were statistically not similar as those in Mandarin (r = 0.731, P > 0.05). A speech voice sample text with all phonemes in Mandarin was made out. The constituent ratios of the initials and finals presented in this short text are similar as those in Mandarin. Its value for subjective auditory perceptual evaluation of voice disorders need further study.

    Bozeman, Kenneth Wood

    2013-07-01

    Awareness of interactions between the lower harmonics of the voice source and the first formant of the vocal tract, and of the passive vowel modifications that accompany them, can assist in working out a smooth transition through the passaggio of the male voice. A stable vocal tract length establishes the general location of all formants, including the higher formants that form the singer's formant cluster. Untrained males instinctively shorten the tube to preserve the strong F1/H2 acoustic coupling of voce aperta, resulting in 'yell' timbre. If tube length and shape are kept stable during pitch ascent, the yell can be avoided by allowing the second harmonic to rise above the first formant, creating the balanced timbre of voce chiusa.

    Full Text Available An ideological case study based on medical profession norms during the Third Reich will be used to exemplify the importance of diversity in the manifestations of professional ethics. The German professional medical community banned their Jewish colleagues from treating German citizens. This included legally mandated employment discrimination and outright censure which led to a professional ethic devoid of diverse voices. While the escalation to the T-4 program and medicalized genocide was influenced by many causes, the intentional, ethnocentric-based exclusion of voices was an important contributing element to the chronicled degradation of societal mores. For illustration, six core Jewish values—life, peace, justice, mercy, scholarship, and sincerity of intention—will be detailed for their potential to inspire health-care professionals to defend and protect minorities and for readers to think critically about the role of medical professionalism in Third Reich society. The Jewish teachings highlight the inherent professional obligations physicians have toward their patients in contrast to the Third Reich’s corruption of patient-centered professionalism. More fundamentally, juxtaposing Jewish and Nazi teachings exposes the loss of perspective when a profession’s identity spurns diversity.

    Vocal Nodules (VN) are a functional voice disorder associated with voice misuse and abuse in children. There are few reports addressing vocal parameters in children with VN, especially after a period of vocal rehabilitation. The purpose of this study is to describe measurements of vocal parameters including Fundamental Frequency (FF), Shimmer (S), and Jitter (J), videonasolaryngoscopy examination and clinical perceptual assessment, before and after voice therapy in children with VN. Voice therapy was provided using visual support through Speech-Viewer software. Twenty patients with VN were studied. An acoustical analysis of voice was performed and compared with data from subjects from a control group matched by age and gender. Also, clinical perceptual assessment of voice and videonasolaryngoscopy were performed to all patients with VN. After a period of voice therapy, provided with visual support using Speech Viewer-III (SV-III-IBM) software, new acoustical analyses, perceptual assessments and videonasolaryngoscopies were performed. Before the onset of voice therapy, there was a significant difference (ptherapy period, a significant improvement (pvocal nodules were no longer discernible on the vocal folds in any of the cases. SV-III software seems to be a safe and reliable method for providing voice therapy in children with VN. Acoustic voice parameters, perceptual data and videonasolaryngoscopy were significantly improved after the speech therapy period was completed. Copyright © 2012 Elsevier Ireland Ltd.

    Background: The study presents the evaluation of the phonatory function of the larynx after radiotherapy. The research covered the patients from the rural areas of Poland who revealed neoplastic changes in the glottis area. Material and methods: The test group consisted of 45 men aged 41-78 years with the carcinoma of the larynx with T1 and T2 progression types of cancer, according to the TNM classification. The analysis of laryngeal tone was performed with the digital analyzer Kay Elemetrics Model CSL 4300 and Multi Dimensional Voice Program (MDVP). A stroboscopic test in all the patients with T1 progression revealed the reduction of vibrations. Results: The acoustic analysis of the voice in the pre-treatment group as compared with the control group allowed for differentiation of the following parameters of a definitely pathologic character: Jita, Jitter, RAP, PPQ, vFo, Shimmer, APQ, vAm, NHR, VTI, SPI, and DUV. Conclusions: In the acoustic analysis of voice in the post-radiotherapy group, the following parameters reached values close to the norm: JITA, JITT, RAP, PPQ, vF0, vAM, DUV, and Schimmer dB.

    Full Text Available Person identification, especially in critical environments, has always been a subject of great interest. However, it has gained a new dimension in a world threatened by a new kind of terrorism that uses social networks (e.g. YouTube to broadcast its message. In this new scenario, classical identification methods (such fingerprints or face recognition have been forcedly replaced by alternative biometric characteristics such as voice, as sometimes this is the only feature available. Through the present paper, a new methodology to characterize speakers will be shown. This methodology is benefiting from the advances achieved during the last years in understanding and modelling voice production. The paper hypothesizes that a gender dependent characterization of speakers combined with the use of a new set of biometric parameters extracted from the components resulting from the deconstruction of the voice into its glottal source and vocal tract estimates, will enhance recognition rates when compared to classical approaches. A general description about the main hypothesis and the methodology followed to extract gender-dependent extended biometric parameters are given. Experimental validation is carried out both on a highly controlled acoustic condition database, and on a mobile phone network recorded under non-controlled acoustic conditions.

    Full Text Available Accurate sound visualization of noise sources is required for optimal noise control. Typically, noise measurement systems require microphones, an analog-digital converter, cables, a data acquisition system, etc., which may not be affordable for potential users. Also, many such systems are not highly portable and may not be convenient for travel. Handheld personal electronic devices such as smartphones and digital voice recorders with relatively lower costs and higher performance have become widely available recently. Even though such devices are highly portable, directly implementing them for noise measurement may lead to erroneous results since such equipment was originally designed for voice recording. In this study, external microphones were connected to a digital voice recorder to conduct measurements and the input received was processed for noise visualization. In this way, a low cost, compact sound visualization system was designed and introduced to visualize two actual noise sources for verification with different characteristics: an enclosed loud speaker and a small air compressor. Reasonable accuracy of noise visualization for these two sources was shown over a relatively wide frequency range. This very affordable and compact sound visualization system can be used for many actual noise visualization applications in addition to educational purposes.

    Jekosch, Ute

    2005-01-01

    Foundations of Voice and Speech Quality Perception starts out with the fundamental question of: "How do listeners perceive voice and speech quality and how can these processes be modeled?" Any quantitative answers require measurements. This is natural for physical quantities but harder to imagine for perceptual measurands. This book approaches the problem by actually identifying major perceptual dimensions of voice and speech quality perception, defining units wherever possible and offering paradigms to position these dimensions into a structural skeleton of perceptual speech and voice quality. The emphasis is placed on voice and speech quality assessment of systems in artificial scenarios. Many scientific fields are involved. This book bridges the gap between two quite diverse fields, engineering and humanities, and establishes the new research area of Voice and Speech Quality Perception.

    To assess the usefulness of acoustic analysis with vocal loading test for evaluating the treatment outcomes in occupational voice disorders. Fifty-one female teachers with dysphonia were examined (Voice Handicap Index--VHI, laryngovideostroboscopy and acoustic analysis with vocal loading) before and after treatment. The outcomes of teachers receiving vocal training (group I) were referred to outcomes of group II receiving only voice hygiene instructions. The results of subjective assessment (VHI score) and objective evaluation (acoustic analysis) improved more significantly in group I than in group II. The post-treatment examination revealed a decreased percentage of subjects with deteriorated jitter parameters after vocal loading, particularly in group I. Acoustic analysis with vocal loading test can be a helpful tool in the diagnosis and evaluation of treatment efficacy in occupational dysphonia.

    Collaborative memoirs by co-writers with and without autism can enable the productive interaction of the voices of the writers in ways that can empower rather than exploit the disabled subject. Carly's Voice, co-written by Arthur Fleischmann and his autistic daughter Carly, demonstrates the capacity for such life narratives to facilitate the relational interaction between writers in the negotiation of understandings of disability. Though the text begins by focusing on the limitations of life with autism, it develops into a collaboration which helps both writers move toward new ways of understanding disability and their own and one another's life stories.

  19. Measurement of voice onset time in maxillectomy patients.

    Objective speech evaluation using acoustic measurement is needed for the proper rehabilitation of maxillectomy patients. For digital evaluation of consonants, measurement of voice onset time is one option. However, voice onset time has not been measured in maxillectomy patients as their consonant sound spectra exhibit unique characteristics that make the measurement of voice onset time challenging. In this study, we established criteria for measuring voice onset time in maxillectomy patients for objective speech evaluation. We examined voice onset time for /ka/ and /ta/ in 13 maxillectomy patients by calculating the number of valid measurements of voice onset time out of three trials for each syllable. Wilcoxon's signed rank test showed that voice onset time measurements were more successful for /ka/ and /ta/ when a prosthesis was used (Z = -2.232, P = 0.026 and Z = -2.401, P = 0.016, resp.) than when a prosthesis was not used. These results indicate a prosthesis affected voice onset measurement in these patients. Although more research in this area is needed, measurement of voice onset time has the potential to be used to evaluate consonant production in maxillectomy patients wearing a prosthesis.

    The aim of this study was to investigate the auditory feedback mechanisms and voice quality during phonation in response to a spontaneous pitch change in the auditory feedback. Does the pitch shift reflex (PSR) change voice pitch and voice quality? Quantitative and qualitative voice characteristics were analyzed during the PSR. Twenty-eight healthy subjects underwent transnasal high-speed video endoscopy (HSV) at 8000 fps during sustained phonation [a]. While phonating, the subjects heard their sound pitched up for 700 cents (interval of a fifth), lasting 300 milliseconds in their auditory feedback. The electroencephalography (EEG), acoustic voice signal, electroglottography (EGG), and high-speed-videoendoscopy (HSV) were analyzed to compare feedback mechanisms for the pitched and unpitched condition of the phonation paradigm statistically. Furthermore, quantitative and qualitative voice characteristics were analyzed. The PSR was successfully detected within all signals of the experimental tools (EEG, EGG, acoustic voice signal, HSV). A significant increase of the perturbation measures and an increase of the values of the acoustic parameters during the PSR were observed, especially for the audio signal. The auditory feedback mechanism seems not only to control for voice pitch but also for voice quality aspects.

    An incorrect voice emission is a risk factor for developing occupational voice disorders. The study aimed at assessing the effectiveness of voice therapy in female teachers with dysphonia. The study comprised 133 subjects with voice disorders, taking part in a vocal training programme. A reference group for the present study included 53 teachers with dysphonia. Questionnaire surveys, phoniatric examination and videostroboscopic evaluation were conducted at initial and control examination. In the study group, an improvement after the vocal training was noted in most of the reported symptoms and also in some quantitative parameters of phoniatric examinations compared to the findings for the reference group. The number of patients who assessed their voice as normal increased significantly after the vocal training (2.3 vs. 46.6%). A significant increase in the mean maximum phonation time, from 13.3 to 16.6 s, was observed. The same applied to voice frequency range (increase from 171 to 226.8 Hz). The outcomes of vocal training, such as a subjective improvement of voice quality and an increase in the quantitative parameters (prolonged maximum phonation time, extended voice range) seem to be important parameters for monitoring the effectiveness of training in correct voice emission. 2008 S.

    2001-06-01

    The Department of Radiology at the University of Utah Health Sciences Center has been in the process of transitioning from the traditional film-based department to a digital imaging department for the past 2 years. The department is now transitioning from the traditional method of dictating reports (dictation by radiologist to transcription to review and signing by radiologist) to a voice recognition system. The transition to digital operations will not be complete until we have the ability to directly interface the dictation process with the image review process. Voice recognition technology has advanced to the level where it can and should be an integral part of the new way of working in radiology and is an integral part of an efficient digital imaging department. The transition to voice recognition requires the task of identifying the product and the company that will best meet a department's needs. This report introduces the methods we used to evaluate the vendors and the products available as we made our purchasing decision. We discuss our evaluation method and provide a checklist that can be used by other departments to assist with their evaluation process. The criteria used in the evaluation process fall into the following major categories: user operations, technical infrastructure, medical dictionary, system interfaces, service support, cost, and company strength. Conclusions drawn from our evaluation process will be detailed, with the intention being to shorten the process for others as they embark on a similar venture. As more and more organizations investigate the many products and services that are now being offered to enhance the operations of a radiology department, it becomes increasingly important that solid methods are used to most effectively evaluate the new products. This report should help others complete the task of evaluating a voice recognition system and may be adaptable to other products as well.

    Conclusions: The prevalence of voice disorders among outpatients’ physicians in Slovenia is high and is comparable to the incidence of voice problems in Slovenian teachers. URI is the most common cause of these voice problems. GERD, allergies and an age over 40 years were stated as the risk factors for voice disorders. In order to reduce the extent of voice problems, lessons on vocal hygiene, and additional information about diseases causing voice disorders should be included in their postgraduate education.

  10. Obligatory and facultative brain regions for voice-identity recognition.

    Recognizing the identity of others by their voice is an important skill for social interactions. To date, it remains controversial which parts of the brain are critical structures for this skill. Based on neuroimaging findings, standard models of person-identity recognition suggest that the right temporal lobe is the hub for voice-identity recognition. Neuropsychological case studies, however, reported selective deficits of voice-identity recognition in patients predominantly with right inferior parietal lobe lesions. Here, our aim was to work towards resolving the discrepancy between neuroimaging studies and neuropsychological case studies to find out which brain structures are critical for voice-identity recognition in humans. We performed a voxel-based lesion-behaviour mapping study in a cohort of patients (n = 58) with unilateral focal brain lesions. The study included a comprehensive behavioural test battery on voice-identity recognition of newly learned (voice-name, voice-face association learning) and familiar voices (famous voice recognition) as well as visual (face-identity recognition) and acoustic control tests (vocal-pitch and vocal-timbre discrimination). The study also comprised clinically established tests (neuropsychological assessment, audiometry) and high-resolution structural brain images. The three key findings were: (i) a strong association between voice-identity recognition performance and right posterior/mid temporal and right inferior parietal lobe lesions; (ii) a selective association between right posterior/mid temporal lobe lesions and voice-identity recognition performance when face-identity recognition performance was factored out; and (iii) an association of right inferior parietal lobe lesions with tasks requiring the association between voices and faces but not voices and names. The results imply that the right posterior/mid temporal lobe is an obligatory structure for voice-identity recognition, while the inferior parietal lobe is

  11. The Belt voice: Acoustical measurements and esthetic correlates

    Science.gov (United States)

    Bounous, Barry Urban

    This dissertation explores the esthetic attributes of the Belt voice through spectral acoustical analysis. The process of understanding the nature and safe practice of Belt is just beginning, whereas the understanding of classical singing is well established. The unique nature of the Belt sound provides difficulties for voice teachers attempting to evaluate the quality and appropriateness of a particular sound or performance. This study attempts to provide answers to the question "does Belt conform to a set of measurable esthetic standards?" In answering this question, this paper expands on a previous study of the esthetic attributes of the classical baritone voice (see "Vocal Beauty", NATS Journal 51,1) which also drew some tentative conclusions about the Belt voice but which had an inadequate sample pool of subjects from which to draw. Further, this study demonstrates that it is possible to scientifically investigate the realm of musical esthetics in the singing voice. It is possible to go beyond the "a trained voice compared to an untrained voice" paradigm when evaluating quantitative vocal parameters and actually investigate what truly beautiful voices do. There are functions of sound energy (measured in dB) transference which may affect the nervous system in predictable ways and which can be measured and associated with esthetics. This study does not show consistency in measurements for absolute beauty (taste) even among belt teachers and researchers but does show some markers with varying degrees of importance which may point to a difference between our cognitive learned response to singing and our emotional, more visceral response to sounds. The markers which are significant in determining vocal beauty are: (1) Vibrancy-Characteristics of vibrato including speed, width, and consistency (low variability). (2) Spectral makeup-Ratio of partial strength above the fundamental to the fundamental. (3) Activity of the voice-The quantity of energy being produced. (4

    Studies on the effectiveness of preventive voice care programs have focused mainly on voice parameters. Psychological parameters, however, have not been investigated in detail so far. The effect of a voice training program for German student teachers on psychological health parameters was investigated in a longitudinal study. The sample of 204 student teachers was divided into the intervention group (n = 123), who participated in the voice training program, and the control group (n = 81), who received no voice training. Voice training contained ten 90-min group courses and an individual visit by the voice trainer in a teaching situation with feedback afterwards. Participants were asked to fill out questionnaires (self-efficacy, Short-Form Health Survey, self-consciousness, voice self-concept, work-related behaviour and experience patterns) at the beginning and the end of their student teacher training period. The training program showed significant positive influences on psychological health, voice self-concept (i.e. more positive perception and increased awareness of one's own voice) and work-related coping behaviour in the intervention group. On average, the mental health status of all participants reduced over time, whereas the status in the trained group diminished significantly less than in the control group. Furthermore, the trained student teachers gained abilities to cope with work-related stress better than those without training. The training program clearly showed a positive impact on mental health. The results maintain the importance of such a training program not only for voice health, but also for wide-ranging aspects of constitutional health.

  13. Who speaks for extinct nations? The Beothuk and narrative voice

    Full Text Available The Beothuk of Newfoundland were among the first inhabitants of North America to encounter European explorers and settlers. By the first part of the nineteenth century the Beothuk were extinct, exterminated by the fishers and soldiers and settlers of western Europe. The last Beothuk was a woman named Shanadithit. She was captured and lived with white settlers for a few years before she died in 1829. Today all that remains of the Beothuk nation, which once numbered seven hundred to one thousand people, are some bones, arrowheads, tools, written records of explorers and settlers, and copies of drawings by Shanadithit in the Newfoundland Museum. In recent years several writers (all are white and male have written fiction and poetry and drama about the Beothuk, including Peter Such (Riverrun, 1973, Paul O'Neill (Legends of a Lost Tribe, 1976, Sid Stephen (Beothuk Poems, 1976, Al Pittman ("Shanadithit," 1978, Geoffrey Ursell (The Running of the Deer; A Play, 1981, Donald Gale (Sooshewan: A Child of the Beothuk, 1988, and Kevin Major (Blood Red Ochre, 1990. A recurring theme in all these narratives is the theme of regret and guilt. These narrative accounts of the Beothuk raise significant questions about voice and narrative, including: Who can speak for Native peoples? Who can speak for extinct peoples? Are there peoples without voices? How is voice historically determined? What is the relationship between voice and power? How are the effects of voice generated? What is an authentic voice? How is voice related to the illusion of presence? What is the relation between voice and silence? In examining contemporary narrative accounts of the Beothuk my goal is to reveal the rhetorical ways in which the Beothuk are given voice(s and to interrogate the ethical and pedagogical implications of contemporary authors revisiting and revisioning and re-voicing a nation of people long extinct.

    Vocal events offer not only semantic-linguistic content but also information about the identity and the emotional-motivational state of the speaker. Furthermore, most vocal events have implications for our actions and therefore include action-related features. But the relevance and irrelevance of vocal features varies from task to task. The present study investigates binding processes for perceptual and action-related features of spoken words and their modulation by the task representation of the listener. Participants reacted with two response keys to eight different words spoken by a male or a female voice (Experiment 1) or spoken by an angry or neutral male voice (Experiment 2). There were two instruction conditions: half of participants learned eight stimulus-response mappings by rote (SR), and half of participants applied a binary task rule (TR). In both experiments, SR instructed participants showed clear evidence for binding processes between voice and response features indicated by an interaction between the irrelevant voice feature and the response. By contrast, as indicated by a three-way interaction with instruction, no such binding was found in the TR instructed group. These results are suggestive of binding and shielding as two adaptive mechanisms that ensure successful communication and action in a dynamic social environment.

    2015-06-01

    Nurse managers have a key role in creating positive work environments where safe, high-quality care is consistently provided. This requires a broad range of skills to be successful within today's complex health care environment; however, managers are frequently selected based on their clinical expertise and are offered little formal preparation for this leadership role. We conducted three focus groups with 20 nurse managers to understand their professional development needs. Transcripts were analyzed using conventional content analysis. Three themes emerged: Managing Versus Leading, Gaining a Voice, and Garnering Support. Managers focused on daily tasks, such as matching staffing to patient needs. However, the data suggested gaps in foundational management skills, such as understanding organizational behavior, use of data to make decisions, and refined problem-solving skills. Professional development activities focusing on higher level leadership competencies could assist managers to be more successful in this challenging, but critical, role.

  20. Voice disorder in systemic lupus erythematosus.

    Directory of Open Access Journals (Sweden)

    Milena S F C de Macedo

    Full Text Available Systemic lupus erythematosus (SLE is a chronic disease characterized by progressive tissue damage. In recent decades, novel treatments have greatly extended the life span of SLE patients. This creates a high demand for identifying the overarching symptoms associated with SLE and developing therapies that improve their life quality under chronic care. We hypothesized that SLE patients would present dysphonic symptoms. Given that voice disorders can reduce life quality, identifying a potential SLE-related dysphonia could be relevant for the appraisal and management of this disease. We measured objective vocal parameters and perceived vocal quality with the GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain scale in SLE patients and compared them to matched healthy controls. SLE patients also filled a questionnaire reporting perceived vocal deficits. SLE patients had significantly lower vocal intensity and harmonics to noise ratio, as well as increased jitter and shimmer. All subjective parameters of the GRBAS scale were significantly abnormal in SLE patients. Additionally, the vast majority of SLE patients (29/36 reported at least one perceived vocal deficit, with the most prevalent deficits being vocal fatigue (19/36 and hoarseness (17/36. Self-reported voice deficits were highly correlated with altered GRBAS scores. Additionally, tissue damage scores in different organ systems correlated with dysphonic symptoms, suggesting that some features of SLE-related dysphonia are due to tissue damage. Our results show that a large fraction of SLE patients suffers from perceivable dysphonia and may benefit from voice therapy in order to improve quality of life.
