Overlapping transcripts in opposite orientations can potentially form perfect sense-antisense duplex RNA. Recently, several studies have revealed the extent of natural antisense transcripts (NATs) and their role in important biological phenomena also in higher organisms. In order to test the hypothesis that the function of NATs in man might represent an essential element in the regulation of gene expression, especially at transcriptional level, in this study we planned to look for, systematically examine, and characterize NATs belonging in the human genome to the tumour suppressor class of genes, so to identify physiological (and potentially pathological) modulators in this gene class

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

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 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.
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

Transmasculine people assigned female gender at birth but who do not identify with this classification have traditionally received little consideration in the voice literature. Existing analyses tend to be focused on evaluating speaker voice characteristics, whereas other factors that contribute to the production of vocal gender have remained underexplored. Most studies rely on researcher-centred perspectives, whereas very little is known about how transmasculine people themselves experience and make sense of their vocal situations. To explore how participants described their subjective gender positionings; which gender attributions they wished to receive from others; which gender they self-attributed to their voices; which gender attributions they had received from others; and how far participants were satisfied with the gender-related aspects of their vocal situations. Transcripts of semi-structured interviews with 14 German-speaking transmasculine people served as the original data corpus. Sections in which participants described the gender-related aspects of their vocal situations and that were relevant to the current research objectives were selected and explored using qualitative content analysis. The analysis revealed diverse accounts pertaining to the factors that contribute to the production of vocal gender for individual participants and variable levels of satisfaction with vocal gender presentation and attribution. Transmasculine people need to be regarded as a heterogeneous population and clinical practice needs to follow a client-centred, individualized approach. © 2016 Royal College of Speech and Language Therapists.
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

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.

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.

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.

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.

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.
Transcription skills are crucially important to all phoneticians, and particularly for speech and language therapists who may use transcriptions to make decisions about diagnosis and intervention. Whilst interest in factors affecting transcription accuracy is increasing, there are still a number of issues that are yet to be investigated. The present paper considers how the number of voices and the number of repetitions affects the transcription of nonsense words. Thirty-two students in their second year of study for a BSc in Speech and Language Therapy were participants in an experiment. They heard two nonsense words presented 10 times in either one or two voices. Results show that the number of voices did not affect accuracy, but that accuracy increased between six and ten repetitions. The reasons behind these findings, and implications for teaching and learning, and further research are discussed.

Voice over IP (VoIP) and Internet Multimedia Subsystem technologies (IMS) are rapidly being adopted by consumers, enterprises, governments and militaries. These technologies offer higher flexibility and more features than traditional telephony (PSTN) infrastructures, as well as the potential for lower cost through equipment consolidation and, for the consumer market, new business models. However, VoIP systems also represent a higher complexity in terms of architecture, protocols and implementation, with a corresponding increase in the potential for misuse.

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.

Full Text Available In the 20th century, one of the most widespread of the voice training methods that start with the concepts “natural voice” and “the rediscovery of voice” is the Linklater Method. The primary target group of this method is actors. With its exercises designed for the "reconstruction of the body, the voice and the mind", this method aims at utilizing the innate voice capacity. As a multidisciplinary method fostered by many a scientific discipline and Eastern teaching, Linklater method comes with a language that is imbued with sophisticated and metaphorical expressions, scientific terminology and acting jargon, which makes the method prone to false and/or superficial references. The target of the present study is to explicate with a “trainer's perspective” the fundamental concepts and propositions of the Linklater Method, most notably the “natural voice”. Also, the present study aims at analysing the relation between the basic practices of the method and recent scientific data, thus examining the mental substructure these practices are based on and their physical/technical goals. In this direction, the present study involves the adopting of a general framework with respect to the inclinations and scientific sources of voice training in the 20th century that affected Linklater's propositions, a simplified summarisation of the neuro-anatomic process producing the voice, the selection of exercises on which the principles and goals of the method can be seen concretely and the grouping of these exercises under titles pertaining to the four basic steps of voice production. In the conclusion part of the study, it is argued that this method, despite being regarded as “alternative/experimental” when compared to conventional methods in Turkey, is one of the mainstream methods in contemporary voice training and that it is shaped through a multi-purpose system whose aim is not only voice training but also to develop the creativity and
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.

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.

The first radio-equipped control tower in the United States opened at the Cleveland Municipal Airport in 1930. From that time to the present, voice radio communications have played a primary role in air safety. Verbal communications in air traffic control (ATC) operations have been frequently cited as causal factors in operational errors and pilot deviations in the FAA Operational Error and Deviation System, the NASA Aviation Safety Reporting System (ASRS), and reports derived from government sponsored research projects. Collectively, the data provided by these programs indicate that communications constitute a significant problem for pilots and controllers. Although the communications problem was well known the research literature was fragmented, making it difficult to appreciate the various types of verbal communications problems that existed and their unique influence on the quality of ATC/pilot communications. This is a survey of the voice radio communications literature. The 43 reports in the review represent survey data, field studies, laboratory studies, narrative reports, and reviews. The survey topics pertain to communications taxonomies, acoustical correlates and cognitive/psycholinguistic perspectives. Communications taxonomies were used to identify the frequency and types of information that constitute routine communications, as well as those communications involved in operational errors, pilot deviations, and other safety-related events. Acoustical correlate methodologies identified some qualities of a speaker's voice, such as loudness, pitch, and speech rate, which might be used potentially to monitor stress, mental workload, and other forms of psychological or physiological factors that affect performance. Cognitive/psycho-linguistic research offered an information processing perspective for understanding how pilots' and controllers' memory and language comprehension processes affect their ability to communicate effectively with one another.

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.

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
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.

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.
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.

Plague is an acute and often fatal zoonotic disease caused by the bacterium Yersinia pestis. Y. pestis mainly cycles between small mammals and their fleas; however, it has the potential to infect humans and frequently causes fatalities if left untreated. It is often considered a disease of the past; however, since the late 1800s, plagueis geographic range has expanded greatly, posing new threats in previously unaffected regions of the world, including the Western United States. A literature search was conducted using Internet resources and databases. The keywords chosen for the searches included plague, Yersinia pestis, management, control, wildlife, prairie dogs, fleas, North America, and mammals. Keywords were used alone or in combination with the other terms. Although this search pertains mostly to North America, citations were included from the international research community, as well. Databases and search engines used included Google (http://www.google.com), Google Scholar (http://scholar.google.com), SciVerse Scopus (http://www.scopus.com), ISI Web of Knowledge (http://apps.isiknowledge.com), and the USGS Library's Digital Desktop (http://library.usgs.gov). The literature-cited sections of manuscripts obtained from keyword searches were cross-referenced to identify additional citations or gray literature that was missed by the Internet search engines. This Open-File Report, published as an Internet-accessible bibliography, is intended to be periodically updated with new citations or older references that may have been missed during this compilation. Hence, the authors would be grateful to receive notice of any new or old papers that the audience (users) think need to be included.

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.

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...

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

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

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.

Full Text Available This paper presents a method for automatic music transcription applied to audio recordings of a cappella performances with multiple singers. We propose a system for multi-pitch detection and voice assignment that integrates an acoustic and a music language model. The acoustic model performs spectrogram decomposition, extending probabilistic latent component analysis (PLCA using a six-dimensional dictionary with pre-extracted log-spectral templates. The music language model performs voice separation and assignment using hidden Markov models that apply musicological assumptions. By integrating the two models, the system is able to detect multiple concurrent pitches in polyphonic vocal music and assign each detected pitch to a specific voice type such as soprano, alto, tenor or bass (SATB. We compare our system against multiple baselines, achieving state-of-the-art results for both multi-pitch detection and voice assignment on a dataset of Bach chorales and another of barbershop quartets. We also present an additional evaluation of our system using varied pitch tolerance levels to investigate its performance at 20-cent pitch resolution.

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 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.

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
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.

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 ...
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.

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.

Because of its exciting potential to improve clinical service, as well as reduce costs, a voice recognition system for radiological dictation was recently installed at our institution. This system will be clinically successful if it dramatically reduces radiology report turnaround time without substantially affecting radiologist dictation and editing time. This report summarizes an observer study currently under way in which radiologist reporting times using the traditional transcription system and the voice recognition system are compared. Four radiologists are observed interpreting portable intensive care unit (ICU) chest examinations at a workstation in the chest reading area. Data are recorded with the radiologists using the transcription system and using the voice recognition system. The measurements distinguish between time spent performing clerical tasks and time spent actually dictating the report. Editing time and the number of corrections made are recorded. Additionally, statistics are gathered to assess the voice recognition system's impact on the report cycle time -- the time from report dictation to availability of an edited and finalized report -- and the length of reports.

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. All rights reserved.

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 Â© 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.

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.

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.
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.

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.

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.

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%.

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.
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

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.

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.

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 application of new and less biased methods to study the transcriptional output from genomes, such as tiling arrays and deep sequencing, has revealed that most of the genome is transcribed and that there is substantial overlap of transcripts derived from the two strands of DNA. In protein coding...... regions, the map of transcripts is very complex due to small transcripts from the flanking ends of the transcription unit, the use of multiple start and stop sites for the main transcript, production of multiple functional RNA molecules from the same primary transcript, and RNA molecules made...... by independent transcription from within the unit. In genomic regions separating those that encode proteins or highly abundant RNA molecules with known function, transcripts are generally of low abundance and short-lived. In most of these cases, it is unclear to what extent a function is related to transcription...

This paper brings forth the voices of adult Aboriginal First Nations community members who gathered in focus groups to discuss the problem of youth suicide on their reserves. Our approach emphasizes multilevel (e.g., individual, family, and broader ecological systems) factors viewed by participants as relevant to youth suicide. Wheaton's conceptualization of stressors and Evans-Campbell's multilevel classification of the impacts of historical trauma are used as theoretical and analytic guides. Thematic analysis of qualitative data transcripts revealed a highly complex intersection of stressors, traumas, and social problems seen by community members as underlying mechanisms influencing heightened levels of Aboriginal youth suicidality. Our multilevel coding approach revealed that suicidal behaviors were described by community members largely as a problem with deep historical and contemporary structural roots, as opposed to being viewed as individualized pathology.

, for example there are studies that have strongly criticized focus groups, interviews and surveys (e.g. Ulwick, 2002; Goffin et al, 2010; Sandberg, 2002). In particular, a point is made that, “…traditional market research and development approaches proved to be particularly ill-suited to breakthrough products...... the voice of the customer (VoC) through market research is well documented (Davis, 1993; Mullins and Sutherland, 1998; Cooper et al., 2002; Flint, 2002; Davilla et al., 2006; Cooper and Edgett, 2008; Cooper and Dreher, 2010; Goffin and Mitchell, 2010). However, not all research methods are well received......” (Deszca et al, 2010, p613).

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.

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.
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.

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 aim of this study was to assess the applicability of Voice Handicap Index (VHI) to the evaluation of effectiveness of functional voice disorders treatment in teachers. The subjects were 45 female teachers with functional dysphonia who evaluated their voice problems according to the subjective VHI scale before and after phoniatric management. Group I (29 patients) were subjected to vocal training, whereas group II (16 patients) received only voice hygiene instructions. The results demonstrated that differences in the mean VHI score before and after phoniatric treatment were significantly higher in group 1 than in group II (p teacher's dysphonia.

The development of voice activated panic button application aims to design faster early notification of hazardous condition in community to the nearest police by using speech as the detector where the current application still applies touch-combination on screen and use coordination of orders from control center then the early notification still takes longer time. The method used in this research was by using voice recognition as the user voice detection and haversine formula for the comparison of closest distance between the user and the police. This research was equipped with auto sms, which sent notification to the victim’s relatives, that was also integrated with Google Maps application (GMaps) as the map to the victim’s location. The results show that voice registration on the application reaches 100%, incident detection using speech recognition while the application is running is 94.67% in average, and the auto sms to the victim relatives reaches 100%.

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.

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.

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.

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 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.

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 Â© 2016 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

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.
Psychosomatic disorders are defined as disorders characterized by physiological changes that originate partially from emotional factors. This article aims to discuss the psychosomatic disorders of the oral cavity with a revised working type classification. The author has added one more subset to the existing classification, i.e., disorders caused by altered perception of dentofacial form and function, which include body dysmorphic disorder. The author has also inserted delusional halitosis under the miscellaneous disorders classification of psychosomatic disorders and revised the already existing classification proposed for the psychosomatic disorders pertaining to dental practice. After the inclusion of the subset (disorders caused by altered perception of dentofacial form and function), the terminology "psychosomatic disorders of the oral cavity" is modified to "psychosomatic disorders pertaining to dental practice".

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.

Full Text Available Multimedia telephony is a delay-sensitive application. Packet losses, relatively less critical than delay, are allowed up to a certain threshold. They represent the QoS constraints that have to be respected to guarantee the operation of the telephony service and user satisfaction. In this work we introduce a new smartphone architecture characterized by two process levels called application processor (AP and mobile termination (MT, respectively. Here, they communicate through a serial channel. Moreover, we focus our attention on two very important UMTS services: voice and video telephony. Through a simulation study the impact of voice and video telephony is evaluated on the structure considered using the protocols known at this moment to realize voice and video telephony
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.

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.

Full Text Available Gene regulatory networks lie at the heart of cellular computation. In these networks, intracellular and extracellular signals are integrated by transcription factors, which control the expression of transcription units by binding to cis-regulatory regions on the DNA. The designs of both eukaryotic and prokaryotic cis-regulatory regions are usually highly complex. They frequently consist of both repetitive and overlapping transcription factor binding sites. To unravel the design principles of these promoter architectures, we have designed in silico prokaryotic transcriptional logic gates with predefined input-output relations using an evolutionary algorithm. The resulting cis-regulatory designs are often composed of modules that consist of tandem arrays of binding sites to which the transcription factors bind cooperatively. Moreover, these modules often overlap with each other, leading to competition between them. Our analysis thus identifies a new signal integration motif that is based upon the interplay between intramodular cooperativity and intermodular competition. We show that this signal integration mechanism drastically enhances the capacity of cis-regulatory domains to integrate signals. Our results provide a possible explanation for the complexity of promoter architectures and could be used for the rational design of synthetic gene circuits.

To verify the influence of sleep quality on the voice. Descriptive and analytical cross-sectional study. Data were collected by an online or printed survey divided in three parts: (1) demographic data and vocal health aspects; (2) self-assessment of sleep and vocal quality, and the influence that sleep has on voice; and (3) sleep and voice self-assessment inventories-the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), and the Voice Handicap Index reduced version (VHI-10). A total of 862 people were included (493 women, 369 men), with a mean age of 32 years old (maximum age of 79 and minimum age of 18 years old). The perception of the influence that sleep has on voice showed a difference (P influence a voice handicap are vocal self-assessment, ESS total score, and self-assessment of the influence that sleep has on voice. The absence of daytime sleepiness is a protective factor (odds ratio [OR] > 1) against perceived voice handicap; the presence of daytime sleepiness is a damaging factor (OR influences voice. Perceived poor sleep quality is related to perceived poor vocal quality. Individuals with a voice handicap observe a greater influence of sleep on voice than those without.

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.

WRKY transcription factors are one of the largest families of transcriptional regulators found exclusively in plants. They have diverse biological functions in plant disease resistance, abiotic stress responses, nutrient deprivation, senescence, seed and trichome development, embryogenesis, as well as additional developmental and hormone-controlled processes. WRKYs can act as transcriptional activators or repressors, in various homo- and heterodimer combinations. Here we review recent progress on the function of WRKY transcription factors in Arabidopsis and other plant species such as rice, potato, and parsley, with a special focus on abiotic, developmental, and hormone-regulated processes.

Full Text Available Drawing on Mikhail Bakhtin’s theory of double-voicedness and James Scott’s theory of public and hidden transcripts, this essay investigates the colonial context of Romans 13:1–7 with particular attention to the Roman imperial cult. It is my contention that Paul attempts to persuade the audience to resist the imperial cult, whilst negotiating colonial power and authority. It is assumed that colonial discourse is, by nature, a double-voiced discourse in that the public transcript of the dominant and the hidden transcript of the suppressed coexist in a continued state of internal tension and conflict. Seen in this light, Paul as a colonised subject parodies the public transcript of the elites in his own hidden transcript. However, Paul’s doubled-voiced discourse finally turns out to be subversive against the dominant culture by suggesting that ultimate honour, fear, and authority should not be due to the rulers of the Roman Empire but to God.

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
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.

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.
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.

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.

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.

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.
From being a fictional element in sci-fi, voice control has become a reality, with inventions such as Apple's Siri, and interactive voice response (IVR) when calling your doctor's office. The combination of radio’s strength as a hands-free medium, public radio’s mission to reach across all platforms and the rise of voice makes up a relevant intersection; voice controlled public radio in Sweden. This thesis has aimed to investigate how radio listeners wish to interact using voice control to li...

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.

Dictation of scientific articles has been recognised as an efficient method for producing high-quality, first article drafts. However, standardised transcription service by a secretary may not be available for all researchers and voice recognition software (VRS) may therefore be an alternative. The purpose of this study was to evaluate the out-of-the-box accuracy of VRS. Eleven young researchers without dictation experience dictated the first draft of their own scientific article after thorough preparation according to a pre-defined schedule. The dictate transcribed by VRS was compared with the same dictate transcribed by an experienced research secretary, and the effect of adding words to the vocabulary of the VRS was investigated. The number of errors per hundred words was used as outcome. Furthermore, three experienced researchers assessed the subjective readability using a Likert scale (0-10). Dragon Nuance Premium version 12.5 was used as VRS. The median number of errors per hundred words was 18 (range: 8.5-24.3), which improved when 15,000 words were added to the vocabulary. Subjective readability assessment showed that the texts were understandable with a median score of five (range: 3-9), which was improved with the addition of 5,000 words. The out-of-the-box performance of VRS was acceptable and improved after additional words were added. Further studies are needed to investigate the effect of additional software accuracy training.

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.

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.

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.

The analyses presented pertain to loss of coolant accidents (LOCA), loss of coolant flow accidents (LOFA) and loss of vacuum accidents (LOVA). These types of accidents may jeopardise components and plasma vessel integrity and cause radioactivity mobilisation. The analyses reviewed have been performed under the assumption that the plasma facing components are protected by a carbon based armour. Accidental temperatures and pressure transients are quantified, the possibility of reaction products combustion is investigated and worst case accidental public doses are assessed. On this basis, design recommendations are given and design features such as low plasma facing components armour temperatures (on almost the entire surface) and inert gas adjacent to the vacuum vessel have been implemented.

Vulnerability of man-made infrastructure to Earth-directed space weather events is a serious concern for today's technology-dependent society. Space weather-driven geomagnetically induced currents (GICs) can disrupt operation of extended electrically conducting technological systems. The threat of adverse impacts on critical technological infrastructure, like power grids, oil and gas pipelines, and communication networks, has sparked renewed interest in extreme space weather. Because extreme space weather events have low occurrence rate but potentially high impact, this presents a major challenge for our understanding of extreme GIC activity. In this chapter, we discuss some of the key science challenges pertaining to our understanding of extreme events. In addition, we present an overview of GICs including highlights of severe impacts over the last 80 years and recent U.S. Federal actions relevant to this community.

The geological and historical information on the magnitude and distribution of uplift and differential movements of rock masses as well as groundwater flow system transients that result from glacial unloading, erosion and tectonic stress have been reviewed. Data presented in the literature show that vertical crustal movements have occurred during the Cenozoic. In addition, the literature indicates significant transients exist in groundwater flow systems. The documented evidence of vertical crustal movements, plus supporting data on the stress-permeability constitutive relationships for discontinuities in fractured crystalline rocks, and three-dimensional modelling capability justifies a detailed analysis of the effects of vertical uplift on bedrock and on groundwater as they pertain to the deep disposal of radioactive waste. 159 annotated refs

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)

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.

The present dissertation is a cross-gender and cross-cultural sociophonetic exploration of voice pitch characteristics utilizing speech data derived from Japanese and American speakers in natural conversations. The roles of voice pitch modulation in terms of the concepts of politeness and emotion as they pertain to culture and gender will be investigated herein. The research interprets the significance of my findings based on the acoustic measurements of speech data as they are presented in the ERB-rate scale (the most appropriate scale for human speech perception). The investigation reveals that pitch range modulation displayed by Japanese informants in two types of conversations is closely linked to types of politeness adopted by those informants. The degree of the informants' emotional involvement and expressions reflected in differing pitch range widths plays an important role in determining the relationship between pitch range modulation and politeness. The study further correlates the Japanese cultural concept of enryo ("self-restraint") with this phenomenon. When median values were examined, male and female pitch ranges across cultures did not conspicuously differ. However, sporadically occurring women's pitch characteristics which culturally differ in width and height of pitch ranges may create an 'emotional' perception of women's speech style. The salience of these pitch characteristics appears to be the source of the stereotypically linked sound of women's speech being identified as 'swoopy' or 'shrill' and thus 'emotional'. Such women's salient voice characteristics are interpreted in light of camaraderie/positive politeness. Women's use of conspicuous paralinguistic features helps to create an atmosphere of camaraderie. These voice pitch characteristics promote the establishment of a sense of camaraderie since they act to emphasize such feelings as concern, support, and comfort towards addressees, Moreover, men's wide pitch ranges are discussed in view

Despite the widespread popularity of social media, little is known about the extent or context of pain-related posts by users of those media. The aim was to examine the type, context, and dissemination of pain-related tweets. We used content analysis of pain-related tweets from 50 cities to unobtrusively explore the meanings and patterns of communications about pain. Content was examined by location and time of day, as well as within the context of online social networks. The most common terms published in conjunction with the term "pain" included feel (n=1504), don't (n=702), and love (n=649). The proportion of tweets with positive sentiment ranged from 13% in Manila to 56% in Los Angeles, CA, with a median of 29% across cities. Temporally, the proportion of tweets with positive sentiment ranged from 24% at 1600 to 38% at 2400, with a median of 32%. The Twitter-based social networks pertaining to pain exhibited greater sparsity and lower connectedness than did those social networks pertaining to common terms such as apple, Manchester United, and Obama. The number of word clusters in proportion to node count was greater for emotion terms such as tired (0.45), happy (0.43), and sad (0.4) when compared with objective terms such as apple (0.26), Manchester United (0.14), and Obama (0.25). Taken together, our results suggest that pain-related tweets carry special characteristics reflecting unique content and their communication among tweeters. Further work will explore how geopolitical events and seasonal changes affect tweeters' perceptions of pain and how such perceptions may affect therapies for pain.

Full Text Available A well-educated workforce is essential to the infrastructure of a public health system. At the time when global focus on public health is increasing, a severe shortage of public health professionals is projected. A strong educational framework is imperative to ensure the capacity and capability of the worldwide public health workforce for the future. Frenk and Chen (2011 comment that academic public health has done far less than medicine or nursing to examine its pedagogy. The goal of this study is to examine the literature pertaining to the education of public health professionals in order to document the extent to which those preparing public health professionals think about what they teach, how they teach, and what the results of the instruction are. The specific objectives are to (1 identify relevant peer reviewed literature, (2 analyze that literature for content, (3 characterize the literature according to type of methodology, and (4 draw conclusions and implications to enhance future pedagogical efforts. The study searched three bibliographic sources for articles written in English between 2000-2012. The search of PubMed, Scopus, Education Full Text identified 576 unique articles. The articles were analyzed according to ten content themes and four format categories. The conclusions are that those teaching public health professionals devote considerable thought to what and how they teach, although original research and evaluation studies are fewer than descriptive reports of courses, programs and curricula. A journal devoted specifically to articles pertaining to education of public health professionals will encourage academicians to write articles sharing approaches to educating the public health workforce.

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.

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.

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 as fingerprints or face recognition) have been forcedly replaced by alternative biometric characteristics such as voice, as sometimes this is the only feature available. The present study benefits from the advances achieved during last years in understanding and modeling voice production. The paper hypothesizes that a gender-dependent characterization of speakers combined with the use of a set of features derived 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 the gender-dependent extended biometric parameters is 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. PMID:26442245
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.

Teachers suffer from voice problems more often than the rest of the population, as a consequence of the intensive use of their voices during teaching. Noise and classroom acoustics have been defined as hazards eventually leading to voice problems. In order to make a good classroom acoustic design...... to preserve the teachers’ voices and maximize their comfort, it is necessary to understand the underlaying relationship between classroom acoustics and teachers’ voice production. This paper presents a brief summary of investigations looking into this relationship. A pilot study, carried out in different...... located at various distances, in rooms with very different acoustics. A field study in schools of southern Sweden found out that teachers with and without voice problems, during actual teaching, are affected differently by the support of the classroom. A last laboratory experiment was carried out...

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.

Full Text Available This study assessed the within-subject variability of voice measures captured using different recording devices (i.e., smartphones and head mounted microphone and software programs (i.e., Analysis of Dysphonia in Speech and Voice (ADSV, Multi-dimensional Voice Program (MDVP, and Praat. Correlations between the software programs that calculated the voice measures were also analyzed. Results demonstrated no significant within-subject variability across devices and software and that some of the measures were highly correlated across software programs. The study suggests that certain smartphones may be appropriate to record daily voice measures representing the effects of vocal loading within individuals. In addition, even though different algorithms are used to compute voice measures across software programs, some of the programs and measures share a similar relationship.

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.

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.

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.

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.

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.

Natural hazards related to ground movement that directly affect the safety of motorists and highway infrastructure include, but are not limited to, rockfalls, rockslides, debris flows, and landslides. This thesis specifically deals with the evaluation of rockfall hazards through the evaluation of LiDAR data. Light Detection And Ranging (LiDAR) is an imaging technology that can be used to delineate and evaluate geomechanically-controlled hazards. LiDAR has been adopted to conduct hazard evaluations pertaining to rockfall, rock-avalanches, debris flows, and landslides. Characteristics of LiDAR surveying, such as rapid data acquisition rates, mobile data collection, and high data densities, pose problems to traditional CAD or GIS-based mapping methods. New analyses methods, including tools specifically oriented to geomechanical analyses, are needed. The research completed in this thesis supports development of new methods, including improved survey techniques, innovative software workflows, and processing algorithms to aid in the detection and evaluation of geomechanically controlled rockfall hazards. The scientific research conducted between the years of 2006-2010, as presented in this thesis, are divided into five chapters, each of which has been published by or is under review by an international journal. The five research foci are: (i) geomechanical feature extraction and analysis using LiDAR data in active mining environments; (ii) engineered monitoring of rockfall hazards along transportation corridors: using mobile terrestrial LiDAR; (iii) optimization of LiDAR scanning and processing for automated structural evaluation of discontinuities in rockmasses; (iv) location orientation bias when using static LiDAR data for geomechanical analysis; and (v) evaluating roadside rockmasses for rockfall hazards from LiDAR data: optimizing data collection and processing protocols.

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.

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.

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

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.
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.

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

The Internet is one of the most widely utilized resources for health-related information. Evaluation of the medical literature suggests that the quality and accuracy of these resources are poor and written at inappropriately high reading levels. The purpose of our study was to evaluate the quality, accuracy, and readability of online resources pertaining to hallux valgus. Two search terms ("hallux valgus" and "bunion") were entered into Google, Yahoo, and Bing. With the use of scoring criteria specific to hallux valgus, the quality and accuracy of online information related to hallux valgus was evaluated by 3 reviewers. The Flesch-Kincaid score was used to determine readability. Statistical analysis was performed with t tests and significance was determined by P values hallux valgus" (P = .045). Quality and accuracy were significantly higher in resources authored by physicians as compared to nonphysicians (quality, P = .04; accuracy, P hallux valgus is poor and written at inappropriate reading levels. Furthermore, the search term used, authorship, and presence of commercial bias influence the value of these materials. It is important for orthopaedic surgeons to become familiar with patient education materials, so that appropriate recommendations can be made regarding valuable resources.

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.

Full Text Available Self-recognition, being indispensable for successful social communication, has become a major focus in current social neuroscience. The physical aspects of the self are most typically manifested in the face and voice. Compared with the wealth of studies on self-face recognition, self-voice recognition (SVR has not gained much attention. Converging evidence has suggested that the fundamental frequency (F0 and formant structures serve as the key acoustic cues for other-voice recognition (OVR. However, little is known about which, and how, acoustic cues are utilized for SVR as opposed to OVR. To address this question, we independently manipulated the F0 and formant information of recorded voices and investigated their contributions to SVR and OVR. Japanese participants were presented with recorded vocal stimuli and were asked to identify the speaker—either themselves or one of their peers. Six groups of 5 peers of the same sex participated in the study. Under conditions where the formant information was fully preserved and where only the frequencies lower than the third formant (F3 were retained, accuracies of SVR deteriorated significantly with the modulation of the F0, and the results were comparable for OVR. By contrast, under a condition where only the frequencies higher than F3 were retained, the accuracy of SVR was significantly higher than that of OVR throughout the range of F0 modulations, and the F0 scarcely affected the accuracies of SVR and OVR. Our results indicate that while both F0 and formant information are involved in SVR, as well as in OVR, the advantage of SVR is manifested only when major formant information for speech intelligibility is absent. These findings imply the robustness of self-voice representation, possibly by virtue of auditory familiarity and other factors such as its association with motor/articulatory representation.

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.

Hearing voices (i.e. auditory verbal hallucinations) is mainly known as part of schizophrenia and other psychotic disorders. However, hearing voices is a symptom that can occur in many psychiatric, neurological and general medical conditions. We present three cases of non-psychotic patients with auditory verbal hallucinations caused by different disorders. The first patient is a 74-year-old male with voices due to hearing loss, the second is a 20-year-old woman with voices due to traumatisation. The third patient is a 27-year-old woman with voices caused by temporal lobe epilepsy. Hearing voices is a phenomenon that occurs in a variety of disorders. Therefore, identification of the underlying disorder is essential to indicate treatment. Improvement of coping with the voices can reduce their impact on a patient. Antipsychotic drugs are especially effective when hearing voices is accompanied by delusions or disorganization. When this is not the case, the efficacy of antipsychotic drugs will probably not outweigh the side-effects.

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.

Full Text Available While considered elusive and abstract, authorial voice is paramount in English writing. Unfortunately, many of Indonesian EFL learners found it is highly challeging to show their voice in their writing. The importance of voice is even exaggerated in argumentative writing, since this kind of writing needs obvious stance of the writer. This study investigates the authorial voice students made in their argumentative writing. The purpose of this study is to gain the picture of students‟ writing ability especially in authorial voice to map the road in guiding the next writing classes. The object of the study is the argumentative writing made by English department students at one Indonesian State College of Islamic Studies in their writing III course. Using Hyland‟s interactional model of voice (2008 the data analysis results the authorial presence in the essays is in position 2 at 0 – 4 scale which means the reader feels somehow weak presence of the authorial voice in the essay. This result confirms the findings of some previous studies that EFL learners especially from „interdependent‟ cultural background tend to find this authorial voice difficult in writing English essay.

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.

This study makes explicit the limitations and possibilities of voice-key naming latency research on single hiragana symbols (a Japanese syllabic script) by examining three sets of voice-key naming data against Sakuma, Fushimi, and Tatsumi's 1997 speech-analyzer voice-waveform data. Analysis showed that voice-key measurement errors can be substantial in standard procedures as they may conceal the true effects of significant variables involved in hiragana-naming behavior. While one can avoid voice-key measurement errors to some extent by applying Sakuma, et al.'s deltas and by excluding initial phonemes which induce measurement errors, such errors may be ignored when test items are words and other higher-level linguistic materials.

Voice loops, an auditory groupware technology, are essential coordination support tools for experienced practitioners in domains such as air traffic management, aircraft carrier operations and space shuttle mission control. They support synchronous communication on multiple channels among groups of people who are spatially distributed. In this paper, we suggest reasons for why the voice loop system is a successful medium for supporting coordination in space shuttle mission control based on over 130 hours of direct observation. Voice loops allow practitioners to listen in on relevant communications without disrupting their own activities or the activities of others. In addition, the voice loop system is structured around the mission control organization, and therefore directly supports the demands of the domain. By understanding how voice loops meet the particular demands of the mission control environment, insight can be gained for the design of groupware tools to support cooperative activity in other event-driven domains.

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

To evaluate voice of Iranian patients with Parkinson's disease (PD) and find any relationship between motor disabilities and acoustic voice parameters as speech motor components. We evaluated 27 Farsi-speaking PD patients and 21 age- and sex-matched healthy persons as control. Motor performance was assessed by the Unified Parkinson's Disease Rating Scale part III and Hoehn and Yahr rating scale in the "on" state. Acoustic voice evaluation, including fundamental frequency (f0), standard deviation of f0, minimum of f0, maximum of f0, shimmer, jitter, and harmonic to noise ratio, was done using the Praat software via /a/ prolongation. No difference was seen between the voice of the patients and the voice of the controls. f0 and its variation had a significant correlation with the duration of the disease, but did not have any relationships with the Unified Parkinson's Disease Rating Scale part III. Only limited relationship was observed between voice and motor disabilities. Tremor is an important main feature of PD that affects motor and phonation systems. Females had an older age at onset, more prolonged disease, and more severe motor disabilities (not statistically significant), but phonation disorders were more frequent in males and showed more relationship with severity of motor disabilities. Voice is affected by PD earlier than many other motor components and is more sensitive to disease progression. Tremor is the most effective part of PD that impacts voice. PD has more effect on voice of male versus female patients. Copyright Â© 2016 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

Full Text Available Student voice data is a key factor as Manchester Metropolitan University strives to continually improve institutional technology enhanced learning (TEL infrastructure. A bi-annual Institutional Student Survey enables students to communicate their experience of learning, teaching and assessment on programmes and specific units studied. Each cycle of the survey contains approximately 40–50,000 free text comments from students pertaining to what they appreciate and what they would like to see improved. A detailed thematic analysis of this data has identified 18 themes, arranged into six categories relating to the ‘Best’ aspects of courses, and 25 themes, arranged in seven categories in relation to aspects of courses considered to be ‘in need of improvement’. This student data was then used as a basis for semi-structured interviews with staff. Anecdotally, evidence suggested that student expectations and staff expectations around TEL and the virtual learning environment (VLE differed. On-going evaluation of this work has highlighted a disconnect. In significant instances, academic colleagues seemingly misinterpret the student voice analysis and consequently struggle to respond effectively. In response to the analysis, the learning technologist's role has been to re-interpret the analysis and redevelop TEL staff development and training activities. The changes implemented have focused on: contextualising resources in VLE; making lectures more interactive; enriching the curriculum with audio–visual resources; and setting expectations around communications.

The American Medical Association (AMA) and National Institutes of Health (NIH) recommend that patient education materials be written at no higher than a sixth-grade reading level. We examined 100 online educational materials for the 10 hand conditions most commonly treated by hand surgeons, as reported by the American Society for Surgery of the Hand. The listed conditions were carpal tunnel syndrome, basal joint arthritis of the thumb, de Quervain syndrome, Dupuytren's contracture, ganglion cysts, hand fractures, trigger finger, extensor tendon injuries, flexor tendon injuries, and mallet finger. Following a Google search for each condition, we analyzed the 10 most visited websites for each disorder utilizing the Flesch-Kincaid formula. The average grade reading level of the 100 websites studied was 9.49 with a reading ease of 53.03 ("fairly difficult high school"). Only 29% of the websites were at or below the national average of an eighth-grade reading level. Carpal tunnel syndrome had the highest average grade reading level at 10.32 (standard deviation: 1.52), whereas hand fractures had the lowest at 8.14 (2.03). Every hand condition in this study had an average readability at or above the ninth-grade reading level. The most frequently accessed materials for common maladies of the hand exceed both the readability limits recommended by the AMA and NIH, and the average reading ability of most US adults. Therefore, the most commonly accessed websites pertaining to hand pathology may not be comprehended by the audience for which it is intended.
Full Text Available Abstract Background Examination of consultation data in a variety of primary care settings in Tanzania shows that, while psychoses are routinely diagnosed and treated at primary care level, depression is rarely recorded as a reason for consultation. Since, epidemiological studies elswhere show that depression is a much more common disorder than psychosis, a series of studies were undertaken to elucidate this apparent paradox in Tanzania and inform mental health policy; firstly, a household prevalence study to ascertain the prevalence of common mental disorders at community level in Tanzania; secondly, a study to ascertain the prevalence of common mental disorders in primary care attenders; and thirdly, a study to ascertain the current status of the knowledge, attitude and practice pertaining to depression among primary health care workers. This paper reports the findings of the latter study. Methods All the primary health care workers (N = 14 in four primary health care centres in Tanzania were asked to complete the Depression Attitude Questionnaire, which assesses the health worker's knowledge and attitude towards the causes, consequences and treatment of depression. Results The majority of respondents felt that rates of depression had increased in recent years, believed that life events were important in the aetiology of depression, and generally held positive views about pharmacological and psychological treatments of depression, prognosis and their own involvement in the treatment of depressed patients. However, the majority of respondents felt that becoming depressed is a way that people with poor stamina deal with life difficulties. Conclusion The findings suggest a need to strengthen the training of primary health care workers in Tanzania about the detection of depression, pharmacological and psychological treatments, and psychosocial interventions.

Methods All the primary health care workers (N = 14) in four primary health care centres in Tanzania were asked to complete the Depression Attitude Questionnaire, which assesses the health worker's knowledge and attitude towards the causes, consequences and treatment of depression. Results The majority of respondents felt that rates of depression had increased in recent years, believed that life events were important in the aetiology of depression, and generally held positive views about pharmacological and psychological treatments of depression, prognosis and their own involvement in the treatment of depressed patients. However, the majority of respondents felt that becoming depressed is a way that people with poor stamina deal with life difficulties. Conclusion The findings suggest a need to strengthen the training of primary health care workers in Tanzania about the detection of depression, pharmacological and psychological treatments, and psychosocial interventions.

Porous silicates containing dilute amounts of tri-, tetra- and penta-valent metal sites, such as TS-1, Sn-β and Fe-ZSM-5, have recently emerged as state of the art catalysts for a variety of sustainable chemical transformations. In contrast with their aluminosilicate cousins, which are widely employed throughout the refinery industry for gas-phase catalytic transformations, such metallosilicates have exhibited unprecedented levels of performance for a variety of liquid-phase catalytic processes, including the conversion of biomass to chemicals, and sustainable oxidation technologies with H2O2. However, despite their unique levels of performance for these new types of chemical transformations, increased utilization of these promising materials is complicated by several factors. For example, their utilization in a liquid, and often polar, medium hinders process intensification (scale-up, catalyst deactivation). Moreover, such materials do not generally exhibit the active-site homogeneity of conventional aluminosilicates, and they typically possess a wide variety of active-site ensembles, only some of which may be directly involved in the catalytic chemistry of interest. Consequently, mechanistic understanding of these catalysts remains relatively low, and competitive reactions are commonly observed. Accordingly, unified approaches towards developing more active, selective and stable porous metallosilicates have not yet been achieved. Drawing on some of the most recent literature in the field, the purpose of this mini review is both to highlight the breakthroughs made with regard to the use of porous metallosilicates as heterogeneous catalysts for liquid-phase processing, and to highlight the pertaining challenges that we, and others, aim to overcome during the forthcoming years.

The myriad of cells in the human body are all made from the same blueprint: the human genome. At the heart of this diversity lies the concept of gene regulation, the process in which it is decided which genes are used where and when. Genes do not function as on/off buttons, but more like a volume...... mostly near the start of the gene known as the promoter. This region contains patterns scattered in the DNA that the TFs can recognize and bind to. Such binding can prompt the assembly of the pre-initiation complex which ultimately leads to transcription of the gene. In order to achieve the regulation...... on what characterizes a hippocampus promoter. Pairing CAGE with TF binding site prediction we identi¿ed a likely key regulator of hippocampus.

Full Text Available What follows is a case study of a freshman at Millersville University who shall be referred to under the pseudonym “Root Beer,” who is enrolled in her first semester in the Spring semester of the 2010-2011 academic year. This case study began with an inquiry-based approach which was applied by presenting the student with a survey of questions which would help to identify the student, her background, and the various characteristics of her writing. This inquiry-based approach was utilized throughout the case study to address the puzzles of practice that came up during the course of determining this student’s needs as a writer. As the research process continued, the center of gravity for this student was identified as voice. Utilizing the knowledge gained about the writer, this researcher was able to provide materials that were selected based on the writer’s profile as a unique individual, in order to provide a familiar foundation to the student writer Root Beer as she worked through the difficulty of expressing voice in her writing. This case study with Root Beer was completed over the course of five separate one-on-one meetings with the student outside of class, each of which was at least one hour in length, although at least one meeting with the student ran two hours in length. This case study also included five observations of Root Beer’s English Composition class with Dr. Shea, conducted in Byerly Hall, Room 120, from 9 AM – 10:15 AM, Tuesdays and Thursdays. This case study will include a detailed explanation of the exercises employed to address the center of gravity issue of voice, the reasoning behind the selection of these exercises, an analysis the results, and how these results were employed in the selection of successive exercises. The potential implications and possible future applications of these exercises toward addressing this issue within a classroom of student writers in the future will also be expounded on in the
Full Text Available Voice-induced synaesthesia, a form of synaesthesia in which synaesthetic perceptions are induced by the sounds of people’s voices, appears to be relatively rare and has not been systematically studied. In this study we investigated the synaesthetic colour and visual texture perceptions experienced in response to different types of voice quality (e.g. nasal, whisper, falsetto. Experiences of three different groups – self-reported voice synaesthetes, phoneticians and controls – were compared using both qualitative and quantitative analysis in a study conducted online. Whilst, in the qualitative analysis, synaesthetes used more colour and texture terms to describe voices than either phoneticians or controls, only weak differences, and many similarities, between groups were found in the quantitative analysis. Notable consistent results between groups were the matching of higher speech fundamental frequencies with lighter and redder colours, the matching of whispery voices with smoke-like textures and the matching of harsh and creaky voices with textures resembling dry cracked soil. These data are discussed in the light of current thinking about definitions and categorizations of synaesthesia, especially in cases where individuals apparently have a range of different synaesthetic inducers.
Full Text Available Despite the expanded use of the Internet for language learning and practice, little attention if any has been given to the quality of interaction among English L2 speakers in conversational text or voice chat rooms. This study explored the patterns of repair moves in synchronous non-native speaker (NNS text chat rooms in comparison to voice chat rooms on the Internet. The following questions were posed: (a Which types of repair moves occur in text and voice chats; and (b what are the differences, if any, between the repair moves in text chats and voice chats when time is held constant? Repair moves made by anonymous NNSs in 10, 5-minute, synchronous chat room sessions (5 text-chat sessions, 5 voice-chat sessions were counted and analyzed using chi-square with alpha set at .05. Significant differences were found between the higher number of total repair moves made in voice chats and the smaller number in text chats. Qualitative data analysis showed that repair work in voice chats was often pronunciation-related. The study includes discussion that may affect teachers' and learners' considerations of the value of NNS chat room interaction for second language development.

Voice-induced synesthesia, a form of synesthesia in which synesthetic perceptions are induced by the sounds of people's voices, appears to be relatively rare and has not been systematically studied. In this study we investigated the synesthetic color and visual texture perceptions experienced in response to different types of “voice quality” (e.g., nasal, whisper, falsetto). Experiences of three different groups—self-reported voice synesthetes, phoneticians, and controls—were compared using both qualitative and quantitative analysis in a study conducted online. Whilst, in the qualitative analysis, synesthetes used more color and texture terms to describe voices than either phoneticians or controls, only weak differences, and many similarities, between groups were found in the quantitative analysis. Notable consistent results between groups were the matching of higher speech fundamental frequencies with lighter and redder colors, the matching of “whispery” voices with smoke-like textures, and the matching of “harsh” and “creaky” voices with textures resembling dry cracked soil. These data are discussed in the light of current thinking about definitions and categorizations of synesthesia, especially in cases where individuals apparently have a range of different synesthetic inducers.

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.

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.

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.

The paper deals with the increasing accuracy of voice authentication methods. The developed algorithm first extracts segmental parameters, such as Zero Crossing Rate, the Fundamental Frequency and Mel-frequency cepstral coefficients from voice. Based on these parameters, the neural network classifier detects the speaker's emotional state. These parameters shape the distribution of neurons in Kohonen maps, forming clusters of neurons on the map characterizing a particular emotional state. Using regression analysis, we can calculate the function of the parameters of individual emotional states. This relationship increases voice authentication accuracy and prevents unjust rejection.

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

Cystic fibrosis is a common autosomal recessive disorder with drastic respiratory symptoms, including shortness of breath and chronic cough. While most of cystic fibrosis treatment is dedicated to mitigating the effects of respiratory dysfunction, the potential effects of this disease on vocal parameters have not been systematically studied. We hypothesized that cystic fibrosis patients, given their characteristic respiratory disorders, would also present dysphonic symptoms. Given that voice disorders can severely impair quality of life, the identification of a potential cystic fibrosis-related dysphonia could be of great value for the clinical evaluation and treatment of this disease. We tested our hypothesis by measuring vocal parameters, using both objective physical measures and the GRBAS subjective evaluation method, in male and female cystic fibrosis patients undergoing conventional treatment and compared them to age and sex matched controls. We found that cystic fibrosis patients had a significantly lower vocal intensity and harmonic to noise ratio, as well as increased levels of jitter and shimmer. In addition, cystic fibrosis patients also showed higher scores of roughness, breathiness and asthenia, as well as a significantly altered general grade of dysphonia. When we segregated the results according to sex, we observed that, as a group, only female cystic fibrosis patients had significantly lower values of harmonic to noise ratio and an abnormal general grade of dysphonia in relation to matched controls, suggesting that cystic fibrosis exerts a more pronounced effect on vocal parameters of women in relation to men. Overall, the dysphonic characteristics of CF patients can be explained by dysfunctions in vocal fold movement and partial upper airway obstruction, potentially caused by the accumulation of mucus and chronic cough characteristic of CF symptomatology. Our results show that CF patients exhibit significant dysphonia and suggest they may

This article is a compilation of own research performed during the European COoperation in Science and Technology (COST) action 2103: 'Advance Voice Function Assessment', an initiative of voice and speech processing teams consisting of physicists, engineers, and clinicians. This manuscript concerns analyzing largely irregular voicing types, namely substitution voicing (SV) and adductor spasmodic dysphonia (AdSD). A specific perceptual rating scale (IINFVo) was developed, and the Auditory Model Based Pitch Extractor (AMPEX), a piece of software that automatically analyses running speech and generates pitch values in background noise, was applied. The IINFVo perceptual rating scale has been shown to be useful in evaluating SV. The analysis of strongly irregular voices stimulated a modification of the European Laryngological Society's assessment protocol which was originally designed for the common types of (less severe) dysphonia. Acoustic analysis with AMPEX demonstrates that the most informative features are, for SV, the voicing-related acoustic features and, for AdSD, the perturbation measures. Poor correlations between self-assessment and acoustic and perceptual dimensions in the assessment of highly irregular voices argue for a multidimensional approach.

This study aimed to compare musculoskeletal pain perception in teachers with voice disorders and in those with healthy voices, and to investigate the relationship between musculoskeletal pain and occupational variables (ie, work journey per week and working period). Forty-three classroom teachers were divided into two groups: dysphonic group (DG), 32 classroom teachers with voice complaints and voice disorders; and non-DG, 11 classroom teachers without voice complaints and who are vocally healthy. The musculoskeletal pain investigation survey was used to investigate the frequency and intensity of the pain. Occupational variables, such as work journey per week and working period, were investigated by the Voice Production Condition-Teacher questionnaire. The statistical tests used were the Spearman correlation (P ≤ 0.05) and the Mann-Whitney U test (P ≤ 0.05). There was no difference between the frequency and the intensity of musculoskeletal pain regarding dysphonia. Work journey per week was positively related to the frequency and the intensity of laryngeal pain in the DG. The working period had a negative relationship to the frequency and the intensity of musculoskeletal pain in the submandibular region in the DG. Classroom teachers with voice disorders and those with healthy voices do not have differences regarding the frequency and the intensity of musculoskeletal pain. Besides dysphonia the pain is an important symptom to be considered in classroom teachers. The occupational variables contributed to the presence of musculoskeletal pain in the region near the larynx, which appears to be directly proportional to work journey per week and inversely proportional to the working period.

Human Biological Materials (HBMs) are an invaluable resource in biomedical research. To determine if researchers and a Research Ethics Committee (REC) at a South African institution addressed ethical issues pertaining to HBMs in collaborative research with developed countries. Ethically approved retrospective cross-sectional descriptive audit. Of the 1305 protocols audited, 151 (11.57%) fulfilled the study's inclusion criteria. Compared to other developed countries, a majority of sponsors (90) were from the USA (p = 0.0001). The principle investigators (PIs) in all 151 protocols informed the REC of their intent to store HBMs. Only 132 protocols informed research participants (P ethical and regulatory issues pertaining to HBMs. There was a lack of congruence between the ethical guidelines of developed countries and their actions which are central to the access to HBMs in collaborative research. HBMs may be leaving South Africa without EPs and MTAs during the process of international collaborative research. © 2013 John Wiley & Sons Ltd.

This cross-sectional study aimed to assess the knowledge, attitude and anxiety pertaining to basic life support (BLS) and medical emergencies among interns in dental colleges of Mangalore city, Karnataka, India. The study subjects comprised of interns who volunteered from the four dental colleges. The knowledge and attitude of interns were assessed using a 30-item questionnaire prepared based on the Basic Life Support Manual from American Heart Association and the anxiety of interns pertaining to BLS and medical emergencies were assessed using a State-Trait Anxiety Inventory (STAI) Questionnaire. Chi-square test was performed on SPSS 21.0 (IBM Statistics, 2012) to determine statistically significant differences ( P <0.05) between assessed knowledge and anxiety. Out of 183 interns, 39.89% had below average knowledge. A total of 123 (67.21%) reported unavailability of professional training. The majority (180, 98.36%) felt the urgent need of training in basic life support procedures. Assessment of stress showed a total of 27.1% participants to be above high-stress level. Comparison of assessed knowledge and stress was found to be insignificant ( P =0.983). There was an evident lack of knowledge pertaining to the management of medical emergencies among the interns. As oral health care providers moving out to the society, a focus should be placed on the training of dental interns with respect to Basic Life Support procedures.

define the beginning of the Brunhes Chron and helps constrain the Brunhes-Matuyama boundary. The Bishop ash, which was dispersed as far east as Nebraska, Kansas, and Texas, provides an important tephrostratigraphic marker throughout the Western United States. The obsidian domes of both the Mono and Inyo Craters, which were produced by rhyolitic eruptions in the past 40,000 years, have been well studied, including extensive scientific drilling through the domes. Exploratory drilling to 3-km depth on the resurgent dome and subsequent instrumentation of the Long Valley Exploratory Well (LVEW) have led to a number of important new insights. Scientific drilling also has been done within the Casa Diablo geothermal field, which, aside from drilling, has been commercially developed and is currently feeding 40 MW of power into the Southern California Edison grid. Studies in all the above-mentioned volcanic fields have contributed to the extensive scientific literature published on the Long Valley region. Although most of this scientific literature has been published since 1970, a significant amount of historical literature extends backward to the late 1800s. The purpose of this bibliography is to compile references pertaining to the Long Valley region from all time periods and all Earth science fields into a single listing, thus providing an easily accessible guide to the published literature for current and future researchers.

Full Text Available This paper studies the concept of form of life as central to ordinary language philosophy (as understood in Wittgenstein’s, Austin’s and Stanley Cavell’s work: philosophy of our language as spoken; pronounced by a human voice within a form of life. Such an approach to Wittgenstein’s later philosophy shifts the question of the common use of language – central to Wittgenstein’s Investigations – to the definition of the subject as voice, and to the reinvention of subjectivity in language. The voice is both a subjective and common expression: it is what makes it possible for my individual voice, or claim, to become shared and for our forms of life to be intertwined with a lifeform.

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.

This study demonstrates success of a voice simulation experience during orientation in changing the biases of nursing students and the effect on the development of the nurse-patient relationship. Ninety-four individuals participated; 52 received a voice simulation experience during orientation, and 42 received orientation with no voice simulation experience. The Medical Condition Regard Scale was administered before and after orientation. Posttest paired t test results show significant differences in attitudes toward patients with voice hearing experiences between the two groups. The themes of personal growth from the focus groups postorientation include Affective Experience, Physical Experience, and Empathy. Findings demonstrate that the orientation process should include methods to challenge stereotyping and bias to decrease stigma, improve service access, and enhance the ability to develop therapeutic relationships.

Transcript Structure and Domain Display (TSDD) is a publicly available, web-based program that provides publication quality images of transcript structures and domains. TSDD is capable of producing transcript structures from GFF/GFF3 and BED files. Alternatively, the GFF files of several model organisms have been pre-loaded so that users only needs to enter the locus IDs of the transcripts to be displayed. Visualization of transcripts provides many benefits to researchers, ranging from evolutionary analysis of DNA-binding domains to predictive function modeling. TSDD is freely available for non-commercial users at http://shenlab.sols.unlv.edu/shenlab/software/TSD/transcript_display.html : firstname.lastname@example.org. © The Author 2016.

Full Text Available In this paper the authors refer to the voice as expressive sphere of communication between two people. The voice expresses a symbolic meaning whose function is to represent our feelings, and thus our emotional life.The emission of sounds weaves an unconscious communication of affection, expresses the archaic nature of the links between body and language, the presence of a strong sensorial auditory, olfactory, tactile and visual.

Gender is salient, socially critical information obtained from faces and voices, yet the brain processes underlying gender discrimination have not been well studied. We investigated neural correlates of gender processing of voices in two ERP studies. In the first, ERP differences were seen between female and male voices starting at 87 ms, in both spatial-temporal and peak analyses, particularly the fronto-central N1 and P2. As pitch differences may drive gender differences, the second study used normal, high- and low-pitch voices. The results of these studies suggested that differences in pitch produced early effects (27-63 ms). Gender effects were seen on N1 (120 ms) with implicit pitch processing (study 1), but were not seen with manipulations of pitch (study 2), demonstrating that N1 was modulated by attention. P2 (between 170 and 230 ms) discriminated male from female voices, independent of pitch. Thus, these data show that there are two stages in voice gender processing; a very early pitch or frequency discrimination and a later more accurate determination of gender at the P2 latency.
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.

To investigate the application and significance of aerodynamic parameters in voice function assessment. The phonatory aerodynamic system (PAS) was used to collect aerodynamic parameters from subjects with normal voice, vocal fold polyp, vocal fold cyst, and vocal fold immobility. Multivariate statistical analysis was used to compare measurements across groups. Phonation threshold flow (PTF), mean flow rate (MFR), maximum phonation time (MPT), and glottal resistance (GR) in one hundred normal subjects were significantly affected by sex (P efficiency (VE) were not (P > 0.05). PTP, PTF, MFR, SGP, and MPT were significantly different between normal voice and voice disorders (P 0.05). Receiver operating characteristic (ROC) analysis found that PTP, PTF, SGP, MFR, MPT, and VE in one hundred thirteen voice dis orders had similar diagnostic utility (P aerodynamic parameters of the three degrees of voice dysfunction due to vocal cord polyps were compared and found to have no significant differences (P > 0.05). PTP, PTF, MFR, SGP and MPT in forty one patients with vocal polyps were significantly different after surgical resection of vocal cord polyps (P aerodynamic parameters can objectively and effectively evaluate the variations of vocal function, and have good auxiliary diagnostic value.
Full Text Available In positioning student voice within the Irish education policy discourse it is imperative that this emergent and complex concept is explored and theorized in the context of its definition and motivation. Student voice can then be positioned and critiqued as it emerged within Irish education policy primarily following Ireland’s ratification of the United Nations Charter on the Rights of the Child (UNCRC in 1992. Initially emerging in policy from a rights-based and democratic citizenship perspective, the student council became the principal construct for student voice in Irish post-primary schools. While central to the policy discourse, the student council construct has become tokenistic and redundant in practice. School evaluation policy, both external and internal, became a further catalyst for student voice in Ireland. Both processes further challenge and contest the motivation for student voice and point to the concept as an instrument for school improvement and performativity that lacks any centrality for a person-centered, rights-based, dialogic and consultative student voice within an inclusive classroom and school culture.
Like other areas of speech-language pathology, the behavioural management of voice disorders lacks precision regarding optimal dose-response relationships. In voice therapy, dosing can presumably vary from no measurable effect (i.e., no observable benefit or adverse effect), to ideal dose (maximum benefit with no adverse effects), to doses that produce toxic or harmful effects on voice production. Practicing specific vocal exercises will inevitably increase vocal load. At ideal doses, these exercises may be non-toxic and beneficial, while at intermediate or high doses, the same exercises may actually be toxic or damaging to vocal fold tissues. In pharmacology, toxicity is a critical concept, yet it is rarely considered in voice therapy, with little known regarding "effective" concentrations of specific voice therapies vs "toxic" concentrations. The potential for vocal fold tissue damage related to overdosing on specific vocal exercises has been under-studied. In this commentary, the issue of dosing will be explored within the context of voice therapy, with particular emphasis placed on possible "overdosing".

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.

To correlate self-reporting of voice disorders with habits that impact voice production and situations of violence experienced by teachers. The study involved 41 elementary-school teachers of rural and urban areas. Two instruments were used for data collection: The Vocal Production Condition - Teacher (CPV-P) questionnaire and the Screening Index for Voice Disorders - ITDV. The chi-square test was used to verify association among variables with a significance level of 5%. The sample consisted of 8 men and 33 women aged 25-66 years with a median of 39 years. Regarding vocal habits, 33 people (80.5%) mentioned the screaming as usual practice, 40 people (97.5%) declared they talk a lot. As for voice care, 31 people (73.1%) reported drinking water while using their voice. As for the ITDV total score, 30 teachers (73.1%) were above the score threshold set for predisposition to vocal disorders. Statistical analysis revealed a significant association between female participants and complaint of graffiti writings as a type of violence. No significant correlation between the ITDV results with gender and the ITDV with forms of violence evaluated in the study was indicated. Self-reporting of voice disorders showed no significant relationship with acts of violence. However, analysis of the context of violence in schools and vocal problems are issues worthy of attention, particularly the observed naturalization of gender inssues, which is seldom problematized.

Voice hearing experiences, or auditory verbal hallucinations, occur in healthy individuals as well as in individuals who need clinical care, but news media depict voice hearing primarily as a symptom of mental illness, particularly schizophrenia. This article explores whether, and how, public perception of an exaggerated association between voice hearing and mental illness might influence individuals' need for clinical care. A narrative literature review was conducted, using relevant peer-reviewed research published in the English language. Stigma may prevent disclosure of voice hearing experiences. Non-disclosure can prevent access to sources of normalizing information and lead to isolation, loss of social support and distress. Internalization of stigma and concomitantly decreased self-esteem could potentially affect features of voices such as perceived voice power, controllability, negativity and frequency, as well as distress. Increased distress may result in a decrease in functioning and increased need for clinical care. The literature reviewed suggests that stigma has the potential to increase need for care through many interrelated pathways. However, the ability to draw definitive conclusions was constrained by the designs of the studies reviewed. Further research is needed to confirm the findings of this review.

Chromatin is a complex assembly that compacts DNA inside the nucleus while providing the necessary level of accessibility to regulatory factors conscripted by cellular signaling systems. In this superstructure, DNA is the subject of mechanical forces applied by variety of molecular motors. Rather than being a rigid stick, DNA possesses dynamic structural variability that could be harnessed during critical steps of genome functioning. The strong relationship between DNA structure and key genomic processes necessitates the study of physical constrains acting on the double helix. Here we provide insight into the source, dynamics, and biology of DNA topological domains in the eukaryotic cells and summarize their possible involvement in gene transcription. We emphasize recent studies that might inspire and impact future experiments on the involvement of DNA topology in cellular functions. PMID:24755522

Using data from a five-year online survey the paper examines the effects of relative satisfaction with health services on individuals' voice-and-choice activity in the English public health care system. Voice is considered in three parts – individual voice (complaints), collective voice voting and participation (collective action). Exercising choice is seen in terms of complete exit (not using health care), internal exit (choosing another public service provider) and private exit (using private health care). The interaction of satisfaction and forms of voice and choice are analysed over time. Both voice and choice are correlated with dissatisfaction with those who are unhappy with the NHS more likely to privately voice and to plan to take up private health care. Those unable to choose private provision are likely to use private voice. These factors are not affected by items associated with social capital – indeed, being more trusting leads to lower voice activity.

This randomized trial investigated voice rest and supplemental text-to-speech communication versus voice rest alone on visual analog scale measures of communication effectiveness and magnitude of voice use. Randomized clinical trial. Multicenter outpatient voice clinics. Thirty-seven patients undergoing phonomicrosurgery. Patients undergoing phonomicrosurgery were randomized to voice rest and supplemental text-to-speech communication or voice rest alone. The primary outcome measure was the impact of voice rest on ability to communicate effectively over a 7-day period. Pre- and postoperative magnitude of voice use was also measured as an observational outcome. Patients randomized to voice rest and supplemental text-to-speech communication reported higher median communication effectiveness on each postoperative day compared to those randomized to voice rest alone, with significantly higher median communication effectiveness on postoperative days 3 (P=.03) and 5 (P=.01). Magnitude of voice use did not differ on any preoperative (P>.05) or postoperative day (P>.05), nor did patients significantly decrease voice use as the surgery date approached (P>.05). However, there was a significant reduction in median voice use pre- to postoperatively across patients (Pcommunication increased patient-perceived communication effectiveness on postoperative days 3 and 5 over voice rest alone. With the prevalence of smartphones and the widespread use of text messaging, supplemental text-to-speech communication may provide an accessible and cost-effective communication option for patients on vocal restrictions. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Background and purpose: In the majority of patients irradiated for early glottic cancer an abnormal voice was reported. The purpose of the study was to determine the factors influencing voice quality after radiotherapy for T1 glottic cancer. Methods: The voices of 75 male patients irradiated for T1 glottic carcinoma were assessed subjectively and objectively by acoustic analyses and aerodynamic measurements. The laryngeal function and morphology were evaluated by videolaryngostroboscopy. The data on smoking habits, the associated diseases influencing voice quality, the extent of the tumor, the type of biopsy, and the irradiation technique were collected from the medical records. The data on the factors influencing voice quality were compared for patients with a normal/near-normal voice and those with a hoarse voice. Results: Voice quality was at least slightly abnormal in 94.7% and 81.3% of patients, when assessed perceptively and objectively, respectively. Smoking after the completed treatment, more severe morphologic alterations of the vocal folds, dryness of the throat, incomplete closure of the vocal folds and functional voice disorders expressed as supraglottic activity adversely influenced the voice quality. A good correlation between the perceptive voice assessment and the acoustic analyses was established. Conclusions: After the successful irradiation for T1 glottic carcinoma, the great majority of the patients have at least a slightly hoarse voice. A better voice outcome could be achieved if radiotherapy was followed by the patient's cessation of smoking and the appropriate voice therapy.

The aim was to investigate the effects of glottal stop productions (GS) on voice in children with cleft palate using multidimensional voice assessment methods. This is a prospective case-control study. Children with repaired cleft palate (n = 34) who did not have any vocal fold lesions were separated into two groups based on the results of the articulation test. The glottal stop group (GSG) consisted of 17 children who had GS. The control group (CG) consisted of an equal number of age- and gender-matched children who did not have GS. The voice evaluation protocol included acoustic analysis, Pediatric Voice Handicap Index (pVHI), and perceptual analysis (Grade, Roughness, Breathiness, Asthenia, Strain method). The velopharyngeal statuses of the groups were compared using the nasopharyngoscopy and the nasometer. The total pVHI score and the subscales of the pVHI were found to be significantly higher in the GSG. The F0, jitter, and shimmer were found to be numerically higher in the GSG with the difference being statistically significant in jitter (P speech and language pathology intervention including voice therapy techniques.

This study aimed to explore psychosocial factors contributing to the development of functional voice disorders (FVD) and those differentiating between organic voice disorders (OVD) and a non-voice-disordered control group. A case-control study was undertaken of 194 women aged 18-80 years diagnosed with FVD (n = 73), OVD (n = 55), and controls (n = 66). FVD women were allocated into psychogenic voice disorder (PVD) (n = 37) and muscle tension voice disorder (MTVD) (n = 36) for sub-group analysis. Dependent variables included biographical and voice assessment data, the number and severity of life events and difficulties and conflict over speaking out (COSO) situations derived from the Life Events and Difficulties Schedule (LEDS), and psychological traits including emotional expressiveness scales. Four psychosocial components differentiated between the FVD and control group accounting for 84.9% of the variance: severe events, moderate events, severe COSO, and mild COSO difficulties. Severe events, severe and mild COSO difficulties differentiated between FVD and OVD groups, accounting for 80.5% of the variance. Moderate events differentiated between PVD and MTVD sub-groups, accounting for 58.9% of the variance. Psychological traits did not differentiate between groups. Stressful life events and COSO situations best differentiated FVD from OVD and control groups. More refined aetiological studies are needed to differentiate between PVD and MTVD.

Full Text Available Abstract Background Little has been reported about the impact of tracheoesophageal (TE speech on individuals in the Middle East where the procedure has been gaining in popularity. After total laryngectomy, individuals in Europe and North America have rated their quality of life as being lower than non-laryngectomized individuals. The purpose of this study was to evaluate changes in quality of life and degree of voice handicap reported by laryngectomized speakers from Jordan before and after establishment of TE speech. Methods Twelve male Jordanian laryngectomees completed the University of Michigan Head & Neck Quality of Life instrument and the Voice Handicap Index pre- and post-TE puncture. Results All subjects showed significant improvements in their quality of life following successful prosthetic voice restoration. In addition, voice handicap scores were significantly reduced from pre- to post-TE puncture. Conclusion Tracheoesophageal speech significantly improved the quality of life and limited the voice handicap imposed by total laryngectomy. This method of voice restoration has been used for a number of years in other countries and now appears to be a viable alternative within Jordan.

Full Text Available Nowadays, speech technologies are among the most vibrant sectors of the world’s economy. Of high importance is the problem of ensuring the security of speech information (SI. Here we discuss SI protection systems within a modern communication model. The model is multimodal, multithreaded, and implies a large number of subscribers interacting via several communication lines. With this in mind, we perform a detailed analysis of threats to the confidentiality, integrity and accessibility of SI. Existing methods of counteraction against these threats are discussed, and shown to be insufficient to ensure the safety of voice messages (VM in full. Mean while, there are new threats to the integrity and accessibility of SI, the solutions for which are either do not exist, or only being developed. We propose our original approach to counter these threats. Steganography methods are the most promising for ensuring the integrity of the VM. In particular, using audiomarkers allows one to reliably trace speaker’sidentity throughout the entire communication session. In order to counter the threats to SI availability due to the capacity of the communication channel and the limited volumes of VM data storage, it is necessary to improve existing adaptive speech compression algorithms, along with developing new ones. Furthermore, such algorithms must keep the specified level of speech intelligibility.

Full Text Available Murga is, in its simplest terms, popular musical theater of Uruguayan Carnival, but in reality it is much more than this. It is theater, music, identity, myth, political criticism; it is the voice of the people. The murga is a group of popular musical theater whose members sing and act on various tablados –neighborhood makeshift stages– and it is the most political component of Uruguayan Carnival. The murga criticizes, satirizes and questions society, politicians and situations constantly, but it never defines itself as political nor theoretical. It is simply a form of popular art. It is a way to take the issues, which affect everyone, to the masses, to the tablados which are filled every night of Carnaval. During the dictatorship, which brought with it censorship of every sort, murgas were censored just like all artistic endeavors. However, murgas were able to subvert the censorship of their lyrics, permitting them to criticize the outrages and crimes of the government with the music itself. Although the political situation has now changed dramatically, the murga is still a necessary element of Uruguayan socio-political discourse. This article aims to summarize the history of Carnival in Uruguay and specifically the murga, as well as to analyze song lyrics from historically important shows from two different eras.

Vocal education programs for teachers may prevent the emergence of vocal disorders; however, only a few studies have tried to evaluate the effectiveness of these preventive programs, particularly in the long term. Two hundred and sixty-four subjects, mostly kindergarten and primary school female teachers, participated in a course on voice care, including a theoretical seminar (120 minutes) and a short voice group therapy (180 minutes, small groups of 20 subjects). For 3 months, they had to either attend the vocal ergonomics norms and, as psychological reinforcement, they had to make out a daily report of vocal abuse, or to follow the given exercises for a more efficient vocal technique, reporting on whether the time scheduled was respected or not. The effectiveness of the course was assessed in a group of 21 female teachers through a randomized controlled study. Evaluation comprehended stroboscopy, perceptual and electro-acoustical voice analysis, Voice Handicap Index, and a course benefit questionnaire. A group of 20 teachers matched for age, working years, hoarseness grade, and vocal demand served as a control group. At 3 months evaluation, participants demonstrated amelioration in the global dysphonia rates (P=0.0003), jitter (P=0.0001), shimmer (P=0.0001), MPT (P=0.0001), and VHI (P=0.0001). Twelve months after the course, the positive effects remained, although they were slightly reduced. In conclusion, a course inclusive of two lectures, a short group voice therapy, home-controlled voice exercises, and hygiene, represents a feasible and cost-effective primary prevention of voice disorders in a homogeneous and well-motivated population of teachers.
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.
Full Text Available The article deals with interrelations of voice, body and technology in popular music from a musicological perspective. It is an attempt to outline a systematic approach to the history of music technology with regard to aesthetic aspects, taking the identity of the singing subject as a main point of departure for a hermeneutic reading of popular song. Although the argumentation is based largely on musicological research, it is also inspired by the notion of presentness as developed by theologian and media scholar Walter Ong. The variety of the relationships between voice, body, and technology with regard to musical representations of identity, in particular gender and race, is systematized alongside the following cagories: (1 the “absence of the body,” that starts with the establishment of phonography; (2 “amplified presence,” as a signifier for uses of the microphone to enhance low sounds in certain manners; and (3 “hybridity,” including vocal identities that blend human body sounds and technological processing, whereby special focus is laid on uses of the vocoder and similar technologies.

Rehabilitation of voice and speech after total laryngectomy has become established practice in recent years. A voice prosthesis is placed within a surgically produced fistula between the trachea and upper oesophagus and acts as a one way valve, allowing passage of pulmonary air from the trachea into the oesophagus and preventing aspiration of food and fluid from the oesophagus into the trachea. Persistent leakage through or around these prostheses is a recognized complication, the aetiology of which can vary widely, from mechanical issues with the prostheses themselves to anatomical and physiological issues associated with the reconstructed pharynx. We report a new technique of using Dysport in the management of intractable central leakage due to premature and forceful closure of the upper oesophageal sphincter during swallowing. This resulted in the pooling of fluids around the posterior flange of the prosthesis. This, along with the increased pressure from the muscle contraction, led to central leakage, as identified on videofluoroscopy. An injection of Dysport paralysed the upper oesophageal sphincter, preventing pooling of fluids around the prosthesis and the forcing open of the valve. The effect was to eliminate the leakage, and the patient did not require further injections over the following 22 months.

The multiple social and performance demands placed on college/university singers could put their still developing voices at risk. Previous ambulatory monitoring studies have analyzed the duration, intensity, and frequency (in Hz) of voice use among such students. Nevertheless, no studies to date have incorporated the simultaneous acoustic voice quality measures into the acquisition of these measures to allow for direct comparison during the same voicing period. Such data could provide greater insight into how young singers use their voices, as well as identify potential correlations between vocal dose and acoustic changes in voice quality. The purpose of this study was to assess the voice use and estimated voice quality of college/university singing students (18–24 y/o, N = 19). Ambulatory monitoring was conducted over three full, consecutive weekdays measuring voice from an unprocessed accelerometer signal measured at the neck. From this signal were analyzed traditional vocal dose metrics such as phonation percentage, dose time, cycle dose, and distance dose. Additional acoustic measures included perceived pitch, pitch strength, LTAS slope, alpha ratio, dB SPL 1–3 kHz, and harmonic-to-noise ratio. Major findings from more than 800 hours of recording indicated that among these students (a) higher vocal doses correlated significantly with greater voice intensity, more vocal clarity and less perturbation; and (b) there were significant differences in some acoustic voice quality metrics between non-singing, solo singing and choral singing.

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.

To provide a quantitative assessment of the occurrence of voice disorders among teachers and to identify associated work-related and individual factors in the teaching profession. A systematic review was conducted using three computerized databases on the occurrence of voice disorders among teachers and their associations with work-related and individual factors. Some of the keywords used were: "teacher", "voice disorder", "voice problem", and "dysphonia". Information regarding the occurrence of voice disorders and associations between work-related and individual factors and voice disorders were extracted from each paper. Occurrence and associations were expressed in prevalence and odds ratios, respectively. In total, 23 publications met the criteria for inclusion. All publications were cross-sectional studies. Prevalence estimates varied widely, reflecting disparity in definitions of "voice problem". Teachers had a significantly increased occurrence of voice disorders compared to other occupations. Several work-related and individual factors were consistently associated with voice disorders, most notably high levels of noise in classrooms, being a physical education instructor, and habitual use of a loud speaking voice. This review shows that teachers report voice disorders more often than non-teachers. Various work-related and individual factors are associated with reported voice disorders. Longitudinal studies are urgently required to get more insight into the development of voice disorders, their work-related determinants, and the consequences of these voice disorders for functioning and work performance among teachers. Describe the occurrence of voice disorders among teachers. Identify some work-related factors of voice disorders among teachers. Interpret the quality of the publications to describe or analyze the relationship between working conditions and voice disorders among teachers. Copyright © 2013 Elsevier Inc. All rights reserved.

Recognition of personally familiar voices benefits from the concurrent presentation of the corresponding speakers' faces. This effect of audiovisual integration is most pronounced for voices combined with dynamic articulating faces. However, it is unclear if learning unfamiliar voices also benefits from audiovisual face-voice integration or, alternatively, is hampered by attentional capture of faces, i.e., "face-overshadowing". In six study-test cycles we compared the recognition of newly-learned voices following unimodal voice learning vs. bimodal face-voice learning with either static (Exp. 1) or dynamic articulating faces (Exp. 2). Voice recognition accuracies significantly increased for bimodal learning across study-test cycles while remaining stable for unimodal learning, as reflected in numerical costs of bimodal relative to unimodal voice learning in the first two study-test cycles and benefits in the last two cycles. This was independent of whether faces were static images (Exp. 1) or dynamic videos (Exp. 2). In both experiments, slower reaction times to voices previously studied with faces compared to voices only may result from visual search for faces during memory retrieval. A general decrease of reaction times across study-test cycles suggests facilitated recognition with more speaker repetitions. Overall, our data suggest two simultaneous and opposing mechanisms during bimodal face-voice learning: while attentional capture of faces may initially impede voice learning, audiovisual integration may facilitate it thereafter.

Humans have a remarkable skill for voice-identity recognition: most of us can remember many voices that surround us as 'unique'. In this review, we explore the computational and neural mechanisms which may support our ability to represent and recognise a unique voice-identity. We examine the functional architecture of voice-sensitive regions in the superior temporal gyrus/sulcus, and bring together findings on how these regions may interact with each other, and additional face-sensitive regions, to support voice-identity processing. We also contrast findings from studies on neurotypicals and clinical populations which have examined the processing of familiar and unfamiliar voices. Taken together, the findings suggest that representations of familiar and unfamiliar voices might dissociate in the human brain. Such an observation does not fit well with current models for voice-identity processing, which by-and-large assume a common sequential analysis of the incoming voice signal, regardless of voice familiarity. We provide a revised audio-visual integrative model of voice-identity processing which brings together traditional and prototype models of identity processing. This revised model includes a mechanism of how voice-identity representations are established and provides a novel framework for understanding and examining the potential differences in familiar and unfamiliar voice processing in the human brain.

Academic voice is an oft-discussed, yet variably defined concept, and confusion exists over its meaning, evaluation, and interpretation. This paper will explore perspectives on academic voice and counterarguments to the positivist origins of objectivity in academic writing. While many epistemological and methodological perspectives exist, the feminist literature on voice is explored here as the contrary position. From the feminist perspective, voice is a socially constructed concept that cannot be separated from the experiences, emotions, and identity of the writer and, thus, constitutes a reflection of an author's way of knowing. A case study of how author presence can enhance meaning in text is included. Subjective experience is imperative to a practice involving human interaction. Nursing practice, our intimate involvement in patient's lives, and the nature of our research are not value free. A view is presented that a visible presence of an author in academic writing is relevant to the nursing discipline. The continued valuing of an objective, colorless academic voice has consequences for student writers and the faculty who teach them. Thus, a strategically used multivoiced writing style is warranted. © 2017 John Wiley & Sons Ltd.

Full Text Available The digital accessibility shows ways to information access in digital media that assist people with different types of disabilities to a better interaction with the computer independent of its limitations. Of these tools are composed by voice synthesizers, that supposedly simplifying their access to any recorded knowledge through digital technologies. However such tools have emerged originally in countries foreign language. Which brings us to the following research problem: the voice synthesizers are appropriate for reading digital books in the Portuguese language? The objective of this study was to analyze and classify different software tools voice synthesizers in combination with software digital book readers to support accessibility to e-books in Portuguese. Through literature review were identified applications software voice synthesizers, composing the sample analyzed in this work. We used a simplified version of the method of Multiple Criteria Decision Support - MMDA, to assess these. In the research 12 were considered readers of e-books and 11 software voice synthesizer, tested with six formats of e-books (E-pub, PDF, HTML, DOC, TXT, and Mobi. In accordance with the results, the software Virtual Vision achieved the highest score. Relative to formats, it was found that the PDF has measured a better score when summed the results of the three synthesizers. In the studied universe contacted that many synthesizers simply cannot be used because they did not support the Portuguese language.
Full Text Available Prosocial behavior is that which that encourages solidarity and harmony in interpersonal relationships, and produce personal or collective benefits. Although early research on job prosociality was focused on the study of conventional behaviors such as help, courtesy and sportsmanship, the identification and operationalization of new dimensions is rapidly expanding this nomological network. Such is the case of prosocial voice and prosocial silence, recently introduced in the scientific literature. The aim of this study is to explore possible relationships between employee’s voice and employee’s silence, and their personality structure; and examine the role of interpersonal justice perceptions on such relationships. We worked with a sample of 316 employees- aged 37 years and holding a 4.2-year signority working at public and private companies in southern and central Rosario (Argentina. The subjects completed Colquitt’ Justice Organizational Scale, Eysenck Personality Questionnaire, and Van Dyne’s Prosocial Voice and Prosocial Silence Scales. Extraversion and neuroticism emerged as the strongest predictors of prosocial voice and prosocial silence, respectively. Interpersonal justice perceptions emerged as moderators of the ‘natural’ tendency of extraverted workers to engage in prosocial voice, and emotionally controlled workers to engage in prosocial silence. Such findings would indicate that the promotion of high levels of interpersonal justice on job contexts could help workers to engage in more prosocial behavior with positive effects for the organization.

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.

Known influences of sex hormones on the voice would suggest pregnancy hormones could have an effect, yet studies using acoustic measures have not indicated changes. Additionally, no examination of the voice before the third trimester has been reported. Effect of pregnancy on the voice is relatively unexplored yet could be quite relevant to female speakers and singers. It is possible that spectral and aerodynamic measures would be more sensitive to tissue-level changes caused by pregnancy hormones. In this first longitudinal study of a 32-year-old woman's pregnancy, weekly voice samples were analyzed for acoustic (fundamental frequency, perturbation ratios of shimmer and jitter, Harmonic-to-Noise Ratio, spectral measures, and maximum phonation time) and aerodynamic (average airflow, peak flow, AC/DC ratio, open quotient, and speed quotient) parameters. All measures appeared generally stable during weeks 11-39 of pregnancy compared with 21 weeks postpartum. Slight decrease in minimum airflow and open speed quotient may reflect suspected vocal fold tissue changes. It is recommended that future studies monitor and test correlations among hormone levels, visual analyses of vocal fold mucosa, aerodynamic function, and glottal efficiency.

Full Text Available Abstract These days automotive has turned into a stand out amongst the most well-known modes of transportation on the grounds that a large number of Malaysians could bear to have an auto. There are numerous decisions of innovations in auto that have in the market. One of the engineering is voice controlled framework. Voice Recognition is the procedure of consequently perceiving a certain statement talked by a specific speaker focused around individual data included in discourse waves. This paper is to make an car controlled by voice of human. An essential pre-processing venture in Voice Recognition systems is to recognize the vicinity of noise. Sensitivity to speech variability lacking recognition precision and helplessness to mimic are among the principle specialized obstacles that keep the far reaching selection of speech-based recognition systems. Voice recognition systems work sensibly well with a quiet conditions however inadequately under loud conditions or in twisted channels. The key focus of the project is to control an electric car starter system.

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.

Although the hearing voices movement (HVM) has yet to take root in the US to the extent it has in the UK (and parts of Australia and Europe), recent publications and events, including a keynote presentation by UK hearing voices trainer Ron Coleman at the 2012 Annual NAMI convention and a TED 2013 talk in Los Angeles by British voice hearer and psychologist Eleanor Longden, suggest that the tide is starting to turn (Arenella, 2012; Grantham, 2012; Thomas, 2012). At its core, the HVM emphasizes a few basic, but important, points: that antipsychotic pharmacotherapy and various forms of psychotherapy that aim to suppress psychotic experiences are often--for too many people--ineffective or insufficient; that voices and other extreme experiences and beliefs carry important messages that need to be explored rather than silenced, and that voices themselves are often less of the problem than the difficulties individuals have in coping and negotiating with them (Corstens, Escher, & Romme, 2008; Longden, Corstens, Escher, & Romme, 2012; Place, Foxcroft, & Shaw, 2011).

American Indian adolescent pregnancy rates are high, yet little is known about how Native youth view primary pregnancy prevention. The aim was to identify pregnancy prevention strategies from the perspectives of both male and female urban Native youth to inform program development. Native Teen Voices (NTV) was a community-based participatory action research study in Minneapolis and St. Paul, Minnesota. Twenty focus groups were held with 148 Native youth who had never been involved in a pregnancy. Groups were stratified by age (13-15 and 16-18 years) and sex. Participants were asked what they would do to prevent adolescent pregnancy if they were in charge of programs for Native youth. Content analyses were used to identify and categorize the range and types of participants' recommendations within and across the age and sex cohorts. Participants in all cohorts emphasized the following themes: show the consequences of adolescent pregnancy; enhance and develop more pregnancy prevention programs for Native youth in schools and community-based organizations; improve access to contraceptives; discuss teen pregnancy with Native youth; and use key messages and media to reach Native youth. Native youth perceived limited access to comprehensive pregnancy prevention education, community-based programs and contraceptives. They suggested a variety of venues and mechanisms to address gaps in sexual health services and emphasized enhancing school-based resources and involving knowledgeable Native peers and elders in school and community-based adolescent pregnancy prevention initiatives. A few recommendations varied by age and sex, consistent with differences in cognitive and emotional development.

Given the unique nature of programs in professional veterinary medicine (PVM), the increasing numbers of students requesting accommodations for emotional support animals (ESAs) in higher education settings is of growing interest to student affairs and administrative staff in PVM settings. Since the legislation pertaining to this type of support animal differs from the laws governing disability service animals, colleges and universities now need to develop new policies and guidelines. Representatives from a sample of 28 PVM programs completed a survey about the prevalence of student requests for ESAs and service animals. PVM associate deans for academic affairs also reported their perceptions of this issue and the challenges these requests might pose within veterinary teaching laboratories and patient treatment areas. Responses indicated that approximately one third of PVM programs have received requests for ESAs (32.1%) in the last 2 years, 17.9% have had requests for psychiatric service animals, and 17.9% for other types of service animals. Despite this, most associate deans reported not having or not being aware of university or college policies pertaining to these issues. Most associate deans are interested in learning more about this topic. This paper provides general recommendations for establishing university or PVM program policies.

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face-voice pairs in which the face and voice were co-presented and were either "matched" (same person), "related" (two highly associated people), or "mismatched" (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.

A hammer drill design of a voice coil linear actuator, spring, linear bearings, and a hammer head was proposed. The voice coil actuator moves the hammer head to produce impact to the end of the drill bit. The spring is used to store energy on the retraction and to capture the rebound energy after each impact for use in the next impact. The maximum actuator stroke is 20 mm with the hammer mass being 200 grams. This unit can create impact energy of 0.4 J with 0.8 J being the maximum. This mechanism is less complex than previous devices meant for the same task, so it has less mass and less volume. Its impact rate and energy are easily tunable without changing major hardware components. The drill can be driven by two half-bridges. Heat is removed from the voice coil via CO2 conduction.

To describe the acoustic characteristics of voice in individuals with motor speech disorders after traumatic brain injury (TBI). Prospective study of 100 individuals with TBI based on consecutive referrals for motor speech evaluations. Subjects were audio tape-recorded while producing sustained vowels and single word and sentence intelligibility tests. Laryngeal airway resistance was estimated, and voice quality was rated perceptually. None of the subjects evidenced vocal parameters within normal limits. The most frequently occurring abnormal parameter across subjects was amplitude perturbation, followed by voice turbulence index. Twenty-three percent of subjects evidenced deviation in all five parameters measured. The perceptual ratings of breathiness were significantly correlated with both the amplitude perturbation quotient and the noise-to-harmonics ratio. Vocal quality deviation is common in motor speech disorders after TBI and may impact intelligibility.

How is "participation" ascribed meaning and practised in science and environment communication? And how are citizen voices articulated, invoked, heard, marginalised or silenced in those processes? Citizen Voices takes its starting point in the so-called dialogic or participatory turn in scientific and environmental governance in which practices claiming to be based on principles of participation, dialogue and citizen involvement have proliferated. The book goes beyond the buzzword of "participation" in order to give empirically rich, theoretically informed and critical accounts of how citizen participation is understood and enacted in mass mediation and public engagement practices. A diverse series of studies across Europe and the US are presented, providing readers with empirical insights into the articulation of citizen voices in different national, cultural and institutional contexts. Building bridges across media and communication studies, science and technology studies, environmental studies and urban pl...

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.

This paper reports that transmitting digital voice via packetized mobile communications systems that employ relatively short packet lengths and narrow bandwidths often necessitates very low bit rate coding of the voice data. Sandia National Laboratories is currently developing an efficient voice coding system operating at 800 bits per second (bps). The coding scheme is a modified version of the 2400 bps NSA LPC-10e standard. The most significant modification to the LPC-10e scheme is the vector quantization of the line spectrum frequencies associated with the synthesis filters. An outline of a hardware implementation for the 800 bps coder is presented. The speech quality of the coder is generally good, although speaker recognition is not possible. Further research is being conducted to reduce the memory requirements and complexity of the vector quantizer, and to increase the quality of the reconstructed speech. This work may be of use dealing with nuclear materials

We propose a novel analysis alternative, based on two Fourier Transforms for emotion recognition from speech. Fourier analysis allows for display and synthesizes different signals, in terms of power spectral density distributions. A spectrogram of the voice signal is obtained performing a short time Fourier Transform with Gaussian windows, this spectrogram portraits frequency related features, such as vocal tract resonances and quasi-periodic excitations during voiced sounds. Emotions induce such characteristics in speech, which become apparent in spectrogram time-frequency distributions. Later, the signal time-frequency representation from spectrogram is considered an image, and processed through a 2-dimensional Fourier Transform in order to perform the spatial Fourier analysis from it. Finally features related with emotions in voiced speech are extracted and presented. (paper)

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.

Whispered vowels, produced with no vocal fold vibration, lack the periodic temporal fine structure which in voiced vowels underlies the perceptual attribute of pitch (a salient auditory cue to speaker sex). Voiced vowels possess no temporal fine structure at very short durations (below two glottal cycles). The prediction was that speaker-sex discrimination performance for whispered and voiced vowels would be similar for very short durations but, as stimulus duration increases, voiced vowel pe...
Full Text Available Although eye movements during reading are modulated by cognitive processing demands, they also reflect visual sampling of the input, and possibly preparation of output for speech or the inner voice. By simultaneously recording eye movements and the voice during reading aloud, we obtained an output measure that constrains the length of time spent on cognitive processing. Here we investigate the dynamics of the eye-voice span (EVS, the distance between eye and voice. We show that the EVS is regulated immediately during fixation of a word by either increasing fixation duration or programming a regressive eye movement against the reading direction. EVS size at the beginning of a fixation was positively correlated with the likelihood of regressions and refixations. Regression probability was further increased if the EVS was still large at the end of a fixation: if adjustment of fixation duration did not sufficiently reduce the EVS during a fixation, then a regression rather than a refixation followed with high probability. We further show that the EVS can help understand cognitive influences on fixation duration during reading: in mixed model analyses, the EVS was a stronger predictor of fixation durations than either word frequency or word length. The EVS modulated the influence of several other predictors on single fixation durations. For example, word-N frequency effects were larger with a large EVS, especially when word N-1 frequency was low. Finally, a comparison of single fixation durations during oral and silent reading showed that reading is governed by similar principles in both reading modes, although EVS maintenance and articulatory processing also cause some differences. In summary, the eye-voice span is regulated by adjusting fixation duration and/or by programming a regressive eye movement when the eye-voice span gets too large. Overall, the EVS appears to be directly related to updating of the working memory buffer during reading.
Full Text Available [b]introduction[/b]. In a group of persons using the voice occupationally, the frequent symptoms are hoarseness, voice fatigability and aphonia. Pathological changes in the larynx may have organic or functional character which require different methods of treatment and rehabilitation. Visualization of vibrations of the vocal folds is an essential condition for an appropriate assessment of the causes of dysphonia. [b]objective[/b]. The purpose of the study is assessment of the usefulness of a high-speed imaging (HSI system in the diagnosis of functional and organic dysphonia of occupational character, compared with digital kymography (DKG and digital stroboscopy (DS with a high resolution module. [b]material and methods[/b]. The study group consisted of 64 patients with voice quality disorders with features of occupational dysphonia. The control group consisted of 15 patients with euphonic voice. Analysis of the voice quality parameters during phonation of the ‘e’ vowel was performed using HSI, DKG and stroboscopy of high resolution, by means of a digital HS camera (HRES Endocam, Richard Wolf GmbH, Knittlingen, Germany. Vocal folds vibrations were registered at the rate of 4,000 frames per second. [b]results[/b]. HSI is the most reliable diagnostic tool giving the possibility of an analysis of the true vibrations of the vocal folds. It also enables an observation of the aperiodicity of vibrations of the vocal folds, while DS with high resolution allows diagnosis of the periodicity of the vibrations. [b]conclusions[/b]. HSI is particularly useful in the diagnosis of neurologically-based pathology of the voice (paralytic dysphonia and organic dysphonia. The quickest method of diagnosing the phonatory paresis of the glottis is DKG. The advantage of both HSI and DKG is the non-invasiveness of examinations; however, their limitations are time-consuming and the high cost of equipment.

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.

Full Text Available According to my claim that voice as a phenomenon cannot be materialised or located, neither in the (voice organ of the self nor in the (ear of the other, I coined the term [au]/[o]-tophonography for my examination of the possibilities of performing subjectivity in writing and in sound productions. Drawing on the theory of performativity in its deconstructive senses (see BUTLER, 1993, 1997, 1999/1990; DERRIDA, 1988/1972, 1997/1967, 2002/1981; SMITH, 1995 my performative epistemology reaches beyond the theoretical, including the practical and the aesthetical, aiming at questioning notions of "self", "audience", "voice", "writing" and "communication". "The show with the voice" (http://www.qualitative-research.net/fqs-texte/2-08/08-2-27_audio.mp3 is an example of this practice. It parodies the medico-scientific approach to the human voice by presenting some of its possible appearances (the "normal", the "disordered", the "homosexual" and the "transsexual" voice in an audio collage that takes the shape of a mock tutorial. Through re-contextualising and re-compiling voice samples from different sources that are usually kept apart (e.g. the lecturer's voice, the researcher's voice, the artist's voice, the autobiographer's voice I open a space for a multidisciplinary and creative perspective to the examination of voice.

Despite anecdotal reports of voice impairment in quadriplegia, the exact nature of these impairments is not well described in the literature. This article details objective and subjective voice assessments for people with quadriplegia at baseline and after a respiratory-targeted singing intervention. Randomized controlled trial. Twenty-four participants with quadriplegia were randomly assigned to a 12-week program of either a singing intervention or active music therapy control. Recordings of singing and speech were made at baseline, 6 weeks, 12 weeks, and 6 months postintervention. These deidentified recordings were used to measure sound pressure levels and assess voice quality using the Multidimensional Voice Profile and the Perceptual Voice Profile. Baseline voice quality data indicated deviation from normality in the areas of breathiness, strain, and roughness. A greater percentage of intervention participants moved toward more normal voice quality in terms of jitter, shimmer, and noise-to-harmonic ratio; however, the improvements failed to achieve statistical significance. Subjective and objective assessments of voice quality indicate that quadriplegia may have a detrimental effect on voice quality; in particular, causing a perception of roughness and breathiness in the voice. The results of this study suggest that singing training may have a role in ameliorating these voice impairments. Copyright © 2014 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

Demographic data, subjective und objective voice analysis as well as self-assessment of voice quality from applicants for a school of speech therapists were investigated. Demographic data from 116 applicants were collected and their voice quality assessed by three independent judges. An objective evaluation was done by maximum phonation time, average fundamental frequency, dynamic range and percent of jitter and shimmer by means of Goettinger Hoarseness diagram. Self-assessment of voice quality was done by "voice handicap index questionnaire". The twenty successful applicants had a physiological voice in 95 %, they were all musical and had university entrance qualifications. Subjective voice assessment showed in 16 % of the applicants a hoarse voice. In this subgroup an unphysiological vocal use was observed in 72 % and a reduced articulation in 45 %. The objective voice parameters did not show a significant difference between the 3 groups. Self-assessment of the voice was inconspicuous in all applicants. Applicants with general qualification for university entrance, musicality and a physiological voice were more likely to be successful. There were main differences between self assessment of voice and quantitative analysis or subjective assessment by three independent judges.

Aims: To prospectively analyze the objective voice quality before and after radiotherapy (RT) for early glottic cancer and to evaluate the role of different factors that may affect it. Methods: Patients with T1-T2N0M0 glottic cancer underwent voice quality assessment before treatment and after radical RT. Post-RT voice quality was compared to the voice at diagnosis and the voice of healthy individuals used as controls. A comprehensive set of voice parameters were measured. The effects of age, smoking history, T stage, anterior commissure (AC) involvement, radiation dose, fractionation and volumes on pre-treatment and post-treatment voice quality were analyzed. Results: The voice quality data of 50 patients were analyzed. Following treatment, there was a significant improvement in the majority of measured parameters. However, perturbation and HNR remained inferior compared to controls. A history of smoking, AC involvement and larger RT volumes resulted in poorer voice parameters following RT. There was no significant impact of age alone. T2 tumors had an inferior voice quality before treatment, but did not remain inferior following RT. Hypofractionated RT did not show any negative impact. Conclusions: There is a considerable improvement of voice quality following RT. Several factors may have specific effects on pre-treatment and post-treatment voice

Despite an increasing volume of cross-sectional work on auditory verbal hallucinations (hearing voices), there remains a paucity of work on how the experience may change over time. The first aim of this study was to attempt replication of a previous finding that beliefs about voices are enduring and stable, irrespective of changes in the severity of voices, and do not change without a specific intervention. The second aim was to examine whether voice-hearers' interrelations with their voices change over time, without a specific intervention. A 12-month longitudinal examination of these aspects of voices was undertaken with hearers in routine clinical treatment (N = 18). We found beliefs about voices' omnipotence and malevolence were stable over a 12-month period, as were styles of interrelating between voice and hearer, despite trends towards reductions in voice-related distress and disruption. However, there was a trend for beliefs about the benevolence of voices to decrease over time. Styles of interrelating between voice and hearer appear relatively stable and enduring, as are beliefs about the voices' malevolent intent and power. Although there was some evidence that beliefs about benevolence may reduce over time, the reasons for this were not clear. Our exploratory study was limited by only being powered to detect large effect sizes. Implications for clinical practice and future research are discussed.

Full Text Available Background and Aim: Reflux laryngitis is extremely common among patients with voice disorder. Medical therapy approaches are not efficient enough. The main goal of this study is to assess the acoustic and laryngeal characteristics of patients with dysphonia before and after medical or voice therapy, and to evaluate the effectiveness of each.Methods: In this retrospective study, 16 reflux laryngitis patients were assessed. Five received complete voice therapy, tow ceased voice therapy and nine received medication. Perceptual voice evaluation was performed by a speech-language pathologist, the severity of voice problem was calculated, based on the affected acoustic and laryngeal characteristics pre- and post-treatment.Results: Post-treatment evaluation in patients who received complete voice therapy indicates 80 percent improvement in the severity of disorder and 100 percent improvement in the perceptual voice evaluation. After medical therapy, we observed that voice disorder and perceptual voice evaluation are improved 44 and 66 percent respectively. The improvement was statistically significant in both treatment approaches: complete voice therapy (P=0.039 and medical therapy (p=0.017.Conclusion: In patients with reflux laryngitis, most acoustic and laryngeal characteristics were normal and satisfying after the treatment. It can be concluded that the proficiency of voice therapy in improving the acoustic and laryngeal characteristics is comparable to medical therapy
