The voice is a basic tool in human communication and an important factor in a positive self-understanding and identity, both for the teacher's sense of profession and for the pupils' ability to express themselves orally; two perspectives of great importance in the Norwegian National Curriculum. Voice disorders are common among teachers world-wide…

Voice - How humans communicate?

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

The quadratic-form identity for constructing the Hamiltonian structure of integrable systems

International Nuclear Information System (INIS)

2005-01-01

A usual loop algebra, not necessarily the matrix form of the loop algebra A-tilde n-1 , is also made use of for constructing linear isospectral problems, whose compatibility conditions exhibit a zero-curvature equation from which integrable systems are derived. In order to look for the Hamiltonian structure of such integrable systems, a quadratic-form identity is created in the present paper whose special case is just the trace identity; that is, when taking the loop algebra A-tilde 1 , the quadratic-form identity presented in this paper is completely consistent with the trace identity

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

Science.gov (United States)

Hughes, Susan M; Harrison, Marissa A

2013-01-01

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

Voicing the Technological Body. Some Musicological Reflections on Combinations of Voice and Technology in Popular Music

Directory of Open Access Journals (Sweden)

Florian Heesch

2016-05-01

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.

Masculine Voices Predict Well-Being in Female-to-Male Transgender Individuals.

Watt, Seth O; Tskhay, Konstantin O; Rule, Nicholas O

Voices convey important social information about an individual's identity, including gender. This is especially relevant to transgender individuals, who cite voice alteration as a primary goal of the gender alignment process. Although the voice is a primary target of testosterone therapy among female-to-male (FTM) trans people, little research has explored the effects of such changes on their psychological well-being. Here, we investigated how FTMs' vocal gender related to their well-being. A total of 77 FTMs (M age  = 25.45 years, SD = 6.77) provided voice samples and completed measures of their well-being and psychological health. An independent group of 32 naïve raters (M age  = 22.16 years, SD = 8.21) subsequently rated the voice samples for masculinity. We found that FTMs whose voices sounded more congruent with their experienced gender (i.e., sounded more masculine) reported greater well-being (better life satisfaction, quality of life, and self-esteem; lower levels of anxiety and depression) than FTMs with less gender congruent (i.e., more feminine) voices (β = .48). The convergence between outwardly perceived vocal gender and gender identity brought about through hormone replacement therapy may therefore support greater well-being for FTMs.

Integrating cues of social interest and voice pitch in men's preferences for women's voices.

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

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

Directory of Open Access Journals (Sweden)

Simone Sulpizio

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

Robust matching for voice recognition

Higgins, Alan; Bahler, L.; Porter, J.; Blais, P.

1994-10-01

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

The political gesture of intimacy: voice, experience and media in Generation Y, by Yoani Sánchez

Directory of Open Access Journals (Sweden)

Márcio Serelle

2012-07-01

Full Text Available This article aims at discussing, mainly through the analysis of the blog Generation Y, how the exposing and sharing on the internet of Yoani Sánchez´s intimacy generate narratives of counter-power, in which the claim by the uniqueness of the voice becomes, in the cyberactivism act, gesture of a whole generation. Moving in the blogosphere,an identity based, in principle, on the ordinariness of the self turns into a strong collective identity. This evasion of privacy, understood as a form of resistance and protection, denounces the precariousness of modern distinctions between the spheres of private and public as a theoretical approach to these reports on digital social networks. From the studies about the biographical space nowadays, provided by authors such as Arfuch (2010 and Sarlo (2007, this work seeks to understand both the effect of transparency and truth of this speech in first person, and the process of construction of the self, through the recollection of diverse voices in the constitution of an apparatus similar to the logos bioethikos defined by Foucault (2009, linking voice, discourse equipment and media.

[Voice and vibration sensations in the speech forming organs: clinical and theoretical aspects of rare symptoms specific for schizophrenia].

Science.gov (United States)

Vilela, W; Lolas, F; Wolpert, E

1978-01-01

When studying 750 psychiatric in-patients with psychoses of various diagnostic groups, the symptoms of voice sensations and vibration feelings could only be found among patients with paranoid schizophrenia. In addition, these symptoms were located exclusively in body areas that are involved in the peripheral motor production of voice and speech (areas of head, throat, thorax). In 11 of 15 such cases that could be identified, the sensations of voices and vibrations occurred simultaneously and in identical body parts; in the remaining 4 cases only voices without vibration sensations were reported. Therefore these symptoms can be considered as highly specific for schizophrenia. According to the terminology of Bleuler these two symptoms are because of their rareness to be taken as accessoric symptoms; according to the terminology of Kurt Schneider they have the value of first rank symptoms because of their highly diagnostic specifity for schizophrenia. The pathogenesis of these symptoms is on the one hand discussed under the perspective of language development and the changing function of language for behaviour control; on the other hand, the pathogenesis of these symptoms is discussed from the viewpoint of cybernetic, or neurophysiological-neuroanatomical foundation of speech production and speech control. Both models of explanation have in common that the ideational component of speech is noticed as acustic halluzinations and the motor proprioceptive part of speech is noticed as sensation of vibrations, both in a typically schiphrenic manner, i.e. dissociated and ego-alienated.

Auditory and Visual Modulation of Temporal Lobe Neurons in Voice-Sensitive and Association Cortices

Perrodin, Catherine; Kayser, Christoph; Logothetis, Nikos K.

2014-01-01

Effective interactions between conspecific individuals can depend upon the receiver forming a coherent multisensory representation of communication signals, such as merging voice and face content. Neuroimaging studies have identified face- or voice-sensitive areas (Belin et al., 2000; Petkov et al., 2008; Tsao et al., 2008), some of which have been proposed as candidate regions for face and voice integration (von Kriegstein et al., 2005). However, it was unclear how multisensory influences occur at the neuronal level within voice- or face-sensitive regions, especially compared with classically defined multisensory regions in temporal association cortex (Stein and Stanford, 2008). Here, we characterize auditory (voice) and visual (face) influences on neuronal responses in a right-hemisphere voice-sensitive region in the anterior supratemporal plane (STP) of Rhesus macaques. These results were compared with those in the neighboring superior temporal sulcus (STS). Within the STP, our results show auditory sensitivity to several vocal features, which was not evident in STS units. We also newly identify a functionally distinct neuronal subpopulation in the STP that appears to carry the area's sensitivity to voice identity related features. Audiovisual interactions were prominent in both the STP and STS. However, visual influences modulated the responses of STS neurons with greater specificity and were more often associated with congruent voice-face stimulus pairings than STP neurons. Together, the results reveal the neuronal processes subserving voice-sensitive fMRI activity patterns in primates, generate hypotheses for testing in the visual modality, and clarify the position of voice-sensitive areas within the unisensory and multisensory processing hierarchies.

Self-Voice, but Not Self-Face, Reduces the McGurk Effect

Directory of Open Access Journals (Sweden)

Christopher Aruffo

2011-10-01

Full Text Available The McGurk effect represents a perceptual illusion resulting from the integration of an auditory syllable dubbed onto an incongruous visual syllable. The involuntary and impenetrable nature of the illusion is frequently used to support the multisensory nature of audiovisual speech perception. Here we show that both self-speech and familiarized speech reduce the effect. When self-speech was separated into self-voice and self-face mismatched with different faces and voices, only self-voice weakened the illusion. Thus, a familiar vocal identity automatically confers a processing advantage to multisensory speech, while a familiar facial identity does not. When another group of participants were familiarized with the speakers, participants' ability to take advantage of that familiarization was inversely correlated with their overall susceptibility to the McGurk illusion.

Speaking in Character: Voice Communication in Virtual Worlds

Science.gov (United States)

Wadley, Greg; Gibbs, Martin R.

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

Voice and silence in organizations

Voice and silence are interrelated and intertwined strategic forms ofcommunication which presuppose each other in such a way that the absence of one would minimize completely the other’s presence. Social actors are not voice, or silence. Social actors can have voice or silence, they can do both because they operate at multiple levels and deal with multiple issues at different moments in time.

Voice is an important gender marker in the transition process as a transgender individual accepts a new gender identity. The objectives of this study were to describe and relate aspects of a perceptual-auditory analysis and the fundamental frequency (F0) of male-to-female (MtF) transsexual individuals. A case-control study was carried out with individuals aged 19-52 years who attended the Gender Identity Program of the Hospital de Clínicas of Porto Alegre. Vocal recordings from the MtF transgender and cisgender individuals (vowel /a:/ and six phrases of Consensus Auditory Perceptual Evaluation Voice [CAPE-V]) were edited and randomly coded before storage in a Dropbox folder. The voices (vowel /a:/) were analyzed by consensus on the same day by two judge speech therapists who had more than 10 years of experience in the voice area using the GRBASI perceptual-auditory vocal evaluation scale. Acoustic analysis of the voices was performed using the advanced Multi-Dimensional Voice Program software. The resonance focus and the degrees of masculinity and femininity for each voice recording were determined by listening to the CAPE-V phrases, for the same judges. There were significant differences between the groups regarding a greater frequency of subjects with F0 between 80 and 150 Hz (P = 0.003), and a greater frequency of hypernasal resonant focus (P < 0.001) in the MtF cases and greater frequency of subjects with absence of roughness (P = 0.031) in the control group. The MtF group of individuals showed altered vertical resonant focus, more masculine voices, and lower fundamental frequencies. The control group showed a significant absence of roughness.

Numerous behavioral studies have found a modulation effect of phonological experience on voice discrimination. However, the neural substrates underpinning this phenomenon are poorly understood. Here we manipulated language familiarity to test the hypothesis that phonological experience affects voice discrimination via mediating the engagement of multiple perceptual and cognitive resources. The results showed that during voice discrimination, the activation of several prefrontal regions was modulated by language familiarity. More importantly, the same effect was observed concerning the functional connectivity from the fronto-parietal network to the voice-identity network (VIN), and from the default mode network to the VIN. Our findings indicate that phonological experience could bias the recruitment of cognitive control and information retrieval/comparison processes during voice discrimination. Therefore, the study unravels the neural substrates subserving the modulation effect of phonological experience on voice discrimination, and provides new insights into studying voice discrimination from the perspective of network interactions.

VOICES-POSITIONS IN DISCOURSES: HOW IS IDENTITY POSSIBLE?

Directory of Open Access Journals (Sweden)

T. V. Podolska

2017-06-01

Full Text Available The article is devoted to the question of identity of a modern man which constantly emerges as a powerful wave and is brought up to date with new force. Thus, continuing scientific research on identity and individual identity are being held, but from a different point of view, i.e. by using modernized methodology. The purpose of the research is to substantiate scientific approaches, epistemological coordinate changes, and critical trends in the issue of identity that would allow solving the problems of nature of a modern person being. In this respect the narrative approach is considered to be up-to-date. Methodology. Interdisciplinary research perspective allowed using a comprehensive methodology where, complementing each other, there are phenomenological, cultural, anthropological, hermeneutic, systematic, historical and genetic methods and method historical-philosophical and socio-cultural comparative studies. Originality. Personal being occurs in time, and it’s the narrative method, the main feature of which is its temporality and extension, that can involve all of us to self-understanding on the basis of certain turning points in our history. The compliance with relevant ethical standards in dealing with other people, and requirements of certain supra-individual structures properly correlates with our least resistant inner world view and outlook. As the narrative identity exists in the subjective sense of time, experience and understanding of the events of life, thus, despite the ontogenetic secondary of the personal identity with respect to the social one, the domination of the former one is more probable. Conclusions. The adoption of such an understanding of identity by everyone signifies a high degree of responsibility for self-constructing, which implicitly assumes not just to say “I”, but first of all to define your being as a certain social debt: to another person, to society, its history and everyday life through which we get a

Rothenberg, Martin; Schutte, Harm K

2016-11-01

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

Representation of National Identity in Malaysian State Mosque Built Form as a Socio- cultural Product

Directory of Open Access Journals (Sweden)

Alice Sabrina Ismail

2018-01-01

Full Text Available The formation of national identity is the essence for a multi-racial country like Malaysia because it can strengthen national solidarity, create a common aspiration, and sustain the continuity of a historical heritage with multiple ethnicity and background. Nevertheless, the characteristics of this national identity is still not fully dealt with from an architectural aspect. Hence, the purpose of this paper is to critically examine the problem of national architectural identity in Malaysia. This is vital to uncover the resulting design principles with national architectural identity characteristics by referencing to three typologies of local state mosque as case study. The finding outlines that there are six architectural principles that influence the formation of national identity. These are the understanding of built form detail elements, materials usage, local style composition and expression, application of organic theory, designing a regionalistic articulation of space and form as well as an understanding of democratic values form to reflect the characteristics of national identity. These established referential guideline design on national identity is of benefit for future designers, builders, developer and related authority to produce built form that symbolizes nation political values as well as responsive to the existing social culture context.

Shielding voices: The modulation of binding processes between voice features and response features by task representations.

Bogon, Johanna; Eisenbarth, Hedwig; Landgraf, Steffen; Dreisbach, Gesine

2017-09-01

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.

METHODS FOR QUALITY ENHANCEMENT OF USER VOICE SIGNAL IN VOICE AUTHENTICATION SYSTEMS

Directory of Open Access Journals (Sweden)

O. N. Faizulaieva

2014-03-01

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.

2014-06-01

In noisy, multipeople talking environments such as a cocktail party, listeners can use various perceptual and/or cognitive cues to improve recognition of target speech against masking, particularly informational masking. Previous studies have shown that temporally prepresented voice cues (voice primes) improve recognition of target speech against speech masking but not noise masking. This study investigated whether static face image primes that have become target-voice associated (i.e., facial images linked through associative learning with voices reciting the target speech) can be used by listeners to unmask speech. The results showed that in 32 normal-hearing younger adults, temporally prepresenting a voice-priming sentence with the same voice reciting the target sentence significantly improved the recognition of target speech that was masked by irrelevant two-talker speech. When a person's face photograph image became associated with the voice reciting the target speech by learning, temporally prepresenting the target-voice-associated face image significantly improved recognition of target speech against speech masking, particularly for the last two keywords in the target sentence. Moreover, speech-recognition performance under the voice-priming condition was significantly correlated to that under the face-priming condition. The results suggest that learned facial information on talker identity plays an important role in identifying the target-talker's voice and facilitating selective attention to the target-speech stream against the masking-speech stream. © 2014 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Raising voices: How sixth graders construct authority and knowledge in argumentative essays

Science.gov (United States)

Monahan, Mary Elizabeth

This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice

Harsh voice quality and its association with blackness in popular American media.

Moisik, Scott Reid

Performers use various laryngeal settings to create voices for characters and personas they portray. Although some research demonstrates the sociophonetic associations of laryngeal voice quality, few studies have documented or examined the role of harsh voice quality, particularly with vibration of the epilaryngeal structures (growling). This article qualitatively examines phonetic properties of vocal performances in a corpus of popular American media and evaluates the association of voice qualities in these performances with representations of social identity and stereotype. In several cases, contrasting laryngeal states create sociophonetic contrast, and harsh voice quality is paired with the portrayal of racial stereotypes of black people. These cases indicate exaggerated emotional states and are associated with yelling/shouting modes of expression. Overall, however, the functioning of harsh voice quality as it occurs in the data is broader and may involve aggressive posturing, comedic inversion of aggressiveness, vocal pathology, and vocal homage. © 2013 S.

Rantala, Leena M; Hakala, Suvi J; Holmqvist, Sofia; Sala, Eeva

2012-11-01

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

Academic voice: On feminism, presence, and objectivity in writing.

Science.gov (United States)

Mitchell, Kim M

2017-10-01

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.

Understanding the 'Anorexic Voice' in Anorexia Nervosa.

Pugh, Matthew; Waller, Glenn

2017-05-01

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

Mawson, Amy; Berry, Katherine; Murray, Craig; Hayward, Mark

2011-09-01

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.

Voice Quality and Gender Stereotypes: A Study of Lebanese Women With Reinke's Edema.

2016-12-01

Women with Reinke's edema (RW) report being mistaken for men during telephone conversations. For this reason, their masculine-sounding voices are interesting for the study of gender stereotypes. The study's objective is to verify their complaint and to understand the cues used in gender identification. Using a self-evaluation study, we verified RW's perception of their own voices. We compared the acoustic parameters of vowels produced by 10 RW to those produced by 10 men and 10 women with healthy voices (hereafter referred to as NW) in Lebanese Arabic. We conducted a perception study for the evaluation of RW, healthy men's, and NW voices by naïve listeners. RW self-evaluated their voices as masculine and their gender identities as feminine. The acoustic parameters that distinguish RW from NW voices concern fundamental frequency, spectral slope, harmonicity of the voicing signal, and complexity of the spectral envelope. Naïve listeners very often rate RW as surely masculine. Listeners may rate RW's gender incorrectly. These incorrect gender ratings are correlated with acoustic measures of fundamental frequency and voice quality. Further investigations will reveal the contribution of each of these parameters to gender perception and guide the treatment plan of patients complaining of a gender ambiguous voice.

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.

Listening to their voices: Exploring mathematics-science identity development of African American males in an urban school community

Science.gov (United States)

Wilson, Kimi Leemar

National data continues to show an underrepresentation of African American males pursuing science, technology, engineering and mathematics (STEM) majors, careers and professions in the United States. Whites and Asian Americans are continuously positioned as the face of STEM education and participation. And while research has provided ways to support mathematics and science learning for African American males, there still remains a gap in understanding how their formed mathematics-science identities in K-12 public schooling influences STEM participation. The research undertaken in this study explores this gap, and uses an integrative identity framework to understand mathematics-science identity development which goes beyond personal identity, and explores the relational, collective and material components of identity. Specifically, this research seeks to answer the following research questions: What are the shared lived experiences that exist between a group of African American male students developing a mathematics-science identity, and how these shared lived experiences shape their mathematics-science identity development? Therefore, by analyzing African American males lived experiences employing an integrative identity framework fosters a greater understanding of how mathematics-science identity is formed in K-12 public schools, which impacts STEM education and participation. The high school aged youth featured in this study consist of four African American males, who live in a moderate size city in California. Data for this study consists of observations, phenomenological interviews, and policy document analysis that took place over six months. Data has been analyzed to describe and interpret the young men's mathematics and science experiences, as revealed in their K-12 public school education. This inquiry sought to make meaning of how African American males experience mathematics and science teaching and learning within K-12 public schooling and how these

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.

2017-04-01

Full Text Available The "Panama Papers" leakage implicated several African leaders in global corruption deals. It confirmed perceptions that these leaders care little for their people. African leaders who overstay term limits are the focus of Western democratic ire. Pro-democracy movements, the overthrow of regimes characterised as undemocratic gain unquestioned media coverage and praise. African leaders are summoned to the International Criminal Court in The Hague; their societies debate whether justice can be administered from outside. Increasingly, voices question African political and developmental processes. African Literature participates in struggles defining modern Africa’s search for identity and its own definition of leadership. It points to possibilities rooted in African Oral Tradition and in customs predating various colonial systems. Leadership forms that societies choose are closely linked to perceptions of identity. This paper examines the crisis of identity which has resulted in Africa’s crisis of leadership and looks at approaches taken by African writers and filmmakers: Malian filmmaker Cheik Oumar Sissoko’s film "La Genèse" (1999, South African writer Zakes Mda’s novels "Ways of Dying" (1995, "Heart of Redness" (2000.

Lady Catherine Cantor Cutiva

2015-09-01

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 analyses the poem “Vozes-Mulheres” (voices-women, by Conceição Evaristo. Black women who are part of the extended family of the poetic persona are represented by the voices presented in the poem. The aim of this paper is apply the theory of Third World Women brought forth by Gayatri Spivak and developed by scholars as Chandra Talpade Mohanty to the voices in the poem by discussing the voices of the Third World Women and the subaltern studies.  The investigation methodology is based in theoretical texts that discuss if the subaltern has a voice, and the attempt of agency developed by the voices in the poem, as studied by Spivak (1987, Mohanty (2003, Maggio (2007 and others. In the poem, one can observe the voice as a resistance mechanism by the poetic persona who struggles for a space in society. The payback happens via speech, and speech becomes the tool for the liberation of the black woman persona. The results of the analysis evidence that the identity of the black women voices is constructed from the moment that the present voice mixes up with the voices of the previous and the future generations, so those voices can be heard. By using her voice as a poor, black woman and intellectual, Evaristo focuses on her own condition and the possibilities of reconfiguring her role in society as a black woman.

Self-perception of voice has a significant psychosocial impact on transgender persons. Research about the evolution of self-perception of voice during cross-sex hormone therapy (CSHT) is lacking. The aim of this study was to examine if self-perception of voice changes during CSHT, and if a change of serum testosterone levels as a result of CSHT can predict a change of self-perception of voice. Prospective longitudinal study. The Transsexual Voice Questionnaire (TVQ), consisting of three factors-anxiety and avoidance (AA), gender identity (GI), and voice quality (VQ)-was used. Transgender persons completed the TVQ at baseline (80 trans men and 103 trans women), after 3 and 12 months of CSHT follow-up. Trans men: From 0 to 3 months, 0 to 12 months, and 3 to 2 months of CSHT, the AA and GI scores improved. From 0 to 3 months of CSHT, the increasing testosterone level was predictive for the improvements of AA and GI scores. Trans women: From 0 to 3 months, the GI score improved. From 0 to 12 months, the AA, GI, and VQ scores improved. Improvements of self-perception of voice could not be predicted by changing serum testosterone levels. During CSHT, self-perception of voice improves in both trans men and trans women. In trans men only, the improving self-perception of voice during the first 3 months can be attributed to the CSHT. For trans women, this study supports that testosterone has acted irreversibly virializing to the voice before CSHT, if they already went through male puberty. 4.

2013-09-01

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.

The middle-class nature of identity and its implications for education: a genealogical analysis and reevaluation of a culturally and historically bounded concept.

Science.gov (United States)

Matusov, Eugene; Smith, Mark Philip

2012-09-01

We consider identity as a historically emerging discourse that requires genealogical analysis - not to discover the roots of our identity but to commit [ourselves] to its dissipation (Foucault 1977, p. 162). We suggest analyzing identity through the history of socio-economic classes, their life struggles, ambitions, development, and reproduction. We see learning not as a project of transformation of identity, but rather as developing access to socially valuable practices and developing one's own voice within these practices (through addressing and responding to other voices). The access and voice projects free agents from unnecessary finalization and objectivization by oneself and others (Bakhtin 1999; Bakhtin 1990). In education, we should develop indigenous discourses of learning and develop a conceptual framework that makes analysis of diverse discourses possible. We argue that learning, as transformation of participation in a sociocultural practice to gain more access, is a better conceptual framework than learning as transformation of identity.

Voice amplification for primary school teachers with voice disorders: a randomized clinical trial.

Bovo, Roberto; Trevisi, Patrizia; Emanuelli, Enzo; Martini, Alessandro

2013-06-01

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

Full Text Available Often collective identities are classified depending on their contents and rarely depending on their forms. Differentiation between soft identity and hard identity is applied to diverse collective identities: religious, political, national, tribal ones, etc. This classification is made following the principal dimensions of collective identities: type of classification (univocal and exclusive or relative and contextual, the absence or presence of conflictsof loyalty, selective or totalitarian, objective or subjective conception, among others. The different characteristics analysed contribute to outlining an increasingly frequent type of identity: the authoritarian identity.

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.

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.

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.

Individual primates can be identified by the sound of their voice. Macaques have demonstrated an ability to discern conspecific identity from a harmonically structured 'coo' call. Voice recognition presumably requires the integrated perception of multiple acoustic features. However, it is unclear how this is achieved, given considerable variability across utterances. Specifically, the extent to which information about caller identity is distributed across multiple features remains elusive. We examined these issues by recording and analysing a large sample of calls from eight macaques. Single acoustic features, including fundamental frequency, duration and Weiner entropy, were informative but unreliable for the statistical classification of caller identity. A combination of multiple features, however, allowed for highly accurate caller identification. A regularized classifier that learned to identify callers from the modulation power spectrum of calls found that specific regions of spectral-temporal modulation were informative for caller identification. These ranges are related to acoustic features such as the call's fundamental frequency and FM sweep direction. We further found that the low-frequency spectrotemporal modulation component contained an indexical cue of the caller body size. Thus, cues for caller identity are distributed across identifiable spectrotemporal components corresponding to laryngeal and supralaryngeal components of vocalizations, and the integration of those cues can enable highly reliable caller identification. Our results demonstrate a clear acoustic basis by which individual macaque vocalizations can be recognized.

2013-06-01

Full Text Available Objectives: 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. Materials and Methods: 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.

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).

Rantala, Leena M; Hakala, Suvi; Holmqvist, Sofia; Sala, Eeva

2012-01-01

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.

Dissociation and psychosis in dissociative identity disorder and schizophrenia.

Laddis, Andreas; Dell, Paul F

2012-01-01

Dissociative symptoms, first-rank symptoms of schizophrenia, and delusions were assessed in 40 schizophrenia patients and 40 dissociative identity disorder (DID) patients with the Multidimensional Inventory of Dissociation (MID). Schizophrenia patients were diagnosed with the Structured Clinical Interview for the DSM-IV Axis I Disorders; DID patients were diagnosed with the Structured Clinical Interview for DSM-IV Dissociative Disorders-Revised. DID patients obtained significantly (a) higher dissociation scores; (b) higher passive-influence scores (first-rank symptoms); and (c) higher scores on scales that measure child voices, angry voices, persecutory voices, voices arguing, and voices commenting. Schizophrenia patients obtained significantly higher delusion scores than did DID patients. What is odd is that the dissociation scores of schizophrenia patients were unrelated to their reports of childhood maltreatment. Multiple regression analyses indicated that 81% of the variance in DID patients' dissociation scores was predicted by the MID's Ego-Alien Experiences Scale, whereas 92% of the variance in schizophrenia patients' dissociation scores was predicted by the MID's Voices Scale. We propose that schizophrenia patients' responses to the MID do not index the same pathology as do the responses of DID patients. We argue that neither phenomenological definitions of dissociation nor the current generation of dissociation instruments (which are uniformly phenomenological in nature) can distinguish between the dissociative phenomena of DID and what we suspect are just the dissociation-like phenomena of schizophrenia.

Voice and choice in health care in England: understanding citizen responses to dissatisfaction.

Science.gov (United States)

Dowding, Keith; John, Peter

2011-01-01

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.

Full Text Available Voice recognition technology is one of biometric technology. Sound is a unique part of the human being which made an individual can be easily distinguished one from another. Voice can also provide information such as gender, emotion, and identity of the speaker. This research will record human voices that pronounce digits between 0 and 9 with and without noise. Features of this sound recording will be extracted using Mel Frequency Cepstral Coefficient (MFCC. Mean, standard deviation, max, min, and the combination of them will be used to construct the feature vectors. This feature vectors then will be classified using Support Vector Machine (SVM. There will be two classification models. The first one is based on the speaker and the other one based on the digits pronounced. The classification model then will be validated by performing 10-fold cross-validation.The best average accuracy from two classification model is 91.83%. This result achieved using Mean + Standard deviation + Min + Max as features.

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.

2017-03-01

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.

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.

Ben Salem, Lobna

2011-01-01

Full Text Available In Assia Djebar’s war narratives, it is women’s voices and experiences that are at the centre of narration, in contrast to traditional male-centred narratives of war and conflict. In Fantasia,an Algerian Cavalcade, there are multiple female protagonists, survivors of independence war, who, through storytelling, present shifting perspectives and a multiplicity of voices that contest monological historical versions. By reassembling the fragments of individual identities, lost and forgotten by history, the writer forges collective identity, focussing on the communal rather thanprivate aspect of memory.The paper highlights the gender-specific nature of war memories; it examines the role of the narrative as a means of countering deficiencies of memory and combating historic amnesia.Centred on the idea that memory constructs identity, the paper investigates the extent to which a gendered memory of war can contribute in shaping collective identity, bearing in mind theinterdependence but also the dissonance of orality and texting.

Although there is a vast amount of research on leadership and improvement-oriented voice behavior, the amount of cross-lagged research on leadership that also incorporates more challenging forms of voice is sparse. This paper reports on a two-wave study of white-collar workers in a Norwegian...... medical technology company, investigating the relationship among employees’ perceived transformational leadership behaviors, job autonomy, and promotive and prohibitive voice. Testing our results cross-lagged, we demonstrate that perceived transformational leadership is significantly related...... to prohibitive voice over time, whereas this effect worked in the opposite direction for promotive voice. We also explore the boundary conditions of transformational leadership, demonstrating that perceived job autonomy strengthens the effect of transformational leadership on prohibitive voice.

Does phasic trauma treatment make patients with dissociative identity disorder treatment more dissociative?

Science.gov (United States)

Brand, Bethany; Loewenstein, Richard J

2014-01-01

Proponents of the iatrogenic model of the etiology of dissociative identity disorder (DID) have expressed concern that treatment focused on direct engagement and interaction with dissociated self-states harms DID patients. However, empirical data have shown that this type of DID treatment is beneficial. Analyzing data from the prospective Treatment of Patients With Dissociative Disorders (TOP DD) Study, we test empirically whether DID treatment is associated with clinically adverse manifestations of dissociated self-states: acting so differently that one feels like different people, hearing voices, and dissociative amnesia. We show that, over the course of the study, there were significant decreases in feeling like different people and hearing voices. These results indicate that this form of DID treatment does not lead to symptomatic worsening in these dimensions, as predicted by the iatrogenic model. Indeed, treatment provided by TOP DD therapists reduced, rather than increased, the extent to which patients experienced manifestations of pathological dissociation. Because severe symptomatology and impairment are associated with DID, iatrogenic harm may come from depriving DID patients of treatment that targets DID symptomatology.

Ikigai, H; Ono, T; Nakae, T; Otsuru, H; Shimamura, T

1999-01-08

Vibrio cholerae O1 grown in heart infusion broth produces two forms of El Tor hemolysin (ETH) monomers of 65 and 50 kDa. These monomers form several different sizes of mixed oligomers ranging from 180 to 280 kDa in the liposomal membranes. We found that the N-terminal amino acid sequences, NH2-Trp-Pro-Ala-Pro-Ala-Asn-Ser-Glu, of both the 65- and 50-kDa toxins were identical. We assumed, therefore, that the 65- and 50-kDa toxins were derivatives of the identical precursor protein and the 50-kDa protein was a truncated derivative of 65-kDa ETH. To substantiate this assumption, we treated the 260-kDa oligomer with trypsin and obtained a 190-kDa oligomer. This 190-kDa oligomer consisted of only the 50-kDa subunits. Both 260- and 190-kDa oligomers formed ion channels indistinguishable from each other in planar lipid bilayers. These results suggest that the essential part of the ETH in forming the membrane-damaging aggregate is a 50-kDa protein.

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 following radiotherapy

Stoicheff, M.L.

1975-01-01

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

Bele, Irene Velsvik

2007-05-01

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.

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.

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.

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

Competing for a citizen: “Visible” and “invisible” forms of state identity in Russia

Directory of Open Access Journals (Sweden)

Anna Sanina

2012-07-01

Full Text Available This paper is dedicated to the characteristics of phenomenon of state identity in the modern Russian society which has been affected for last 20 years by the processes of virtualization, informatization and political transformation. Today, the Russian Federation, like any other state in the world, is closely connected to non-local events and ideas; the “title nation” and “strong state” ideas are routinely confronted by challenges from multiple agents including immigrants, the mass media and especially the Internet. In the present study, empirical findings from several studies developed with methods of visual sociology, expert interviews and public opinion research are used to understand how people in Russia tend to realize their desire to be the unit of the state forming so-called “invisible” state identity, which is not absolutely loyal to the government institutions and is very stable. This type of identity has been formed under alternative institutional logic which isn't preordained by acting of the state but is shaped as well by cultural, social, and cognitive processes in “real”, but especially in “virtual” spaces of communication. And despite “Russia as a state” is still a way of maintaining the symbolic power of political leaders, there are some strong but hidden tendencies forming “Russia as a community of citizens” under the influence of information technologies, global values, norms and outlooks.

Learned voices of European citizens: from governmental to political subjectivation

Directory of Open Access Journals (Sweden)

Simons MAARTEN

2013-07-01

Full Text Available The article focuses on the way in which voice operates within the current discourse of democracy, citizenship, and learning. Based on an analysis of «learning devices» and «citizenship devices» we will show that the individual is asked to articulate him or herself in particular ways as evidence of engagement, of inclusion, and of participatory democracy. It is someone’s «personhood» –issues related to identity, preferences, feelings of ownership– that comes to count as evidence of civic engagement and political involvement. This process of personalization –the inscription of the individual as a person that turns him or her into a European citizen– will be described as an important aspect of the current mode of governmental subjectivation. To address this we explore, in line with Jacques Rancière, the notion of «political subjectivation». While governmental subjectivation involves a process of identification with the order of society, political subjectivation is a paradoxical process of deidentification with the social order. It is about the articulation of one’s voice as equal within a social order in which one has no voice according to the ruling organisation of positions.

Throw Yo' Voice Out: Disability as a Desirable Practice in Hip-Hop Vocal Performance

Directory of Open Access Journals (Sweden)

Alex S. Porco

2014-12-01

Full Text Available Disabled bodies and disabling spaces— especially the recording studio— shape the sound iconicity of hip-hop vocal performances. The disabled voice is the audible sign by which hip-hop artists trouble cultural definitions of the self and other; exceptionalism and failure; the natural and techno-mediated; comedy and tragedy; and aesthetic play and seriousness. Hip-hop vocal performances also function as self-conscious acts of transvaluation that challenge the discursive dominance of ableism. A materialist approach to vocal performance resists reducing voice to a silent metaphor for race, oppositionality, or liberation; and it emphasizes, instead, the physiological and social processes that render hip-hop voices unique, particular, and audible. It emphasizes the agency hip-hop artists possess in seeking out disabled bodies and assuming disabled identities for aesthetic and political ends. Thus, the body is returned to the analysis of style.

Voice Use Among Music Theory Teachers: A Voice Dosimetry and Self-Assessment Study.

Schiller, Isabel S; Morsomme, Dominique; Remacle, Angélique

2017-07-25

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.

2014-12-01

Full Text Available Issues of authenticity and identity are particularly significant in cities where social and cultural change is shaping active transformation of its urban fabric and structure in the post-war condition. In search of sustainable future, Iraqi cities are stretched between the two ends of the spectrum, authentic quarters with its traditional fabric and modern districts with their global sense of living. This paper interrogates the reciprocal influences and distinct qualities and sustainable performance of both authentic and modern quarters of Erbil, the capital of the Iraqi province of Kurdistan, as factors in shaping sustainable urban forms for Iraqi cities. In doing so, the paper, firstly, seeks to highlight the urban identity as an effective factor in relation to sustainable urban form. Secondly, the city of Erbil in Iraq has been chosen as a field study, due to its regional, social, political and historical role in the region. Thirdly, the study emphasises the dynamic activities and performance of residential projects according to rational sustainable criteria. The research concludes that urban identity and the sense of place in traditional and historical places should inform design strategies in order to achieve a more sustainable urban context.

Multilingual evaluation of voice disability index using pitch rate

Directory of Open Access Journals (Sweden)

Shuji Shinohara

2017-06-01

Full Text Available We propose the use of the pitch rate of free-form speech recorded by smartphones as an index of voice disability. This research compares the effectiveness of pitch rate, jitter, shimmer, and harmonic-to-noise ratio (HNR as indices of voice disability in English, German, and Japanese. Normally, the evaluation of these indices is performed using long-vowel sounds; however, this study included the recitation of a set passage, which is more similar to free-form speech. The results showed that for English, the jitter, shimmer, and HNR were very effective indices for long-vowel sounds, but the shimmer and HNR for read speech were considerably worse. Although the effectiveness of jitter as an index was maintained for read speech, the pitch rate was better in distinguishing between healthy individuals and patients with illnesses affecting their voice. The read speech results in German, Japanese, and English were similar, and the pitch rate showed the greatest efficiency for identification. Nevertheless, compared to English, the identification efficiency for the other two languages was lower.

2018-01-01

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.

Customer Protest: Exit, Voice or Negative Word of Mouth

Solvang, B. K.

2008-01-01

Full Text Available Of the three forms of protest the propensity of word of mouth (WOM seems to be the most common, and the most exclusive form of protest seems to be exit. The propensity for voice lies in between. The costs linked to voice influence the propensity for WOM. The customers seem to do an evaluation between the three forms of protest, yet the rational picture of the customers should be moderated.Leaders should improve their treatment of the customers making complaints. The more they can treat customer complaints in an orderly and nice way the less informal negative word of mouth activity they will experience and they will reduce the exit propensity and lead the customers to the complain organisation. They should also ensure that their customers feel they get equal treatment by the staff.

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

Science.gov (United States)

Hughes, Susan M; Harrison, Marissa A

2017-01-01

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

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

Directory of Open Access Journals (Sweden)

Zane Z Zheng

2011-04-01

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

Unfamiliar voice identification: Effect of post-event information on accuracy and voice ratings

Directory of Open Access Journals (Sweden)

Harriet Mary Jessica Smith

2014-04-01

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.

The Role of the Anonymous Voice in Post-Publication Peer Review Versus Traditional Peer Review

Directory of Open Access Journals (Sweden)

Jaime A. Teixeira da Silva

2015-12-01

Full Text Available Traditional peer review (TPR has several limitations and weaknesses. Post-publication peer review is one practical way to repair the ills of TPR and reinforce it. A literature that is marked by errors is unhealthy and should, if given the opportunity, be corrected or further improved. The anonymous voice is one source of critique and differs from the blind peer review in TPR in which the reviewer remains anonymous to the authors and/or vice versa, but the identity is known to the editor. If unregulated, the anonymous voice can pose a threat to established editorial norms in TPR, to one of the most important criteria of science publishing, i.e., transparency, and to worthwhile discussion. Yet, if the anonymous voice is not heard, then a vast and potentially valuable pool of untapped opinions may be lost, opinions that may provide valuable solutions to improving TPR.

Hammami, S.; Ben Saad, K.; Benrejeb, M.

2009-01-01

Using the Borne and Gentina practical criterion associated with the Benrejeb canonical arrow form matrix, to derive the stability property of dynamic complex systems, a new strategy of control is formulated for chaos synchronization of two identical Lorenz Stenflo systems and two new four-dimensional chaotic systems, namely the Qi chaotic systems. The designed controller ensures that the state variables of both controlled chaotic slave Lorenz Stenflo and Qi systems globally synchronizes with the state variables of the master systems, respectively. It is also shown that Qi system globally synchronizes with Lorenz Stenflo system under the afforded generalized strategy of control. Numerical simulations are carried out to assess the performance of the proposed contributions in the important field of chaotic synchronization.

A FRAMEWORK FOR INTELLIGENT VOICE-ENABLED E-EDUCATION SYSTEMS

Directory of Open Access Journals (Sweden)

Azeta A. A.

2009-07-01

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

It doesn't matter what you say: FMRI correlates of voice learning and recognition independent of speech content.

Zäske, Romi; Awwad Shiekh Hasan, Bashar; Belin, Pascal

2017-09-01

Listeners can recognize newly learned voices from previously unheard utterances, suggesting the acquisition of high-level speech-invariant voice representations during learning. Using functional magnetic resonance imaging (fMRI) we investigated the anatomical basis underlying the acquisition of voice representations for unfamiliar speakers independent of speech, and their subsequent recognition among novel voices. Specifically, listeners studied voices of unfamiliar speakers uttering short sentences and subsequently classified studied and novel voices as "old" or "new" in a recognition test. To investigate "pure" voice learning, i.e., independent of sentence meaning, we presented German sentence stimuli to non-German speaking listeners. To disentangle stimulus-invariant and stimulus-dependent learning, during the test phase we contrasted a "same sentence" condition in which listeners heard speakers repeating the sentences from the preceding study phase, with a "different sentence" condition. Voice recognition performance was above chance in both conditions although, as expected, performance was higher for same than for different sentences. During study phases activity in the left inferior frontal gyrus (IFG) was related to subsequent voice recognition performance and same versus different sentence condition, suggesting an involvement of the left IFG in the interactive processing of speaker and speech information during learning. Importantly, at test reduced activation for voices correctly classified as "old" compared to "new" emerged in a network of brain areas including temporal voice areas (TVAs) of the right posterior superior temporal gyrus (pSTG), as well as the right inferior/middle frontal gyrus (IFG/MFG), the right medial frontal gyrus, and the left caudate. This effect of voice novelty did not interact with sentence condition, suggesting a role of temporal voice-selective areas and extra-temporal areas in the explicit recognition of learned voice identity

Full Text Available Abstract Background The motor-driven predictions about expected sensory feedback (efference copies have been proposed to play an important role in recognition of sensory consequences of self-produced motor actions. In the auditory system, this effect was suggested to result in suppression of sensory neural responses to self-produced voices that are predicted by the efference copies during vocal production in comparison with passive listening to the playback of the identical self-vocalizations. In the present study, event-related potentials (ERPs were recorded in response to upward pitch shift stimuli (PSS with five different magnitudes (0, +50, +100, +200 and +400 cents at voice onset during active vocal production and passive listening to the playback. Results Results indicated that the suppression of the N1 component during vocal production was largest for unaltered voice feedback (PSS: 0 cents, became smaller as the magnitude of PSS increased to 200 cents, and was almost completely eliminated in response to 400 cents stimuli. Conclusions Findings of the present study suggest that the brain utilizes the motor predictions (efference copies to determine the source of incoming stimuli and maximally suppresses the auditory responses to unaltered feedback of self-vocalizations. The reduction of suppression for 50, 100 and 200 cents and its elimination for 400 cents pitch-shifted voice auditory feedback support the idea that motor-driven suppression of voice feedback leads to distinctly different sensory neural processing of self vs. non-self vocalizations. This characteristic may enable the audio-vocal system to more effectively detect and correct for unexpected errors in the feedback of self-produced voice pitch compared with externally-generated sounds.

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.

The sound of trustworthiness: Acoustic-based modulation of perceived voice personality.

Directory of Open Access Journals (Sweden)

Pascal Belin

Full Text Available When we hear a new voice we automatically form a "first impression" of the voice owner's personality; a single word is sufficient to yield ratings highly consistent across listeners. Past studies have shown correlations between personality ratings and acoustical parameters of voice, suggesting a potential acoustical basis for voice personality impressions, but its nature and extent remain unclear. Here we used data-driven voice computational modelling to investigate the link between acoustics and perceived trustworthiness in the single word "hello". Two prototypical voice stimuli were generated based on the acoustical features of voices rated low or high in perceived trustworthiness, respectively, as well as a continuum of stimuli inter- and extrapolated between these two prototypes. Five hundred listeners provided trustworthiness ratings on the stimuli via an online interface. We observed an extremely tight relationship between trustworthiness ratings and position along the trustworthiness continuum (r = 0.99. Not only were trustworthiness ratings higher for the high- than the low-prototypes, but the difference could be modulated quasi-linearly by reducing or exaggerating the acoustical difference between the prototypes, resulting in a strong caricaturing effect. The f0 trajectory, or intonation, appeared a parameter of particular relevance: hellos rated high in trustworthiness were characterized by a high starting f0 then a marked decrease at mid-utterance to finish on a strong rise. These results demonstrate a strong acoustical basis for voice personality impressions, opening the door to multiple potential applications.

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.

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

Familiar Person Recognition: Is Autonoetic Consciousness More Likely to Accompany Face Recognition Than Voice Recognition?

Science.gov (United States)

Barsics, Catherine; Brédart, Serge

2010-11-01

Autonoetic consciousness is a fundamental property of human memory, enabling us to experience mental time travel, to recollect past events with a feeling of self-involvement, and to project ourselves in the future. Autonoetic consciousness is a characteristic of episodic memory. By contrast, awareness of the past associated with a mere feeling of familiarity or knowing relies on noetic consciousness, depending on semantic memory integrity. Present research was aimed at evaluating whether conscious recollection of episodic memories is more likely to occur following the recognition of a familiar face than following the recognition of a familiar voice. Recall of semantic information (biographical information) was also assessed. Previous studies that investigated the recall of biographical information following person recognition used faces and voices of famous people as stimuli. In this study, the participants were presented with personally familiar people's voices and faces, thus avoiding the presence of identity cues in the spoken extracts and allowing a stricter control of frequency exposure with both types of stimuli (voices and faces). In the present study, the rate of retrieved episodic memories, associated with autonoetic awareness, was significantly higher from familiar faces than familiar voices even though the level of overall recognition was similar for both these stimuli domains. The same pattern was observed regarding semantic information retrieval. These results and their implications for current Interactive Activation and Competition person recognition models are discussed.

Mechanics of human voice production and control.

Zhang, Zhaoyan

2016-10-01

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.

The murga: voice and popular feeling

Franca Roibal Fernández

2016-03-01

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.

Speaker's voice as a memory cue.

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

2015-02-01

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

Investigating the neural correlates of voice versus speech-sound directed information in pre-school children.

Directory of Open Access Journals (Sweden)

Nora Maria Raschle

Full Text Available Studies in sleeping newborns and infants propose that the superior temporal sulcus is involved in speech processing soon after birth. Speech processing also implicitly requires the analysis of the human voice, which conveys both linguistic and extra-linguistic information. However, due to technical and practical challenges when neuroimaging young children, evidence of neural correlates of speech and/or voice processing in toddlers and young children remains scarce. In the current study, we used functional magnetic resonance imaging (fMRI in 20 typically developing preschool children (average age  = 5.8 y; range 5.2-6.8 y to investigate brain activation during judgments about vocal identity versus the initial speech sound of spoken object words. FMRI results reveal common brain regions responsible for voice-specific and speech-sound specific processing of spoken object words including bilateral primary and secondary language areas of the brain. Contrasting voice-specific with speech-sound specific processing predominantly activates the anterior part of the right-hemispheric superior temporal sulcus. Furthermore, the right STS is functionally correlated with left-hemispheric temporal and right-hemispheric prefrontal regions. This finding underlines the importance of the right superior temporal sulcus as a temporal voice area and indicates that this brain region is specialized, and functions similarly to adults by the age of five. We thus extend previous knowledge of voice-specific regions and their functional connections to the young brain which may further our understanding of the neuronal mechanism of speech-specific processing in children with developmental disorders, such as autism or specific language impairments.

2005-10-01

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

The results thus suggest that teachers with voice problems are more aware of classroom acoustic conditions than their healthy colleagues and make use of the more supportive rooms to lower their voice levels. This behavior may result from an adaptation process of the teachers with voice problems...... of the voice problems was made with a questionnaire and a laryngological examination. During teaching, the sound pressure level at the teacher’s position was monitored. The teacher’s voice level and the activity noise level were separated using mixed Gaussians.

Future generation automated human biometric identification and verification will require multiple features/sensors together with internal and external information sources to achieve high performance, accuracy, and reliability in uncontrolled environments. The primary objective of the proposed research is to develop a theoretical and practical basis for identifying and verifying people using standoff biometric features that can be obtained with minimal inconvenience during the verification process. The basic problem involves selecting sensors and discovering features that provide sufficient information to reliably verify a person's identity under the uncertainties caused by measurement errors and tactics of uncooperative subjects. A system was developed for discovering hand, face, ear, and voice features and fusing them to verify the identity of people. The system obtains its robustness and reliability by fusing many coarse and easily measured features into a near minimal probability of error decision algorithm

This research explores the linking mechanisms and conditional processes underlying the relationship between psychological voice climate and individual change readiness. In accordance with the social identity theory, we argued that normative commitment would mediate the relationship between psychological voice climate and individual change readiness; furthermore, work engagement would moderate the proposed indirect effect. Two-wave survey data were collected from 187 full-time employees in a government-owned institute of research and development and were adopted for moderated mediation analysis. The results showed that normative commitment mediates the relationship between psychological voice climate and individual change readiness. Furthermore, work engagement strengthens the effect of psychological voice climate on individual change readiness in an indirect manner via normative commitment. Based on the findings, the theoretical implications and practical suggestions were discussed. PMID:29062294

Acoustic passaggio pedagogy for the male voice.

Science.gov (United States)

Bozeman, Kenneth Wood

2013-07-01

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

Voice-to-Phoneme Conversion Algorithms for Voice-Tag Applications in Embedded Platforms

Directory of Open Access Journals (Sweden)

Yan Ming Cheng

2008-08-01

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.

We aimed at verifying an association between voice disorders/stress and loss of work ability among female teachers who work in São Paulo's public school system. This is a paired case- control study. The case group was composed offiteachers with alterations in speech and larynges assessments, and the control group was formed by teachers without alterations in these evaluations who work in the same schools. Both groups answered the following questionnaires: Conditions of Vocal Production-Teachers, Job Stress Scale, and Work Ability Index. The analysis was performed using the chi-square association test and logistic regression models with the purpose of estimating the association between independent variables and voice disorders. We found differences between the groups in relation to stress in the workplace under high demand, a situation that poses greater risks of adverse reactions to the workers' physical and mental health. Regarding the ability to work, the categories poor and moderate ability for work are associated with voice disorders, regardless of job stress factors, age, and the unsatisfactory acoustic properties of the classrooms. This study confirmed the association between voice disorders and job stress, as well as between voice disorders and loss of work ability.

The U-MICS is a self-report questionnaire designed to assess the identity dimensions from a domain-specific perspective. The present study reports on the development of a short-form version for the domains of job and romantic relationship in young adults from Germany and extends this scale to include the domain of region (n Sample1  = 95, 84% female, mean age 22.45 years; n Sample2  = 1,795, 71% female, mean age 24.53 years). We found the short form to possess adequate psychometric properties and to demonstrate a factor structure congruent to the long-form version. Regarding validity, the small correlations across domains within dimensions support a domain-specific approach to identity. The associations between the different identity domains with personality traits are similar, indicating a consistent pattern of convergent validity for all domains. We conclude that "region" provides a valuable complement to the established domains that can all be reliably assessed with the U-MICS-Short Form.

A complete understanding of nervous system function cannot be achieved without the identification of its component cell types. In this Perspective, we explore a series of related issues surrounding cell identity and how revolutionary methods for labeling and probing specific neuronal types have clarified this question. Specifically, we ask the following questions: what is the purpose of such diversity, how is it generated, how is it maintained, and, ultimately, how can one unambiguously identity one cell type from another? We suggest that each cell type can be defined by a unique and conserved molecular ground state that determines its capabilities. We believe that gaining an understanding of these molecular barcodes will advance our ability to explore brain function, enhance our understanding of the biochemical basis of CNS disorders, and aid in the development of novel therapeutic strategies.

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.

Enlightened Use of Passive Voice in Technical Writing

Science.gov (United States)

Trammell, M. K.

1981-01-01

The passive voice as a normal, acceptable, and established syntactic form in technical writing is defended. Passive/active verb ratios, taken from sources including 'antipassivist' text books, are considered. The suitability of the passive voice in technical writing which involves unknown or irrelevant agents is explored. Three 'myths' that the passive (1) utilizes an abnormal and artificial word order, (2) is lifeless, and (3) is indirect are considered. Awkward and abnormal sounding examples encountered in text books are addressed in terms of original context. Unattractive or incoherent passive sentences are explained in terms of inappropriate conversion from active sentences having (1) short nominal or pronominal subjects or (2) verbs with restrictions on their passive use.

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.

2016-01-01

The pitch-shift paradigm has become a widely used method for studying the role of voice pitch auditory feedback in voice control. This paradigm introduces small, brief pitch shifts in voice auditory feedback to vocalizing subjects. The perturbations trigger a reflexive mechanism that counteracts the change in pitch. The underlying mechanisms of the vocal responses are thought to reflect a negative feedback control system that is similar to constructs developed to explain other forms of motor ...

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.

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.

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

Luciana Iost Vinhas

2017-11-01

Full Text Available The Brazilian political moment in 2016 presents the opacity of the political discourse. The materialization of this discourse is produced in different forms of material existence. This study has as its objective to analyze Michel Temer’s voice, who was the Vice-President in Dilma Roussef’s Government. The analysis will focus on his first speech as Acting President. The analytical path of the study starts through the identification of the strangeness (ERNST, 2009 in the vocal materiality, which is understood as a discursive materiality with a different status: Michel’s voice produces an effect of failure in the ritual. We analyze, then, the sense effects produced by this sapped, choked voice, trying to relate it to the main interest in the French Discourse Analysis: the connection between ideology and unconsciousness.

In both a laboratory experiment (in Australia) using university as the basis of group membership, and a scenario experiment (in India) using religion as the basis of group membership, we observe more favourable respect and fairness ratings in response to an in-group authority than an out-group authority who administers non-instrumental voice. Moreover, we observe in our second experiment that reported likelihood of protest (herein called "social-change voice") was relatively high following non-instrumental voice from an out-group authority, but relatively low following non-instrumental voice from an in-group authority. Our findings are consistent with relational models of procedural justice, and extend the work by examining likely use of alternative forms of voice as well as highlighting the relative importance of instrumentality. ©2012 The British Psychological Society.

The self as subject autoethnographic research into identity, culture, and academic librarianship

Deitering, Anne-Marie; Stoddart, Richard

2017-01-01

Using autoethnography as their research method, the 21 academic librarian authors of The Self as Subject: Autoethnographic Research into Identity, Culture, and Academic Librarianship investigate aspects of what it means to be a librarian. Starting with a reflective examination of themselves, they each investigate questions of culture, values, and identity. The Self as Subject presents a collection of reflective narratives that, taken together, explore the varied dimensions of librarianship in the present moment. It also examines autoethnography's potential to help librarians answer questions that cannot be answered by traditional, empirical research methods and to reveal voices that are obscured by aggregations of data.

One (rating) from many (observations): Factors affecting the individual assessment of voice behavior in groups.

Science.gov (United States)

Podsakoff, Nathan P; Maynes, Timothy D; Whiting, Steven W; Podsakoff, Philip M

2015-07-01

This article reports an investigation into how individuals form perceptions of overall voice behavior in group contexts. More specifically, the authors examine the effect of the proportion of group members exhibiting voice behavior in the group, the frequency of voice events in the group, and the measurement item referent (group vs. individual) on an individual's ratings of group voice behavior. In addition, the authors examine the effect that measurement item referent has on the magnitude of the relationship observed between an individual's ratings of group voice behavior and perceptions of group performance. Consistent with hypotheses, the results from 1 field study (N = 220) and 1 laboratory experiment (N = 366) indicate that: (a) When group referents were used, raters relied on the frequency of voice events (and not the proportion of group members exhibiting voice) to inform their ratings of voice behavior, whereas the opposite was true when individual-referent items were used, and (b) the magnitude of the relationship between observers' ratings of group voice behavior and their perceptions of group performance was higher when raters used group-referent, as opposed to an individual-referent, items. The authors discuss the implications of their findings for scholars interested in studying behavioral phenomena occurring in teams, groups, and work units in organizational behavior research.

Arunachalam, Ravikumar; Boominathan, Prakash; Mahalingam, Shenbagavalli

2014-01-01

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

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 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.

Managing dysphonia in occupational voice users.

Behlau, Mara; Zambon, Fabiana; Madazio, Glaucya

2014-06-01

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.

Identifying hidden voice and video streams

Fan, Jieyan; Wu, Dapeng; Nucci, Antonio; Keralapura, Ram; Gao, Lixin

2009-04-01

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%.

Optical voice encryption based on digital holography.

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.

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.

Occupational risk factors and voice disorders.

Science.gov (United States)

Vilkman, E

1996-01-01

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.

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.

The Question of Identity in Gary Shteyngart’s Little Failure

Full Text Available In my paper I want to deal with the question of identity and Gary Shteyngart’s last novel, Little Failure (2014. The novel is a memoir that deals with young Gary’s struggle as an individual of Russian Jewish origins trying to accommodate himself to the American way of life. America with its multicultural and multiethnic environment puts the immigrant Gary in a very sensitive position. He does not know how to deal with African Americans; shall he avoid them or rim away? Shall he befriend Asian colleagues or not? Are Jewish friends more valuable than others? These are the questions that Gary Shteyngart has to answer and find his own voice. The protagonist of the novel under discussion tries to find his identity which is in continuous change. He tries to figure out in a world filled with cultural, racial and urban conflicts his own identity from the perspective of a former immigrant and as a member of a minority group. The task of my paper is to show how the question of identity has changed and what solution Shteyngart’s novel can offer for the protagonist in the process of identity formation.

Bottom-up influences of voice continuity in focusing selective auditory attention.

Science.gov (United States)

Bressler, Scott; Masud, Salwa; Bharadwaj, Hari; Shinn-Cunningham, Barbara

2014-01-01

Selective auditory attention causes a relative enhancement of the neural representation of important information and suppression of the neural representation of distracting sound, which enables a listener to analyze and interpret information of interest. Some studies suggest that in both vision and in audition, the "unit" on which attention operates is an object: an estimate of the information coming from a particular external source out in the world. In this view, which object ends up in the attentional foreground depends on the interplay of top-down, volitional attention and stimulus-driven, involuntary attention. Here, we test the idea that auditory attention is object based by exploring whether continuity of a non-spatial feature (talker identity, a feature that helps acoustic elements bind into one perceptual object) also influences selective attention performance. In Experiment 1, we show that perceptual continuity of target talker voice helps listeners report a sequence of spoken target digits embedded in competing reversed digits spoken by different talkers. In Experiment 2, we provide evidence that this benefit of voice continuity is obligatory and automatic, as if voice continuity biases listeners by making it easier to focus on a subsequent target digit when it is perceptually linked to what was already in the attentional foreground. Our results support the idea that feature continuity enhances streaming automatically, thereby influencing the dynamic processes that allow listeners to successfully attend to objects through time in the cacophony that assails our ears in many everyday settings.

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.

Full Text Available With almost five million English language learners in the United States, digital storytelling is increasingly being used in second language learning classrooms. As a teaching and learning strategy, digital storytelling can promote critical thinking, connect new content with prior knowledge, enhance memory, and foster confidence and motivation for learning. Digital stories possess unique narrative qualities that often center on identity negotiation and the ways culturally and linguistically diverse students make meaning out of their lives. Fostering hands-on, active learning, digital storytelling is an interactive way to include culturally and linguistically diverse students’ voices in a curriculum that may not easily represent them. Practical implementation of digital storytelling is included.

Hearing the unheard: An interdisciplinary, mixed methodology study of women’s experiences of hearing voices (auditory verbal hallucinations

Full Text Available This paper explores the experiences of women who ‘hear voices’ (auditory verbal hallucinations. We begin by examining historical understandings of women hearing voices, showing these have been driven by androcentric theories of how women’s bodies functioned, leading to women being viewed as requiring their voices be interpreted by men. We show the twentieth-century was associated with recognition that the mental violation of women’s minds (represented by some voice-hearing was often a consequence of the physical violation of women’s bodies. We next report the results of a qualitative study into voice-hearing women’s experiences (N=8. This found similarities between women’s relationships with their voices and their relationships with others and the wider social context. Finally, we present results from a quantitative study comparing voice-hearing in women (n=65 and men (n=132 in a psychiatric setting. Women were more likely than men to have certain forms of voice-hearing (voices conversing and to have antecedent events of trauma, physical illness, and relationship problems. Voices identified as female may have more positive affect than male voices. We conclude that women voice-hearers have and continue to face specific challenges necessitating research and activism, and hope this paper will act as a stimulus to such work.

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.

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.

2016-12-01

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

2016-11-01

Full Text Available The literacy experiences of Arab American youths are often overlooked in the US, and this paper examines the reading responses of one Arab 5th grader as he struggles for agency in a classroom of majority culture fellow students. This study follows the book talk of a class dealing with a text about immigration. Though he often struggles to contribute his perspective, as an actual immigrant himself, he is sometimes ignored and frustrated. This paper looks at this issue through Fairclough (2001 and van Dijk’s (1985, 2001 critical discourse lens, examining the intersectionality of racial, gender, and power issues in the microcosm of the literature study group. His cultural identity, perhaps a hybrid between the dominant US culture and his heritage Egyptian home culture, may manifest in such interactions. In a book discussion of Jane Kurtz’ Faraway Home, perhaps themes of the text mirror the student’s own struggles for belonging and search for identity in US society.

2008-01-01

Despite the fact that several studies have investigated the relationship between organizational citizenship behavior and performance appraisal ratings, the vast majority of these studies have been cross-sectional, correlational investigations conducted in organizational settings that do not allow researchers to establish the causal nature of this relationship. To address this lack of knowledge regarding causality, the authors conducted 2 studies designed to investigate the effects of task performance, helping behavior, voice, and organizational loyalty on performance appraisal evaluations. Findings demonstrated that each of these forms of behavior has significant effects on performance evaluation decisions and suggest that additional attention should be directed at both voice and organizational loyalty as important forms of citizenship behavior aimed at the organization. 2008 APA

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.

In most cases, about the voice of the patient with female-to-male/gender identity disorder (FTM/GID), hormone therapy makes the voice low-pitched. In success cases, there is no need for phonosurgery. However, hormone therapy is not effective in some cases. We perform type 3 thyroplasty in these cases. Hormone therapy was started in 2008 but did not lower the speaking fundamental frequencies (SFFs). We therefore performed TP3 under local anesthesia. In our case, the SFF at the first visit was 146 Hz. The postoperative SFF was 110 Hz. TP3 was performed under local anesthesia in a patient with FTM/GID in whom hormone therapy proved ineffective. With successful conversion to a lower-pitched voice, the patient could begin to live daily life as a male. QOL improved significantly with TP3. If hormone therapy proves ineffective, TP3 may be selected as an optional treatment and appears to show few surgical complications and was, in this case, a very effective treatment.

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.

[Hearing voices does not always constitute a psychosis].

Sommer, I E C; van der Spek, D W

2016-01-01

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.

Who do we think we are? Analysing the content and form of identity work in the English National Health Service.

McDermott, Imelda; Checkland, Kath; Harrison, Stephen; Snow, Stephanie; Coleman, Anna

2013-01-01

The language used by National Health Service (NHS) "commissioning" managers when discussing their roles and responsibilities can be seen as a manifestation of "identity work", defined as a process of identifying. This paper aims to offer a novel approach to analysing "identity work" by triangulation of multiple analytical methods, combining analysis of the content of text with analysis of its form. Fairclough's discourse analytic methodology is used as a framework. Following Fairclough, the authors use analytical methods associated with Halliday's systemic functional linguistics. While analysis of the content of interviews provides some information about NHS Commissioners' perceptions of their roles and responsibilities, analysis of the form of discourse that they use provides a more detailed and nuanced view. Overall, the authors found that commissioning managers have a higher level of certainty about what commissioning is not rather than what commissioning is; GP managers have a high level of certainty of their identity as a GP rather than as a manager; and both GP managers and non-GP managers oscillate between multiple identities depending on the different situations they are in. This paper offers a novel approach to triangulation, based not on the usual comparison of multiple data sources, but rather based on the application of multiple analytical methods to a single source of data. This paper also shows the latent uncertainty about the nature of commissioning enterprise in the English NHS.

Sprecher, Alicia; Olszewski, Aleksandra; Jiang, Jack J; Zhang, Yu

2010-06-01

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.

Acoustic cues for the recognition of self-voice and other-voice

Directory of Open Access Journals (Sweden)

Mingdi eXu

2013-10-01

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.

Measurement of voice onset time in maxillectomy patients.

2014-01-01

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.

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.

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.

Research purpose: The main aim of this study was to explore employee narratives and identify the strategies available to them in the process of identity work, as they defined themselves at work. Motivation for the study: As there is a scarcity of research on identity work in South Africa, this study wanted to advance knowledge about identity work and the strategies used for regulating and negotiating an identity at work by exploring these constructs in this context. Research design, approach and method: A qualitative research process formed the basis for this study. Nineteen employees from a global manufacturing company participated in two semi-structured in-depth interviews. Grounded theory was applied to analyse and interpret the data. Main findings: Nine strategies for identity work were identified and categorised into four broad themes (personal philosophies; relationships; career management and negotiating balance. Practical/managerial implications: Employees followed various strategies for defining themselves at work and this may have some implications for employee work engagement and productivity. Contribution/value-add: This study expands on current theoretical knowledge of identity work, and provides insights into the strategies people use to regulate and negotiate their identities at work.

Voice and choice by delegation.

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.

Singing Voice Analysis, Synthesis, and Modeling

Science.gov (United States)

Kim, Youngmoo E.

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

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.

How do you say 'hello'? Personality impressions from brief novel voices.

Science.gov (United States)

McAleer, Phil; Todorov, Alexander; Belin, Pascal

2014-01-01

On hearing a novel voice, listeners readily form personality impressions of that speaker. Accurate or not, these impressions are known to affect subsequent interactions; yet the underlying psychological and acoustical bases remain poorly understood. Furthermore, hitherto studies have focussed on extended speech as opposed to analysing the instantaneous impressions we obtain from first experience. In this paper, through a mass online rating experiment, 320 participants rated 64 sub-second vocal utterances of the word 'hello' on one of 10 personality traits. We show that: (1) personality judgements of brief utterances from unfamiliar speakers are consistent across listeners; (2) a two-dimensional 'social voice space' with axes mapping Valence (Trust, Likeability) and Dominance, each driven by differing combinations of vocal acoustics, adequately summarises ratings in both male and female voices; and (3) a positive combination of Valence and Dominance results in increased perceived male vocal Attractiveness, whereas perceived female vocal Attractiveness is largely controlled by increasing Valence. Results are discussed in relation to the rapid evaluation of personality and, in turn, the intent of others, as being driven by survival mechanisms via approach or avoidance behaviours. These findings provide empirical bases for predicting personality impressions from acoustical analyses of short utterances and for generating desired personality impressions in artificial voices.

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.

Can a voice disorder be an occupational disease?

Directory of Open Access Journals (Sweden)

Daša Gluvajić

2012-11-01

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

Through Thick and Thin: How Views of Identity Affect Listening for a Story in Portraiture

Directory of Open Access Journals (Sweden)

Laurie R. Matthias Ed.D.

2012-09-01

Full Text Available This article illustrates how different conceptions of narrative identity shape the ways that researchers listen for stories in the research approach of portraiture. To do so, we explore the methodological details of two portraiture studies, one on the integration of religious faith and learning among college professors and another on college student participation in hip-hop culture. In this exploration, we illustrate how psychosocial and storied resource perspectives of identity in each study shape the positioning of participant voices as resonant, dissonant, or excluded altogether. Overall, we look beyond issues of researcher reflexivity to elucidate one of the distinguishing features of portraiture and call for coherency between key constructs such as narrative identity and the different elements of qualitative research processes more generally.

The pattern of educator voice in clinical counseling in an educational hospital in Shiraz, Iran: a conversation analysis.

Kalateh Sadati, Ahmad; Bagheri Lankarani, Kamran

2017-01-01

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

Probing echoic memory with different voices.

Science.gov (United States)

Madden, D J; Bastian, J

1977-05-01

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

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.

Optimal dose-response relationships in voice therapy.

Science.gov (United States)

Roy, Nelson

2012-10-01

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".

A singer doesn’t just recite the lyrics of a song, but also with the use of particular sound techniques to make it more beautiful. In the singing technique, more female have a diverse sound registers than male. There are so many registers of the human voice, but the voice registers used while singing, among others, Chest Voice, Head Voice, Falsetto, and Vocal fry. Research of speech recognition based on the female’s voice registers in singing technique is built using Borland Delphi 7.0. Speech recognition process performed by the input recorded voice samples and also in real time. Voice input will result in weight energy values based on calculations using Hankel Transformation method and Macdonald Functions. The results showed that the accuracy of the system depends on the accuracy of sound engineering that trained and tested, and obtained an average percentage of the successful introduction of the voice registers record reached 48.75 percent, while the average percentage of the successful introduction of the voice registers in real time to reach 57 percent.

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

How to help teachers' voices.

Saatweber, Margarete

2008-01-01

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

Implicit multisensory associations influence voice recognition.

Directory of Open Access Journals (Sweden)

Katharina von Kriegstein

2006-10-01

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

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.

2012-05-01

This epidemiology study examined risk factors uniquely associated with spasmodic dysphonia (SD). Case-control. A questionnaire was administered to 150 patients with SD (with and without coexisting vocal tremor) and 136 patients with other structural, neurological, and functional voice disorders (excluding SD and vocal tremor). Questions included personal and family medical histories, environmental exposures, trauma, illnesses, voice use habits, and the Short Form 36. Several factors were uniquely associated with SD (α = .05), including: 1) a personal history of cervical dystonia, sinus and throat illnesses, mumps, rubella, dust exposure, and frequent volunteer voice use, 2) a family history of voice disorders, 3) an immediate family history of vocal tremor and meningitis, and 4) an extended family history of head and neck tremor, ocular disease, and meningitis. Vocal tremor coexisted with SD in 29% of cases. Measles and mumps vaccines were protective for SD. SD is likely multifactorial and associated with several endogenous and exogenous factors. Certain viral exposures, voice use patterns, and familial neurological conditions may contribute to the onset of SD later in life.

Voice and Speech Quality Perception Assessment and Evaluation

CERN Document Server

Jekosch, Ute

2005-01-01

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

Voice Disorders in Occupations with Vocal Load in Slovenia.

Boltežar, Lučka; Šereg Bahar, Maja

2014-12-01

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.

2007-04-01

This article describes a research project that investigated whether language barriers play a part in immigrant women's health decreasing when they move to Canada. The findings are then represented in the form of an ethnodrama entitled "ESL-Speaking Immigrant Women's Disillusions: Voices of Health Care in Canada." I suggest that the play is catalytic because it encourages target audiences to empathize with the silenced voices of ESL-speaking immigrant women who live in Canada. I then conclude with a reflection about the potential that the genre of ethnodrama has for social change through its reflexive and critical nature.

Voice restoration following total laryngectomy by tracheoesophageal prosthesis: Effect on patients' quality of life and voice handicap in Jordan

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.

It is definitely time for us to get used to the idea that mental space is not something impossible, unreal, but a different kind of reality. Moreover, the interdependance between the mind and the physical world cannot be dismissed as both physics and philosophy have demonstrated that one cannot exist without the other.This dissociative identity is mean to make up for an indiviual’sinability to express himself in the world in which he is living. The actor assumes this new identity in order to have his inner self from his personal failures and adops an image which gives him safety, surrounded by imaginary friends while looking for a family to provide a sense of fufillment.

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.

Common diagnoses and treatments in professional voice users.

Science.gov (United States)

Franco, Ramon A; Andrus, Jennifer G

2007-10-01

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.

Emotional Actions Are Coded Via Two Mechanisms: With And Without Identity

Directory of Open Access Journals (Sweden)

2016-05-01

Full Text Available Accurate perception of an individual’s identity and emotion derived from their actions and behavior is essential for successful social functioning. Here we determined the role of identity in the representation of emotional whole-body actions using visual adaptation paradigms. Participants adapted to actors performing different whole-body actions in a happy and sad fashion. Following adaptation subsequent neutral actions appeared to convey the opposite emotion. We demonstrate two different emotional action aftereffects showing distinctive adaptation characteristics. For one short-lived aftereffect, adaptation to the emotion expressed by an individual resulted in biases in the perception of the expression of emotion by other individuals, indicating an identity-independent representation of emotional actions. A second, longer lasting, aftereffect was observed where adaptation to the emotion expressed by an individual resulted in longer-term biases in the perception of the expressions of emotion only by the same individual; this indicated an additional identity-dependent representation of emotional actions. Together, the presence of these two aftereffects indicates the existence of two mechanisms for coding emotional actions, only one of which takes into account the actor’s identity. The results that we observe might parallel processing of emotion from face and voice.

Who's your neighbor? Acoustic cues to individual identity in red squirrel Tamiasciurus hudsonicus rattle calls

Directory of Open Access Journals (Sweden)

Shannon M. DIGWEED, Drew RENDALL, Teana IMBEAU

2012-10-01

Full Text Available North American red squirrels Tamiasciurus hudsonicus often produce a loud territorial rattle call when conspecifics enter or invade a territory. Previous playback experiments suggest that the territorial rattle call may indicate an invader's identity as squirrels responded more intensely to calls played from strangers than to calls played from neighbors. This dear-enemy effect is well known in a variety of bird and mammal species and functions to reduce aggressive interactions between known neighbors. However, although previous experiments on red squirrels suggest some form of individual differentiation and thus recognition, detailed acoustic analysis of potential acoustic cues in rattle calls have not been conducted. If calls function to aid in conspecific identification in order to mitigate aggressive territorial interactions, we would expect that individual recognition cues would be acoustically represented. Our work provides a detailed analysis of acoustic cues to identity within rattle calls. A total of 225 calls across 32 individual squirrels from Sheep River Provincial Park, Kananaskis, AB, Canada, were analyzed with discriminant function analysis for potential acoustic cues to individual identity. Initial analysis of all individuals revealed a reliable acoustic differentiation across individuals. A more detailed analysis of clusters of neighboring squirrels was performed and results again indicated a statistically significant likelihood that calls were assigned correctly to specific squirrels (55%-75% correctly assigned; in other words squirrels have distinct voices that should allow for individual identification and discrimination by conspecifics [Current Zoology 58 (5: 758–764, 2012].

Two-component network model in voice identification technologies

Edita K. Kuular

2018-03-01

Full Text Available Among the most important parameters of biometric systems with voice modalities that determine their effectiveness, along with reliability and noise immunity, a speed of identification and verification of a person has been accentuated. This parameter is especially sensitive while processing large-scale voice databases in real time regime. Many research studies in this area are aimed at developing new and improving existing algorithms for presentation and processing voice records to ensure high performance of voice biometric systems. Here, it seems promising to apply a modern approach, which is based on complex network platform for solving complex massive problems with a large number of elements and taking into account their interrelationships. Thus, there are known some works which while solving problems of analysis and recognition of faces from photographs, transform images into complex networks for their subsequent processing by standard techniques. One of the first applications of complex networks to sound series (musical and speech analysis are description of frequency characteristics by constructing network models - converting the series into networks. On the network ontology platform a previously proposed technique of audio information representation aimed on its automatic analysis and speaker recognition has been developed. This implies converting information into the form of associative semantic (cognitive network structure with amplitude and frequency components both. Two speaker exemplars have been recorded and transformed into pertinent networks with consequent comparison of their topological metrics. The set of topological metrics for each of network models (amplitude and frequency one is a vector, and together  those combine a matrix, as a digital "network" voiceprint. The proposed network approach, with its sensitivity to personal conditions-physiological, psychological, emotional, might be useful not only for person identification

Lamarche, Anick; Ternström, Sten; Pabon, Peter

2010-07-01

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

The Belt voice: Acoustical measurements and esthetic correlates

Science.gov (United States)

Bounous, Barry Urban

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

Goffi-Fynn, Jeanne C; Carroll, Linda M

2013-05-01

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

Multivariate sensitivity to voice during auditory categorization.

Lee, Yune Sang; Peelle, Jonathan E; Kraemer, David; Lloyd, Samuel; Granger, Richard

2015-09-01

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

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.

This study aims to evaluate the effects of voice rehabilitation with indwelling voice prosthesis on quality of life, depression, anxiety, self-esteem, and sexual functions in laryngectomy patients. Provox-1 was applied to 30 patients who underwent total laryngectomy by opening a tracheoesophageal fistula. WHO Quality of Life-BREF, Beck Depression Inventory, Beck Anxiety Inventory, Rosenberg Self-Esteem Scale, Arizona Sexual Experience Scale forms were asked to be filled out by the patients before voice prosthesis application. These tests were asked to be filled out again 3 months later after the voice prosthesis application. Paired samples and Wilcoxon tests were used to compare before and after operation values. Indwelling voice prosthesis was found to improve quality of life, self-esteem, and sexual function (p < 0.05). Additionally, symptoms of depression and anxiety were regressed (p < 0.05). Indwelling voice prosthesis was found to especially increase the quality of life and decrease depression (p < 0.05). This study is an uncontrolled single-arm study comparing patients' psychosocial statuses pre- and post-voice prosthesis.

Explaining the high voice superiority effect in polyphonic music: evidence from cortical evoked potentials and peripheral auditory models.

Science.gov (United States)

Trainor, Laurel J; Marie, Céline; Bruce, Ian C; Bidelman, Gavin M

2014-02-01

Natural auditory environments contain multiple simultaneously-sounding objects and the auditory system must parse the incoming complex sound wave they collectively create into parts that represent each of these individual objects. Music often similarly requires processing of more than one voice or stream at the same time, and behavioral studies demonstrate that human listeners show a systematic perceptual bias in processing the highest voice in multi-voiced music. Here, we review studies utilizing event-related brain potentials (ERPs), which support the notions that (1) separate memory traces are formed for two simultaneous voices (even without conscious awareness) in auditory cortex and (2) adults show more robust encoding (i.e., larger ERP responses) to deviant pitches in the higher than in the lower voice, indicating better encoding of the former. Furthermore, infants also show this high-voice superiority effect, suggesting that the perceptual dominance observed across studies might result from neurophysiological characteristics of the peripheral auditory system. Although musically untrained adults show smaller responses in general than musically trained adults, both groups similarly show a more robust cortical representation of the higher than of the lower voice. Finally, years of experience playing a bass-range instrument reduces but does not reverse the high voice superiority effect, indicating that although it can be modified, it is not highly neuroplastic. Results of new modeling experiments examined the possibility that characteristics of middle-ear filtering and cochlear dynamics (e.g., suppression) reflected in auditory nerve firing patterns might account for the higher-voice superiority effect. Simulations show that both place and temporal AN coding schemes well-predict a high-voice superiority across a wide range of interval spacings and registers. Collectively, we infer an innate, peripheral origin for the higher-voice superiority observed in human

The Stakeholder Model of voice research: Acknowledging barriers to human rights of all stakeholders in a communicative exchange.

Science.gov (United States)

Madill, Catherine; Warhurst, Samantha; McCabe, Patricia

2018-02-01

The act of communication is a complex, transient and often abstract phenomenon that involves many stakeholders, each of whom has their own perspective: the speaker, the listener, the observer and the researcher. Current research practices in voice disorder are frequently framed through a single lens - that of the researcher/clinician or their participant/patient. This single lens approach risks overlooking significant barriers to the basic human right of freedom of expression for those with a voice disorder as it omits consideration of the impact of voice disorder on the listener, and consideration of the wider impact of the voice in the occupational context. Recent research in the area of voice has developed a multiple lens and subsequent Stakeholder Model that acknowledges the experience and reality of multiple stakeholders viewing the same phenomenon, the voice. This research paradigm is built on Article 19 of the Universal Declaration of Human Rights as it considers the realities of all stakeholders in forming a deeper understanding of the causality, impact and aspects of communication disorder. The Stakeholder Model will be presented as a suggestion for future investigations of communication disorders more widely.

2003-06-01

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.

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.

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.

Raising voice, risking retaliation: Events following interpersonal mistreatment in the workplace.

Science.gov (United States)

Cortina, Lilia M; Magley, Vicki J

2003-10-01

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

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.

The rise and fall of gay: a cultural-historical approach to gay identity development.

Science.gov (United States)

Weststrate, Nic M; McLean, Kate C

2010-02-01

Research on identity development has paid relatively little attention to the development of marginalised identities such as those of gays and lesbians, whose isolation from the canonical narrative of sexuality may limit the available resources required for establishing a coherent identity. We examined these contested identities in relation to cultural-historical factors that may have played a role in shaping these identities over the past 50 years, and looked at how such factors have impacted the voicing and silencing of gay experiences. Participants (N=251) reported (1) a memory of a cultural event relevant to their sexuality, and (2) a self-defining memory about their sexuality. Those in older cohorts reported cultural memories centred on politics and other external events (e.g., Stonewall riots), and younger cohorts reported more personal memories (e.g., coming out), suggesting that homosexual identities have become less culturally defined, and instead more personally defined. Further, participants of older cohorts reported self-defining events that were predominantly from one private domain (e.g., sex). In contrast, younger participants reported a variety of self-defining events. These results suggest that cultural-historical factors play an important role in defining the developmental pathway of individuals, perhaps especially those who have marginalised identities.

Voice disorders in Nigerian primary school teachers.

Akinbode, R; Lam, K B H; Ayres, J G; Sadhra, S

2014-07-01

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.

Sensory Processing: Advances in Understanding Structure and Function of Pitch-Shifted Auditory Feedback in Voice Control

Directory of Open Access Journals (Sweden)

Charles R Larson

2016-02-01

Full Text Available The pitch-shift paradigm has become a widely used method for studying the role of voice pitch auditory feedback in voice control. This paradigm introduces small, brief pitch shifts in voice auditory feedback to vocalizing subjects. The perturbations trigger a reflexive mechanism that counteracts the change in pitch. The underlying mechanisms of the vocal responses are thought to reflect a negative feedback control system that is similar to constructs developed to explain other forms of motor control. Another use of this technique requires subjects to voluntarily change the pitch of their voice when they hear a pitch shift stimulus. Under these conditions, short latency responses are produced that change voice pitch to match that of the stimulus. The pitch-shift technique has been used with magnetoencephalography (MEG and electroencephalography (EEG recordings, and has shown that at vocal onset there is normally a suppression of neural activity related to vocalization. However, if a pitch-shift is also presented at voice onset, there is a cancellation of this suppression, which has been interpreted to mean that one way in which a person distinguishes self-vocalization from vocalization of others is by a comparison of the intended voice and the actual voice. Studies of the pitch shift reflex in the fMRI environment show that the superior temporal gyrus (STG plays an important role in the process of controlling voice F0 based on auditory feedback. Additional studies using fMRI for effective connectivity modeling show that the left and right STG play critical roles in correcting for an error in voice production. While both the left and right STG are involved in this process, a feedback loop develops between left and right STG during perturbations, in which the left to right connection becomes stronger, and a new negative right to left connection emerges along with the emergence of other feedback loops within the cortical network tested.

“The Voice as the Sound of Many Waters” in the Book of Revelation in Light of Old Testament Semantics: A Threatening Message or One of Beauty?

Directory of Open Access Journals (Sweden)

2017-03-01

Full Text Available The sentence ἡ φωνὴ αὐτοῦ ὡς φωνὴ ὑδάτων πολλῶν isn’t very commonly found in the Bible, despite the fact that the subject of God’s voice is one of the main motifs not only in the Old Testament. It’s used twice in Ezekiel and three times in the Book of Revelation. Both connect this motive with God to describe His Identity and deeds. The “many waters” do not only mean force, danger and terrible rule in the Bible. They are also a metaphor for abun-dance, which a good condition for progress, because water gives life. So “the voice as the sound of many waters” is the message of power, liveliness, beauty, and care. It’s so strong a voice that nobody and nothing is capable of overcoming it. Everybody who wants can hear it. It’s like the voice embraced from all sides. The Book of Revelation describes Jesus’ voice (Rev 1 : 15 and the voice from heaven (Rev 14 : 2 in such a way. Also for John, the mystery of internal experience (Rev 19 : 6 avoids any categorization. But for God, it’s the preferred way to communicate with human beings.

Assessments of Voice Use and Voice Quality among College/University Singing Students Ages 18–24 through Ambulatory Monitoring with a Full Accelerometer Signal

Schloneger, Matthew; Hunter, Eric

2016-01-01

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.

O'Connor, Jillian J M; Re, Daniel E; Feinberg, David R

2011-02-28

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.

Overgeneral autobiographical memory bias in clinical and non-clinical voice hearers.

2018-03-14

Hearing voices can be a distressing and disabling experience for some, whilst it is a valued experience for others, so-called 'healthy voice-hearers'. Cognitive models of psychosis highlight the role of memory, appraisal and cognitive biases in determining emotional and behavioural responses to voices. A memory bias potentially associated with distressing voices is the overgeneral memory bias (OGM), namely the tendency to recall a summary of events rather than specific occasions. It may limit access to autobiographical information that could be helpful in re-appraising distressing experiences, including voices. We investigated the possible links between OGM and distressing voices in psychosis by comparing three groups: (1) clinical voice-hearers (N = 39), (2) non-clinical voice-hearers (N = 35) and (3) controls without voices (N = 77) on a standard version of the autobiographical memory test (AMT). Clinical and non-clinical voice-hearers also completed a newly adapted version of the task, designed to assess voices-related memories (vAMT). As hypothesised, the clinical group displayed an OGM bias by retrieving fewer specific autobiographical memories on the AMT compared with both the non-clinical and control groups, who did not differ from each other. The clinical group also showed an OGM bias in recall of voice-related memories on the vAMT, compared with the non-clinical group. Clinical voice-hearers display an OGM bias when compared with non-clinical voice-hearers on both general and voices-specific recall tasks. These findings have implications for the refinement and targeting of psychological interventions for psychosis.

2016-11-01

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

Risk factors for voice quality after radiotherapy for early glottic cancer

International Nuclear Information System (INIS)

Hocevar-Boltezar, Irena; Zargi, Miha; Strojan, Primoz

2009-01-01

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.

To investigate the relationship between acoustic signal typing and perceptual evaluation of sustained vowels produced by tracheoesophageal (TE) speakers and the use of signal typing in the clinical setting. Two evaluators independently categorized 1.75-second segments of narrow-band spectrograms according to acoustic signal typing and independently evaluated the recording of the same segments on a visual analog scale according to overall perceptual acoustic voice quality. The relationship between acoustic signal typing and overall voice quality (as a continuous scale and as a four-point ordinal scale) was investigated and the proportion of inter-rater agreement as well as the reliability between the two measures is reported. The agreement between signal type (I-IV) and ordinal voice quality (four-point scale) was low but significant, and there was a significant linear relationship between the variables. Signal type correctly predicted less than half of the voice quality data. There was a significant main effect of signal type on continuous voice quality scores with significant differences in median quality scores between signal types I-IV, I-III, and I-II. Signal typing can be used as an adjunct to perceptual and acoustic evaluation of the same stimuli for TE speech as part of a multidimensional evaluation protocol. Signal typing in its current form provides limited predictive information on voice quality, and there is significant overlap between signal types II and III and perceptual categories. Future work should consider whether the current four signal types could be refined. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

2013-12-01

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.

Emotional Prosody Measurement (EPM): a voice-based evaluation method for psychological therapy effectiveness.

van den Broek, Egon L

2004-01-01

The voice embodies three sources of information: speech, the identity, and the emotional state of the speaker (i.e., emotional prosody). The latter feature is resembled by the variability of the F0 (also named fundamental frequency of pitch) (SD F0). To extract this feature, Emotional Prosody Measurement (EPM) was developed, which consists of 1) speech recording, 2) removal of speckle noise, 3) a Fourier Transform to extract the F0-signal, and 4) the determination of SD F0. After a pilot study in which six participants mimicked emotions by their voice, the core experiment was conducted to see whether EPM is successful. Twenty-five patients suffering from a panic disorder with agoraphobia participated. Two methods (story-telling and reliving) were used to trigger anxiety and were compared with comparable but more relaxed conditions. This resulted in a unique database of speech samples that was used to compare the EPM with the Subjective Unit of Distress to validate it as measure for anxiety/stress. The experimental manipulation of anxiety proved to be successful and EPM proved to be a successful evaluation method for psychological therapy effectiveness.

Benefits for Voice Learning Caused by Concurrent Faces Develop over Time.

Zäske, Romi; Mühl, Constanze; Schweinberger, Stefan R

2015-01-01

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.

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%.

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

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

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.

Full Text Available In Zimbabwe (like in most post-colonial African nations, history holds a critical place in discourses on constructions and reconstructions of national identity. The history of the Gukurahundi (the massacre of civilians in Matabeleland and Midlands regions of Zimbabwe in the early to late 1980s continues to dominate debates on the politics of ethnic exclusion in contemporary Zimbabwe. This article explores the place of creative fiction in this political discourse. The article contends that Yvonne Vera’s novel The Stone Virgins (which is set in the Gukurahundi era is a historically situated narrative of murder, rape, and trauma that powerfully challenges and renegotiates state power premised on hegemonic inscriptions and re-inscriptions of national history. The article focuses on the subtlety with which the psychic impact of rape and violence, especially as manifested in the suppression of the female victim’s voice and memory, can be read in turn (and paradoxically so as the novel’s complex attempt at speaking back to the political stifling of debate about the Gukurahundi. The focus on the political significance of representations of a woman’s voice and memory in The Stone Virgins is informed by the pervasive politicization and masculinization of voice and expression in post-2000 Zimbabwean politics.

Alexa, Siri, Cortana, and More: An Introduction to Voice Assistants.

Hoy, Matthew B

2018-01-01

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.

Form cues and content difficulty as determinants of children's cognitive processing of televised educational messages.

Science.gov (United States)

Campbell, T A; Wright, J C; Huston, A C

1987-06-01

An experiment was designed to assess the effects of formal production features and content difficulty on children's processing of televised messages about nutrition. Messages with identical content (the same script and visual shot sequence) were made in two forms: child program forms (animated film, second-person address, and character voice narration with sprightly music) and adult program forms (live photography, third-person address, and adult male narration with sedate background music). For each form, messages were made at three levels of content difficulty. Easier versions were longer, more redundant, and used simpler language; difficult versions presented information more quickly with less redundancy and more abstract language. Regardless of form or difficulty level, each set of bits presented the same basic information. Kindergarten children (N = 120) were assigned to view three different bits of the same form type and difficulty embedded in a miniprogram. Visual attention to child forms was significantly greater than to adult forms; free and cued recall scores were also higher for child than for adult forms. Although all recall and recognition scores were best for easy versions and worst for difficult versions, attention showed only minor variation as a function of content difficulty. Results are interpreted to indicate that formal production features, independently of content, influence the effort and level of processing that children use to understand televised educational messages.

Heidi Virkki

2008-01-01

Full Text Available Of the 30,000 children adopted yearly all over the world, about 200-300 come to Finland. A former adoption donor country, Finland started receiving international adoptees in the 1970s. Nowadays, there are about 3,000 internationally adopted persons in Finland. This paper focuses on the views and experiences of young Finnish international adoptees, who were interviewed during summer and autumn 2005. Altogether three group interviews and six individual interviews were carried out. The main aim was to study cultural identity and experiences of difference. The primary objective of this study is to give a voice to young international adoptees in Finland and present results as examples of how the dominant population adapts to difference.

Chilean earthquake and identity in the nerudian letter

Luis Rubilar Solís

2011-11-01

Full Text Available Given the geo-physic consistency of the narrow Chilean territory, extended between volcanoes and tectonic plates, the occurrence of natural catastrophes has been diachronic in its bicentennial existence as a nation. The oral as well as the written traditions have expressed this seismic nature as an ancestral ingredient of national identity. In Neruda's vital circumstances (1904-1973 four earthquakes took place, whose semiotic aftershocks resound in his writing. Noticing the telluric fate in this fi nis terrae, the poet's voice invites us to avoid mechanical and collective forgetfulness, warning us to install in the social imagination preventive attitudes to face futures disasters.

Guided self-help cognitive-behaviour Intervention for VoicEs (GiVE): Results from a pilot randomised controlled trial in a transdiagnostic sample.

2017-10-12

Few patients have access to cognitive behaviour therapy for psychosis (CBTp) even though at least 16 sessions of CBTp is recommended in treatment guidelines. Briefer CBTp could improve access as the same number of therapists could see more patients. In addition, focusing on single psychotic symptoms, such as auditory hallucinations ('voices'), rather than on psychosis more broadly, may yield greater benefits. This pilot RCT recruited 28 participants (with a range of diagnoses) from NHS mental health services who were distressed by hearing voices. The study compared an 8-session guided self-help CBT intervention for distressing voices with a wait-list control. Data were collected at baseline and at 12weeks with post-therapy assessments conducted blind to allocation. Voice-impact was the pre-determined primary outcome. Secondary outcomes were depression, anxiety, wellbeing and recovery. Mechanism measures were self-esteem, beliefs about self, beliefs about voices and voice-relating. Recruitment and retention was feasible with low study (3.6%) and therapy (14.3%) dropout. There were large, statistically significant between-group effects on the primary outcome of voice-impact (d=1.78; 95% CIs: 0.86-2.70), which exceeded the minimum clinically important difference. Large, statistically significant effects were found on a number of secondary and mechanism measures. Large effects on the pre-determined primary outcome of voice-impact are encouraging, and criteria for progressing to a definitive trial are met. Significant between-group effects on measures of self-esteem, negative beliefs about self and beliefs about voice omnipotence are consistent with these being mechanisms of change and this requires testing in a future trial.

Positive Relationship Between Individuality and Social Identity in Virtual Communities: Self-Categorization and Social Identification as Distinct Forms of Social Identity.

Science.gov (United States)

Guo, Tian-Chao; Li, Xuemei

2016-11-01

Previous studies have reported conflicting results regarding the relationship between individuality and social identity, indicating this area requires further examination. This study constructed a research model to help understand the positive role of individualized behavior and social identity in virtual communities. The results of an online survey conducted to assess our theoretical research model indicated that social identity can be expressed in two ways: self-categorization and social identification. Furthermore, we found individualized behavior was positively related to social identification, while self-categorization was directly derived from social identification.

Female EFL teachers: shifting and multiple gender and language-learner identities

Full Text Available Gender studies have taken an important role within the academic community, and specifically in the field of second and foreign languagelearning. In this paper I use a Feminist Poststructuralist Discourse Analysis (FPDA study to explore how emergent femininities construct genderidentities and power relations inside the EFL classroom setting through interaction. I argue that identities are multiple and shifting accordingto the way individuals position and reposition themselves through discourse(s. In doing so, gender identities can be identified and related tolearners’ identities in EFL contexts. I chose a Feminist Poststructuralist Discourse Analysis (FPDA methodology (Baxter, 2003 in order toidentify telling cases (Mitchell, 1984 during interactions in which, female adult students from a private university in Bogotá, Colombia makeexplicit the exercising of power during classroom activities, such as debates (Castañeda- Peña, 2009 and disputes (Toohey, 2001 in foreignlanguage learning. I chose video recordings, transcripts and interviews as instruments to cope with the objectives of the study as well as toaccomplish the methodological suggestions. Findings suggest the importance of being aware of the multiplicity of gender identities that mayintervene when learning a language and how to deal with more egalitarian discourses and activities during classes that guarantee, to someextent, the empowerment of silent voices.

Measurement errors in voice-key naming latency for Hiragana.

Science.gov (United States)

Yamada, Jun; Tamaoka, Katsuo

2003-12-01

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.

2012-10-01

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.

English Voicing in Dimensional Theory*

Science.gov (United States)

Iverson, Gregory K.; Ahn, Sang-Cheol

2007-01-01

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

Comparison of acoustic voice characteristics in smoking and nonsmoking teachers

Directory of Open Access Journals (Sweden)

Šehović Ivana

2012-01-01

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.

A Wireless LAN and Voice Information System for Underground Coal Mine

Directory of Open Access Journals (Sweden)

Yu Zhang

2014-06-01

Full Text Available In this paper we constructed a wireless information system, and developed a wireless voice communication subsystem based on Wireless Local Area Networks (WLAN for underground coal mine, which employs Voice over IP (VoIP technology and Session Initiation Protocol (SIP to achieve wireless voice dispatching communications. The master control voice dispatching interface and call terminal software are also developed on the WLAN ground server side to manage and implement the voice dispatching communication. A testing system for voice communication was constructed in tunnels of an underground coal mine, which was used to actually test the wireless voice communication subsystem via a network analysis tool, named Clear Sight Analyzer. In tests, the actual flow charts of registration, call establishment and call removal were analyzed by capturing call signaling of SIP terminals, and the key performance indicators were evaluated in coal mine, including average subjective value of voice quality, packet loss rate, delay jitter, disorder packet transmission and end-to- end delay. Experimental results and analysis demonstrate that the wireless voice communication subsystem developed communicates well in underground coal mine environment, achieving the designed function of voice dispatching communication.

Migration and Health in the Construction Industry: Culturally Centering Voices of Bangladeshi Workers in Singapore.

Science.gov (United States)

Dutta, Mohan J

2017-01-29

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health.

2014-11-01

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.

“I don’t know a lot of rude words”: Herbst, Paretsky, and Grafton’s Struggle to Master the Tough Guy Voice

Directory of Open Access Journals (Sweden)

Laura Ng

2013-09-01

Full Text Available Abstract The proletarian literature of the 1930s and traditional 1930s era hard-boiled detective fiction are literary siblings. Both genres came of age in popular publications. Both genres deal with establishing order. Both genres use the “tough guy” voice. This voice was a no-nonsense powerful tool used to highlight the gritty realism of blue collar life. This style of writing quickly became a central component for both genres. Embedded in the term “tough guy voice” is masculine identity. This is the voice for the active underdog male hero. Writing in genres for women is an on-going challenge given the expectation of gender implied in the narrative voice. For the contemporary feminist hard-boiled detective and the 1930’s women proletarian protagonist to be taken seriously in their respective tough guy genres, they must show the same verbal acumen as the male characters who built the genres. At the core of each genre, the expectation that tough guys remain tough guys is an issue that stretches beyond the time frame of 1930s and 1940s to contemporary iterations of the genres. The gendered transition from male protagonist to female protagonist requires authors like Josephine Herbst, Sara Paretsky, and Sue Grafton to engage in a series of dynamic manipulations verbal and textual manipulations. Both sets of authors created protagonists that faced the threat of being dismissed due to their gender, traditional family roles, and conflicts with authority. The authors dealt with these threats using very similar strategies, to varying levels of success. Paretsky and Grafton’s heroines win verbal battles by showing mastery of the voice and the other voices in the texts.  At the core of this struggle is the protagonists’ ability to maintain the power of professing.

Audiovisual speech facilitates voice learning.

Science.gov (United States)

Sheffert, Sonya M; Olson, Elizabeth

2004-02-01

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.

Who speaks for extinct nations? The Beothuk and narrative voice

Directory of Open Access Journals (Sweden)

C. Leggo

1995-04-01

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.

2012-10-01

Teaching is a high-risk occupation for developing voice disorders. The purpose of this study was to investigate previously described vocal risk factors as well as to identify new risk factors related to both the personal life of the teacher (fluid intake, voice-demanding activities, family history of voice disorders, and children at home) and to environmental factors (temperature changes, chalk use, presence of curtains, carpet, or air-conditioning, acoustics in the classroom, and noise in and outside the classroom). The study group comprised 994 teachers (response rate 46.6%). All participants completed a questionnaire. Chi-square tests and logistic regression analyses were performed. A total of 51.2% (509/994) of the teachers presented with voice disorders. Women reported more voice disorders compared to men (56.4% versus 40.4%, P history of voice disorders (P = 0.005), temperature changes in the classroom (P = 0.017), the number of pupils per classroom (P = 0.001), and noise level inside the classroom (P = 0.001). Teachers with voice disorders presented a higher level of psychological distress (P < 0.001) compared to teachers without voice problems. Voice disorders are frequent among teachers, especially in female teachers. The results of this study emphasize that multiple factors are involved in the development of voice disorders.

Full Text Available The starting point is the principle that there is no immigrant culture, but rather, different ways of living, coexisting and identifying oneself within the cultural worlds that each subject crosses on his or her social path. Here we study Brazilian immigrants in Portugal, working with the first wave (starting at the end of the 1980s and the second wave (at the turn of the 20th to 21st century. We intend, firstly, to show how identity is reconstructed between two banks: the departure culture and the arrival culture. Secondly, we intend to give a voice to the most silent in the understanding of immigrants: the process of identity reconstruction of Brazilian immigrants is presented, resulting from ethno-biographic interviews. We will consider the cultural transfusion theory and observe the heterogeneous ways of living between cultures, whether by rejecting the departure culture (the Oblato‘s case, refusing the arrival one at a given moment (the mono-cultural subject according to the source culture, living in an ambivalent manner between the two (the multicultural self, or, finally, inventing a third bank, as the poets say, which corresponds to an attitude of including the cultural differences through which one crosses during his or her life history in an intercultural self (the Intercultural Transfuga.

Risk in Postgraduate Writing: Voice, Discourse and Edgework

Directory of Open Access Journals (Sweden)

Lucia Thesen

2013-11-01

Full Text Available This paper brings writing into the contested space of research and knowledge-making in South Africa. An often hidden dimension of research is that it has to find expression in a written product, increasingly in English. This creates challenges for both students, who have developed writing identities in other domains, disciplines and languages, and also supervisors and journal editors who are gatekeepers for the making of new knowledge. In a competitive and uncertain climate where discourses of risk management play an increasingly important part, people tend to play it safe when it comes to writing, conforming to a narrow image of scientific writing. This has consequences for knowledge-making as students often set aside the experiences, allegiances and styles they have developed along the way. Drawing on data from an international publishing project on risk in academic writing, the paper explores dilemmas around the process of research writing. These instances make the contradictions and tensions faced by writers and gatekeepers central, highlighting the importance of voice and risk. Both voice and risk are explored experientially and theoretically, with the emphasis on the potentials of risk. The concept of risk, not as risk management, but as risk-taking, offers new ways of thinking about writing that brings the decisions that writers and readers make to the fore. A focus on risk has the potential to offer new understandings about the changing landscapes in which writers and readers weigh up their options against notions of what is ‘normal’.  Finally I suggest edgework as a productive concept that can take work on risk forward in both research and pedagogy.

Full Text Available This research aims at describing 1 stages of homosexual identity development in three main characters in the Rainbow Trilogy using Cass model, 2 factors influencing the development of homosexual identity using D Augellis theory, and 3 forms of victimization towards homosexuals experienced by the main characters using theories of D Augelli and Rivers. Queer studies was applied to describe and analyze the data in forms of words, phrases, sentences, statements, dialogues as well as monologues in the Rainbow Trilogy, recording thoughts and actions by the characters in accordance with the research focus. As a result, the research finds out that the three novels describe clearly all stages of Cass model of homosexual identity development in Jason and Kyle, including their identity confusions, comparisons, acceptances, tolerances, prides and syntheses. In Nelson, only one stage that can be identified as Nelson is described as one whose sexual identity has been formed. The research also reveals how factors of personal subjectivity and action, interactive intimacy and sociohistorical connection are connected to each others and also influencing the homosexual identity developments of the main characters. Besides, the research also shows that various kinds of victimization occur to Jason, Kyle and Nelson. Normative victimizations made to feel different are experienced by Nelson and Kyle. Family stressor and prejudices in connection to AIDS are experienced by the three characters. Victimization of direct attacks in forms of verbal and physical abuses are experienced by Kyle and Nelson. Lastly, the research finds out that Nelson is the only character experiencing sexual abuse. It occurs in form of undesired comments oriented to a sexual violence.

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.

Health care has a number of historical barriers to capturing the voice of the customer and to incorporating customer wants into health care services, whether the customer is a patient, an insurer, or a community. Quality function deployment (QFD) is a set of tools and practices that can help overcome these barriers to form a process for the planning and design or redesign of products and services. The goal of the project was to increase referral volume and to improve a rehabilitation hospital's capacity to provide comprehensive medical and/or legal evaluations for people with complex and catastrophic injuries or illnesses. HIGH-LEVEL VIEW OF QFD AS A PROCESS: The steps in QFD are as follows: capture of the voice of the customer, quality deployment, functions deployment, failure mode deployment, new process deployment, and task deployment. The output of each step becomes the input to a matrix tool or table of the next step of the process. In 3 1/2 months a nine-person project team at Continental Rehabilitation Hospital (San Diego) used QFD tools to capture the voice of the customer, use these data as the basis for a questionnaire on important qualities of service from the customer's perspective, obtain competitive data on how the organization was perceived to be meeting the demanded qualities, identify measurable dimensions and targets of these qualities, and incorporate the functions and tasks into the delivery of service which are necessary to meet the demanded qualities. The future of providing health care services will belong to organizations that can adapt to a rapidly changing environment and to demands for new products and services that are produced and delivered in new ways.

Trends in Singing Voice Research: An Innovative Approach.

Pestana, Pedro Melo; Vaz-Freitas, Susana; Manso, Maria Conceição

2018-01-11

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

The effectiveness of HIV pre-exposure prophylaxis (PrEP) requires consistent and correct product use, thus a deeper understanding of women's stated product formulation preferences, and the correlates of those preferences, can help guide future research. VOICE-D (MTN-003D), a qualitative ancillary study conducted after the VOICE trial, retrospectively explored participants' tablet and gel use, as well as their preferences for other potential PrEP product formulations. We conducted an analysis of quantitative and qualitative data from VOICE-D participants. During in-depth interviews, women were presented with pictures and descriptions of eight potential PrEP product formulations, including the oral tablet and vaginal gel tested in VOICE, and asked to discuss which product formulations they would prefer to use and why. Seven of the original product formulations displayed were combined into preferred product formulation categories based on exploratory factor and latent class analyses. We examined demographic and behavioural correlates of these preferred product formulation categories. In-depth interviews with participants were conducted, coded, and analysed for themes related to product preference. Of the 68 female participants who completed in-depth interviews (22 South Africa, 24 Zimbabwe, 22 Uganda), median age was 28 (range 21-41), 81% were HIV negative, and 49% were married or living with a partner. Four preferred product formulation categories were identified via exploratory factor analysis: 1) oral tablets; 2) vaginal gel; 3) injectable, implant, or vaginal ring; and 4) vaginal film or suppository. A majority of women (81%) expressed a preference for product formulations included in category 3. Characteristics significantly associated with each preferred product category differed. Attributes described by participants as being important in a preferred product formulation included duration of activity, ease of use, route of administration, clinic- versus self

Discriminating male and female voices: differentiating pitch and gender.

Science.gov (United States)

Latinus, Marianne; Taylor, Margot J

2012-04-01

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.

Student voice: An emerging discourse in Irish education policy

Directory of Open Access Journals (Sweden)

Domnall Fleming

2015-09-01

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.

Self, William T.; Mitchell, Gregory; Mellers, Barbara A.; Tetlock, Philip E.; Hildreth, J. Angus D.

2015-01-01

This study compared two forms of accountability that can be used to promote diversity and fairness in personnel selections: identity-conscious accountability (holding decision makers accountable for which groups are selected) versus identity-blind accountability (holding decision makers accountable for making fair selections). In a simulated application screening process, undergraduate participants (majority female) sorted applicants under conditions of identity-conscious accountability, identity-blind accountability, or no accountability for an applicant pool in which white males either did or did not have a human capital advantage. Under identity-conscious accountability, participants exhibited pro-female and pro-minority bias, particularly in the white-male-advantage applicant pool. Under identity-blind accountability, participants exhibited no biases and candidate qualifications dominated interview recommendations. Participants exhibited greater resentment toward management under identity-conscious accountability. PMID:26660723

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.

Migration and Health in the Construction Industry: Culturally Centering Voices of Bangladeshi Workers in Singapore

Science.gov (United States)

Dutta, Mohan J.

2017-01-01

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health. PMID:28146056

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.

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.

Orlova, O S; Vasilenko, Iu S; Zakharova, A F; Samokhvalova, L O; Kozlova, P A

2000-01-01

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

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

Adolescence and emerging adulthood are periods in life when individuals both question and define their place in society and form their identity. Meanwhile, active youth civic engagement represents a challenge for each democracy. The purpose of this study was to analyze the different forms of civic engagement among late adolescents and emerging adults and how they are related to personal identity and social identity, while adopting an integrative perspective through the lens of a person-oriented approach. The participants were 1217 (62.3% female) 16-24 year-old French students (M age  = 19.17; SD age  = 1.83). First, derived from cluster analyses, the findings emphasized diversity in civic engagement, from strong civic participation (in different formal and informal ways) to various forms of passivity. Diversity was also highlighted for personal identity and social identity profiles. Second, a Configural Frequency Analysis revealed a typical pattern associating passivity in civic engagement, personal carefree diffusion and rejection of social identity. Overall, these findings highlight an absence of general youth disaffection and provide a meaningful specific pattern for the understanding of passivity in political and civic matters in late adolescence and emerging adulthood.

Voice Disorder Classification Based on Multitaper Mel Frequency Cepstral Coefficients Features

Ömer Eskidere

2015-01-01

Full Text Available The Mel Frequency Cepstral Coefficients (MFCCs are widely used in order to extract essential information from a voice signal and became a popular feature extractor used in audio processing. However, MFCC features are usually calculated from a single window (taper characterized by large variance. This study shows investigations on reducing variance for the classification of two different voice qualities (normal voice and disordered voice using multitaper MFCC features. We also compare their performance by newly proposed windowing techniques and conventional single-taper technique. The results demonstrate that adapted weighted Thomson multitaper method could distinguish between normal voice and disordered voice better than the results done by the conventional single-taper (Hamming window technique and two newly proposed windowing methods. The multitaper MFCC features may be helpful in identifying voices at risk for a real pathology that has to be proven later.

Full Text Available The article discusses the role of historical narratives in the formation of identity. Rüsen’s thesis on the contradiction of traditional historical identities that suggest an ethnocentric position with the processes of intercultural communication is analyzed. The potential of historical narratives in overcoming (or restricting ethnocentrism is considered. It is shown that ethnocentrism is constituted by kinds of the configuration of historical writing rather than by a subjective position of historical narrative authors. The types of stories suggest a the way of making history using only the criteria of success and failure in the interpretation of the past; b interpretation of history as teleological continuity; c merely the necessity to justify (to substantiate claims or to discredit something. It is alleged that the realization that the form of historical knowledge constructs, not discovers, can facilitate liberation from referential fallacy on the whole and enslavement by certain kinds of stories in particular. It is concluded that the recognition of the constitutive nature of historical narratives allows being independent from the traditional forms of historical knowledge and traditional ideas about their cultural value. In particular, it allows reconsidering the need to apply historical knowledge when constructing identity.

Reiter, R; Brosch, S

2008-05-01

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.

Co-creating Polyphony or Cacophony? A case study of an organization’s current brand co-creation process and the challenge of integrating multiple voices

DEFF Research Database (Denmark)

Schmeltz, Line; Kjeldsen, Anna Karina

The latest wave within branding theory suggests a move toward enterprise branding or co-created branding (cf. Hatch and Schultz, 2010; Johansen and Andersen, 2012; Karmark, 2013). This entails that organizations to a large extent involve both external and internal stakeholders in an ongoing......, dynamic process of creating and developing the corporate brand. In theory, this approach holds great promise in terms of increasing organizational transparency, creating stakeholder engagement, as well as true stakeholder dialogue. But, a brand co-creation process also exposes the organization to danger......, e.g. loss of control, dilution of identity, and potential disharmony between the multiple voices co-creating the brand. Therefore, this paper empirically explores how an organization endeavoring into a brand co-creation process struggles to orchestrate the many voices in practice. Implications focus...

The mean duration of voice rest was 8.8 days (range, 3-28), and the median was 7 days. Overall compliance was 34.5%. Postoperative voice rest patients were more compliant than non-postoperative patients (42.4% vs 16.0%, P = .04, χ(2)). Voice rest had an impact on QOL (mean ± SD, 68.5 ± 27.7). Voice rest also had a greater impact on singers than nonsingers (mean VAS 77.2 vs 63.6, P = .03, t test) and on those age <60 years than those age ≥ 60 years (mean VAS 74.4 vs 46.7, P < .001, t test). More talkative patients and those with longer periods of voice rest had worse QOL scores (Spearman correlation = 0.35, P = .001 and Spearman correlation = 0.24, P = .03, respectively). Restrictions in personal and social life were noted in 36.9% of patients, 46.4% were unable to work, 44.0% felt frustrated, and 38.1% reported feeling handicapped while on voice rest. Given poor patient compliance and the significant impact of voice rest on QOL, further studies are warranted to examine the efficacy of voice rest and factors that may contribute to patient noncompliance with treatment.

Computerized detection of voice disorders has attracted considerable academic and clinical interest in the hope of providing an effective screening method for voice diseases before endoscopic confirmation. This study proposes a deep-learning-based approach to detect pathological voice and examines its performance and utility compared with other automatic classification algorithms. This study retrospectively collected 60 normal voice samples and 402 pathological voice samples of 8 common clinical voice disorders in a voice clinic of a tertiary teaching hospital. We extracted Mel frequency cepstral coefficients from 3-second samples of a sustained vowel. The performances of three machine learning algorithms, namely, deep neural network (DNN), support vector machine, and Gaussian mixture model, were evaluated based on a fivefold cross-validation. Collective cases from the voice disorder database of MEEI (Massachusetts Eye and Ear Infirmary) were used to verify the performance of the classification mechanisms. The experimental results demonstrated that DNN outperforms Gaussian mixture model and support vector machine. Its accuracy in detecting voice pathologies reached 94.26% and 90.52% in male and female subjects, based on three representative Mel frequency cepstral coefficient features. When applied to the MEEI database for validation, the DNN also achieved a higher accuracy (99.32%) than the other two classification algorithms. By stacking several layers of neurons with optimized weights, the proposed DNN algorithm can fully utilize the acoustic features and efficiently differentiate between normal and pathological voice samples. Based on this pilot study, future research may proceed to explore more application of DNN from laboratory and clinical perspectives. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc.

Full Text Available The civic identity of an individual is seen as a dynamic system of citizen's perceptions of himself / herself and related emotions and value-semantic elements derived from the awareness of the fact that he / she is a citizen of a state and at the same time a member of the community of citizens. The results of the study support the notion that awareness of being a citizen of the state does not already mean having civic identity. Only 34% of interviewed students have a well-formed positive civic identity; 37% are showing some uncertainty, vagueness, ambiguity in their perception of themselves as citizens; 15% reject their Ukrainian civic identity, have a well-formed negative civic identity, and, more than other types, exhibit passive-indifferent civil position; 14% make a group of "potential emigrants" who are ready to change the Ukrainian civic identity for another. The differences in worldview and value-motivational sphere of students with the formed positive ("reached", undefined ("indistinct" / "diffuse", formed negative ("negative-passive" and "protest" ("potential immigrants" civic identity have been discovered.

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.

When dual identity becomes a liability: identity and political radicalism among migrants.

2013-03-01

This article examines the role of dual identity in political radicalism among migrants. Dual identity is defined as identification with both one's ethnocultural minority in-group and one's society of residence. We employed a longitudinal research design using members of the two largest migrant groups in Germany (Turkish migrants and Russian migrants) as participants. We reasoned that when dual identity is burdened with incompatibility between component identifications, it may foster controversial or even destructive forms of political mobilization, such as radicalism. Multiple regression analysis controlling for other influences confirmed the hypothesized moderated relationship between dual identification and sympathy for radical action. When accompanied by high, as opposed to low, perceived identity incompatibility, dual identification predicted increases in sympathy for radical action among both Turkish migrants and Russian migrants. The implications for public life in ethnically and culturally heterogeneous societies are discussed.

ATC/pilot voice communications: A survey of the literature

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.

2016-07-01

In clinical settings, there is substantial evidence both clinically and empirically to suggest that approximately 50% of individuals with borderline personality disorder experience auditory verbal hallucinations. However, there is limited research investigating the phenomenology of these voices. The aim of this study was to review and compare our current understanding of auditory verbal hallucinations in borderline personality disorder with auditory verbal hallucinations in patients with a psychotic disorder, to critically analyse existing studies investigating auditory verbal hallucinations in borderline personality disorder and to identify gaps in current knowledge, which will help direct future research. The literature was searched using the electronic database Scopus, PubMed and MEDLINE. Relevant studies were included if they were written in English, were empirical studies specifically addressing auditory verbal hallucinations and borderline personality disorder, were peer reviewed, used only adult humans and sample comprising borderline personality disorder as the primary diagnosis, and included a comparison group with a primary psychotic disorder such as schizophrenia. Our search strategy revealed a total of 16 articles investigating the phenomenology of auditory verbal hallucinations in borderline personality disorder. Some studies provided evidence to suggest that the voice experiences in borderline personality disorder are similar to those experienced by people with schizophrenia, for example, occur inside the head, and often involved persecutory voices. Other studies revealed some differences between schizophrenia and borderline personality disorder voice experiences, with the borderline personality disorder voices sounding more derogatory and self-critical in nature and the voice-hearers' response to the voices were more emotionally resistive. Furthermore, in one study, the schizophrenia group's voices resulted in more disruption in daily functioning

Robotics as science (re)form: Exploring power, learning and gender(ed) identity formation in a "community of practice"

Science.gov (United States)

Hurner, Sheryl Marie

"Robotics as Science (re)Form" utilizes qualitative research methods to examine the career trajectories and gender identity formation of female youth participating as members of an all-girl, academic team within the male-dominated environment of the FIRST Robotics competition. Following the constant comparative approach (Glaser & Strauss, 1967), my project relies upon triangulating ethnographic data drawn from extensive field notes, semi-structured interviews, and digital and video imagery compiled over two years of participant observation. Drawing upon the sociolinguistic "community of practice" (CoP) framework (Eckert & McConnell-Ginet, 1992; Lave & Wenger, 1991; Wenger, 1998), this study maps the range of gendered "identities" available to girls involved in non-traditional academic and occupational pursuits within a local context, and reveals the nature, structure and impact of power operating within this CoP, a significantly underdeveloped construct within the language and gender literature. These research findings (1) contribute to refining theories of situated or problem based learning with a focus on female youth (Lave & Wenger, 1991; Wenger, 1998); (2) reveal affordances and barriers within the local program design that enable (and preclude) women and minority youth entering the engineering pipeline; and (3) enrich our understanding of intragroup language and gendered "practices" to counter largely essentializing generalizations based upon quantitative analysis.

The voices of newcomers. A qualitative analysis of the construction of transnationalidentity

Directory of Open Access Journals (Sweden)

2015-04-01

Full Text Available Nowadays, globalization is connected with the emergence and reconstruction of new identities. Forinstance, the migration process implies the generation of new forms of identity, questioning the traditionalhomogeneous and static notions of identity. In this regard, the term "transnational identity" or "biculturalidentity" has been suggested for these people that live in between two cultural frameworks and has toestablish a dialogue between the country of origin ("there" and the host country ("here". This studyshows the bicultural and multiple nature of ten immigrant life stories. These narratives illustrate howbicultural and multilingual skills become part of the self definition through the appropriation of culturalvoices that manage the origin and host lifestyles, building hybrid and multiple identities that preservecertain ties with the origin society and take certain forms of life of the new culture and society. The noveltyembodied in this work is the qualitative approach taken in the research. Most of the literature ontransnational identity and transnationalism are based on theoretical discussions or quantitative data.

It's tough to imagine anything more frustrating than interacting with a call center. Generally, people don't reach out to call centers when they?re happy-they're usually trying to get help with a problem or gearing up to do battle over a billing error. Add in an automatic phone tree, and you have a recipe for annoyance. But what if that robotic voice offering you a smorgasbord of numbered choices could tell that you were frustrated and then funnel you to an actual human being? This type of voice analysis technology exists, and it's just one example of the many ways that computers can use your voice to extract information about your mental and emotional state-including information you may not think of as being accessible through your voice alone.

Speaker-Sex Discrimination for Voiced and Whispered Vowels at Short Durations.

Science.gov (United States)

Smith, David R R

2016-01-01

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 performance would improve relative to whispered vowel performance as pitch information becomes available. This pattern of results was shown for women's but not for men's voices. A whispered vowel needs to have a duration three times longer than a voiced vowel before listeners can reliably tell whether it's spoken by a man or woman (∼30 ms vs. ∼10 ms). Listeners were half as sensitive to information about speaker-sex when it is carried by whispered compared with voiced vowels.

A Robust Multimodal Bio metric Authentication Scheme with Voice and Face Recognition

International Nuclear Information System (INIS)

Kasban, H.

2017-01-01

This paper proposes a multimodal biometric scheme for human authentication based on fusion of voice and face recognition. For voice recognition, three categories of features (statistical coefficients, cepstral coefficients and voice timbre) are used and compared. The voice identification modality is carried out using Gaussian Mixture Model (GMM). For face recognition, three recognition methods (Eigenface, Linear Discriminate Analysis (LDA), and Gabor filter) are used and compared. The combination of voice and face biometrics systems into a single multimodal biometrics system is performed using features fusion and scores fusion. This study shows that the best results are obtained using all the features (cepstral coefficients, statistical coefficients and voice timbre features) for voice recognition, LDA face recognition method and scores fusion for the multimodal biometrics system

Voice-activated intelligent radiologic image display

Fisher, P.

1989-01-01

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

Mkimbili, Selina Thomas; Ødegaard, Marianne

2017-12-01

Fostering and maintaining students' interest in science is an important aspect of improving science learning. The focus of this paper is to listen to and reflect on students' voices regarding the sources of motivation for science subjects among students in community secondary schools with contextual challenges in Tanzania. We conducted a group-interview study of 46 Form 3 and Form 4 Tanzanian secondary school students. The study findings reveal that the major contextual challenges to student motivation for science in the studied schools are limited resources and students' insufficient competence in the language of instruction. Our results also reveal ways to enhance student motivation for science in schools with contextual challenges; these techniques include the use of questioning techniques and discourse, students' investigations and practical work using locally available materials, study tours, more integration of classroom science into students' daily lives and the use of real-life examples in science teaching. Also we noted that students' contemporary life, culture and familiar language can be utilised as a useful resource in facilitating meaningful learning in science in the school. Students suggested that, to make science interesting to a majority of students in a Tanzanian context, science education needs to be inclusive of students' experiences, culture and contemporary daily lives. Also, science teaching and learning in the classroom need to involve learners' voices.

The purpose of this study was to evaluate vocal tract function and the voice quality in singers with muscle tension dysphonia (MTD) after undergoing combined functional voice therapy of the singing voice. This is a prospective, randomized study. Forty singers (29 females and 11 males, mean age: 24.6 ± 8.8 years) with MTD were enrolled in the study. The study group consisted of 20 singers who underwent combined functional voice therapy (10-15 individual sessions, 30-40 minutes each). Singers who did not opt for vocal rehabilitation consisted of the control group. Effects of rehabilitation were assessed with videolaryngostroboscopy, palpation of the vocal tract structures, flexible fiberoptic evaluation of the pharynx and the larynx, perceptual speaking and singing voice assessment, acoustic analysis, maximal phonation time, and the Voice Handicap Index. After combined functional voice therapy in the study group, great improvement was noticed in palpation of the vocal tract structures (P singing range obtained from acoustic analysis of glissando (P singing. Development of palpation and perceptual singing voice examination protocols enables one to compare results before and after rehabilitation in clinics. Copyright © 2017 The Voice Foundation.

Using Hierarchical Time Series Clustering Algorithm and Wavelet Classifier for Biometric Voice Classification

Directory of Open Access Journals (Sweden)

Simon Fong

2012-01-01

Full Text Available Voice biometrics has a long history in biosecurity applications such as verification and identification based on characteristics of the human voice. The other application called voice classification which has its important role in grouping unlabelled voice samples, however, has not been widely studied in research. Lately voice classification is found useful in phone monitoring, classifying speakers’ gender, ethnicity and emotion states, and so forth. In this paper, a collection of computational algorithms are proposed to support voice classification; the algorithms are a combination of hierarchical clustering, dynamic time wrap transform, discrete wavelet transform, and decision tree. The proposed algorithms are relatively more transparent and interpretable than the existing ones, though many techniques such as Artificial Neural Networks, Support Vector Machine, and Hidden Markov Model (which inherently function like a black box have been applied for voice verification and voice identification. Two datasets, one that is generated synthetically and the other one empirically collected from past voice recognition experiment, are used to verify and demonstrate the effectiveness of our proposed voice classification algorithm.

Narrating Identity: the Employment of Mythological and Literary Narratives in Identity Formation Among the Hijras of India

Directory of Open Access Journals (Sweden)

Jennifer Ung Loh

2014-06-01

Full Text Available This article explores how the hijras and kinnars of India use mythological narratives in identity-formation. In contemporary India, the hijras are a minority group who are ostracised from mainstream society as a result of their non-heteronormative gender performances and anatomical presentations. Hijras suffer discrimination and marginalisation in their daily lives, forming their own social groups outside of natal families and kinship structures. Mythological and literary narratives play a significant role in explaining and legitimising behavioural patterns, ritual practices, and anatomical forms that are specific to hijras, and alleviating some of the stigma surrounding this identity. In this article, I focus on certain narratives that hijras employ in making sense of and giving meaning to their lives, including mythological stories concerning people of ambiguous gender and myths associated with Bahuchara Mata. I argue that these ontological narratives serve to bring hijra identity into being and play a crucial role in constructing and authenticating hijra identity in modern India.

Engagement, bonding, and identity across multiple platforms: Avaaz on Facebook, YouTube, and MySpace

Anastasia Kavada

2012-03-01

Full Text Available This article explores the role of social media platforms in transnational activism by examining the case of Avaaz.org, an international advocacy organization aiming to bring people-powered politics to global decision-making. Focusing on the Avaaz website, its channel on YouTube, its page on Facebook and its profile page on MySpace, the article investigates the affordances of these platforms for identity-building, bonding, and engagement. The empirical data is derived from features analysis of the selected web platforms, as well as textual analysis of the comments posted by users. The findings show that while social media platforms make individual voices more visible, their design helps Avaaz to maintain a coherent collective voice. In terms of bonding, platforms allow individual activists to communicate with the organization and to spread its message to their existing social networks, but opportunities for private interpersonal communication with other Avaaz supporters are limited.

Cantor Cutiva, Lady Catherine; Vogel, Ineke; Burdorf, Alex

2013-01-01

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.
