AbstractThe human voice is not only the key to human communication but also serves as the primary musical instrument. Many professions rely on the voice, but the most noticeable and visible are singers. Care of the performing voice requires a thorough understanding of the interaction between the anatomy and physiology of voice production, along with an awareness of the interrelationships between vocalisation, acoustic science and non-vocal components of performance. This review gives an overview of the care and prevention of professional voice disorders by describing the unique and integrated anatomy and physiology of singing, the roles of development and training, and the importance of the voice care team.

Purpose: To determine the main voice disorders of humanitarian departments’ teachers, their reasons and effective methods to keep the voice in a health condition. Material: In the research participated 142 teachers of H. S. Skovoroda Kharkiv National Pedagogical University and National Aerospace University – "Kharkiv Aviation Institute" (n=106 women, n=36 men). The study involved auditory assessment of teachers' voice and questionnaire in order to determine teachers’ professional voice problems and factors influenced on the status and quality of the voice. Results: It was determine the maximum phonation time for participants of genders, the voice disorders frequency, typical problems with teachers' voice, the positive and negative factors affecting the voice system condition. Also participants answered the questionnaire’s questions about voice using. Conclusions: the study showed that teachers take their voice for granted and do not always care about it; use their voice in an unhealthy condition and they are not always aware of the negative consequences for their health.

Nonlinear measures such as the correlation dimension, the correlation entropy, and the noise level were used in this article to characterize normal and pathological voices. These invariants were estimated through an automated algorithm based on the recently proposed U-correlation integral. Our results show that the voice dynamics have a low dimension. The value of correlation dimension is greater for pathological voices than for normal ones. Furthermore, its value also increases along with the type of the voice. The low correlation entropy values obtained for normal and pathological type 1 and type 2 voices suggest that their dynamics are nearly periodic. Regarding the noise level, in the context of voice signals, it can be interpreted as the power of an additive stochastic perturbation intrinsic to the voice production system. Our estimations suggest that the noise level is greater for pathological voices than for normal ones. Moreover, it increases along with the type of voice, being the highest for type 4 voices. From these results, we can conclude that the voice production dynamical system is more complex in the presence of a pathology. In addition, the presence of the inherent stochastic perturbation strengthens along with the voice type. Finally, based on our results, we propose that the noise level can be used to quantitatively differentiate between type 3 and type 4 voices.

AbstractFunctional assessment and therapy methods are necessary for a client-centered approach that addresses the client's vocal needs across all environments. The purpose of this article is to present the approach with the intent to encourage discussion and implementation among educators, clinicians, researchers, and students. The functional approach is defined and its importance is described within the context of the World Health Organization's International Classification of Functioning, Disability, and Health with support provided by synchronous and asynchronous telepractice, the VoiceEvalU8 app, server, and web portal, and a framework that defines voice qualities (e.g., resonance, twang, loud, and others) by the anatomy and physiology of the voice production system (i.e., Estill Figures for Voice). Case scenarios are presented to highlight application of the functional voice approach.

Purpose The human voice is an exceptionally versatile instrument that is capable of complex communicative and emotive behaviors. Typically, these behaviors are sufficient for daily communication activities; however, elite vocal athletes have higher vocal demands and arguably enhanced vocal capabilities. The current definition of a voice disorder is a change in quality, pitch, and loudness of the voice that draws attention to the speaker. In this article, we suggest that this definition does not provide an adequate description of voice problems of elite vocal athletes. Conclusion As a result, the current clinical system of evaluation and intervention may fail to meet the needs of the exceptional voice when even a subtle decline in vocal quality may affect performance. Under the current definition of a voice disorder, these vocal changes may not qualify for vocal rehabilitation supported by 3rd-party payers. To address this issue, we offer a definition of the exceptional voice, propose expansion of the current voice production continuum to include high-level vocal performers, and provide recommendations for the rehabilitation and habilitation of the exceptional voice.

Vocal imitation is a hallmark of human communication that underlies the capacity to learn to speak and sing. Even so, poor vocal imitation abilities are surprisingly common in the general population and even expert vocalists cannot match the precision of a musical instrument. Although humans have evolved a greater degree of control over the laryngeal muscles that govern voice production, this ability may be underdeveloped compared with control over the articulatory muscles, such as the tongue and lips, volitional control of which emerged earlier in primate evolution. Human participants imitated simple melodies by either singing (i.e. producing pitch with the larynx) or whistling (i.e. producing pitch with the lips and tongue). Sung notes were systematically biased towards each individual's habitual pitch, which we hypothesize may act to conserve muscular effort. Furthermore, while participants who sung more precisely also whistled more precisely, sung imitations were less precise than whistled imitations. The laryngeal muscles that control voice production are under less precise control than the oral muscles that are involved in whistling. This imprecision may be due to the relatively recent evolution of volitional laryngeal-motor control in humans, which may be tuned just well enough for the coarse modulation of vocal-pitch in speech.

AbstractIntroductionThe voice represents a basic working tool for carrying out certain occupations. Hoarseness, as a consequence of vocal fold lesions, presents an important cause of work-related absences for voice professionals.MethodsOur study was designed as a retrospective cohort one. Data on gender, workplace, vocal load and exposure to risk factors for voice disorders of the patients who had surgery in the 2014-2015 period at the tertiary centre due to benign vocal fold lesions were collected from their clinical records. We compared professional voice users (PVU) to subjects with no vocal load at work (NPVU). The SPSS programme, version 22.0, was used for statistical analysis.ResultsFrom 2014 to 2015, 103 PVU and 132 NPVU were surgically treated for benign vocal fold lesions. In comparison to the second group, loud speech use was reported significantly more often by PVU (40.8% vs. 14.4%), as was a fast speaking rate (22.3% vs. 9.8%) and additional vocal load outside of the workplace (23.3% vs. 12.9%). The time that had passed between the occurrence of the hoarseness and the surgical treatment did not differ between the groups. The majority of patients were satisfied with the outcome of the operation.ConclusionsNearly a half of the operated patients had a considerable vocal load at work. An ENT assessment prior to starting a job as well as priority phoniatric treatment of voice disorders for PVU would significantly reduce the costs of work absences and contribute to a speedier recovery and return to the workplace.

EMG activity from the inferior constrictor and cricopharyngeus muscles and the voice signal were obtained from 18 laryngectomized male subjects as they produced isolated vowels using alaryngeal phonation. To inflate the esophagus prior to phonation, all subjects but one demonstrated a similar muscle pattern: either one or both muscles studied showed a burst of activity at the moment of inflation. The remaining subject had a muscle pattern during inflation that was identical to a post-laryngectomy swallowing pattern. No typical or modal muscle patterns were found for subjects during the phonatory portion of the alaryngeal voice task. Consistency of pattern within each subject was extremely high during a given procedure and on repeated procedures. The findings suggested that poor talkers had less control of differential muscle contraction than did the adequate talkers and that each laryngectomized talker adopts a phonatory method that is unique to him and consistent with his postoperative anatomy and physiology.

Introduction: Our voice can realize a very importante function in human communication and also is present and helps the various relationships that exist in the different types of jobs and depends on a good voice production to satisfy their work demands. The teacher, among the voice proffessionals, is who presents more occurrence of Voice Disturb (DV). Purpose: To investigate the occurrence of voice symptoms in teachers that Works on Preschool and Elementary school of the public municipality Campinas’ education in the north district, and associate them to voice habits at the work and their life style. Methods: Schools were selected after a statistical calculation to compose a representative sample of the participants and the questionary “Condição de Produção Vocal – Professores (CPV-P)”, compose by 64 questions were answered by the teachers. Results: The collected datas of 63 teachers were organized in Excel worksheet and were analysed in descriptive and inferential statisticts. Through the Chi-square test and the exact test of Fisher were analysed the association between the variables, considering the level of significance of 5%. The presence of DV was considered by the dependent variable, that was detected by the “Índice de Triagem do Distúrbio de Voz – ITDV”, which considers a probable DV, according to the checked option, and showed that 47,6% of the teachers has DV. Conclusion: Almost the most of the teachers has DV in association with others facts that are present at the work and in teachers’ daily voice habits.
