The effects of head posturing on the voice and listeners' perception of masculinity

Howerton, Claire Elizabeth 14 May 2024 (has links)
PURPOSE: The purpose of this study was to investigate the impact of head position on unfamiliar listeners’ perception of vocal masculinity. METHOD: Twelve cisgender women were recruited as speaking participants in this study. Participants were recorded reciting two voiced sentences at eight time points with varying head positions including baseline, flexed, and extended. Voice samples were cropped and fundamental frequency (fo) was resynthesized to control for any changes in fo across conditions. Twelve cisgender adults were recruited as listening participants. Listeners were presented with 144 paired comparisons of speaker samples and were prompted to select the sample that sounded more masculine in each presented pairing. Ratings of masculinity were analyzed using Thurstone’s law of comparative judgment. A repeated measures one-way analysis of variance (ANOVA) was used to assess the effect of head positioning and repetition, followed by Dunnett’s post hoc tests for significant factors. RESULTS: The ANOVA showed a statistically significant effect of head position on listener perceptions of masculinity. Dunnett’s post hoc tests revealed a statistically significant effect of the flexed position and no statistically significant effect of the extended compared to the neutral condition. CONCLUSION: Speakers’ voices in the flexed head position were perceived as most masculine by unfamiliar listeners. Overall, the results of this study support the use of head posture manipulation to achieve increased vocal masculinity, which adds to the limited research related to voice masculinization strategies for those seeking gender-affirming voice care.

Constructive Voice Feedback Loops Within and Across Jobs

Schlotzhauer, Ann 01 January 2024 (has links) (PDF)
This dissertation leveraged signaling theory to examine feedback loops in employees' constructive voice behavior. Utilizing an event-focused lens, I examined how past experiences with voice behavior can impact an organizational newcomer's willingness to voice. Given contention in the literature on managerial responses to voice, I distinguished between voice implementation and voice appreciation and developed and validated a measure of voice implementation. Using a vignette design, Study 1 provided experimental evidence that a supervisor's voice implementation and appreciation in response to an organizational newcomer's first voice event in a new job impact the likelihood of that employee voicing again. Also using a vignette design, Study 2 provided experimental evidence that organizational newcomers consider their leader-member exchange quality with their current supervisor as well as voice implementation from their previous supervisor when deciding whether to voice for the first time in a new job. In a three-wave field data collection, Study 3 failed to support the hypotheses. However, novel information was discovered about the prevalence and frequency of constructive voice behavior in organizational newcomers. Theoretical and practical implications are discussed.

Protocolo terapêutico baseado em exercícios de trato vocal semiocluído em indivíduos disfônicos: estudo clínico, randomizado e cego / Therapeutic protocol based on semi-occluded vocal tract exercises in dysphonic subjects: a blind randomized clinical trial

Antonetti, Angélica Emygdio da Silva 25 February 2019 (has links)
Introdução: A terapia vocal indireta pode ser dividida em direta e indireta. A Terapia Vocal Indireta (TVI) é composta por orientações a respeito de higiene vocal e mecanismos fisiológicos da produção da voz, orientando o indivíduo sobre hábitos inadequados para a voz. Já a terapia direta é constituída pela prática de exercícios vocais para aprimorar a qualidade vocal. A terapia direta, pode ser composta por diversos exercícios, dentre as diversas abordagens terapêuticas encontram-se os exercícios de função vocal (EFV), um grupo de exercícios que visa a melhora dos três subsistemas para a produção da voz: respiração, ressonância e fonação. Há ainda outros exercícios de trato vocal semiocluído (ETVSO), em que ocorre a semioclusão do trato vocal, possibilitando interação fonte/filtro por meio de mudanças na impedância do trato vocal. Estudos que comprovem a eficiência dos ETVSO em processo terapêutico são escassos. Acredita-se que uma proposta como essa poderá contribuir para a prática clínica. Proposição: Analisar os efeitos da aplicação de um protocolo de Exercícios de Trato Vocal Semiocluído (ETVSO) na qualidade vocal e autopercepção de indivíduos com queixa de fadiga vocal e diagnóstico de disfonia funcional, e comparar seus efeitos com os EFV e com TVI. Metodologia: Estudo clínico randomizado e cego. Participaram 27 voluntários (12 homens e 15 mulheres), com idades entre 18 e 50 anos, com queixas de fadiga vocal e disfonia funcional, divididos igualmente em três grupos: grupo experimental, com aplicação de ETVSO (GE), grupo de exercícios de função vocal (GEFV) e grupo de terapia indireta (GTVI). Após assinarem o termo de consentimento livre e esclarecido, os voluntários realizaram três avaliações nos seguintes momentos: antes da intervenção (M1), imediatamente após o término da intervenção (M2) e um mês após o término (M3). Foram avaliados o Índice de Fadiga Vocal (IFV), sensação de economia vocal, Índice de Desvantagem Vocal (IDV) e a qualidade vocal (análise perceptivo-auditiva e acústica). Para os três grupos, o protocolo de terapia foi composto por oito sessões, duas vezes/semana com duração de 35 minutos. Aplicou-se o teste ANOVA de medidas repetidas (p<0,05) e Tukey para comparação dos dados antes e após as intervenções e entre grupos. Resultados: Os resultados foram estatisticamente significantes para o fator momento para as seguintes variáveis: IFV (p<0,001), economia vocal (p=0,007), IDV (p<0,001). Para IFV e IDV houve redução dos escores em M2 que mantiveram-se em M3, porém, para economia vocal em M2 há aumento e M3 os valores tendem a aproximar-se de M1. A análise perceptivo-auditiva para Grau Geral e Rugosidade na vogal (p=0,015 e p=0,029) e na contagem (p=0,036 e p=0,039), mostraram que os grupos são diferentes entre si. Por fim, a análise acústica para frequência fundamental (p<0,001) demonstrou que mulheres possuem valores mais elevados que homens e que a Proeminência do Pico Cepstral-suavizada na emissão da vogal (p=0,019) em mulheres é menor que em homens. Conclusão: Em indivíduos com disfonia funcional e queixa de fadiga vocal, os ETVSO são tão efetivos em relação à autopercepção de fadiga vocal, economia vocal e desvantagem vocal quanto aos EFV e TVI. Da mesma forma que os EFV e a TVI, o protocolo de ETVSO apresentara nenhuma mudança na qualidade vocal na população estudada. / Introducion: The voice therapy can be divided into direct and indirect. The indirect vocal therapy (IVT) are vocal hygiene orientations and voice physiologic production orientations, making the subject aware of harmful vocal habits. The direct therapy can be composed by voice exercises, such as Vocal Function Exercises (VFE) that improve the voice production subsystems: breathing, resonance, and phonation. Another way of direct therapy is using the semi-occluded vocal exercises (SOVTE), these exercises enable better filter and source interaction by the means of acoustic impedance changes. Studies that use a SOVTE protocol are almost zero. Therefore it is believed that a SOVTE protocol can contribute to voice clinic. Objective: Verify the effect of the treatment with SOVTE protocol at self-assessment and voice quality in dysphonic subjects. Compare it with VFE and Vocal Hygiene Approach. Methodology: Randomized and blind clinical trial. Twenty-seven volunteers (12 men and 15 women) were included in this study. They aged between 18 to 50 years old, with vocal complaints about vocal fatigue, and they received the functional dysphonia diagnose. The volunteers were equally divided into three groups: Experimental Group (EG), Vocal Function Exercises Group (VFEG), and Indirect Vocal Therapy Group (IVTG). After they filled the consent form, they were assessed by the researcher at three moments: before the intervention (M1), immediately after it (M2), and one month after it (M3). The researcher used the Vocal Fatigue Index (VFI), selfassessment of the vocal economy, Vocal Handicap Index (VHI), perceptual, and acoustic analysis. For the three groups, the interventions happened twice per week (four weeks) and last 35 minutes. It was used Repeated measures ANOVA test (p<0,05) and Tukey Test. Results: There were statistically significant results in the moment factor for IFV (p<0,001), vocal economy (p=0,007), and VHI (p<0,001). In M2 there was a decrease in the IFV and VHI scores keeping to M3. The vocal economy improved in M2, whereas in M3 it decreases, tending to M1 values. Regarding perceptual analysis, for general degree and roughness in the sustained vowel (p=0,015 e p=0,029) and counting numbers (p=0,036 e p=0,039), they only show that the groups are different. In the acoustic parameter of the fundamental frequency (p<0,001), women show greater values than men and the Cepstral Peak Prominence-smoothed (p=0,019) women show a smaller value than men. Conclusion: The subjects with functional dysphonia e vocal fatigue complaints, the SOVTE protocol is effective as VFE and IVT, regarding vocal fatigue, vocal economy, and vocal impairment. All interventions groups did not have changes at voice quality in this population.

Análise nasofibroscópica dos efeitos das técnicas vocais em pacientes com queixa vocal após tireoidectomia / Nasofibroscopic analysis of the effects of vocal techniques in patients with vocal complaint after thyroidectomy

Morone, Wanessa 09 March 2015 (has links)
Introdução: A terapia vocal após tireoidectomia tem como objetivo reduzir características de rugosidade, soprosidade, tensão e incoordenação pneumofonoarticulatória. A nasofibroscopia é um exame que permite analisar alterações orgânicas, neurogênicas e funcionais de laringe, assim como observar o comportamento laríngeo durante a execução de técnicas vocais. Objetivo: analisar a configuração laríngea em pacientes com queixa vocal após tireoidectomia durante a execução das técnicas terapêuticas. Método: Trata-se de um estudo transversal observacional comparativo no qual foram avaliados indivíduos adultos atendidos pelo Serviço de Cirurgia de Cabeça e Pescoço do Hospital das Clínicas da Faculdade de Medicina da USP. A amostra foi composta por 31 indivíduos do gênero feminino, entre 20 e 50 anos, dos quais 21 com queixa vocal após tireoidectomia total ou parcial e dez sem cirurgia ou tratamento prévio de doença de tireoide. A amostra foi dividida em três grupos: com mobilidade laríngea (GEmob, n=16), sem mobilidade laríngea (GEimob, n=5) e o grupo-controle (GC, n=10), todos sem terapia fonoaudiológica prévia. Foram submetidos à nasofibroscopia e instruídos a repetir duas vezes, por cinco segundos, cada uma das seguintes técnicas: vogal /a/ prolongada com mãos em gancho (AMEG), vibratório de língua (VL) e fonação com canudo (FC). As imagens do exame foram analisadas por dois juízes concomitantemente, que preencheram parte do Protocolo de Cooperação Fonoaudiológica para a Avaliação Nasofibrolaringoscópica da Mobilidade Laríngea em Doenças da Tireoide - PAN para observação da configuração laríngea. Resultados: Não houve diferença significante no grupo GEimob. Quando comparados a vogal /a/ com AMEG e FC, houve mudança no movimento ântero-posterior nos grupos GEmob e controle. Conclusão: As técnicas FC e AMEG alteraram a configuração laríngea supraglótica em pacientes com mobilidade laríngea. A técnica AMEG promoveu maior adução de pregas vocais em pacientes com imobilidade / Vocal therapy after thyroidectomy aims to reduce roughness, breathiness, strain and pneumophonoarticulatory incoordination. Nasofibroscopy is a test that permits the analysis of organic, neurogenic and functional larynx alterations, as well as the observation of laryngeal behavior during the execution of vocal techniques. The aim of this study was to analyze laryngeal configuration in patients with vocal complaint after thyroidectomy during the performance of therapeutic techniques. A transversal observational comparative study in which adults were seen by the Hospital das Clínicas Head and Neck Service, São Paulo University Medical School. The sample was composed of 31 people of the female gender, aged between 20 and 50 years old, 21 with vocal complaint after total or partial thyroidectomy, and 10 with no surgery or previous treatment for a thyroid disease. The sample was divided into three groups: with laryngeal mobility (mobSG, n=16), with no laryngeal mobility (immobSG, n=5) and the control group (CG, n=10), all with no previous phonoaudiological therapy. Groups were submitted to nasofibroscopy and instructed to repeat twice, for 5 seconds, each of the following techniques: prolonged /a/ vowel with hooked hands (AMEG), tongue trill (TT) and straw phonation (SP). The images of the test were analyzed by two judges simultaneously, who filled in part of the Phonoaudiological Cooperation Protocol for Nasofibrolaryngoscopic Assessment of laryngeal mobility in Thyroid Diseases - PAN for the observation of laryngeal configuration. There was no significant difference in the immob SG group. When the /a/ vowel was compared with AMEG and SP, there was some change in anteroposterior movement in groups SGmob and control. Conclusion: SP and AMEG techniques alter supraglottic laryngeal configuration in patients with laryngeal mobility. The AMEG technique allows for more adduction of the vocal folds in patients with immobility
