Use of Auditory Feedback Amplifier in Women Without Voice Complaints: A Comparison of Acoustic Measures, Self-Rated Vocal Effort, and Voice Intensity.

OBJECTIVE: To compare the immediate effects of using MindVox in women without voice complaints for 1, 3, 5, and 7 minutes of reading tasks, on acoustic measurements of the vocal signal in low, medium, and strong intensity emissions; on self-rated effort vocal, and on the intensity of voice reception and production. METHODS: Participants read one text using MindVox for 1, 3, 5, and 7 minutes. After each time, measures of self-rated vocal effort were collected (BORG CR10-BR Scale), as well as samples of the vowel /e/ at low (>70 dB), moderate (≥70 dB and ≤80 dB), and high intensities (>80 dB). Acoustic measurements (F0, short-term acoustic measurements, and cepstral peak prominence measurements) were also collected before and after the procedure and subsequently analyzed in the CTS 5.0 Vox-Metria Program. Voice reception and production intensities were captured during the reading task using two decibel meters. One decibel meter was installed near the ear (average intensity received by the ear (EAVG)) and the other near the lips (average intensity captured near the lips (LAVG)), and the data were submitted for analysis. RESULTS: The Cepstral Peak Prominence-Smoothed increased in the first minute, the Cepstral Peak Prominence increased in the third minute, and the jitter decreased from the first minute. All these changes were observed at low intensity and were maintained at the other time points. For every 5 dB of amplification (EAVG), there was a 1 dB decrease in voice production (LAVG). CONCLUSION: Using MindVox in women without voice complaints brings positive immediate effects in cepstral measures and jitter at low intensity. There is a connection between the intensity of the voice received by the ear and the intensity of voice production.

ABSTRACT Introduction The auditory perception of voice and its production involve auditory feedback, kinesthetic cues and the feedforward system that produce different effects for the voice. The Lombard, Sidetone and Pitch-Shift-Reflex effects are the most studied. The mapping of scientific experiments on changes in auditory feedback for voice motor control makes it possible to examine the existing literature on the phenomenon and may contribute to voice training or therapies. Purpose To map experiments and research results with manipulation of auditory feedback for voice motor control in adults. Method Scope review following the Checklist Preferred Reporting Items for Systematic reviews and Meta-Analyses extension (PRISMA-ScR) to answer the question: "What are the investigation methods and main research findings on the manipulation of auditory feedback in voice self-monitoring of adults?". The search protocol was based on the Population, Concept, and Context (PCC) mnemonic strategy, in which the population is adult individuals, the concept is the manipulation of auditory feedback and the context is on motor voice control. Articles were searched in the databases: BVS/Virtual Health Library, MEDLINE/Medical Literature Analysis and Retrieval System online, COCHRANE, CINAHL/Cumulative Index to Nursing and Allied Health Literature, SCOPUS and WEB OF SCIENCE. Results 60 articles were found, 19 on the Lombard Effect, 25 on the Pitch-shift-reflex effect, 12 on the Sidetone effect and four on the Sidetone/Lombard effect. The studies are in agreement that the insertion of a noise that masks the auditory feedback causes an increase in the individual's speech intensity and that the amplification of the auditory feedback promotes the reduction of the sound pressure level in the voice production. A reflex response to the change in pitch is observed in the auditory feedback, however, with particular characteristics in each study. Conclusion The material and method of the experiments are different, there are no standardizations in the tasks, the samples are varied and often reduced. The methodological diversity makes it difficult to generalize the results. The main findings of research on auditory feedback on voice motor control confirm that in the suppression of auditory feedback, the individual tends to increase the intensity of the voice. In auditory feedback amplification, the individual decreases the intensity and has greater control over the fundamental frequency, and in frequency manipulations, the individual tends to correct the manipulation. The few studies with dysphonic individuals show that they behave differently from non-dysphonic individuals.

Association Between Vocal Symptoms, Communication, Work Environment, and Sense of Coherence in Hospital Health Professionals.

OBJECTIVE: This study aimed to associate the presence of vocal symptoms with sociodemographic and occupational data, work environment self-perception, oral communication wearing a face mask, and the sense of coherence (SOC). METHOD: This cross-sectional analytical observational study included 66 health professionals from a Brazilian hospital. They answered an online questionnaire on sociodemographic aspects, self-perception of the physical work environment, and oral communication at work. The Voice Symptom Scale (VoiSS) and Sense of Coherence Scale (SOC-13) were also applied. The significance level was set at 5% for the statistical analysis. RESULTS: The self-perception of vocal symptoms was 62%. Professionals who considered the noise in their work environment unsatisfactory had more vocal symptoms (P = 0.005), especially in the limitation (P = 0.013) and physical (P = 0.028) domains of the VoiSS. Professionals with higher self-perceived vocal symptoms also reported incoordination between breathing, speech, and articulation (P = 0.041) and self-perceived difficulty being heard with a protective mask (P = 0.033). Professionals with a higher self-perceived score in the limitation domain of the VoiSS also had a higher self-perceived effort to speak with a mask (P = 0.035) and a higher self-perception that other people find it difficult to hear them with a face mask (P = 0.050). There was a weak negative correlation between VoiSS and SOC (P < 0.05) and between its domains (P < 0.05). CONCLUSION: Self-perception of voice symptoms is high among health professionals in a Brazilian public hospital. The presence of these symptoms is related to the perception of a noisy work environment and communication difficulties due to the use of a face mask. The lower the ability to cope with stressful situations, the larger the presence of voice symptoms among health professionals.

University Professors' Communicative Competence and Its Relationship With Interpersonal Communication and Voice Symptoms.

OBJECTIVE: To analyze the association between communicative competence self-assessment and interpersonal communication self-perception and voice symptoms in university professors. METHOD: Cross-sectional, analytical, observational study in 322 professors, who answered sociodemographic and occupational questions and three self-perception protocols: Self-Assessment of Communication Competence (SACCom), Interpersonal Communication Competence Scale (ICCS), and Voice Symptom Scale (VoiSS). The dependent variable was SACCom's yes/no answers. Univariate and multivariate descriptive and inferential data analyses were performed through logistic regression. RESULTS: Most professors were females (55.3%), worked 40 hours (96.6%), and self-reported voice symptoms (72.7%). The largest portion had been in the career for 11-22 years (38.2%). The final multivariate model demonstrated that better self-assessed communicative competence among professors (SACCom) is related to an absence of voice complaints (odds ratio (OR) = 2.17; 95% confidence interval (CI) 1.29-3.65) and better self-perceived interpersonal communication (ICCS) (OR = 1.05; 95% CI 1.02-1.08). The older the professor (OR = 1.03; 95% CI 1.01-1.06), the better their communicative competence (SACCom). CONCLUSIONS: Study professors' self-assessed communicative competence is predominantly high. Those with a better communicative competence self-assessment are older and vocally healthy and self-perceive greater interpersonal communication skills.

Relationships Between Sense of Coherence, Self-perception of Voice and Work Environment Among Teachers.

OBJECTIVE: to analyze the relationship between sense of coherence and sociodemographic data, remote physical work environment, and self-perception of symptoms, vocal handicap and vocal fatigue in teachers. METHODS: Seventy eight teachers pertaining to the municipal education network of a Brazilian capital city participated in the study, during the period of social isolation by COVID-19. An online questionnaire was applied with sociodemographic and physical remote work environment questions, the Sense of Coherence Scale (SOC-13), the Brazilian Dysphonia Screening Tool (Br-DST), the Vocal Fatigue Index (VFI), and the Vocal Handicap Index (VHI-10). Descriptive analysis, bivariate and multivariate Logistic regression models were performed to check the proportion of teachers with high and low SOC among the different categories of independent variables. Student's t test and Mann Whitney test were used to compare SOC, IDV, and VFI scores between the groups, and Hedge's g test was used to access the effect size. The total scores of SOC, VHI and VFI were correlated using Pearson's Correlation Coefficient. All tests adopted a 5% significance level. RESULTS: Male teachers and those over 45 years old were, respectively, 6.79 (95%CI = 1.16-39.58) and 5.27 (95%CI = 1.40-19.76) times more likely to present a high SOC. The variables associated with a lower chance of presenting high SOC were vocal restriction (OR = 0.21; 95%CI = 0.06-0.79) and voice-related physical discomfort (OR = 0.13; 95%CI = 0.02-0.78). Regarding the remote work environment, in bivariate analysis, teachers who were dissatisfied with air quality (OR = 0.08; 95%CI = 0.01-0.65), temperature (OR = 0.11; 95%CI = 0.01-0.92), and noise (OR = 0.25; 95%CI = 0.61-0.99) were less likely to have high SOC. Higher values of SOC are associated with lower self-perception of vocal fatigue and voice handicap (P < 0,001). CONCLUSION: The way individuals face stressful situations interferes with the self-perception of their voice and their work environment. The relationship between the sense of coherence and voice perception is relevant to favor programs to promote vocal health and stress management in teachers.

The Usability and Acceptability of the mHealth "Health and Voice" for Promoting Teachers' Vocal Health.

OBJECTIVE: To evaluate the usability and acceptability of "Health and Voice" for the promotion of vocal health, and to analyze the same with sociodemographic data, work data, self-knowledge data on vocal care, voice disadvantage, and vocal fatigue symptoms in elementary school teachers. MATERIAL AND METHODS: A cross-sectional observational study, with a sample of 277 elementary school teachers from a Brazilian capital. Teachers were invited to access, interact and evaluate the mHealth: "Health and Voice". The evaluation instruments were the questionnaire with information on socio-demographic and work data, the System Usability Scale (SUS), the questionnaire with questions about acceptability, the Voice Handicap Index Protocol (VHI-10), and the Vocal Fatigue Index Protocol (VFI). Descriptive and association analyses were performed by the Chi-square, Fisher exact, Mann-Whitney, and Wilcoxon tests (P ≤ 0.05) RESULTS: the mean SUS score was 81.9 points; the mean of the acceptability questions was 17.24; the VHI-10 was 6.96 points; the VFI was 21.11 points. Most participants rated the acceptability of mHealth as high. There was an association between acceptability and working in two shifts (P = 0.019); between acceptability and usability (P < 0.001); and between usability and self-perception of knowledge about voice care after using mHealth (P = 0.000). The activity perceived as most important was guidance on voice care. CONCLUSION: "Health and Voice" is a vocal guidance tool for teachers that promotes vocal health. It has high usability and acceptability by elementary school teachers. Self-reported knowledge about vocal care increases after its use and those who evaluate the technology with high acceptability are 3.6 times more likely to also classify it with high usability.

Common Mental Disorders and Self-Perceived Interpersonal Communication and Vocal Symptoms in University Professors.

OBJECTIVE: To determine the prevalence of common mental disorders in university professors and to analyze the same with sociodemographic and occupational data, self-perceived interpersonal communication, and vocal symptoms. METHODS: A Cross-sectional analytical observational quantitative study with 322 university professors. Four assessment instruments: the Sociodemographic and Work Information Questionnaire, the Self-Report Questionnaire, the Brazilian Dysphonia Screening Tool, the Interpersonal Communication Competence Scale, and the Voice Symptom Scale. The study performed descriptive and association analyses. The measure of association was the prevalence ratio, estimated with Poisson regression with robust invariance, considering common mental disorders as a dependent variable. RESULTS: The prevalence of common mental disorders in university professors was 27.6%. There was a significant association between such disorders and self-perceived vocal complaints, the suspicion of dysphonia, and self-perceived difficulties in regards to being heard with a mask (sometimes/always). The higher the score in the self-disclosure domain of the Interpersonal Communication Competence Scale the higher the prevalence of common mental disorders in university professors. CONCLUSION: The prevalence of common mental disorders in university professors is high and influences their self-perception of vocal symptoms and interpersonal relationships. Hence, it reinforces the need for measures to maintain university professors' vocal and mental health.

Sense of Coherence and Coping Strategies in Patients With Dysphonia.

AIM: To analyze sense of coherence (SOC) of dysphonic individuals considering the type and degree of dysphonia, coping strategies, and sociodemographic variables. METHODS: This cross-sectional study was performed with 50 dysphonic individuals under follow-up at a Brazilian Speech-Language Pathology Clinic. They answered a questionnaire with sociodemographic information, the PEED-10 (Brazilian Voice Disability Coping Questionnaire) and the Brazilian version of Sense of Coherence scale. The SOC was categorized as high or low using Cluster analysis. After descriptive analysis, data were analyzed through both the bivariate and multivariate logistic regression model method and the Spearman's correlation test (P< 0.05). RESULTS: Most individuals presented a high SOC (60%). Individuals with mild dysphonia were 7.00 times more likely to present high SOC (95% CI = 1.24-39.38).  Individuals between 45 and 70 years old were 5.03 times more likely to present high SOC (95% CI = 1.25-20.28). In addition, the higher SOC, as well as the scores of manageability domain, the lower the use of strategies focused on emotion. CONCLUSION: Patients with mild dysphonia are more likely to have a high SOC. The same goes for individuals over the fourth decade of life. Also, the greater the SOC, the fewer emotional strategies are used to cope with dysphonia.

Sense of Coherence and the fear of public speaking in university students. / Senso de Coerência e o medo de falar em público em universitários.

PURPOSE: To test the association between the Sense of Coherence (SOC) and the fear of public speaking in university students. METHOD: Cross-sectional study was carried out with a sample of 1124 undergraduate students of a Brazilian public university. An online questionnaire was used divided into three blocks: the first evaluated the sociodemographic data and the somatic symptoms of the fear of public speaking; the second evaluated the SOC, through the SOC-13 questionnaire; and the third was composed by the Scale for Self-Assessment in Public Speaking (SSPS), with questions that point out cognitive aspects of this activity. The students were divided into two groups (high SOC and low SOC) through the Two-step Cluster analysis. Data were analyzed descriptively and by the Mann-Whitney test and bi and multivariate logistic regression models, with significance set at 5%. RESULTS: The students who reported not being afraid to speak in public were more likely to belong to the high SOC group (OR = 3.19, 95% CI = 2.30-4.42). Students from the high SOC group self-assessed more positively on the SSPS scale (p <0.001). CONCLUSION: College students over 30 years old, on the second half of graduation, with breathing discomfort, who do not report fear of public speaking and who perceive themselves more positively for public speaking, they have the highest SOC. Thus, it is observed the importance of considering the SOC as an important coping resource, given the great interference of emotional aspects in public speech.

OBJETIVO: Testar a associação entre o Senso de Coerência (SOC) e o medo de falar em público em universitários. MÉTODO: Estudo transversal, com amostra de 1.124 estudantes de cursos de graduação de uma universidade pública brasileira. Foi utilizado questionário online dividido em três blocos: o primeiro avaliou os dados sociodemográficos e os sintomas somáticos do medo de falar em público; o segundo avaliou o SOC, por meio do questionário SOC-13; e o terceiro foi composto pela Escala para Autoavaliação ao Falar em Público (SSPS), que norteia aspectos cognitivos dessa atividade. Os universitários foram divididos em dois grupos (SOC alto e SOC baixo) por meio da análise de Cluster de dois passos. Os dados foram analisados de forma descritiva e por meio do teste de Mann-Whitney e modelos de regressão logística bi e multivariado, com significância de 5%. RESULTADOS: Os universitários que relataram não ter medo de falar em público apresentaram mais chance de pertencer ao grupo SOC alto (OR=3,19, IC95%=2,30-4,42). Os universitários do grupo SOC alto se autoavaliaram mais positivamente na escala SSPS (p<0.001). CONCLUSÃO: Universitários com mais de 30 anos, na segunda metade da graduação, das áreas da Saúde e Exatas, com sintoma de respiração ofegante, que não relatam medo de falar em público e que se autopercebem mais positivamente para falar em público, apresentam o SOC mais alto. Diante do estudo, observa-se a importância de se considerar o SOC como um recurso de enfrentamento importante, tendo em vista a grande interferência dos aspectos emocionais na fala em público.

Self-perception of shyness and its relation to aspects of public speaking. / Autopercepção de timidez e sua relação com aspectos da fala em público.

PURPOSE: To determine the prevalence of shyness in university students and to analyze among the sociodemographic and public communication factors, those that are most related to their presence. METHOD: A cross-sectional analytical study was carried out with 1124 university students aged between 17 and 63 years old. It was used a questionnaire with questions related to sociodemographic characteristics; frequency of participation in public speaking activities; self-report of fear of speaking; self-perception of non-verbal aspects of oral communication: tone of voice, speed of speech, voice intensity, vocal projection, eye contact with the audience during the speech, use hands in public presentations; self-assessment of public speaking (Scale for Self-Assessment in Public Speaking) and self-perception of shyness (Revised Shyness Scale). The analysis of factors associated with shyness and with the other variables was performed by Pearson's chi-square test and univariate and multivariate logistic regression. The level of significance adopted was 5%. RESULTS: The majority of the university population self-reported traces of shyness and fear of speaking in public. There was an association of shyness with the age of 17 to 30 years, fear of speaking in public, little participation in public speaking activities, negative self-perception of speech and with non-verbal communication aspects. CONCLUSION: Shyness is prevalent in young university students, who participate in few public speaking activities, who are afraid to speak in public, self-report speaking at low intensity and who are unable to use their hands naturally during public presentations.

OBJETIVO: Determinar a prevalência da timidez em estudantes universitários e analisar dentre os fatores sociodemográficos e da comunicação em público, aqueles que mais se relacionam com sua presença. MÉTODO: estudo transversal analítico realizado com 1124 universitários com idade entre 17 e 63 anos. Utilizou-se um questionário com perguntas referentes às características sociodemográficas; frequência de participação em atividades de fala em público, autorrelato do medo de falar, autopercepção dos aspectos não verbais da comunicação oral: tom de voz, velocidade de fala, intensidade de voz, projeção vocal, contato visual com a plateia durante o discurso, uso das mãos nas apresentações em público; autoavaliação da fala em público (Escala para Auto Avaliação ao Falar em Público) e autopercepção da timidez (Escala Revisada de Timidez). A análise dos fatores associados à timidez com as demais variáveis foi realizada por meio do teste Qui-quadrado de Pearson e regressão logística uni e multivariada. O nível de significância adotado foi de 5%. RESULTADOS: a maioria da população universitária autorreferiu traços de timidez e medo de falar em público. Houve associação da timidez com a idade de 17 a 30 anos, medo de falar em público, pouca participação em atividades de fala em público, autopercepção negativa da fala e com aspectos não verbais da comunicação. CONCLUSÃO: A timidez é prevalente em estudantes universitários jovens, que participam de poucas atividades de fala em público, que apresentam medo de falar em público, autorrelatam falar em intensidade baixa e apresentam inabilidade de usar as mãos com naturalidade durante apresentações em público.

Self-referred personal behavior profile of university professors: association with communicative and vocal self-evaluation. / Perfil de comportamento pessoal autorreferido por professores universitários: associação com a autoavaliação comunicativa e vocal.

PURPOSE: Describe the self-referred personal behavior profiles of university professors and verify the association of these profiles with the self-assessment of communicative aspects and vocal symptoms. METHODS: Study conducted with 334 professors at a public university who responded to an online questionnaire regarding voice use in teaching practice. Personal behavior profile classification was the response variable, which was divided into four types: pragmatic, analytical, expressive and affable. Explanatory variables were vocal self-perception, vocal resources, and communicative aspects. Descriptive data analysis was performed with application of the Pearson's Chi-squared and Fisher's Exact tests. RESULTS: University professors identified themselves more with the affable and expressive personal behavior profiles. Overall, professors presented good self-perception about vocal and communicative aspects, in addition to having reported few vocal symptoms. Profiles differed for some of the assessed variables, namely, pragmatic professors reported high speech velocity and sporadic eye contact; expressive professors demonstrated self-perception about their voice and strong voice intensity; those in the analytical profile self-reported negative perception about vocal quality, weak voice intensity, poor articulation and rapid speaking rate; the other professors mostly reported voice tiredness symptoms and difficulty projecting the voice. CONCLUSION: University professors identify themselves mostly with the affable and expressive profiles. Self-perception analysis of the personal behavior profile in university professors showed the influence of self-reported personality characteristics on communicative skills in the classroom.

OBJETIVO: Descrever o perfil de comportamento pessoal autorreferido por professores universitários, e verificar a associação destes perfis com a autoavaliação dos aspectos comunicativos e sintomas vocais. MÉTODO: Estudo realizado com 334 professores de uma universidade pública que responderam um questionário online referente ao uso da voz na docência. A variável resposta foi a classificação do perfil de comportamento pessoal, identificado em quatro tipos: pragmático, analítico, expressivo e afável, e as variáveis explicativas foram: autopercepção vocal, recursos vocais e aspectos comunicativos. Foi realizada a análise descritiva dos dados, além dos testes Quiquadrado de Pearson e Exato de Fisher. RESULTADOS: Os professores universitários se identificaram mais com os perfis de comportamento pessoal afável e expressivo. De forma geral, os docentes demonstraram boa autopercepção dos aspectos vocais e comunicativos, além de terem relatado poucos sintomas vocais. Os perfis se diferenciaram em algumas variáveis estudadas: o pragmático relatou velocidade de fala rápida e, às vezes, realizar contato de olhos; o expressivo demonstrou autopercepção positiva de sua voz e intensidade forte. Professores com perfil analítico autorreferiram percepção negativa da qualidade vocal, intensidade fraca, articulação ruim e velocidade de fala rápida e, entre os demais perfis, foi o que mais relatou sintomas de cansaço na voz e dificuldade para projetar a voz. CONCLUSÃO: Professores universitários se identificam predominantemente com os perfis afável e expressivo. A análise da autopercepção do perfil de comportamento pessoal em professores universitários mostra a influência das características da personalidade autorreferidas sobre as habilidades comunicativas em sala de aula.

Vocal Symptoms in University Professors: Their Association With Vocal Resources and With Work Environment.

AIM: Investigating the association among vocal symptoms, vocal resources, and work environment in university professors. METHODS: Online questionnaire answered by 334 professors from a federal public university in Belo Horizonte County, Brazil. The questionnaire addressed sociodemographic data, self-perception about one's voice, vocal resources and work environment, and included the Vocal Signs and Symptoms Questionnaire. Professors presenting five or more vocal symptoms were compared to those who reported fewer symptoms. The association between the number of symptoms and the other variables was assessed through univariate and multivariate logistic regression analyses. RESULTS: The mean of symptoms reported by the herein investigated professors was 3.1 (SD ± 2.75); 24% (n = 82) of them reported five or more vocal symptoms. Factors such as female sex, incidence of noise, high speaking rate, as well as high fundamental frequency and loud voice, were associated with the incidence of five or more vocal symptoms. CONCLUSIONS: University professors belonging to the female sex, who perceive the noise in the work environment as unsatisfactory, speak fast, or present high fundamental frequency and loud voice reported the largest number of vocal symptoms. It is recommended developing education programs focused on raising professors' awareness about voice-related risk factors and about the importance of improving their communicative performance.

ABSTRACT Purpose: To test the association between the Sense of Coherence (SOC) and the fear of public speaking in university students. Method: Cross-sectional study was carried out with a sample of 1124 undergraduate students of a Brazilian public university. An online questionnaire was used divided into three blocks: the first evaluated the sociodemographic data and the somatic symptoms of the fear of public speaking; the second evaluated the SOC, through the SOC-13 questionnaire; and the third was composed by the Scale for Self-Assessment in Public Speaking (SSPS), with questions that point out cognitive aspects of this activity. The students were divided into two groups (high SOC and low SOC) through the Two-step Cluster analysis. Data were analyzed descriptively and by the Mann-Whitney test and bi and multivariate logistic regression models, with significance set at 5%. Results: The students who reported not being afraid to speak in public were more likely to belong to the high SOC group (OR = 3.19, 95% CI = 2.30-4.42). Students from the high SOC group self-assessed more positively on the SSPS scale (p <0.001). Conclusion: College students over 30 years old, on the second half of graduation, with breathing discomfort, who do not report fear of public speaking and who perceive themselves more positively for public speaking, they have the highest SOC. Thus, it is observed the importance of considering the SOC as an important coping resource, given the great interference of emotional aspects in public speech.

Prevalence and factors associated with fear of public speaking. / Prevalência e fatores associados ao medo de falar público.

PURPOSE: To identify the prevalence of fear of public speaking and verify its association with sociodemographic variables, self-perception of voice, speech, and oral communication skills in public. METHODS: A cross-sectional and analytical study with 1,124 university students was carried out. An online questionnaire addressed was performed, considering factors as sociodemographic characteristics; fear of speaking; Scale for Self-Assessment When Speaking in Public (SSPS), self-perception of the voice, the ability to grasp, and keep the listener's attention and influence another. RESULTS: The fear of public speaking was prevalent in undergraduate students. There was an association of the fear of speaking with the vocal self-perception, with the ability to capture and keep the listener's attention and to influence another with their communication. Individuals who have the ability to capture and maintain the attention of the interlocutor are more likely to be afraid of public speaking than the undergraduate students who perceive themselves as having the ability to influence the listener with their communication. CONCLUSION: The more communicative skills and more persuasive the individual perceives his or her self, the less likely he or she is to be affected by the fear of speaking.

OBJETIVO: identificar a prevalência do medo de falar em público e verificar sua associação com as variáveis sociodemográficas, autopercepção da voz, fala e habilidades de comunicação oral em público. MÉTODO: estudo transversal analítico com 1124 universitários. Um questionário online abordou características sociodemográficas, medo de falar, autoavaliação da fala em público por meio da Escala para Autoavaliação ao Falar em Público (SSPS), autopercepção da voz, da capacidade de captar e manter a atenção do ouvinte e de influenciar o outro. RESULTADOS: o medo de falar em público foi muito prevalente nos universitários. Houve associação do medo de falar com a autopercepção vocal, com a capacidade de captar e manter a atenção do ouvinte e influenciar o outro com a sua comunicação. Indivíduos que autorrelataram capacidade de captar e manter a atenção do interlocutor apresentaram maior chance de manifestar medo de falar em público em relação aos universitários que se autoperceberam como capazes de influenciar o ouvinte com a sua comunicação. CONCLUSÃO: quanto mais habilidades comunicativas e mais persuasivo o indivíduo se percebe, menores as chances de ele ser acometido pelo medo de falar em público.
