“…Such findings are similar to those reported by other studies which used the tongue trill performance technique and the resonance tube method (12,(18)(19)(20) . Their results described predominance of positive vocal responses at the 3-and 5-minute runtimes of the vocal exercises, as well as a tendency to vocal strain and fatigue and to deterioration of voice quality after seven minutes.…”

“…Finally, the rest period should consider exercise intensity: the higher the exercise intensity, the longer the rest period needed between training series (26) . Regarding training duration, some studies show that ideal vocal exercise runtime ranges from three to five minutes and that, after seven minutes of performance, voice quality tends to worsen and presence of vocal fatigue is observed (12,(18)(19)(20)(21) . The results of the present survey indicate that the optimal prescription time for the high-pitched blowing vocal exercise in women with dysphonia caused by vocal fold nodules is three minutes, and that worsening of voice quality and perception of vocal discomfort occurs after seven minutes.…”

“…Their results described predominance of positive vocal responses at the 3-and 5-minute runtimes of the vocal exercises, as well as a tendency to vocal strain and fatigue and to deterioration of voice quality after seven minutes. The aforementioned studies described significant changes in some acoustic parameters, such as improved overall severity of dysphonia, roughness, and breathiness (12,(18)(19)(20) . This improvement in vocal quality can be explained by the increased myofunctional and aerodynamic balance of phonation, which probably occurred owing to enhanced glottic coaptation and filter-source interaction.…”

“…Its immediate effects were analyzed in dysphonic and non-dysphonic individuals, with observation of improvement in the auditory-perceptual and acoustic parameters of the voice, laryngeal configuration, and vocal self-assessment (3) . Despite the results of the immediate effects of the SOVTE presented in the literature (2,3,5,6,(9)(10)(11)(12)(13)(14)(15)(16)(17) , there are few studies analyzing the time needed for the performance of vocal techniques and their results in the voice of dysphonic individuals and individuals without vocal complaint (12,(18)(19)(20)(21) . Some studies (12,18,19) sought to investigate the optimal performance time for the tongue trill technique in vocally healthy and dysphonic individuals.…”

“…These studies described improvement in vocal quality, acoustic and spectrographic measurements, and vocal self-assessment after three minutes of exercise (18,19) , as well as predominance of positive vocal responses at the 5-minute exercise runtime (12) . Other studies (20,21) investigated the time of completion for the resonance tube exercise, applied to dysphonic women and children and to women without vocal complaints, and also reported positive vocal changes for the exercise runtime of three minutes.…”

RESUMO Objetivo Analisar o resultado dos tempos um, três, cinco e sete minutos de execução do exercício vocal sopro e som agudo, em mulheres com disfonia por nódulos vocais e em mulheres sem queixa de voz. Método Trata-se de um estudo experimental com amostra de conveniência consecutiva. Participaram 30 mulheres disfônicas, por nódulos em pregas vocais (GE), e 30 mulheres sem queixa vocal (GC). Todas executaram o exercício sopro e som agudo durante um, três, cinco e sete minutos. As vogais sustentadas /a/ e a contagem de um a dez foram registradas antes e após cada tempo de execução do exercício. As gravações foram randomizadas e avaliadas por tarefa de comparação por quatro fonoaudiólogos utilizando os parâmetros grau de desvio vocal, rugosidade, soprosidade, antenia, tensão e instabilidade (GRBASI). Para a análise acústica, foram obtidos os parâmetros de frequência fundamental, jitter, shimmer, o quociente de perturbação de frequência, quociente de perturbação de amplitude e proporção harmônico ruído. Depois de cada momento de realização do exercício vocal, as participantes responderam em uma escala visual analógica de desconforto vocal. Resultados A análise perceptivo-auditiva no GE demonstrou melhora do grau geral da disfonia e da soprosidade após três minutos e piora destes parâmetros auditivos após sete minutos de realização do exercício. Houve autopercepção do desconforto vocal após sete minutos de realização do exercício no GE. Conclusão O tempo ideal de prescrição do exercício vocal sopro e som agudo para o grupo das mulheres disfônicas foi de três minutos. O mesmo grupo, após sete minutos, apresentou piora na qualidade da voz e autorreferiu desconforto.
