“…In a single-case study, Guzman et al [20] found a decreased CQ compared to the baseline condition. In an investigation to describe changes in aerodynamic and electroglottographic measures, Dargin and Searl [31] found that, in general, EGG CQ tended to increase after practicing. Overall, the studies more clearly support the change in CQ during semi-occluded exercises, but not after practicing.…”

“…Apresentaram-se 58 voluntários para participar da pesquisa, que eram sujeitos sem disfonia, mas com interesse em realizar aperfeiçoamento vocal. Após a aplicação dos critérios acima, 13 foram excluídos pelos seguintes motivos: um por estar em período menstrual; um por ser cantor; dois por serem homens; um por apresentar edema de pregas vocais; um por microweb; um por sulco vocal; um por nódulos vocais; cinco por não terem realizado todas as avaliações necessárias e um por apresenanalisando os efeitos antes e após sua execução [3][4][5] ou comparando os efeitos de diferentes ETVSO 6,7 . A técnica finger kazoo é uma variação de ETVSO em que há a oclusão parcial dos lábios e resistência à saída do som, favorecendo a percepção de todo o trato vocal, otimizando as sensações internas e melhorando a firmeza glótica 8 .…”

“…They aim to promote aerodynamic and vocal tract changes (9,10) and increase the filter-source interaction by increasing supraglottic and intraglottic pressure, consequently favoring impedance through adduction of the vocal fold and narrowing of the epilarynx tube, which result in vocal production with less effort and greater efficiency and economy (7,10) . In the literature, there is evidence that the performance of SOVTEs produces immediate positive effects such as increase in the vocal fold contact quotient (9) , vocal economy, and improvement of the vocal quality (10) , acoustic measures, and vocal self-perception. Such results were obtained in the assessment of individuals without vocal complaints (2,3,6,(11)(12)(13) , the elderly (5,14) , dysphonic individuals (15) , teachers with behavioral dysphonia (16) , and voice professionals (17) .…”

“…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.…”
