Características vocais acústicas do som basal em homens com fissura pós-forame reparada

Abstract: RESUMOTema: características vocais acústicas da emissão em registro basal de pacientes adultos masculinos, portadores de fissura palatina pós-forame reparada cirurgicamente. Procedimentos: estudo de casos envolvendo quatro sujeitos do sexo masculino portadores de fissura palatina pós-forame reparada cirurgicamente. Foi realizada análise acústica da emissão sustentada da vogal [a] em registro modal e basal, através dos programas Multi Dimensional Voice Program (análise da fonte glótica) e Real-Time Spectrogram … Show more

“…The levels of frequency disturbance (jitter) during the BR emissions are also significantly higher than those observed in the modal register, both in normal and in pathological voices, the same happened with the measures of intensity of disturbance (shimmer) and with the presence of noise (1,18,19,(32)(33)(34)(35) .…”

“…The vocal processes of the arytenoids appear to be leveraged anterior and medially and may further reduce the posterior glottic gap (18) . The thickening of the vocal folds, together with the decreased stiffness of the vocal ligament during the BR may be the main contributing factors to reduce the speed of vocal fold vibration by altering the characteristics of the vibratory cycle, in which the vocal folds open and close from one to three times in rapid succession (depending on the author) and after that, they come to a closed position for a longer period of time, in a vibration pattern of pulses that also characterizes this register (1,3,4,6,7,9,18,19,21,28,(30)(31)(32)(33)(34)(35)(36) .…”
