简要总结
This research aims to evaluate the effects of vocal conditioning through two semioccluded vocal tract exercises (SOVTE) in choir singers.
详细描述
This research aims to evaluate the effects of vocal conditioning through two semioccluded vocal tract exercises (SOVTE) - Finnish tube and phonation in high strength straw - in vocal parameters, vocal extension profile and maximum phonation time for a period of four months in a group of singers. acoustic analysis will be performed of the average parameters of the fundamental frequency (F0), jitter, shimmer and glottal to Noise Excitation (GNE) by VoxMetria program and perceptual analysis through Consensus Assessment Perceptual Hearing the Voice Protocol (CAPE-V) three times: before the vocal conditioning, after the last meeting of the technical realization and a week after the vocal conditioning period.
