Abstract

<p>We developed a shortened version of Vocal Function Exercises (VFE) which consists only of vocal continuous practice at specific heights and vocal continuous practice, and we examined its efficacy in healthy people. A total of 29 normal female adults were divided into 3 groups: continuous vocalization group, chest voice group, and falsetto group; and voice training was undertaken for 10 days. Before and after the training, we examined maximum phonation time (MPT), aerodynamics, physiological voice range, acoustics and subjective evaluation. The results showed that in the chest voice group, extension of MPT, expansion of physiological voice range, and decrease of amplitude perturbation quotient (APQ) were recognized to a significant degree. From this study we concluded that our newly devised shortened version of VFE could enable a shorter training period and shows promising efficacy as a modality of voice therapy.</p>
