Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Self-assessment of Resonance and Projection quantitatively and qualitatively; Brazilian version of the Evaluation of Ability to Sing Easily scale EASE-BR, a specific protocol for assessing the voice after a singing task, composed of 22 questions about the singing voice, with the possibility of recording the frequency of occurrence (0 = no, 1 = a little, 2 = moderately, and 3 = very much);Auditory-perceptual assessment of speaking and singing voices. The pre and post moments will be randomly arranged for evaluating judges and only the researchers will have access to this information. Three speech therapists specializing in voice and three singing teachers, with a minimum of five years' experience each, will listen and evaluate, through a comparison task, which of the two emissions is worse, shows no changes or better, considering vocal quality. To determine intra-rater agreement, 20% of the sample will be randomly replicated. The Question Pro Forms platform will be used to organize and obtain responses from the judging speech therapists;Acoustic Measures — fundamental frequency, jitter percent, pitch perturbation quotient percent, shimmer percent, amplitude perturbation quotient percent and noise-harmonic ratio and cepstral measures — Cepstral Peak Prominence and the Smoothed Cepstral Peak Prominence | — |
