Design outcomes

Primary

MeasureTime frame
Improved singing voice quality standard demonstrated by the perceptual analysis of voice with CAPE- V, in which there is a decrease in score value pre and post intervention.

Secondary

MeasureTime frame
Improvement of acoustic parameters (mean fundamental frequency, jitter, shimmer, GNE), demonstrated by VoxMetria software. Improved profile vocal range, shown by Vocalgrama software. Improvement of maximum phonation time, demonstrated by measuring the maximum times of sustaining vowels and phonemes /s/ and /z/.
