Brief summary
This research aims to evaluate the effects of vocal conditioning through two semioccluded vocal tract exercises (SOVTE) in choir singers.
Detailed description
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.
Interventions
OTHERFinnish tube
Practice the exercise with Finnish tube before choir practice once a week for a period of 14 weeks.
OTHERStaw phonation
Practice the exercise straw phonation before choir practice once a week for a period of 14 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Voice quality | 3 months | 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
| Measure | Time frame | Description |
|---|---|---|
| Jitter | 3 months | Improvement of acoustic parameters, demonstrated by VoxMetria software. |
| Shimmer | 3 months | Improvement of acoustic parameters, demonstrated by VoxMetria software. |
| Mean fundamental frequency | 3 months | Improvement of acoustic parameters, demonstrated by VoxMetria software. |
| Profile vocal range | 3 months | Improved profile vocal range, shown by Vocalgrama software. |
| Maximun phonation time | 3 months | Improvement of maximum phonation time, demonstrated by measuring the maximum times of sustaining vowels and phonemes /s/ and /z/. |
| Glottal to Noise Excitation (GNE) | 3 months | Improvement of acoustic parameters, demonstrated by VoxMetria software. |
