About this study
This research aims to evaluate the effects of vocal conditioning through two semioccluded vocal tract exercises (SOVTE) in choir singers.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Finnish tubeOther
Practice the exercise with Finnish tube before choir practice once a week for a period of 14 weeks.
Staw phonationOther
Practice the exercise straw phonation before choir practice once a week for a period of 14 weeks.
| Study group | Role | What they receive |
|---|---|---|
| Group 1 | Experimental | 20 individuals of Coral UFCSPA without voice problems carry out the exercise with Finnish tube before choir practice once a week for a period of 14 weeks. The exercise will be carried out with blowing set to sound at regular frequency, with frequency variation and with the melody of "Happy Birthday"; each sequence will be held for 2 minutes with 1 minute interval between them. Receives: Other: Finnish tube |
| Group 2 | Experimental | 20 individuals of Coral UFCSPA without voice problems carry out the exercise straw phonation before choir practice once a week for a period of 14 weeks. The exercise will be carried out with blowing set to sound at regular frequency, with frequency variation and with the melody of "Happy Birthday"; each sequence will be held for 2 minutes with 1 minute interval between them. Receives: Other: Staw phonation |
| Group 3 | No intervention | 10 individuals of Coral UFCSPA without voice problems. Untreated group. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Voice quality
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.
Measured: 3 months
Secondary outcomes (6)
Mean fundamental frequency
Improvement of acoustic parameters, demonstrated by VoxMetria software.
Measured: 3 months
Jitter
Improvement of acoustic parameters, demonstrated by VoxMetria software.
Measured: 3 months
Shimmer
Improvement of acoustic parameters, demonstrated by VoxMetria software.
Measured: 3 months
Glottal to Noise Excitation (GNE)
Improvement of acoustic parameters, demonstrated by VoxMetria software.
Measured: 3 months
Profile vocal range
Improved profile vocal range, shown by Vocalgrama software.
Measured: 3 months
Maximun phonation time
Improvement of maximum phonation time, demonstrated by measuring the maximum times of sustaining vowels and phonemes /s/ and /z/.
Measured: 3 months

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Voice quality (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2017; AzTrials last refreshed its copy on 7 Nov 2026.
