Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Observed outcome 1: An improvement in the perception of ease of singing is expected after vocal training with Vocal Function Exercises (VFE) and voiced Oral High-Frequency Oscillation (OHFO), measured using the Evaluation of the Ability to Sing Easily – Brazilian version (EASE-Br) questionnaire | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome 1: both vocal training protocols improved the perceived ease of singing, as evidenced by reduced EASE-Br scores, with no differences between the interventions in this regard;Expected outcome 2: A reduction in vocal fatigue symptoms is expected, measured before and after the interventions using the Vocal Fatigue Index (VFI) questionnaire;Outcome 2 found: No significant difference was observed after either training protocol, with no differences between the groups;Expected outcome 3: An improvement in the perception of vocal comfort during speaking and vocal quality after both training protocols is expected, assessed using a protocol developed by the researchers with a 10-point Likert scale, based on the questions: “How easy is it to produce your voice now?” and “How clear is your voice now?;Found outcome 3: an increase in self-perceived vocal quality was observed after both interventions. However, there was a trend toward improvement in phonatory comfort over time, regardless of the type of intervention;EExpected outcome 4: An improvement in vocal quality is expected, characterized by an increase in the acoustic parameters fundamental frequency (Fo) and Smoothed Cepstral Peak Prominence (CPPS), and a decrease in the multiparametric indices Acoustic Voice Quality Index (AVQI) and Acoustic Breathiness Index (ABI), extracted using the VOXPLOT acoustic analysis software;Found outcome 4: a decrease in the multiparametric indices acoustic index quality (AVQI) and acoustic breathiness index (ABI) was observed only after vocal training with HFOO | — |
