Summary
Group vocal training improved singers' self-perceived voice quality. While objective measures like phonation time and s/z ratio showed no significant group differences, singers in the intervention group reported fewer voice complaints post-training.
Area of Science:
- Vocal Pedagogy
- Performing Arts Medicine
- Speech-Language Pathology
Background:
- Popular singers often face vocal demands that can impact voice quality.
- Understanding the efficacy of targeted vocal training for this population is crucial.
- This study addresses the need for evidence-based vocal improvement strategies for professional singers.
Purpose of the Study:
- To evaluate the benefits of a group vocal improvement program for popular singers.
- To assess the impact of vocal training on subjective and objective voice parameters.
- To determine if vocal hygiene behaviors change post-intervention.
Main Methods:
- A quasi-experimental study involving 37 popular singers (18-40 years) with adapted vocal quality.
- Participants were assigned to an Intervention Group (IG) receiving vocal training or a Control Group (CG).
- Pre- and post-intervention assessments included questionnaires and objective voice evaluations (resonance, articulation, projection, pitch, loudness, maximum phonation time, s/z ratio).
Main Results:
- Singers in the intervention group perceived significant improvements in their voice production.
- No statistically significant differences were found between groups for maximum phonation time or s/z ratio.
- While not significant, the intervention group showed a higher percentage decrease in voice complaints compared to the control group.
Conclusions:
- Group vocal training positively impacts singers' self-perception of voice production, even with pre-existing adapted voices.
- The intervention may offer subjective benefits in voice quality perception for popular singers.
- Further research could explore longer-term effects and objective vocal parameter changes.
