Summary
Voice therapy effectively treats mutational falsetto, normalizing vocal pitch and quality. Objective and perceptual analyses confirm sustained improvements six months post-intervention.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Background:
- Mutational falsetto, a persistent high-pitched voice in males post-puberty, impacts communication.
- Therapeutic intervention is the primary treatment modality for mutational falsetto.
Purpose of the Study:
- To assess the efficacy of voice therapy for mutational falsetto.
- To evaluate changes in acoustic and perceptual voice parameters post-intervention.
Main Methods:
- Retrospective study of 45 patients with mutational falsetto undergoing voice therapy.
- Acoustic analysis included fundamental frequency, jitter, shimmer, and formants (1, 2, 3) using the Multi-Dimensional Voice Program.
- Perceptual voice analysis used a graded severity-roughness-breathiness-aesthenicity-strain scale.
Main Results:
- Significant reductions in fundamental frequency, jitter, shimmer, and formants 1 & 2 post-therapy.
- Perceptual evaluation indicated a shift from falsetto to chest voice in all patients.
- Sustained improvements were observed at 3- and 6-month follow-ups.
Conclusions:
- Voice therapy is effective in normalizing the speaking fundamental frequency in mutational falsetto.
- Objective and perceptual voice measures confirm successful treatment outcomes.
- Normal voice quality can be maintained long-term after intervention.
