Mutational falsetto is the most common mutational voice disorder, found in all ages. Clinicians often miss this diagnosis due to unfamiliarity with the condition. The voice of a person with mutational falsetto is high pitched, weak, thin, breathy, hoarse and monopitched.


This study was carried out to evaluate the efficacy of voice therapy in persons with mutational falsetto.


Eleven male patients with ages between 18 and 26 years (mean age 22.18 years, SD 2.52) diagnosed with mutational falsetto underwent acoustical analysis using Praat Software, perceptual analysis using grade, roughness, breathiness, asthenia and strain (GRBAS) scale and psychosocial analysis using emotional component of voice handicap index (VHI). All the components were analyzed pre- and postvoice therapy.


Improvement in acoustic analysis parameters was statistically significant with p-value less than 0.0001(pretherapy mean of fundamental frequency (F0) was 217.45 with SD 8.68, whereas post-therapy mean of F0 was 127.50 with SD 5.32). Significant improvement in perceptual analysis was seen post-therapy on GRBAS scale. Improvement in psychosocial aspect was also statistically significant with p-value less than 0.0001 (pre-therapy mean 26.18, SD 1.72 post-therapy mean 7, SD 1.15).


Voice therapy plays an important role in lowering F0 and alleviation mental agony of the patients with mutational falsetto.
