Results The time duration of voice therapy ranged from 1 to 10 months (average-3.6 months). Pitch and quality of the voice became normal in 78.9% and 35.2% of patients respectively. Pre-therapy perceptual score range(PSR) was 0 to 6 (mean-3.0). Post-therapy PSR was 5 to 10 (mean-7.7). 95.8% patients had improved psychosocial impact and patient satisfaction after voice therapy.
