Mutational falsetto voices: voice therapy.

TLDR

The therapy combined perceptual evaluation, ear training, and a new pitch technique to assess and treat mutational falsetto voices. Seven patients exhibited high pitch and reduced maximum phonation time, yet had normal laryngeal examinations, and most achieved normal voice after five therapy sessions.

Abstract

Seven patients with mutational falsetto voices showed that high pitch is a common sign and symptom. The maximum phonation time of patients was shorter than normal. Most of the otolaryngological examination revealed normal larynx. Perceptual evaluation, ear training practice and establishing a new pitch technique were used for assessment and therapy. The voice of most patients improved greatly and became normal within 5 sessions.
