Acoustic analysis of functional dysphonia: before and after voice therapy (accent method)

J Voice. 1994 Jun;8(2):163-7. doi: 10.1016/s0892-1997(05)80308-x.

Abstract

Ten patients who were referred to a speech pathologist for functional voice disorders were treated with voice therapy using the accent method. The vocal folds were normal except in three females who had moderate bilateral nodules. The voices were analyzed acoustically before and after treatment. Of the parameters tested, pitch perturbation quotient, amplitude perturbation quotient, normalized noise energy for 1-4 kHz, and fundamental frequency showed significant improvement.
