Abstract
Pre- and postsurgical speech segments spoken by patients with spastic dysphonia were submitted to long-time-average-spectrum (LTAS) analysis, and for perceptual assessment of breathiness and overpressure. Breathy phonation corresponded to a steep fall in the LTAS, while overpressured phonation produced higher spectral levels and a less steep fall. Mixed breathy-overpressured phonation produced a somewhat elevated spectrum. Post-surgical changes in overpressure are demonstrated by spectral shifts. Perceptual scores correlated well with the objective acoustic spectral measures.This publication has 9 references indexed in Scilit:
