Articulatory-to-Acoustic Relations in Talkers With Dysarthria: A First Analysis

Abstract

The findings on interspeaker articulatory-to-acoustic relations suggested that the degree of tongue displacement can be accurately inferred from the degree of acoustic vowel contrast in talkers with PD but not in talkers with ALS. Findings on intraspeaker articulatory-to-acoustic relations generally supported the longstanding notion that speaking rate-induced changes in tongue displacement evoke similar changes in acoustic vowel contrast. Differential effects of the pathophysiology on inter- and intraspeaker articulatory-to-acoustic relations are discussed.
