Bilingual Perception of Dysarthric Speech.

ABSTRACT:

Purpose

Despite the prevalence of bilingualism, research on the understanding of disordered speech has focused almost exclusively on monolingual populations. Hypothesis-driven studies with dysarthric speech have revealed that greater vocabulary knowledge and working memory support understanding in monolingual listeners. However, whether these explanatory models generalize to bilinguals, who differ in both cognitive and linguistic profiles, is unknown. This study examined whether bilingualism affords a perceptual advantage in understanding dysarthric speech, and whether working memory and vocabulary knowledge contribute to that advantage.
