Direct linkLansford, Kaitlin L.; Liss, Julie M. – Journal of Speech, Language, and Hearing Research, 2014
Purpose: The aim of the present report was to explore whether vowel metrics, demonstrated to distinguish dysarthric and healthy speech in a companion article (Lansford & Liss, 2014), are able to predict human perceptual performance.

Peer reviewedAnsel, Beth M.; Kent, Raymond D. – Journal of Speech and Hearing Research, 1992
This study used a contrasting word task to evaluate the relationship between specific acoustic features of speech and perceptual judgments of word intelligibility of 16 adults with cerebral palsy-dysarthria. The scaled intelligibility was predicted with 62.6 percent accuracy by acoustic measures related to one consonant contrast and three vowel…
