Dysarthric speech characteristics of Thai stroke patients assessed by the computerized articulation test

Abstract

The dysarthric speech characteristics of 14 Thai stroke patients were assessed by the Computerized Articulation Test [1]. Speech accuracy and error pattern were analyzed. Vowels and tonal characteristics were the most intact characteristics, while reduction of the clusters was the most impaired feature. Both initial and final consonants were frequently substituted, followed by omission and distortion. Generally, low and mid tone, unaspirated consonants and final consonant, monophthong vowels were produced more precisely than the other features.
