Abstract

Stress marking strategies employed by subjects with apraxia of speech were compared to those of matched normal controis, for real disyllabic words produced in isolation and in sentences, across acoustic variables of fundamental frequency, syllabie duration and vocal intensity. Heterogeneity of stress marking, in terms of acoustic trading relationships, was observed in both the apraxic and normal subjects: Strategies varied depending upon whether words were produced in isolation or in sentences, and whether the first or second syllable was stressed. Allowing for durational increases in apraxia, there was a negligibie difference between groups. Apraxic subjects tended to exaggerate the strategy employed.
