Abstract

This study compared the durations of selected vowels and consonants produced by three groups of aphasics and a normal control group in confrontation naming and single-word repetition tasks. There were seven aphasic subjects in each of the syndromes of Broca's, Wernicke's, amnesic, and conduction aphasia, in addition to a group of seven normal subjects. Wide-band spectrograms were used to measure speech sound durations. Analysis of group data revealed no significant differences in the durations of vowels or consonants across the four subject groups. In addition, there were no differences in speech sound durations for the confrontation naming versus repetition tasks. When two speech-language pathologists listened to tape recordings of all subjects performing the two tasks, they judged the speech of two Broca's aphasics as being labored, while the speech of the remaining subjects was not judged as labored. Clinical judgments of labored speech appeared to correspond to acoustical measurements of speech sound duration, as the two Broca's aphasics judged to be labored displayed longer durations than those subjects who were not judged as labored. The increase in duration was particularly marked for vowels and for sounds in polysyllabi...Continue Reading
