| Abstract | Acoustic studies of voice-onset-time (VOT) in aphasic's speech suggest that fluent aphasics' errors are misselected phonemic targets, whereas nonfluent aphasics' errors are of articulatory origin. However, caution must be used when extrapolating a theory from only 1 measure of articulation. The present experiment examined utterances produced by 5 43-67 yr old fluent aphasics, 5 52-69 yr old nonfluent aphasics, and 2 controls. VOT findings were replicated, and the duration of vowels preceding word-final stop consonants was examined as an index of the consonant's voicing category. The pattern of VOTs produced did not predict the pattern of vowel durations. Thus, VOT cannot be used to characterize more generally the output of the speaker. |
