Voice onset time production in French-speaking aphasics.
VOT productions were compared for 5 Broca's aphasics and 5 Wernicke's aphasics to those for a group of 5 normal subjects of similar age. Phonetic errors were produced by both types of aphasic patients, but not by normal controls. Although previous studies have found significantly more phonetic errors in VOT production for Broca's aphasics, this study did not. Both Broca aphasics and Wernicke aphasics had somewhat less overall average difference in VOT between voiced and voiceless consonant pairs than normal speakers. Standard deviations associated with the VOT productions were also greater for both aphasic groups than for normal subjects. The results of this study are considered in light of the previous literature.
