Voice-onset time as a clue to the nature of Broca speech errors.
Blumstein, Cooper, Goodglass, Statlender, and Gottleib (Brain and Language, 9, 153-170 (1980] attempt to determine by an examination of the VOTs of aphasic speakers whether Broca's aphasics make phonemic substitutions in addition to their well-known phonetic errors. There are a number of problems with this study, mostly due to an apparent failure to fully appreciate the fact that VOT is a cover term for several acoustic features. It is suggested that VOT measurement in any given position in a word cannot solve this problem and that future studies should include glottographic observations as well as VOT measurements made in all positions in the word.
