Abstract
We measured the voice onset time (VOT) of word initial voiced (/b/, /d/, /g/) and voiceless (/p/, /t/, /k/) consonants spoken by four subjects with laryngeal disorders.
The VDTs of voiced consonants which exceeded a normal category boundary between voiced and voiceless consonants were frequently found in two out of four subjects. Perceptual confusion between voiced and voiceless consonants was apt to be more common when the voiced consonants exceeded this boundary.
The VDT's of voiceless consonants did not differ significantly from normal VOT.
