This report presents a brief study into sex differences of speakers in the voice onset time of English plosives that are stressed in both word-initial and pre-vocalic positions. 36 isolated words were spoken by 5 men (age range 25 to 37 yr., M: 34.2 yr.) and 5 women speakers (age range 28 to 38 yr., M: 32.6 yr.) who were subjects. Analysis showed that the women speakers had on the average relative to the men, longer voice onset time values for voiceless plosives and shorter voice onset time values for the voiced plosives.
