The purpose of this study was to examine the effect of fundamental frequency (F[0]) on stop consonant voice onset time (VOT). VOT was measured from the recordings of 56 young men reading phrases containing all 6 English voiced and voiceless stops in word-initial position across high-, medium-, and low-F[0] levels. Separate analyses of variance for the voiced and voiceless stops revealed no significant main effect for F[0] for the voiced stops but a significant F[0] effect for the voiceless stops. Across the voiceless stops, productions at high F[0]s displayed significantly shorter VOTs than productions at low or mid F[0]s. The findings indicated that researchers must take into account the F[0] level at which voiceless stop VOT is measured. (Contains 7 figures and 4 tables.)
