Effect of Fundamental Frequency on Medial [+Voice] / [–Voice] Judgments

Abstract

Previous research has suggested that the direction of short-duration fundamental frequency (F₀) perturbations following consonants helps to signal consonant [+voice]/[––voice] (abbreviated as [voice]) status. It has been proposed that the [voice] cue corresponds to the direction and extent of F₀ perturbations relative to the overall intonation contour. A competing view, the low-frequency hypothesis, suggests that F₀ participates in a more general way whereby low-frequency energy near the consonant contributes to [+voice] judgments. Listeners identified multiple stimulus series, each varying in voice onset time and ranging from /aga/ to /aka/. The series differed in overall intonation contour as well as in the direction of F₀ perturbation relative to that contour. Consistent with one version of the low-frequency hypothesis, the F₀ value at voicing onset, rather than the relative direction of the F₀ perturbation, was the best predictor of [voice] judgments.
