Voice fundamental frequency modulates vocal response to pitch perturbations during English speech

摘要

Previous research has demonstrated task-dependent vocal responses to pitch perturbations during speech production. The present study investigated the effect of voice fundamental frequency (F_0)on the modulation of vocal responses during English speech. Randomized pitch shifts of ±100 or 200 cents during speaking were presented to English speakers. Results indicated larger vocal responses and shorter latencies at a high voice F0 than at a low voice F_0, but no significance diferences were observed for stimulus magnitude or direction. These findings suggest that the pitch-shift reflex during speech can be modulated as a function of voice F0.
