Voice fundamental frequency modulates vocal response to pitch perturbations during English speech.
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 F(0) than at a low voice F(0), but no significance differences 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 F(0).
