  • Title: Sex-related differences in vocal responses to pitch feedback perturbations during sustained vocalization.
    Author: Chen Z, Liu P, Jones JA, Huang D, Liu H.
    Journal: J Acoust Soc Am; 2010 Dec; 128(6):EL355-60. PubMed ID: 21218857.
    Abstract:
    The present study assessed the effect of sex on voice fundamental frequency (F(0)) responses to pitch feedback perturbations during sustained vocalization. Sixty-four native-Mandarin speakers heard their voice pitch feedback shifted at ± 50, ± 100, or ± 200 cents for 200 ms, five times during each vocalization. The results showed that, as compared to female speakers, male speakers produced significantly larger but slower vocal responses to the pitch-shifted stimuli. These findings reveal a modulation of vocal response as a function of sex, and suggest that there may be a differential processing of vocal pitch feedback perturbations between men and women.
