Objective Auditory feedback has been demonstrated to play an important role in the control of voice fundamental frequency (F0), but neural mechanisms underlying this control process are poorly understood.The present cross-language study was to examine whether there is a language-dependent neural processing of auditory feedback by measuring event-related potentials (ERPs) to pitch perturbations during sustained vocalizations of Cantonese and Mandarin speakers.Methods Native speakers of Cantonese and Mandarin participated in this experiment.They were asked to sustain a vocalization of a vowel sound/u/at their comfortable habitual F0 level for about 5 s, during which their voice pitch feedback was unexpectedly shifted 5 times (-50,-100,-200, or-500 cents, 200 ms duration) and fed back instantaneously to them over headphones.The ERPs to these pitch-shifted stimuli were measured and analyzed across conditions.Results Significantly larger amplitudes of P2 were produced by Cantonese speakers as compared to Mandarin speakers when voice pitch feedback was shifted from 200 to 500 cents, while no significant differences were found in P2 amplitude between them in the case of 50 and 100 cents stimuli.In addition, a systematic change of P2 amplitude across pitch perturbation magnitude was found for Cantonese speakers but not for Mandarin speakers.Conclusion Neural representations of pitch errors in voice F0 control can be modulated by subjects exposure to different languages, and differential effects of pitch perturbation magnitude on the cortical processing of auditory feedback between Mandarin and Cantonese speakers may be related to the specific tonal features of these two languages.
