This study investigated the effect of self-triggered voice fundamental frequency (F0) feedback perturbation on auditory event-related potentials (ERPs) during vocalization and listening. Auditory ERPs were examined in response to self-triggered and computer-triggered -200 cents pitch-shift stimuli while participants vocalized or listened to the playback of their self-vocalizations. The stimuli were either presented with a delay of 500-1000 ms after the participants pressed a button or delivered by a computer with an interstimulus interval of 500-1000 ms. Results showed that self-triggered stimuli elicited larger ERPs compared with computer-triggered stimuli during both vocalization and listening conditions. These findings suggest that self-triggered perturbation of self-vocalization auditory feedback may enhance auditory responses to voice feedback pitch perturbation during vocalization and listening.
