ERP correlates of the magnitude of pitch errors detected in the human voice

► Distinct patterns of vocal responses occurred following hearing small versus large pitch shifts in voice auditory feedback. ► P1 amplitude increased in a non-specific manner in response to frequency-altered feedback. ► Differential N1 amplitude modulation occurred following small versus large pitch shifts. ► Variance in P2 amplitude was predicted by vocal response magnitude. ► N2 amplitude increased as pitch shift magnitude increased.
