PURPOSE: The effects of type of stimuli (i.e., non-speech vs. speech), speech (i.e., natural vs. synthetic), gender of speaker and listener, speaker (i.e., self vs. other), and frequency alteration in self-produced speech on the late auditory cortical evoked potential were examined. METHOD: Normal hearing young adult males (n = 15) and females (n = 15) participated. P1-N1-P2 components were evoked with the following stimuli: 723 Hz tone bursts; naturally produced male and female /a/ tokens; synthetic male and female /a/ tokens; an /a/ token self-produced by each participant; and the same /a/ token produced by the participant shifted in frequency. RESULTS: In general, P1-N1-P2 component latencies were significantly shorter when evoked with the tonal stimulus versus speech stimuli and natural versus synthetic speech (p < .05). Females had significantly shorter latencies for only the P2 component (p < .05). P1 amplitudes were significantly smaller while N1 and P2 amplitudes were significantly larger for the tonal versus speech stimuli (p < .05). There was no significant effect of gender on the P1, N1, or P2 amplitude (p > .05). CONCLUSIONS: These findings are consistent with the notion that spectro-temporal characteristics of non-speech and speech stimuli affect P1-N1-P2 latency and amplitude components. |
