Auditory Long Latency Responses to Tonal and Speech Stimuli.
Purpose: The effects of type of stimuli (i.e., nonspeech 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: Young adu...

Method: Young adult men (n = 15) and women (n = 15), all with normal hearing, participated. P1-N1-P2 components were evoked with the following stimuli: 723Hz 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 but with a shift 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). Women had significantly shorter latencies for only the P2 component (p < .05). For the tonal versus speech stimuli, PI amplitudes were significantly smaller, and N1 and P2 amplitudes were significantly larger (p < .05). There was no significant effect of gender on the PI, N1, or P2 amplitude (p > .05). Condusion: These findings are consistent with the notion that spectrotemporal characteristics of nonspeech and speech stimuli affect PI -- NI -- P2 latency and amplitude components. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
