The purpose of this study is to discuss the effect of speech rate in the cognitive process of speech sound. To serve this purpose, we observed the features of ERP elicited by listening to nonwords with various speech rates and different pitch patterns. Three kinds of speech rate were used: fast, normal, and slow. Two kinds of pitch patterns were also chosen: up and down. Three Japanese participated in this experiment.
As a result, when the subjects listened to nonwords at the normal speech rate, the peak latency of the P2 tended to advance in comparison to nonwords at fast or slow speech rates. Moreover, when the subjects listened to nonword with a flat pitch pattern (normal), the peak latency of the P2 also tended to advance in comparison to nonwords with an up or down pitch pattern.
