| Abstract(in English) | Previous studies of the perception of temporal structure in speech have mainly been investigated with auditory stimuli. In this study, to investigate the possibility of integration of the auditory and visual information in perceiving the temporal structure of speech, effects of additional face motion were examined. In Experiment 1, sensitivity to the temporal distortion in speech was found to be higher in auditory stimuli than visual stimuli in unimodal condition. Additionally, the results implied that the detection of temporal distortion in the bimodal condition with temporally consistent stimuli was mainly based on auditory information. In Experiment 2, the use of temporally inconsistent stimuli interfered with perception of temporal distortion. The degree of interference from the auditory stimuli was larger than the visual stimuli. The results suggest that the auditory information is dominant in the audio-visual integration for the detection of temporal structure. |
