Audio-Visual interaction in speech perceptionn in subjects with hearing

通过测量McGurk效应来检验听力减退受试者言语知觉中的视听交互作用。在McGurk效应中，听觉语音音节的知觉识别受到可视语音音节同时呈现的影响。在不同年龄和不同母语背景的受试者中都发现了这种效应。在本研究中，我们考察了恶化的听觉刺激对McGurk效应的影响。虽然这一效应受到劣化的听觉刺激的影响，但实验结果似乎反映了当用于语音识别的听觉线索退化时，视觉线索在语音识别中起着更重要的作用，这一结果表明McGurk效应可能被用作语音知觉中的视听交互的指示器。

Audio-Visual interaction in the speech perception for subjects with deteriorated hearing was examined through the measurements of McGurk effects. In the McGurk effect, perceptual identification of auditory speech syllables is influenced by simultaneous presentation of discrepant visible speech syllables. This effect has been found in subjects of different ages and with various native language backgrounds.In the present study, the effects of deteriarated auditory stimulus on McGurk effects were examined. Although this effects were infuluenced by the deteriorated audio-stimuli, the results obtained appeared to reflect that the visual cue for speech recognition played more important role when the auditory cue for speech recognition was degraded.The obtained results suggest that McGurk effects possibly can be use as an indicator for the audio-visual interaction in the speech perception.
