The perception of phonologically significant speech pattern contrasts was measured in normally hearing subjects who were presented with F0 contours alone, speechreading alone, and the two in combination. For the suprasegmentals and final consonant voicing, perception in the combined condition was dominated by F0. For the vowel, consonant place, and final consonant continuance contrasts, perception in the combined condition was dominated by vision. For initial consonant voicing and continuance, however, there was clear evidence of interaction between F0 and speechreading. Here, the combined score was higher than either of the single-modality scores, and also higher than could be predicted on the assumption that the auditory and visual channels act as statistically independent channels of information.
在正常听力受试者中测量了对语音学上显著的言语模式对比的感知，这些受试者分别仅呈现F0轮廓、仅唇读以及两者结合的情况。对于超音段和末尾辅音浊音，在组合条件下的感知主要由F0主导。对于元音、辅音位置和末尾辅音延续对比，在组合条件下的感知主要由视觉主导。然而，对于初始辅音浊音和延续，有明确证据表明F0和唇读之间存在相互作用。在此，组合得分高于任何一种单一模式得分，并且也高于基于听觉和视觉通道作为统计上独立信息通道这一假设所预测的得分。
