The benefit derived from visual cues in auditory-visual speech recognition and patterns of auditory and visual consonant confusions were compared for 20 middle-aged and 20 elderly men who were moderately to severely hearing impaired. Consonant-vowel nonsense syllables and CID sentences were presented to the subjects under auditory-only, visual-only, and auditory-visual test conditions. Benefit was defined as the difference between the scores in the auditory-only and auditory-visual conditions. The results revealed that the middle-aged and elderly subjects obtained similar benefit from visual cues in auditory-visual speech recognition. Further, patterns of consonant confusions were similar for the two groups.
对20名中度至重度听力受损的中年男性和20名老年男性，比较了视听语音识别中视觉线索带来的益处以及听觉和视觉辅音混淆模式。在仅听觉、仅视觉和视听测试条件下，向受试者呈现辅音-元音无意义音节和CID句子。益处被定义为仅听觉条件和视听条件下得分的差异。结果显示，中年和老年受试者在视听语音识别中从视觉线索获得的益处相似。此外，两组的辅音混淆模式相似。
