在没有伴随听觉言语刺激的视音言语知觉的研究中，听力正常的成年人(NH；n=96)和听力严重到严重受损的成年人(IH；n=72)在孤立和句子中识别辅音-元音(CV)无意义音节和单词。语音知觉的测量指标为音素正确率和对简历传递的特征信息的比例，音素对词的正确率，音素对句子的正确率和音素替代熵的量。结果显示，IH组对语音信息的敏感性更高。对于IH组，传输的特征信息与孤立词分数有关，而对于NH组，与孤立词分数无关。在句子中的音素错误，IH组比NH组更加系统化。与NH组相比，IH组对简历的语音知觉的个体差异与单词和句子表现的相关性更高。结果表明，在某些个体中，有必要在没有听力的情况下感知语言可能与增强的视觉语音感知有关。
In this study of visual phonetic speech perception without accompanying auditory speech stimuli, adults with normal hearing (NH; n = 96) and with severely to profoundly impaired hearing (IH; n = 72) identified consonant-vowel (CV) nonsense syllables and words in isolation and in sentences. The measures of phonetic perception were the proportion of phonemes correct and the proportion of transmitted feature information for CVs, the proportion of phonemes correct for words, and the proportion of phonemes correct and the amount of phoneme substitution entropy for sentences. The results demonstrated greater sensitivity to phonetic information in the IH group. Transmitted feature information was related to isolated word scores for the IH group, but not for the NH group. Phoneme errors in sentences were more systematic in the IH than in the NH group. Individual differences in phonetic perception for CVs were more highly associated with word and sentence performance for the IH than for the NH group. The results suggest that the necessity to perceive speech without hearing can be associated with enhanced visual phonetic perception in some individuals.
