This study assessed the auditory/visual speech perception abilities of profoundly hearing-impaired subjects using the cochlear implant (CI) developed at the House Ear Institute with those of patients using traditional hearing aids (HA). Audio-video tape recordings of consonant-vowel-consonants (CVCs) consisting of: ten vowels in the context/mvm/, vowel-consonant-vowels (VCVs) consisting of twenty-four consonants in the context/ C /, and the CID Everyday Sentences were presented through auditory, visual, and auditory-visual modes. Subjects' verbal responses to the stimuli were transcribed by the experimenters. Statistical analyses of the data revealed significant differences for groups, stimuli, and conditions. Inspection of the subject's confusion matrices revealed that both groups used closed-bilabial, velar, dental, labial, and easy to see/hard to see features based on place of articulation in the visual mode. Salient features in the auditory mode for the CI group were duration, sonorancy, and some manner attributes, while the HA subjects used these features as well as sibilancy and voicing. Both groups integrated auditory and visual cues to improve scores in the auditory-visual condition. These findings have implications for future developments of auditory prostheses and auditory rehabilitation programs.
本研究评估了使用豪斯耳科研究所研发的人工耳蜗（CI）的极重度听力受损受试者与使用传统助听器（HA）的患者的听觉/视觉言语感知能力。由以下内容组成的辅音-元音-辅音（CVC）、元音-辅音-元音（VCV）和CID日常语句的音频视频录像通过听觉、视觉和听觉-视觉模式呈现：在/mvm/语境中的十个元音、在/C/语境中的二十四个辅音组成的元音-辅音-元音，以及CID日常语句。实验人员记录了受试者对刺激的言语反应。数据的统计分析显示，在组、刺激和条件方面存在显著差异。对受试者混淆矩阵的检查表明，两组在视觉模式下都使用了基于发音部位的双唇闭塞音、软腭音、齿音、唇音以及易于看见/难以看见的特征。人工耳蜗组在听觉模式下的显著特征是时长、响亮度和一些发音方式属性，而使用助听器的受试者除了这些特征外还使用了咝音和浊音。两组都整合了听觉和视觉线索以提高听觉-视觉条件下的得分。这些发现对未来听觉假体和听觉康复项目的发展具有启示意义。
