A consonant confusion study was undertaken on a multiple-channel cochlear implant patient using a wearable speech processing device. This patient suffered from total bilateral deafness acquired postlingually. The consonants /b/, /p/, /m/, /v/, /f/, /d/, /t/, /n/, /z/, /s/, /g/, /k/ were presented in a VCV context with the vowel /a/ as in father by a male and female speaker under three conditions: lipreading alone; electrical stimulation alone using the wearable speech processor and multiple-channel cochlear implant; lipreading in conjunction with electrical stimulation. No significant difference was detected between the results for the male and female speakers. The percentage correct scores for the pooled results of both speakers were lipreading alone--30%; electrical stimulation alone--48%; lipreading with electrical stimulation--70%. Performance was significantly better for lipreading with electrical stimulation than for lipreading alone and for electrical stimulation alone than for lipreading alone. An information transmission analysis demonstrated the effective integration of visual and auditory information for lipreading with electrical stimulation. There was a significant improvement in performance for the electrical stimulation alone condition over the 2 months of the study in contrast to no such improvement for lipreading alone.
使用可穿戴语音处理设备，对一名多通道人工耳蜗植入患者进行了辅音混淆研究。该患者患有双侧全聋，是在语言习得后获得的。辅音/b/、/p/、/m/、/v/、/f/、/d/、/t/、/n/、/z/、/s/、/g/、/k/在“元音-辅音-元音”（VCV）语境中呈现，其中元音为/fɑːðə(r)/中的/a/，由一名男性和一名女性说话者在三种条件下读出：仅唇读；仅使用可穿戴语音处理器和多通道人工耳蜗进行电刺激；唇读与电刺激相结合。未检测到男性和女性说话者的结果之间存在显著差异。两位说话者汇总结果的正确得分百分比分别为：仅唇读——30%；仅电刺激——48%；唇读与电刺激相结合——70%。唇读与电刺激相结合的表现明显优于仅唇读，仅电刺激的表现也明显优于仅唇读。信息传输分析表明，唇读与电刺激相结合时，视觉和听觉信息得到了有效整合。在研究的2个月期间，仅电刺激条件下的表现有显著改善，而仅唇读则没有这种改善。
