目的对语前聋人工耳蜗植入患儿的语音识别情况进行研究,初步探讨耳蜗植入者的语音识别情况及其影响因素。方法实验对象包括40名植入语前聋人工耳蜗儿童及20名听力正常儿童,采用口语给声、开集测试的方式测试其韵母及声母识别率,研究植入年龄和教育交流方式对结果的影响。结果(1)耳蜗植入儿童的韵母识别率高于其声母识别率;(2)3岁前植入的儿童的语音识别率高于3岁后的植入儿童,且植入年龄与语音识别率呈负相关;(3)采用听觉口语法的儿童比采用综合交流法的儿童,具有更好的语音识别率。结论对于耳蜗植入儿童而言,声母比韵母更难掌握;植入时间较早、利用口语交流的儿童可以从人工耳蜗中获得更多的益处。
Objective To study the speech recognition of cochlear implants in prelingual deaf patients and to investigate the speech recognition of cochlear implants and its influencing factors. Methods The subjects included 40 children with cochlear implants and 20 normal children with hearing impaired children. The rates of vowel consonants and initial consonants were tested using the oral acoustics and open-label test, and the effects of implanting age and educational exchange on the outcome influences. Results (1) The vocal recognition rate of cochlear implanted children was higher than that of initial consonants. (2) The speech recognition rate of children implanted before 3 years old was higher than that of implanted children after 3 years old, and the age and speech recognition The rate was negatively correlated; (3) children with auditory oral method had better speech recognition rate than those who adopted the integrated communication method. CONCLUSIONS: Consonants are harder to master than cochlear implants for children with cochlear implants; implants earlier and children who use oral communication may benefit more from cochlear implants.
