摘　　要：目的研究4~5岁人工耳蜗植入儿童和同龄健听儿童易混淆语音的发音状况。方法选取4~5岁人工耳蜗植入儿童和健听儿童各8名,使用Cool edit pro录音软件录制下其发出易混淆音的音频。将录制的音频输入Praat语音分析软件,对被检音的各项参数进行声学分析。将数据导入SPSS20.0软件,进行t检验统计学处理,比较人工耳蜗植入儿童和健听儿童近音同调单字、同音不同调词的各项声学参数的差异。结果人工耳蜗植入儿童各近音同调单字和同音不同调词的错误率均显著高于健听儿童(P<0.05)。对于"测"与"撤"、"权"与"钱"两组音:人工耳蜗组和健听组录音的声学参数均无明显的统计学差异(P>0.05)。对于"羊"与"娘","去"与"气","切"与"贴"三组音:健听组录音的各项声学参数有明显的统计学差异(P<0.05),人工耳蜗组的各项声学参数无明显的统计学差异(P>0.05)。结论人工耳蜗植入儿童较健听儿童更易混淆易混淆音,语训时应针对易混淆音加强区分与训练。Objective To study the pronunciations of confounding speech in children aged 4-5 years with cochlear implants and normal children of the same age. Methods For 8 children with cochlear implants and 8 normal children aged 4-5 years, the Cool edit pro recording software were used to record the confusing sounds they make. The recorded audio was put into Praat voice analysis software, and acoustic analysis was performed on the parameters of the detected sounds.The data were imported into SPSS 17.0 software for t test statistical processing to compare whether there were significant differences in acoustic parameters of words with similar tone between the cochlear implant group and the normal group. Results The error rate of relative sound and different tone separate words and same sound different tone word groups in children with cochlear implant is higher than that in normal children.For the two groups of words "ce"and"che","quan"and"qian": there was no significant difference in acoustic parameters between the normal group and the cochlear implant group(P>0.05).For the three groups of wo rds"yang"and"niang","qu"and"qi","qie"and"tie": there were significant statistical differences in acoustic parameters between the normal group(P<0.05) while no statistically significant difference in the acoustic parameters of the cochlear implant group(P>0.05). Conclusion Children with cochlear implant are different from normal children in their pronunciations of confusable sounds. Compared with normal children, cochlear implant children are more likely to confuse these confusable sounds.
