7~11岁人工耳蜗植入儿童言语流畅性及其与口腔轮替速率的关系

The Correlation between Speech Fluency and Diadochokinetic Rate in Children Aged 7~11 Years with Cochlear Implantation

目的研究7~11岁人工耳蜗植入儿童言语流畅性及其与口腔轮替速率的关系。方法采集62例7~11岁人工耳蜗植入儿童在复述语言任务(以《唱歌篇》为复述语料)和口腔轮替测试任务(以/pataka/为测试语料)下的语音样本,分析其言语速率、构音速率、音节时长和停顿时长,ICF转换器获得各指标的损伤限定值,分析7~11岁人工耳蜗植入儿童的言语流畅性和口腔轮替速率;对两种任务下的言语速率、构音速率、音节时长和停顿时长进行偏相关分析。结果①人工耳蜗植入儿童两种任务下言语流畅性和口腔轮替速率的各指标均存在不同程度损伤,口腔轮替速率ICF平均损伤限定值为1.3±0.1,复述任务的言语流畅性ICF平均损伤限定值为1.0±0.3;②复述任务下言语速率、构音速率、音节时长与口腔轮替的言语速率、构音速率、音节时长存在中或低度相关(0.3<|r|≤0.8);复述任务的停顿时长与口腔轮替速率的言语速率和停顿时长呈低度相关(0.3<|r|≤0.5)。结论7~11岁人工耳蜗植入儿童存在言语流畅性不佳、口腔轮替速率较低的问题,构音器官运动不佳限制了其言语流畅性的提升。

Objective To explore the correlation between speech fluency and diadochokinetic rate in children aged 7~11 years with cochlear implant.Methods Speech samples were collected from 62 children aged 7~11 years with cochlear implant using language retelling task and diadochokinetic rate test task.Their speech rate,articulation rate,syllable duration and pause duration were analyzed.The data were input into ICF converter to obtain the impairment limit of each parameter and analyze the speech fluency and diadochokinetic rate characteristics.Partial correlation analysis was performed for speech rate,articulation rate,syllable duration and pause duration by two tasks.Results①For children with cochlear implant,the mean ICF impairment limit of diadochokinetic rate was 1.3±0.1,the mean ICF impairment limit of fluency in retelling was 1.0±0.3,with various degree of impairment in both tasks.②There was a moderate or low correlation between speech rate,articulation rate,syllable duration in retelling task and those in diadochokinetic rate task(0.3<|r|≤0.8).There was a low correlation between pause duration in retelling task and speech rate and pause duration in diadochokinetic rate task(0.3<|r|≤0.5).Conclusion The speech fluency and diadochokinetic rate of children aged 7~11 years with cochlear implant is underdeveloped,and the poor articulation movement ability limits their development of speech fluency.
