摘　　要：本研究通过分析自闭症儿童和典型发展儿童的语音参数,探讨自闭症儿童的发音特点。被试模仿标准播音员发音,内容覆盖了普通话的声母、韵母、声调以及一篇短文。本研究提取并分析了单音节时长、五度调值、元音共振峰,以及句子发音的语速和最大音强标准差参数。研究表明,相较于典型发展儿童自闭症儿童的语音参数个体差异较大,且部分自闭症儿童的各语音声学参数的稳定性不如典型发展儿童。本研究结果可用于自闭症儿童的发音康复训练以及训练效果评估。The study discusses the pronunciation characteristics of autistic children by analyzing the phonetic parameters of autistic children and typical developmental children.The subjects imitated the pronunciation of a standard broad caster,the content of imitation covering the initials,finals,tones and a short Putonghua passage.The study extracted monosyllabic duration,pentatonic value,vowel formant,speech speed and maximum intensity standard deviation parameters of sentence pronunciation.The results show that compared with typical developing children,the individual differences of speech parameters of autistic children are large,and the stability of speech acoustic parameters of some autistic children is not as stable as typical developing children.The results of this study can be used for pronunciation rehabilitation training and training effect evaluation of autistic children.
