学龄前自闭症儿童的韵律特征研究

The Prosodic Characteristics of Preschool Children with Autism

目的探讨自闭症儿童声调语调的声学特点,为其语言训练提供参考。方法选取学龄前自闭症儿童与正常儿童各20例,通过比较声调语调发音的声学参数,探讨自闭症儿童的韵律特征。结果自闭症儿童四个声调的F_0均显著大干正常儿童(P<0.05);自闭症儿童陈述句的F_0显著大干正常儿童(P<0.05),起伏度极显著小于正常儿童(P<0.01);自闭症儿童疑问句的起伏度极显著大干正常儿童(P<0.01);自闭症儿童的陈述句和疑问句在F_0、F_0SD、起伏度上均无显著性差异(P>0.05)。结论对自闭症儿童进行语训时,可从音高控制缺陷这一角度出发,对韵律障碍进行针对性训练。

Objective To explore the acoustic characteristics of children with autism and provide a reference for their language training. Methods The study focused on children with and without autism, by comparing the acoustic parameters of tone and intonation to each group.in which there were twenty children respectirely. Results Children with Autism＇s four tones F0 were significantly higher than normal children（P〈0.05）. Autistic children＇ s F0 of declarative sentence was also significantly higher than normal children（P〈0.05）, while intonation fluctuations were significantly lower than normal children（P〈0.01）.Autistic children＇s intonation fluctuations of interrogative sentences were significantly higher than the normal children（P〈0.01）.However, there were no significant differences in F0,FoSD, and intonation asperity of the autistic children＇s declarative and interrogative sentences （P〉0.05）. Conclusions For children with autism,we should provide specific training for prosodic disorder from the perspective of pitch control.
