173例功能性构音障碍患者辅音错误特点分析

目的：分析功能性构音障碍辅音错误特点，为语音治疗提供参考。方法对173例功能性构音障碍患者辅音错误按发音部位和发音错误类型进行归纳分类，找出其辅音错误特点。结果功能性构障碍中按发音部位统计舌尖中音的发生率最高，其次为舌尖前音、舌尖后音、舌面音、舌根音、双唇音、唇齿音，按发音错误类型排列顺序为置换>省略>歪曲，置换错误类型频数分布由高到低为：软腭化>齿龈化>硬腭化>鼻音化>齿背化>边音化>口唇化。结论功能性构音障碍成人比言语发育期患者辅音错误率降低，但治疗难度高且周期长。言语发育时期应及早干预，否则构音障碍可能长期存在。

Characteristics of consonant errors in 173 cases of functional articulation disorders

Objective To analyze the characteristics of consonant errors in functional articulation disorders (FAD). Methods The characteristics of consonant errors was examined in 173 patients with FAD,which was classified by place and manner of articulation. Results The sequence in descending order of error occurrence by the place of articulation was:alveolar,dental,lingual,palatal,velar,bilabial,labiodental. The sequence in descending order of error occurrence by the error type of articulation was:substitute,omit,distort. Conclusion The occurrence of FAD in adults is lower than that in speech development children but harder improved. So FAD should be treated in time,otherwise it may exist for a long time.
