腭裂术后功能性语音障碍发音特点研究

目的为指导腭裂术后语音障碍的诊断及语音治疗。方法选择５０例腭裂术后由不良发音习惯所致的功能性语音障碍患者，进行汉语语音清晰度测试，计算各辅音误念率，找出各类辅音发音错误特点，根据各类辅音误念率特点作统计学处理以观察各类辅音错误发生率之间的关系。结果塞擦音如ｊ、ｚ、ｚｈ等的误念率最高（平均６７３％），塞音如ｂ、ｄ、ｇ、ｋ等的误念率则明显低于塞擦音（平均３９７％）。两类辅音间的误念率有明显差别（Ｐ＜０００１）。提示腭裂术后功能性语音障碍以塞擦音错误为主。结论这类患者并非二次手术的适应证，而应以语音训练为主要治疗手段。

A study on the characteristics of articulation for functional speech problem after cleft palate surgery

Objective To analyze the characterisctics of articulatory errors for the patients with speech problem and whose anatomic or physiologic defect such as velopharyngeal insufficiency were not indicated after cleft palate surgery.Methods Fifity patients with functional speech problem outlined above were tested using articulation test in chinese. The frequency of articulatory errors of all consonants was calculated. The interrelativity of the rate of affricates and plosives errors was analyzed.Results The frequency of affricates (j. z. ch. zh. et al)errors was higher than plosive's (b.d.g.k.et al). The difference of the rate of affricates and plosives errors was signicant, statiscally ( P <0 001).Conclusion It is suggested that the frequency of affricates errors was principal in this type of patients. They will be cured by speech training.
