摘　　要：目的　研究腭裂术后非腭咽闭合功能不全型异常语音的音声特征。方法　应用美国Kay 780 0语图仪分析系统 ,对 32例腭裂术后患者中非腭咽闭合功能不全的异常语音语图与 3例正常语音语图进行比较分析。结果　腭裂术后非腭咽闭合功能不全的异常语图表现主要有 3种类型 ,以“噪音化”多见。Objective The phonetic features were studied for non velopharyngeal dysfunction in postoperative patients with cleft palate.Methods The features of velopharyngeal competency of 32 postoperative patients with cleft palate were analyzed with KAY 7800 sound spectrograph,compared with characteristic of 30 subjects with normal phonogram.Results There were three types of abnormal phonogram for the postoperative patients of cleft palate with velopharyngeal competence. The heavy noise was a common sight.Conclusion An analytic system of sound spectrography has certain value for evaluation of phonic function in cleft palate patients.
