摘要
联合应用鼻咽镜、语图仪与计算机技术，对４５例腭裂术后腭咽闭合不全患者保守治疗前后的语音进行评价。结果表明：戴阻塞器并行语音训练２．５～３年，腭咽闭合不全改善率（ＩＲＶＰＩ）达３３．３３％，语图仪分析示语图谱纹较前清晰，着色加深，共振峰值（Ｆ２，Ｆ３）接近正常，嗓音起始时间（ＶＯＴ）负值极少出现，提示腭咽闭合功能良好，口腔不良习惯改正。鼻咽镜、语图仪与计算机分析技术用于腭裂病理性语音分析，评价矫治效果具有重要的临床意义，将提高对腭裂语音的矫治水平。
ァ he speech of 45 cases with velopharyngeal incompetence (VPI) were evaluated by combining application of nasop haryngofiberoscope (NPF) and computerspectrographic analysis system (CSAS) after cleft palate operation and conser vatives peech therapy with using cleft palate obturators.The results showed:Improving rate of velopharyng eal incompetence (IRVPI) was close to 33.33% after 2.5～3 years therapy.The spectrographic analysis showed aclearer,and darken frequ ency band,normal resonance peaks(F2,F3) and seldom appearance of negative value of voice origination time (VOT).The above indicated that patients had achieved adequate velopharyngeal competence (VPC) and good speech habit.It has important signifi cances and greatly improve speech therapy level to apply NPF and CSAS to analysing pathologic speech and evaluating therapic effect.
