摘要： 目的：初步掌握健康儿童和腭裂术前患者汉语普通话语音中不送气辅音的声学特征。方法：应用VS-9700语音工作站(1.0版)分别对22名正常儿童和19名腭裂患者的汉语普通话中的擦音（［f］、［s］、［s］、［c］、［x］）和不送气塞擦音（［ts］、［ts］、［tc］）进行声学分析，观察不送气辅音的语图模式特征，分析各自的特点。结果：腭裂患者的不送气塞擦音语图模式上无塞音特征，只有擦音特征，其强频区位置下移。腭裂患者和正常儿童的擦音语图模式区别不明显，仅表现为强频区位置的下移。结论：腭裂患者的不送气塞擦音语图模式上只有擦音特征，擦音语图模式除能量下降外，和正常儿童比较无明显变化。

Abstract: Objective To explore the spectro-mode features of unaspirated consonants of Chinese Putonghua produced by healthy, normal children and children with cleft palate. Methods The voices of 22 healthy, normal children and that of 19 cleft palate children before operation were compared by VS-9700 spectrography; the features in unaspirated affricative （［ts］,［ts］,［tc］）and fricative (［f］, ［s］, ［s］, ［c］, ［x］) of Chinese Putonghua were observed, respectively. The values of the frequency of the normal children and the children with cleft palate were analyzed. Results No obvious plosive features were observed in patients with cleft palate in speaking but only fricative feature was found. The differences reflected in the fricative (［f］, ［s］, ［s］, ［c］, ［x］) spectrum of the normal and preoperation cleft palate children were not distinctive , and showed that position of the heavy frequency was lowered. Conclusion The spectro-mode features in affricative of speech disorders associated with clefting have no obvious plosive features in speaking and only fricative features. The spectro-mode features in fricative between the normal children and the children with cleft palate are not distinctive.
