腭裂病人序列治疗中元音的频谱分析

AN ANALYSIS OF THE SPECTRUM OF VOWELS IN THE SEQUENCE THERAPY FOR PATIENTS WITH CLEFT PALATE

①目的 分析腭裂病人序列治疗中元音的频谱特点 ,为腭裂病人的语音评价及语音矫治提供理论及临床上的指导。②方法 应用语图仪对 10例健康儿童、30例腭裂病人、33例腭裂手术后病人及 16例语音矫治后腭裂病人的 4个单元音进行检查 ,对其前 3个共振峰减弱和 (或 )缺失率进行统计分析。③结果 腭裂术前组与腭裂术后组 [i],[u]的共振峰减弱和 (或 )缺失率明显高于对照组 (χ2 =7.6 6 9～ 15 .6 10 ,P <0 .0 5 ) ,术后组与语音矫治后组比较差异也有显著性 (χ2 =9.0 10 ,5 .738,P <0 .0 5 )。④结论 腭裂病人序列治疗中元音频谱分析有很大使用价值与临床意义。

Objective\ To analyze the spectrum of vowels in the sequence therapy of patient with cleft palate in order to provide an objective basis for speech evaluation and correction. \ Methods\ 4 vowels were examined by spectrography in 10 healthy children, 30 patients with cleft palate, 33 postoperative patients for cleft palate and 16 patients after speech correction. The decrease and/or disappearance of the first three formants (F 1,F 2,F 3 ) were analyzed. \ Results\ The rate of decrease and/or disappearance of formants in preoperative group and postoperative group was significantly higher than that of the control group ( χ 2= 7.669 -15.610,P <0.05). But there was significant difference between postoperative group and speech correction group( χ 2= 9.010 ,5.738,P <0.05).\ Conclusion\ It is of great significance, both theoretically and clinically, to analyze the spectrum of vowels in the sequence therapy of patient with cleft palate.
