维吾尔族腭裂术后儿童无悬雍垂对塞音q影响的初步研究

A preliminary study on the influence of non-uvula on stop /q/ in uygur children after operation for cleft palate

目的:应用计算机语图,探讨维吾尔族儿童腭裂术后悬雍垂缺失对发q音的影响。方法:纳入维吾尔族腭裂术后儿童有悬雍垂20名;无悬雍垂14名,正常维吾尔族儿童60名,仿说维吾尔语音节[qa][qi][qu]的语音,所录语音经praat语音软件检测,将正常组儿童、腭裂术后有悬雍垂儿童、无悬雍垂儿童的语音样本通过独立样本t检验,两两比较。结果:腭裂术后无悬雍垂儿童与正常儿童相比较,被检音的音长(CD)短、音强(CE)低、共振峰F1、F3低(P<0.05),与术后有悬雍垂儿童相比较,被检辅音音强(CE)低、共振峰F1、F3高(P<0.05)。结论:维吾尔族腭裂修补术后儿童保留悬雍垂有利于/q/音的正常发出。

Objective:To study the effects of uvula loss on q pronunciation in Uygur children after repair of cleft palate using phonogram.Methods:20 children with and 14 without uvula after cleft palate repair,60 healthy children with normal uvula were included and simulated to pronounce uygur syllable[qa][qi]and[qu].The recorded pronounciation was detected by praat voice software.The pronounciation samples of the children of the 3 gorups were analyzed by independent sample T test and compared in pairs.Results:Compared with the healthy children,the children without uvula after cleft palate repair,the sound length(CD)was shorter,sound strength(CE)lower,F1 and F3 were lower(P<0.05),compared with children with uvula after operation,CE was lower,F1 and F3 were higher(P<0.05).Conclusion:The retention of uvula in uygur children after cleft palate repair is beneficial to the normal articulation of/q/sound.
