维吾尔族腭咽闭合功能不全患者语音清晰度及其辅音/r/声学特征的初步研究

摘要

Objective:To study the speech articulation and the consonant /r/acoustic features of articulation disorders caused by velopharyngeal insufficiency.Methods:According to “Uyghur speech articulation test scale”and the classification method used in Uyghur articulation disorders the articulation and characterization of consonant /r/of 31 cases with velopharyngeal insufficiency were examined,scored and classified.Results:The cases of mild(-x =81),moderate(-x =51)and severe(-x =21)voice disorder in the 31 patients were 9,12 and 10 respectively.Among the 3 groups,CD,CA,F1,F3 and F4 were different(P <0.05),F2 was not (P>0.05).Conclusion:“Uyghur speech articulation test scale”and speech articulation classification standard have certain clinical value in of the study of Uyghur articulation disorders.There are differences in pathological consonant acoustic parameters of consonant/r/between and patients with velopharyngeal insufficiency and the subjects with normal speech.%目的：初步研究因腭咽闭合功能不全而导致的语音障碍患者的语音清晰度以及辅音／r／的声学特征。方法：临床确定为腭咽闭合功能不全的31例患者依次朗读念词表中的词并对其实行清晰度测试、计分、分类、对词表中辅音／r／的声学分析和统计分析。结果：31例患者语音障碍轻度（珋x ＝81分）9人，中度（珋x ＝51分）12人，重度（珋x ＝21分）10人。对所得到的参数进行单因素 ANOVA 分析，比较3组患者的 CD、CA、F1、F3、F4差异有统计学意义（P ＜0．05）；F2差异无统计学意义（P＞0．05）。结论：病理性辅音／r／的声学参数与正常语音之间差异显著，建立的“维吾尔语语音清晰度测试词表”及语音清晰度分类标准在维吾尔语语音障碍研究领域中有一定的临床价值。
