目的研究新疆维吾尔族腭裂患者术后元音共振峰特点。方法采集32份维吾尔族正常语音儿童语音样本(正常语音组)和27份腭裂患者术后语音样本(术后语音组),运用praat软件对样本中的8个元音的第一共振峰(F1)和第二共振峰(F2)进行测量分析。结果术后语音组和正常语音组在元音/a,o,u/的第二共振峰F2差异均无统计学意义(P>0.05)。两组在元音/y,i,e,,/的第二共振峰F2差异有统计学意义(P<0.05)。两组在元音/a,,o,u,,y,e,i/的第一共振峰F1的差异均无统计学意义(P>0.05)。结论维吾尔族腭裂术后腭咽闭合不全患者发音时与正常语音儿童相比存在舌后缩现象,在发音开口度方面维吾尔族腭裂术后患者与正常语音儿童相比无差异。
Objective To study the characteristics of vowel formant in patients with cleft palate in Xinjiang Uigur. Methods Twenty-two phonetic samples (normal phonetic group) and 27 phrenic samples (postoperative phonetic group) were collected from Uygur normal speech children. Praat software was used to analyze the first formant (F1 ) And the second formant (F2) were measured and analyzed. Results There was no significant difference in the second formant / a, o, u / between the voice group and the normal voice group after operation (P> 0.05). The difference of the second formant F2 between vowels / y, i, e, and / was statistically significant (P <0.05). There was no significant difference in the first formant F1 between the two groups in vowels / a, , o, u, , y, e, i / (P> 0.05). Conclusions There is tongue retraction in uygur palate patients with velopharyngeal insufficiency compared with children with normal speech sounds. Uyghur patients with cleft palate surgery have no difference in pronunciation opening degree compared with normal speech children.
