河南地区腭裂术后患者病理性语音特点探讨

目的 通过对河南地区腭裂术后患者与舌位关系密切的异常语音构音特点及元音共振峰值的分析,揭示河南地区腭裂术后患者病理性语音的声学特点。方法 采集100份正常语音样本（正常语音组）及121份腭裂术后患者的语音样本（腭裂语音组）,根据录音资料得出患者的异常构音情况,经计算机语音工作站（computer speech lab,CSL）对2组语音样本的6个元音（a、o、e、i、u和ü）的前3个共振峰频率值（F1、F2、F3）进行测量分析,采用SPSS17.0软件包对数据进行两独立样本t检验。结果 腭裂语音组的异常语音出现率按构音点分别为舌尖前音占21.9%,舌尖中音占5.2%,舌尖后音占21.6%,舌面音占19.2%,舌根音占12.9%,舌前背音占6.6%;正常语音组与腭裂语音组在元音/a、o、e、u/的第二共振峰（F2）数值统计上,差异均无显著性（P>0.05）。2组在元音/i、ü/的第二共振峰（F2）差异有统计学意义（P<0.05）。2组在元音/a、o、e、i、u/的第一共振峰（F1）的差异均无统计学意义（P>0.05）。2组在除元音o外,第三共振峰（F3）差异均有显著性（P<0.05）。结论 河南地区腭裂术后异常语音患者的异常音,主要出现在辅音中的舌尖前音、舌尖后音及舌面音;河南地区腭裂术后腭咽闭合不全患者发音时与正常人相比,开口度方面无明显异常,主要是软腭上抬不足、舌尖上翘过高、r化音过重。

Study on articulation characteristics of patients after cleft palate repair in Henan province

PURPOSE: To establish the pathological speech characteristic of patients after cleft plate repair in Henan province by unusual speech frequency and vowel formants. METHODS: One hundred normal speech patients and 121 patients after cleft palate repair were selected, their formant frequency of vowels/ a,o,e,i,u,ü/ were obtained. The pathological speech frequency was collected in 121 postoperative patients. The acoustic features of the vowel were compared by SPSS17.0 software package with two independent sample t test. RESULTS: According to articulation position, 21.9% of misarticulation of postoperative patients occurred in dental consonants, 5.2% in retroflex consonants, 21.6% in alveolar consonants, 19.2% in palatal consonants, 12.9% in velar consonants and 6.6% in dorsum consonants. The average value of F2 of/a, o, e, u/did not show significant difference between the two groups (P>0.05).The difference of average value of F2 of /i,ü/ was significant (P<0.05). The average value of F1 of/a, o, e, I, u/did not show significant difference between the two groups (P>0.05).Except /a/,the average value of F3 of vowel /o, e, i, u, ü/showed significant difference between the two groups (P<0.05). CONCLUSIONS: Misarticulation of patients after cleft palate repair in Henan province mainly occurred in dental consonants, alveolar consonants and palatal consonants; tongue over curly can be observed in operated patients with cleft palate. There was no significant difference between the two groups in mouth opening.
