目的研究腭裂裂隙面积与腭裂患者代偿性不良构音习惯间的相关性。方法测定17例腭裂患者的腭部和裂隙面积,计算裂隙的面积比;运用声学软件测定5个元音/a/、/i/、/o/、/e/、/u/的第一(F1)、第二(F2)、第三(F3)共振峰值。结果裂隙面积比与术前元音/e/的F1、F2、F3回归分析有显著意义,而且术前元音/e/的F1值与裂隙面积比呈正相关。元音/a/、/i/、/o/、/e/、/u/术前与术后各自的F1、F2、F3比较,均无显著性差异。结论裂隙面积比越大,患者的不良发音习惯越严重,治疗中需注重纠正多年来形成的不良发音习惯才能达到较好的语音改善效果。
Objective To study the correlation between cleft palate area and compensatory dysarthria in cleft palate patients. Methods The palatal and fissure areas of 17 patients with cleft palate were measured and the area ratio of fissures was calculated. The acoustic properties of 5 vowels / a /, / i /, / o /, / e /, / u / F1), second (F2), third (F3) resonance peak. Results The fracture area ratio was significantly correlated with the F1, F2 and F3 regression analysis of preoperative vowels / e /, and the preoperative vowels / e / F1 values were positively correlated with the fracture area ratio. Vowels / a /, / i /, / o /, / e /, / u / before and after the respective F1, F2, F3 were no significant differences. Conclusion The larger the fracture area ratio, the worse the patient’s unhealthy pronunciation habit. In the treatment, attention should be paid to correct bad pronunciation habit formed over the years so as to achieve better speech improvement effect.
