目的提高腭裂术后患者的汉语语音清晰度。方法对２０例患者进行系统语音训练，包括训练前后语音清晰度测试、吹气训练及序列语音训练（单音→音节→词组→短句→短文）。结果患者的语音清晰度从训练前的平均４８．１％提高到训练后的平均９７．１％，平均提高了４９％，经ｔ经验，具有极显著差异（Ｐ＜０．０００１）；小年龄组训练平均周期比大年龄组平均周期短，有显著性差异Ｐ＜０．０５）。结论语音训练能纠正腭裂术后患者的代偿性发音习惯，使语音清晰度提高到与正常人基本一致
Objective To improve the clarity of Chinese speech in postoperative patients with cleft palate. Methods Twenty patients underwent systematic speech training, including speech intelligibility test, inflatable training and sequence speech training (single tone → syllable → phrase → short sentence → essay). Results The patients' speech intelligibility increased from 48.1% before training to 97.1% after training, with an average increase of 49% .Through experience, there was a significant difference (P <0.0001) Group training average period shorter than the average age group, with a significant difference P <0.05). Conclusion Speech training can correct the compensatory pronunciation habit of postoperative patients with cleft palate and improve speech intelligibility to the same level as that of normal people
