为客观评价激光辅助悬雍垂腭成形术(LAUP)对语音有无影响,利用USSA计算机语图频谱分析系统,对15名LAUP手术患者,进行了手术前.后2～3周/a/、/i/、/e/、/u/、/(?)/汉语单元音五个共振峰模式、基频和舌根软腭辅音/g/、/k/、/h/三维语图强频区频率的比较.结果显示;各元音前三个共振峰频率及基频在手术前后的变化无统计学意义,术后三个辅音的强频区频率改变也不明显,说明LAUP手术对汉语单元音的音质无影响,也不影响辅音的发音, To evaluate whether speech-assisted laser uvulopalatoproplasty (LAUP) has an effect on speech objectively, 15 LAUP patients underwent preoperative and postoperative 2 to 3 weeks / a / / i /, / e /, / u /, / (?) / Chinese phonetic five formant modes, fundamental frequency and tongue base soft palate consonants / g /, / k /, / h / The results showed that there was no significant difference in the frequency and fundamental frequency of the first three formant before and after the operation, and no significant change in the frequency of the strong frequency in the three consonants after the operation, indicating that the LAUF The sound quality has no effect, does not affect the pronunciation of consonants,
