摘　　要：目的　本文收集青年人正常及病理的嗓音资料 ,对其参数进行统计分析 ,掌握正常人的嗓音参数的正常值 ,并对病理嗓音结果进行对比性分析。方法　用Dr .Speech嗓音及语言分析、训练系统软件 ,采集 148例正常人及 4 37例病人嗓音资料 ,对取得的数据进行对比分析。结果　正常人频率微扰 0 .18± 0 .0 7%、振幅微扰 1.60± 0 .74 %、谐噪比 2 5.34±3.12dB、信噪比 2 5.39± 3.0 9dB、声门噪声能量 - 16.95± 3.57dB。男性基频平均值 160 .81±2 4 .2 7Hz、女性基频平均值 2 97.4 2± 35.89Hz、基频总平均值 2 0 6.35± 70 .77Hz。病理嗓音患者上述结果有不同程度的改变。结论　病理嗓音的结果示声带小结、声带息肉、声音嘶哑及单侧声带麻痹患者嗓音主要参数均有异常改变并以基频微扰、声门噪声能量最为敏感 ;男性声带麻痹 (单侧、双侧 )及男腔女调患者平均基频、最大基频、最小基频、习惯基频、基频方差均有明显提高。这些数据的取得 ,对我们评价正常及病理嗓音结果有一定的参考价值。Objective To compare normal voice parameters and voice disorder cases. Methods The voice data of 148 healthy people and 437 vocal cord disorder patients were collected with Dr.Speech 3.0 v software. The data were compared and analyzed. Results Jitter was 0.18 ± 0.07 (%),Shimmer 1.60 ± 0.74 (%), HNR (Harmonics-to-Noise Ratio) 25.34 ± 3.12 dB, SNR(Signal-to-Noise Ratio) 25.39 ± 3.09 dB and NNE(Normalized Noise Energy) -16.95 ± 3.57 dB. The average fundamental frequency was 160.81 ± 24.27 Hz, 297.42 ± 35.89 Hz in females and 206.35±70.77Hz in all. In the voice disorder cases, the above parameters were changed in different degrees. The main voice parameters were changed in vocal nodules, polyp of the vocal cord, unilateral recurrent laryngeal nerve paralysis. The fundamental frequency, max frequency, min frequency, mode frequency, and SD of the fundamental frequency were increased significantly in recurrent laryngeal nerve paralysis (unilateral, bilateral) cases and gynecophonus cases. Conclusion The data are useful in the evaluation of voice results of normal or abnormal people.
