正常青年人基频及嗓音参数结果分析

目的：掌握正常青年人的嗓音数据,为病理嗓音提供参考标准。方法：收集 １５３ 例正常青年人的嗓音资料,用 Ｄｒ． Ｓｐｅｅｃｈ 嗓音及语言分析、训练系统软件,对取得的数据进行统计学分析。结果：结果示频率微扰（０．１８±０．０７）％ 、振幅微扰（１．６０±０．７４）％ 、谐噪比（２５．３４±３．１２）ｄ Ｂ、信噪比（２５．３９±３．０９）ｄ Ｂ、声门噪声能量（－ １６．９５±３．５７）ｄ Ｂ。男性基频平均值（１６０．８１±２４．２７） Ｈｚ、女性（２９７．４２±３５．８９） Ｈｚ、总平均值（２０６．３５±７０．７７） Ｈｚ。结论：嗓音的基频,男女间有极显著性差异（ Ｐ ＜ ０．０１）。男性分别在基频的４．５倍、８．６４倍、１７．０４倍处产生三个共振峰,女性在２．０７倍、４．９６倍、７．２８倍处产生三个共振峰。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

Analysis of results of fundamental frequency and voice parameter in healthy young people

OBJECTIVE: To study and analyzing the parameter values of voice in normal healthy young people. METHOD: In present paper, voice quality of 153 cases were collected and analyzed with Dr. Speech software. RESULT: 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. Average of fundamental frequency in male was (160.81 +/- 24.27) Hz, in female was (297.42 +/- 35.89) Hz and in all was (206.35 +/- 70.77) Hz. At the same time, the results of some correlative parameter about voice was taken. CONCLUSION: We considered that there were significant differences between gender about fundamental frequency in parameter values of voice. Three formant produced at 4.5 times, 8.64 times, 17.04 times of the fundamental frequency in male, at 2.07 times, 4.96 times, 7.28 times in female. This data was usefulness to evaluate voice results of normal or abnormal.
