实验结果表明：正常肺音音源为白噪声，异常肺音音源为周期脉冲序列，肺胸系统相当于声低通滤波器。
The results of experiment show that dreath sound sources are random white noise, Abnormal breath sounds sources are sequence of periodic impulses.
研究含有高斯白噪声的周期脉冲信号，通过阈值系统后的随机共振特性。
It is investigated that the characteristics of stochastic resonance of the periodic pulse signal added Gaussian white noise through a threshold system.
最后，通过使用残差激励代替周期脉冲—随机噪声二元激励，让合成语音的质量得到了一定的提升。
Finally, by using residuals instead of periodic pulse excitation - random noise binary excitation, s the quality of synthesized speech has been some upgrading.
