And it searches much further for the unvoiced frame according to the ZCR ( zero crossing rate), which is differ from unvoiced frame to background frame.

To prevent the quality degradation of the unvoiced sounds during the denoising process, we first separate unvoiced regions from noisy speech and then apply the thresholding method to them in a different way from other regions.

同时，为了防止在抑制噪声的过程中对语音的清音段信息造成损失，首先对语音信号进行了清浊音判别，然后针对不同的判别结果对清音段语音和浊音段语音采用不同的阈值处理方法。

On the other side, the character of CELP algorithm is that it does not distinguish voiced or unvoiced speech, and it uniformly uses time domain waveform matching method based on AbS principle to produce LP excitation, which is represented by vector codes.

CELP算法的主要特点是不区分语音信号的清浊音类型，而是统一使用基于AbS原理的时域波形匹配方法来产生线性预测激励，且该激励信号通过矢量码本来表示。

In this paper, multi-parameters ( short-time energy, short-time zero-crossing rate and autocorrelation function values) combination has been adopted to judge the unvoiced/ voiced of speech signal. Then circular average magnitude difference function has been used to calculate pitch.

采用基于多参数组合方法（短时能量、短时过零率、自相关函数值）进行语音信号清浊音判别，利用循环平均幅度差函数进行基音周期计算。
