• 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。
• The deficiency of this algorithm is due to only use a simple time-invariant threshold. It means that the time-invariant wavelet thresholding not only suppresses background noise but also some speech components like unvoiced parts.
  这种算法的缺点是所使用的简单的时不变的阈值不仅会消除背景噪声，也会消除语音信号中的有用的清音成分。
