研究了对局部平稳高斯色噪声混响模型和以局部平稳高斯色噪声混响模型为基础的分段匹配滤波和分段预白化匹配滤波检测算法。

Secondly, local stationary colored reverberation model and the block matched filtering and block prewhiten matched filtering detection methods which based on the model is studied.

目前国内外声混响消减方法很多，如复倒谱法、逆滤波法、波束形成等。

So far, many kinds of dereverberation methods have been developed, such as complex cepstrum filtering, inverse filtering, beam forming and so on.
