So speech denoising becomes increasingly important to improve voice quality in noisy environments.
因此为了提高噪声环境下语音的质量，噪声消除不足变得日益重要。
Filtering signal in the wavelet domain, by the frequency components acceptable for ear from the original speech, is a simple and effective speech denoising method.
利用此特性对信号进行小波域滤波，可从加噪的语音中提取人耳所能接受的频率成份，是一种简单有效的语音去噪算法。
A method of adaptive speech denoising based on orthogonal wavelet transform is proposed in this paper. This method can increase the convergence rate of the adaptive processing.
本文提出了一种基于正交小波变换的自适应语音消噪改进方法，这种方法可以提高自适应语音消噪过程的收敛速率。
