摘要

采集到的语音信号中夹杂着大量的噪声，受环境、设备、语音清晰度等因素的影响，会严重影响信号的处理和分析。基于小波包和重排分布的降噪方案对语音信号的白噪声进行了提升。仿真结果表明，该方案有效地降低了语音信号的白噪声，在低信噪比下获得了满意的信号频谱。

An improved denoising method for speech signal

Collected the speech signal that mixed with large quantity noise will seriously influence the signal processing and analysis with affected of environment, equipment and voice clarity and so on. Based on wavelet packet and rearrangement distribution of de-noising scheme is raised to the white noise of the speech signal. Simulation results show that this scheme effectively reduce the white noise of the speech signal and obtain satisfied signal spectrum in low SNR.
