语音信号中噪音干扰的数字滤波技术

Digital filtering technique of processing noise in voice signal

分析了几种语音处理技术特征,针对语音信号处理过程中随机噪音干扰信号的特点,应用自适应干扰对消原理消除噪音,可使带有噪音的原始语言信号得到明显改善.理论分析及实验结果表明,数字滤波技术可方便地通过软件控制品质因数与带宽,因而可在通信、语言声学等领域广泛应用.

This paper expounds several voice processor techniques. As regards irregular noise interference in processing voice signal,this paper offers a new method to eliminate it by applying the theory of adaptive interference cancelling, and the voice signal with noise is improved obviously. It shows the importance of adaptive filter technique in the fields of processing the noise. 
