摘要:
在采集语音时常常不可避免地混入背景噪声, 使语音质量下降, 从而影响了语音处理中各种算法的效果。因此研究语音消噪系统是非常必要的。该文分析了多通道语音增强系统, 提出一种采用两级滤波器的消噪系统。计算机模拟结果表明,其消噪性能明显优于Zelinski 法[ 1] , 听音试验也证实了这一点。
Abstract:
T he speech receiv ed under many circumstances is o ften disturbed by vario us noises. T his ser io usly decr eases the intellig ibility and ar ticulat ion o f the received speech. Therefo re, it is essent ial to use some method to ex t ract the clean speech. In this paper , w e pr opo se a new alg orithm w ith tw o stag e Wiener f ilter to suppr ess noise, both its SNR and the intelligibility of the f il tered speech are bet ter than those of Zelinski’s method.
