基于麦克风阵列的语音增强研究
Speech Enhancement Research Based on Microphone Array
摘要
Abstract
When adaptive algorithm of the microphone anay uses iteration to obtain die optimal weight vector about beamfonning.tbe noise model estimation is a critical factor. It will have a direct impact on the performance of beamforming system. Analyse systematically the least-mean-square (LMS) adaptive speech enhancement algorithms,and propose a method using a minima controlled recursive averaging (MCRA) to estimate the noise in allusion to the defects of the blocking matrix. This method is applied to beamforming, and using Matlab software to simulate. Simulation results show that,LMS-MCRA adaptive has robust speech enhancement.关键词
