基于传声器阵的两级自适应滤波语音增强系统

A two-stage adaptive voice enhancement system based on microphone array

基于自适应噪声对消思想,提出一种基于传声器阵的自适应语音增强结构,该结构经过两级自适应滤波,分离出增强语音信号。计算机仿真结果显示该系统能有效去除背景噪声。

A two-stage adaptive filtering algorithm is proposed for speech e nhancement based on mi-crophone array.The speech signal is extracted from the noisy signal after the final adaptive filtering due to the novel structure of t he microphone array.Simulation result shows that the system works ef-fectivel y even when the signal to noise ratio(SNR)is very low.
