单麦克风和双麦克风语音增强系统的研究，这是基础的双麦克风降噪算法，但是很实用-Single microphone and dual-microphone speech enhancement system, which is based dual-microphone noise reduction algorithm, but very practical

joint sparse representation (JSR)方法用于车内语音增强的特征降噪算法-address reducing the mismatch between training and testing conditions for hands-free in-car speech recognition. It is well known that the distortions caused by background noise, channel effec
