摘　　要：介绍了一种基于近距离放置的双传声器波束形成和双通道能量差掩蔽相结合的语音增强算法。该算法简单,适合在DSP上实时实现,对特定方向上的语音具有很好的增强效果,能够应用于多种噪声环境。实验表明,即使在信噪比较低的情况下,该算法也有良好的表现。A speech enhancement algorithm based on the beamforming and the interaural intensity difference using two closely spaced microphones is proposed. The algorithm is simple. It can be realized on the DSP easily. The algorithm can get a better performance at the special directions. It can also work in many kinds of noisy environments. According to the experi- ments, the algorithm still has a good performance when the SNR is low.
