| Abstract: | 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. |
