Speech Enhancement by Multi-Channel Crosstalk Resistant Adaptive Noise Cancellation

A novel multi-channel crosstalk resistant adaptive noise cancellation (MCRANC) algorithm is presented in this paper to enhance noise carrying speech signals. The algorithm would permit locating the microphones in close proximity as it cancels out the crosstalk effect. Results have indicated that this method outperforms the commonly used techniques in the sense of SNR improvement and speech intelligibility. A SNR improvement of 17.8 dB using MCRANC keeping highly intelligible speech was achieved in our experiments versus 9.1 dB using multi-channel ANC (MANC) with far less speech quality
