| Abstract: | 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. |

| Keywords: | Adaptive Noise Cancellation(ANC) microphone array speech enhancement adaptive filte ring LMS algorithm |
