| Abstract: | Based on the multiresolution analysis theory of the wavelet, the algorithm about using unbiased risk estimate is proposed to de-noise the noisy speech in this paper. The experimental results show that this algorithm has better de-noising ability in the speech signal of the low SNR(signal noise rate). |

| Keywords: | noisy speech wavelet transform de-noising unbiased risk thresholding |
