Abstract: A new speech enhancement method based on multitaper spectrum method and wavelet thresholding is proposed so that a noisy speech power spectrum is obtained. As for the faults of the hardthresholding and softthresholding, an improved model of threshold (the modulus squared mode1) is presented. During the noise estimation, the estimation of its spectrum is updated by tracking the speechabsent frames. The experimental results show that this method presented here can quickly track the changes of the speech and has better denoise function. When combining the method with speech enhancement, the enhancement result is better than that of STSA algorithm.

Key words: multitaper spectrum method, wavelet thresholding, noise estimation , speech enhancement
