| Abstract: | This paper introduces the application of wavelet transformation in speech signal denoising, describes in detail the method of soft threshold and hard threshold and points out their disadvantages. In view of these the method of soft hard compromise denoising algorithm has been put forward and the superiority of the algorithm has been proved with experiment. |
| Keywords: | wavelet transformation speech signal denoising soft threshold method hard threshold method soft and hard compromise method |
