Abstract: This paper presents a new speech enhancement method. This method based on wavelet filters via multistage convolution with Reverse Biorthogonal Wavelets (RBW) in the high and low pass band frequency parts of the speech signal. In this method a speech signal is decomposed into two parts; a high-pass and a low-pass, the noise is then removed in each band individually in different stages via wavelet filters. The proposed method provides good results where it does not cut the speech information, which occurs when utilizing conventional thresholding. The proposed method is tested and the objective evaluation is used to compare the results with the other used methods. The new proposed method shows superiority over Donoho and Johnstone thresholding method and Birge-Massart thresholding strategy method.
