| Abstract: | Three enhancement algorithms are introduced based on wavelet domain(i.e.,enhancement algorithm of reconstruction from modulus maxima,spatial correlation enhancement algorithm and wavelet threshold enhancement algorithm),and then the advantages and disadvantages are compared respectively.The denoising simulation is carried out to the noisy speech signal with the above enhancement algorithms.The results show that wavelet threshold enhancement algorithm has more excellent effects than the others on speech enha... |
