- W2361686982 abstract "Threshold de-noising technology for speech signal based wavelet analysis is an important topic in speech signal processing. Due to the nonstationarity of speech signals,traditional Wavelet Threshold De-noising Algorithm could attenuate part of the noise in speech signal. However,this algorithm would inevitably cause the loss of the useful speech signal. By using wavelet packet the speech signal could be decomposed into the low frequency part and the high frequency part,thus the speech information could be better,kept while the influence of noise be eliminated. And a new threshold function is proposed,which could de-noise the speech signal more completely. Simulation results show that,this proposed function,as compared to the hard or soft threshold function,is of obvious superiority." @default.
