Noise Reduction from Speech Signal based on Wavelet Transform and Kullback-Leibler Divergence

A new method for speech enhancement based on Kullback-Leibler (K-L) divergence has been presented in this paper. First, the algorithm performs wavelet-packet transform to noisy speech and decomposes it into sub-bands; then we apply a threshold on coefficients in each sub-band to obtain enhanced spee...
