A six-band filter structure derived by using admissible wavelet
packets for the extraction of the features for recognition of noisy
speech is proposed. A simple compensation for white Gaussian noise is
carried out and the recognition performance is compared with the
features based on Mel scale cepstral coefficients (MFCC) and 24-band
admissible wavelet packet filter structure
