Abstract

A new filter structure using admissible wavelet packet analysis is presented, These filters have the advantage of having frequency bands spacing similar to the Mel scale, Further wavelet packet transform's multiresolution capabilities are used to derive new sets of features, which are found to be superior to Mel frequency cepstral coefficients (MFCC) in unvoiced phoneme classification problem.
