FILTER BANK AND ITS APLLICATION TO SPEECH PROCESSING

The model. design technique, examples and application of the reconfigurable tunable. nonuniform frequency spaced filter bank are presented in this paper. The bank is build based on polyphase decomposition and all­ pass transformation technique. Analysis of the polyphase structure reveals a significant computational reduction in exchange for an increase in warping algorithm complexity and control. The proposed filter bank can be used in systems for speech and audio processing where the auditory model is used as a analysis and synthesis tool.
