In this paper, the authors present an approach to the recognition of speech signal using frequency spectral information with Mel frequency for the improvement of speech feature representation in a HMM based recognition approach. The Mel frequency approach exploits the frequency observation for speech signal in a given resolution which results in resolution feature overlapping resulting in recognition limit. Resolution decomposition with frequency mapping approach for a HMM based speech recognition system. The simulation results show an improvement in the quality metrics of speech recognition w.r.t. to computational time, learning accuracy for a speech recognition system.
