Claim:
1. A computer implemented system for identifying significant speech frames within speech signals for facilitating speech recognition, said system comprising: a memory configured to store instructions and data; a processor configured to receive said instructions and data from said memory; an input module configured to accept at least an input speech signal, wherein the speech signal is represented by a plurality of feature vectors; a spectrum analyzer cooperating with said input module to receive the input speech signal, said spectrum analyzer comprises a divider configured to divide the input speech signal into a plurality of speech frames, said spectrum analyzer further configured to compute a spectral magnitude of each of the speech frames; an extractor cooperating with said spectrum analyzer to receive said speech frames, and configured to extract at least a feature vector from each of the speech frames; a suitability engine, of said computer, cooperating with the spectrum analyzer to receive the spectral magnitude of each of the speech frames and configured to compute a suitability measure for said speech frames, said suitability engine of said computer comprises: a frame weight assigner, of said computer, cooperating with the spectrum analyzer to receive the spectral magnitude of each of said speech frames and the final suitability measure module provided in the suitability engine, of said computer, to receive the final suitability measure of each of said speech frames, and configured to compute weight for each of said speech frames to identify significant speech frames based on the spectral magnitude and the final suitability measure of respective speech frame.
