Abstract:

Currently, speech recognition not yet optimized, it still has difficulties, in particular when it comes to the recognition in the Arabic language. This complexity is due to the ambiguities contained in the speech signal, and the various obstacles encountered during the processing of the signal. Indeed, a comparative study of extraction methods (LPC, MFCC, PLP, and RASTA) is made, and a review of existing combinations is carried out, to assess the rate of recognition of authentication systems. Our goal is reserved to develop an extractor’s recombination using the HMM classifier, with the aim of reaching a full treatment with a considerable amount of extracted vectors acoustic, in order to improvement the recognition rate of Arabic numerals.
