Abstract
According to this process, a speech signal is analyzed in a vector quantizer (1) in which the acoustic parameters are calculated for each interval of time of a predetermined value and are compared with each spectral reference template contained in a reference template dictionary (2) utilizing a distance calculation. The sequence obtained at the output of the vector quantizer (1) is then compared with each of the words stored in a word lexicon (5) in a phonetic form utilizing phonetic distribution tables (3) associated with each template. A particular word of the speech to be recognized is then recognized as corresponding to a word stored in the lexicon having the maximum probability of its constituent phonetic units according to the phonetic distribution tables.
