<p>The subject of the invention is a voice recognition procedure which comprises: (a) a step of decomposition of a digitised voice signal into a plurality of fractions, (b) a step of representation of each of the fractions by means of a representative vector Xt, (c) a step of classification of the representative vectors Xt, which comprises two or more multistep binary tree residual vectorial quantisations. In the classification step a phonetic representation is associated to each representative vector Xt, allowing a sequence of phonetic representations to be obtained. <IMAGE></p> |
