A method for accelerating neural network execution (4) in a speech recognition system, specifically for recognition of words contained in one or more subsets of a general vocabulary, involves the following steps. - at the recognition system initialisation phase, calculating the union of vocabulary subsets and determining the acoustic-phonetic units required for recognising the words contained in that union; re-compacting the neural network eliminating all the weighted connections afferent to computation output units corresponding to unnecessary acoustic-phonetic units; - executing only the re-compacted network at each instant of time.
Procédé permettant d'accélérer l'exécution (4) de réseaux neuronaux dans un système de reconnaissance vocale, spécifiquement pour la reconnaissance de mots contenus dans un ou plusieurs sous-ensembles d'un vocabulaire général. Ledit procédé consiste à calculer, à la phase d'initialisation du système de reconnaissance, l'union de sous-ensembles de vocabulaire et à déterminer les unités acoustiques-phonétiques requises pour la reconnaissance de mots contenus dans cette union, à recomprimer le réseau neuronal en éliminant toutes les connexions pondérées afférentes aux unités de sortie de calcul correspondant à des unités acoustiques-phonétiques inutiles et à exécuter uniquement le réseau recomprimé à chaque instant.
