Title (EN) SEARCH METHOD BASED ON SINGLE TRIPHONE TREE FOR LARGE VOCABULARY CONTINUOUS SPEECH RECOGNIZER
(FR) PROCEDE DE RECHERCHE FAISANT APPEL A UN ARBRE SIMPLE TRIPHONE UTILISE AVEC UN LOGICIEL DE RECONNAISSANCE VOCALE EN CONTINU A VOCABULAIRE ETENDU
Abstract: front page image
(EN)A search method based on a single triphone tree for large vocabulary continuous speech recognizer is disclosed in which speech signal are received. Tokens are propagated in a phonetic tree to integrate a language model to recognize the received speech signals. By propagating tokens, which are preserved in tree nodes and record the path history, a single triphone tree can be used in a one pass searching process thereby reducing speech recognition processing time and system resource use.
(FR)L'invention porte sur un procédé de recherche faisant appel à un arbre triphone simple utilisé avec un logiciel de reconnaissance vocale en continu à vocabulaire étendu. Ce procédé consiste à envoyer des signaux vocaux; des unités lexicales sont diffusées dans un arbre phonétique de manière à s'intégrer dans un modèle linguistique afin de permettre la reconnaissance des signaux vocaux reçus. Grâce à la propagation des entités lexicales, contenues dans les noeuds d'arbre et enregistrant l'historique du chemin parcouru, il suffit d'utiliser un seul arbre triphone pour effectuer une recherche simple, ce qui réduit la durée de traitement dans le cadre de la reconnaissance vocale ainsi que l'utilisation des ressources du système.
