CA 2454506

A language model (114) is created for speech recognition from a text database (122)by an offline modeling processing (130) (solid line arrows). In an online processing, when a user talks to request for search, an acoustic model (112) and the language model (114) are used to perform a speech recognition processing (110) and write-up is created. Next, by using the search request written up, a text search processing (120) is performed and the search result is output in the order of higher correlation.

L'invention concerne un modèle linguistique (114) établi pour la reconnaissance vocale à partir d'une base de données textuelle (122) par traitement de modélisation hors ligne (130) ( flèches en trait plein sur la figure). Dans un traitement en ligne, lorsque l'utilisateur (locuteur) intervient verbalement pour formuler une demande de recherche, on fait appel à un modèle acoustique (112) et au modèle linguistique susmentionné (114) afin d'engager un traitement en reconnaissance vocale (110), et un enregistrement de la demande est établi. Ensuite, sur la base de la demande enregistrée, un traitement de recherche textuelle (120) est engagé, et le résultat de la recherche est présenté selon l'ordre de corrélation le plus élevé.
