With interactive voice response service, there are many different ways of asking for the same thing. In this invention the service learns the way in which a user usually asks for certain services and modifies a user specific grammar accordingly. This has the effect of increasing the accuracy of the speech recognition by reducing the number of variants which are expected. The system works well as long as the user does not suddenly start to use new words. In an improved version, the user specific grammar is checked periodically and modified if the user has introduced new words.

Par un service interactif de réponse vocale, il existe différentes manières de demander la même chose. Dans cette invention, le service apprend la manière dont un utilisateur demande habituellement certains services et modifie en fonction une grammaire spécifique de l'utilisateur. Cela a pour effet d'accroître la précision de la reconnaissance vocale en réduisant le nombre de variants prévus. Le système fonctionne bien tant que l'utilisateur ne démarre pas brusquement en utilisant de nouveaux mots. Dans une version améliorée, la grammaire spécifique de l'utilisateur est vérifiée périodiquement et modifiée si l'utilisateur a introduit de nouveaux mots.
