Summary:A method (20) for creating a language model from a task-independent corpus is provided. In one embodiment, a task dependent unified language model (140) is created. The unified language model (140) includes a plurality of context-free grammars (144) having non-terminals and a hybrid N-gram model (142) having at least some of the same non-terminals embedded therein. L'invention concerne un procédé (20) permettant de créer un modèle de langage à partir d'un corpus indépendant des tâches. Dans un mode de réalisation, on crée un modèle (140) de langage unifié dépendant des tâches. Ledit modèle (140) de langage unifié renferme une pluralité de grammaires (144) non contextuelles à non-terminaux et un modèle hybride (142) du type N-gram dont certains non-terminaux au moins sont identiques à ceux de la grammaire non contextuelle.
