Patent

CA 2577721

Techniques are disclosed for automatically generating structured documents based on speech, including identification of relevant concepts and their interpretation. In one embodiment, a structured document generator uses an integrated process to generate a structured textual document (such as a structured textual medical report) based on a spoken audio stream. The spoken audio stream may be recognized using a language model which includes a plurality of sub-models arranged in a hierarchical structure. Each of the sub- models may correspond to a concept that is expected to appear in the spoken audio stream. Different portions of the spoken audio stream may be recognized using different sub-models. The resulting structured textual document may have a hierarchical structure that corresponds to the hierarchical structure of the language sub-models that were used to generate the structured textual document.

L'invention concerne des techniques de production automatique de documents structurés à partir de la parole, y compris l'identification de concepts pertinents et leur interprétation. Selon une variante, on décrit un générateur de documents structurés qui utilise un processus intégré pour produire un document textuel structuré (du type rapport médical textuel structuré) sur la base d'un flux audio parlé, lequel peut être reconnu au moyen d'un modèle de langage comprenant plusieurs sous-modèles disposés selon une structure hiérarchique. Chaque sous-modèle peut correspondre . à un concept dont on attend qu'il apparaisse dans le flux audio parlé. Différentes parties de ce flux peuvent être reconnues au moyen de différents sous-modèles. Le document textuel résultant peut avoir une structure hiérarchique qui correspond à la structure hiérarchique des sous-modèles utilisés pour la production du document textuel.
