Prise en compte de contraintes pragmatiques pour guider un système de reconnaissance de la parole : le système COMPPA

Abstract : In order to develop robust and efficient speech recognition system, the number of possible hypotheses corresponding to a spoken utterance has to be drastically reduced. In the specific framework of vocal command systems, this often leads to the design of languages that are difficult to learn. As a consequence, the use of these systems is limited to environment where neither keyboard, nor mouse can be used (chapter 1). Our purpose is then to take into account the application and dialogue context to define the accepted language dynamically. For example, the command "erase the green cube" will not be considered at first if there is no instance of a green cube in the application at the time the sentence is uttered. Similarly, the utterance "erase it" will be eliminated if the pronoun "it" is irrelevant in the current dialogue context. Constraining the recognition process by means of such pragmatic considerations allows us to accept a more natural language (chapter 2). [...]
