A natural language interface control system (206) for operating a plurality of devices (114) consists of a first microphone array (108), a feature extraction module (202) coupled to the first microphone array, and a speech recognition module (204) coupled to the feature extraction module, wherein the speech recognition module utilizes hidden Markov models. The system also comprises a natural language interface module (222) coupled to the speech recognition module (204) and a device interface (210) coupled to the natural language interface module (222), wherein the natural language interface module is for operating a plurality of devices coupled to the device interface based upon non-prompted, open-ended natural language requests from a user.

Ce système de commande d'interface en langage naturel (206) permettant d'exploiter plusieurs dispositifs (114), comporte un premier réseau de microphones (108), un module d'extraction des caractéristiques (202) couplé au réseau de microphones et un module de reconnaissance vocale (204) couplé au module d'extraction des caractéristiques. Le module de reconnaissance vocale utilise des modèles de Markov cachés. Le système comporte également un module d'interface en langage naturel (222) couplé au module de reconnaissance vocale (204) et une interface de dispositif (210) couplée au module d'interface en langage naturel (222). Ce dernier sert à l'exploitation de plusieurs dispositifs couplés à l'interface de dispositif en fonction de demandes en langage naturel non guidées et ouvertes émises par un utilisateur.
