Abstract

L'invention concerne une technique de commande d'une interface vocale (I/F) pour faire fonctionner un appareil thermique par la voix. Ce dispositif de commande pour commander la voix I/F comprend : une entrée I/F pour recevoir un signal d'entrée de l'extérieur ; une unité arithmétique pour déterminer, lorsque le signal d'entrée est un signal vocal, si le signal vocal indique ou non un mot de fonctionnement préparé ; et une sortie I/F pour émettre un signal de commande à l'extérieur. Lors de la réception d'un signal d'entrée vocale à partir de l'entrée I/F et ayant déterminé que le signal indique un mot de fonctionnement prédéterminé, l'unité arithmétique sort par l'intermédiaire de la sortie I/F un signal de commande pour demander la confirmation de l'exécution d'une commande vocale correspondant au mot de fonctionnement prédéterminé. Lors de la réception d'un second signal d'entrée par l'intermédiaire de l'entrée I/F après la transmission du signal de commande et ayant déterminé que le second signal d'entrée est un signal de réponse de confirmation affirmant l'exécution de la commande vocale, l'unité arithmétique émet par l'intermédiaire de la sortie I/F un signal de commande pour ordonner l'exécution de la commande vocale.
