Abstract

L'invention concerne un procédé et un dispositif de commande vocale. Le procédé consiste à : faire déterminer par un terminal commandé, lors de la réception d'une instruction de commande vocale, si l'instruction de commande vocale reçue correspond au terminal commandé (S20); et lorsque l'instruction de commande vocale reçue ne correspond pas au terminal commandé, faire diffuser l'instruction de commande vocale par le terminal commandé afin que d'autres terminaux commandés puissent détecter et recevoir l'instruction de commande vocale, ou faire déterminer, par le terminal commandé, d'autres terminaux commandés correspondant à l'instruction de commande vocale et faire en sorte qu'il transmette de façon correspondante l'instruction de commande vocale aux autres terminaux commandés déterminés afin que ceux-ci répondent à l'instruction de commande vocale (S30). Dans le protocole, lorsqu'un utilisateur envoie un signal de commande vocale, une instruction de commande vocale peut être transmise à un terminal commandé cible au moyen d'autres terminaux commandés se situant à proximité de l'utilisateur, afin de télécommander les terminaux commandés; ce protocole présente une précision de commande élevée, rend superflu l'aménagement spécial d'un terminal vocal pour commander les terminaux commandés, de sorte que les coûts sont réduits.
