L'invention concerne un système de dialogue vocal dans le lequel on utilise un procédé de commande automatique d'appareils par dialogue vocal, en appliquant des procédés de sortie des informations vocales, de prétraitement des signaux vocaux et de reconnaissance de la parole, de traitement syntaxique-grammatical ultérieur ainsi que de commande du dialogue, de la séquence d'exécution et de l'interface. L'invention se caractérise en ce que: la structure de syntaxe et la structure de commande sont définies pendant le dialogue en temps réel; le prétraitement, la reconnaissance et la conduite du dialogue sont conçus pour fonctionner dans un environnement parasité; l'utilisateur n'a besoin d'aucune formation pour la reconnaissance des commandes générales; certains utilisateurs ont besoin d'une formation pour la reconnaissance des commandes spécifiques; l'entrée de commandes s'effectue en mode lié, le nombre de mots utilisés pour former la commande d'une entrée vocale étant variable; le traitement et le déroulement du dialogue vocal se font en temps réels; l'entrée et la sortie des informations vocales s'effectuent en mode mains libres.
