Title (EN) METHOD FOR DRIVING A DIALOG SYSTEM
(FR) METHODE DE COMMANDE D'UN SYSTEME DE DIALOGUE
Abstract:
(EN) The invention describes a method for driving a dialog system (1) comprising an audio interface (11) for processing audio signals (3,6). The method deduces characteristics (2) of an expected audio input signal (3) and generates audio interface control parameters (4) according to these characteristics (2). The behaviour of the audio interface (11) is optimised based on the audio interface control parameters (4). Moreover the invention describes a dialog system (1) comprising an audio interface (11), a dialog control unit (12), a predictor module (13) for deducing characteristics (2) of an expected audio input signal (3), and an audio optimiser (14) for optimising the behaviour of the audio interface (11) by generating audio input control parameters (4) based on the characteristics (2).
(FR) L'invention concerne une méthode de commande d'un système (1) de dialogue qui comprend une interface audio (11) pour traiter des signaux audio (3, 6). La méthode déduit des caractéristiques (2) d'un signal d'entrée audio attendu (3) et génère des paramètres (4) de commande de l'interface audio en fonction de ces caractéristiques (2). Le comportement de l'interface audio (11) est optimisé sur la base des paramètres (4) de commande de l'interface audio. En outre, l'invention décrit un système (1) de dialogue qui comprend une interface audio (11), une unité (12) de commande du dialogue, un module de prédiction (13) pour déduire les caractéristiques (2) d'un signal d'entrée audio attendu (3) et un optimiseur audio (14) pour optimiser le comportement de l'interface audio (11) en générant des paramètres (4) de commande de l'entrée audio sur la base des caractéristiques (2).
