Title
(EN) VOICE-CONTROLLED MANAGEMENT OF USER PROFILES
(FR) GESTION DE PROFILS UTILISATEURS À COMMANDE VOCALE
Abstract
(EN)
A management of user profiles comprises calculating, for each speaker model of at least one speaker model, a confidence measure representing a probability that the speaker model represents a speaker of a cluster of audio segments. A user profile associated with the speaker model is updated based on a user preference assigned to the cluster of audio segments if the confidence measure calculated for the speaker model represents a probability that is higher than a target probability. The embodiments achieve an efficient user profile management in a voice-controlled context but without the need for any dedicated enrollment sessions to train speaker models.
(FR)
L'invention concerne une gestion de profils utilisateurs consistant à calculer, pour chaque modèle de locuteur d'au moins un modèle de locuteur, une mesure de confiance représentant une probabilité que le modèle de locuteur représente un locuteur d'une grappe de segments audio. Un profil utilisateur associé au modèle de locuteur est mis à jour d’après une préférence utilisateur attribuée à la grappe de segments audio si la mesure de confiance calculée pour le modèle de locuteur représente une probabilité qui est supérieure à une probabilité cible. Les modes de réalisation permettent d’obtenir une gestion de profils utilisateurs efficace dans un contexte à commande vocale sans nécessiter de sessions d'inscription dédiées pour apprendre des modèles de locuteurs.
