Title
(EN) USER AUTHENTICATION METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL D'AUTHENTIFICATION D'UTILISATEUR
Abstract
(EN)
A method and apparatus for authenticating a user based on an utterance input includes obtaining an input audio signal based on the utterance input of the user; obtaining, from the input audio signal, at least one audio signal of an utterance section and at least one audio signal of a non-utterance section; generating environment information indicating an environment in which the utterance input is received, based on the at least one audio signal of the non-utterance section; obtaining a result of a comparison between the generated environment information and registration environment information indicating an environment in which a registration utterance input corresponding to a previously registered registration audio signal corresponding to the user is received; adjusting an authentication criterion for authenticating the user based on the result of the comparison; and authenticating the user based on the adjusted authentication criterion and the input audio signal.
(FR)
L'invention concerne un procédé et un appareil destinés à authentifier un utilisateur en fonction d'une entrée d'énoncé comprenant l'obtention d'un signal audio d'entrée en fonction de l'entrée d'énoncé de l'utilisateur; l'obtention, à partir du signal audio d'entrée, d'au moins un signal audio d'une section d'énoncé et d'au moins un signal audio d'une section sans énoncé; la génération d'informations d'environnement indiquant un environnement dans lequel l'entrée d'énoncé est reçue, en fonction du ou des signaux audio de la section sans énoncé; l'obtention d'un résultat d'une comparaison entre les informations d'environnement générées et des informations d'environnement d'enregistrement indiquant un environnement dans lequel est reçue une entrée d'énoncé d'enregistrement correspondant à un signal audio d'enregistrement préalablement enregistré correspondant à l'utilisateur; l'ajustement d'un critère d'authentification permettant d'authentifier l'utilisateur en fonction du résultat de la comparaison; et l'authentification de l'utilisateur en fonction du critère d'authentification ajusté et du signal audio d'entrée.
