Title
(EN) APPARATUS FOR NOISE CANCELING AND METHOD FOR THE SAME
(FR) APPAREIL DE SUPPRESSION DE BRUIT ET SON PROCÉDÉ
Abstract
(EN)
An embodiment of the present invention provides an apparatus for noise canceling that includes: an input unit configured to receive an input voice signal that is a target of noise canceling; and a processor configured to generate a first voice signal by canceling noise from the input voice signal on the basis of a noise canceling model which is trained using a plurality of reference voice signals through a deep learning algorithm, generate a second voice signal by canceling residual noise from the first voice signal on the basis of statistical analysis, and generate an output voice signal corresponding to the second voice signal.

La présente invention concerne, dans un mode de réalisation, un appareil de suppression de bruit qui comprend : une unité d'entrée configurée pour recevoir un signal vocal d'entrée qui est une cible de suppression de bruit ; et un processeur configuré pour générer un premier signal vocal par suppression de bruit à partir du signal vocal d'entrée sur la base d'un modèle de suppression de bruit qui est entraîné à l'aide d'une pluralité de signaux vocaux de référence par l'intermédiaire d'un algorithme d'apprentissage profond, générer un second signal vocal par suppression d'un bruit résiduel à partir du premier signal vocal sur la base d'une analyse statistique et générer un signal vocal de sortie correspondant au second signal vocal.
