Title (EN) DEEP LEARNING-BASED VOICEPRINT AUTHENTICATION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF D'AUTHENTIFICATION D'EMPREINTE VOCALE BASÉE SUR L'APPRENTISSAGE EN PROFONDEUR

Abstract:
(EN) A deep learning-based voiceprint authentication method and device. The deep learning-based voiceprint authentication method comprises: receiving voice of a speaker (S11); extracting a d-vector feature of the voice (S12); obtaining a d-vector feature of the speaker determined at a registration stage (S13); calculating a matching value between the two d-vector features (S14); and determining that the speaker passes authentication if the matching value is greater than or equal to a threshold (S15). By means of the method, the voiceprint authentication effect can be improved.
(FR) La présente invention concerne un procédé et un dispositif d'authentification d'empreinte vocale basée sur l'apprentissage en profondeur. Le procédé d'authentification d'empreinte vocale basée sur l'apprentissage en profondeur consiste en : la réception de la voix d'un locuteur (S11); l'extraction d'une caractéristique de vecteur d de la voix (S12); l'obtention d'une caractéristique de vecteur d du locuteur déterminée à une étape d'enregistrement (S13); le calcul d'une valeur de correspondance entre les deux caractéristiques de vecteur d (S14); et la détermination que le locuteur réussit l'authentification si la valeur de correspondance est supérieure ou égale à un seuil (S15). Le procédé permet d'améliorer l'effet d'authentification de l'empreinte vocale.
(ZH) 一种基于深度学习的声纹认证方法和装置,该基于深度学习的声纹认证方法包括:接收说话人的语音(S11);提取所述语音的d-vector特征(S12);获取所述说话人在注册阶段确定的d-vector特征(S13);计算上述两个d-vector特征之间的匹配值(S14);如果所述匹配值大于或等于阈值,则确定所述说话人通过认证(S15)。该方法能够提高声纹认证的效果。
