Abstract

The invention provides a voiceprint authentication processing method and apparatus. The method comprises steps of extracting the first characteristic vector of each voice in a training set by using a gender-mixing deep neural network (DNN) voiceprint baseline system; training a gender classifier according to the first characteristic vector of each voice and pre-marked gender labels; training DNN models of different genders according to the voice data of different genders in the training set; and training unified background models, characteristic vector extraction model, and probability linear discriminant analysis models of different genders according to the DNN models of different genders and the voice data of different genders in the training set. The method and the apparatus establish a voiceprint authentication processing model capable of distinguishing genders in order to increase voiceprint authentication efficiency and accuracy.

Description

technical field [0001] The present application relates to the technical field of voiceprint authentication, in particular to a voiceprint authentication processing method and device. Background technique [0002] With the continuous advancement of technology, the application fields of voiceprint recognition (Voiceprint Recognition, VPR) technology are becoming more and more extensive. [0003] Voiceprint recognition can confirm whether a certain voice is spoken by a specified person, for example, checking in time and attendance, or the user's voice needs to be confirmed during bank transactions. Before voiceprint recognition, it is necessary to model the speaker's voiceprint, which is the so-called "training" or "learning" process. [0004] The current training process of voiceprint recognition is to train and recognize voiceprints through a general-purpose model, and the accuracy is not high. Contents of the invention [0005] This application aims to solve one of the t...
