Title:
METHOD AND DEVICE FOR TRAINING VOICEPRINT RECOGNITION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024259
Kind Code:
A1
Abstract:
A method and device for training a voiceprint recognition system and related to the field of voiceprint recognition technology. The method comprises: obtaining a voice training set (101); respectively determining identity vectors of voice segments in the voice training set (102); determining, from the determined identity vectors, identity vectors of multiple voice segments of a same user, for respective users (103); classifying the identity vectors of the same user identified from among multiple users into a user category from among multiple user categories (104); determining any one of the identity vectors in the user category to be a first identity vector (105); regularizing the first identity vector by means of a regular matrix (106); and training the regular matrix, and outputting a regular matrix training value when the regular matrix causes the sum of first values of each user category to be maximized (107). The method resolves the issue of a limited increase in the accuracy of voiceprint recognition employing identity vectors processed by linear discriminant analysis, enhancing the accuracy of voiceprint recognition.
