Abstract

The invention discloses a method and a device for voiceprint registration and a method and a device for voiceprint authentication, wherein the method for voiceprint registration comprises the steps of: respectively extracting various types of voiceprint features corresponding to N registration corpora input by a user, wherein N is greater than 1; and fusing the various types of voiceprint features, and establishing a registration voiceprint model of the user. In the method, through fusing the various types of voiceprint features to establish the registration voiceprint model, reliability and accuracy of authenticating validity of the user through the registration voiceprint model are improved.

Description

technical field [0001] The invention relates to the technical field of voice processing, in particular to a voiceprint registration and authentication method and device. Background technique [0002] At present, in order to ensure the security of the user's personal information, etc., many applications first need to authenticate the legitimacy of the user. For example, when a user uses Baidu Tieba, Baidu Tieba can verify the legitimacy of the user according to the user name and password entered by the user. [0003] In related technologies, related applications only authenticate the legitimacy of the user based on the user name and password entered by the user, and cannot identify whether the authenticated user is the registered user himself. When others obtain the user name and password of the registered user, they can also be authenticated as legitimate users. , so as to obtain the user information of registered users, the security of user information cannot be guaranteed...
