Title: VOICEPRINT RECOGNITION-BASED IDENTITY VERIFICATION METHOD, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Abstract:
The present invention relates to a voiceprint recognition-based identity verification method, an electronic device, and a storage medium. The voiceprint recognition-based identity verification method comprises: after receiving voice data of a user performing identity verification, obtaining a voiceprint feature of the voice data, and building a corresponding voiceprint feature vector on the basis of the voiceprint feature; inputting the voiceprint feature vector into a background channel model generated by training in advance to build a current voiceprint identification vector corresponding to the voice data; and calculating a space distance between the current voiceprint identification vector and a pre-stored standard voiceprint identification vector of the user, performing identity verification on the user on the basis of the distance, and generating a verification result. The present invention can improve the accuracy and efficiency of user identity verification.
