Research on voiceprint identity recognition and verification technology and its application in mobile payment

This paper studies an identity recognition and verification system based on the DTW voiceprint recognition algorithm. The system hardware is composed of a TC264 single-chip control chip, and the MCP6022 microphone module is used as a sensor. Through AD conversion, the input voice is converted into an arithmetic matrix, and the MEL frequency is used. Cepstral coefficient and MFCC algorithm perform spectrum analysis on the voiceprints of different people, upload them to the data cloud to form a voiceprint database, and finally complete the synchronous transmission of the data through communication with the mobile phone software platform, and complete the identification and verification of the identity on the mobile phone.
