Document Type and Number:
WIPO Patent Application WO/2019/196305
Kind Code:
A1
Abstract:
The present application relates to an electronic device, an identity verification method, and a storage medium. The method comprises: when a user performs transactions in an IVR scenario, broadcasting a random code of a first preset number of bits for the user to read, and upon reading, establishing acoustic models of preset types for the broadcasted random code and the voice read out by the user, respectively; performing a forced overall alignment operation on the acoustic model of the broadcasted random code and the acoustic model of the voice read out by the user, and using a predetermined algorithm to calculate the probability that the two aligned acoustic models are the same; if the probability is greater than a preset first threshold, extracting a voiceprint feature vector of the voice read out by the user, acquiring a standard voiceprint feature vector of the user pre-stored after successful registration, and calculating the distance between the voiceprint feature vector of the voice read out by the user and that standard voiceprint feature vector, so as to perform identity verification on the user. The present application performs dual verification on the identity of a user, and can accurately determine the identity of the user.
