ELECTRONIC DEVICE, IDENTITY VERIFICATION METHOD AND COMPUTER-READABLE STORAGE MEDIUM

WIPO Patent Application WO/2019/179029

A1

An electronic device, an identity verification method and a storage medium, wherein the method comprises: when receiving current voice data of a target user of which the identity is to be verified, acquiring standard voice data corresponding to the identity to be verified, and performing framing processing on the two pieces of standard voice data to obtain a current voice frame group and a standard voice frame group (S10); using a pre-set filter to respectively extract a pre-set type of acoustic feature of each voice frame of the two voice frame groups (S20); respectively inputting the extracted pre-set type of acoustic feature into a pre-trained deep neural network model of a pre-set structure to obtain a feature vector of a pre-set length respectively corresponding to current voice data and standard voice data (S30); and calculating cosine similarity between the two feature vectors, and determining an identity verification result according to the magnitude of the calculated cosine similarity (S40). The accuracy of identity verification of a speaker can be improved.
