Abstract

The invention provides a voiceprint identity recognition method and device and electronic equipment. The voiceprint identity recognition method comprises the steps of acquiring frequency spectrum features of a voiceprint to be recognized; and identifying the frequency spectrum features through a voiceprint identification model to obtain identity information corresponding to the voiceprint to be recognized and attribute information of the voiceprint to be recognized. The voiceprint identification model is obtained by training the InfoGAN network in advance, the data volume of the required training sample is small, and after the frequency spectrum features are identified through the voiceprint identification model, an object identifier corresponding to the voiceprint to be regonized can be obtained, the age of the object corresponding to the voiceprint to be recognized, and the noise information and volume information of the voiceprint to be recognized can be obtained, so that the anti-time-varying capability and anti-noise capability of the model are improved, and the technical problems that an existing voiceprint identity recognition model does not have the anti-time-varying capability, the anti-noise capability is poor, and the number of samples required during training is large are solved.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to a voiceprint identification method, device and electronic equipment. Background technique [0002] The voiceprint identity authentication method is generally to perform identity authentication by training a voiceprint identity recognition model, using the output of the last layer of the model as the voiceprint feature, and calculating the similarity score of two voiceprint features. If the similarity score is higher than the threshold, they are considered to be the same person; otherwise, they are considered not to be the same person. That is, the voiceprint identification technology is the foundation and key of the voiceprint identification technology. [0003] The voiceprint identification technology has developed from the traditional i-vector technology to the current d-vector technology, and has achieved remarkable results. The deep learning technology involved in d-...
