The invention discloses a voiceprint recognition method and device, electronic equipment and a storage medium. Relates to the field of artificial intelligence. According to the method, a plurality of voiceprint feature vectors are extracted from an initial audio data set by using a voiceprint recognition network, and the voiceprint feature vectors are divided into at least one vector set according to whether the voiceprint feature vectors are from the same person or not; and data screening is performed on the initial audio data set according to the similarity between each voiceprint feature vector in the vector set and the mean vector of the vector set, so that more accurate speaker annotation data can be obtained by controlling the similarity. When voiceprint recognition is carried out on a user, voiceprint features can be extracted by using a voiceprint recognition model obtained by training a target audio data set subjected to data screening. The target audio data set screened by the data screening method is accurate speaker annotation data, so that the identity of the user can be recognized more accurately when the voiceprint feature data of the user is recognized by using the voiceprint recognition model trained by the target audio data set.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular, to a voiceprint recognition method, device, electronic device and storage medium. Background technique [0002] Voiceprint recognition is an important direction of user identification, which has excellent characteristics such as uniqueness, short-term invariance, no loss, no forgetting, difficult to counterfeit, and non-contact; voiceprint recognition technology is becoming more and more mature, and more and more applications In access control, finance, social security, automobiles, home appliances, public safety and other fields. Voiceprint recognition training often relies on a large amount of accurate speaker annotation data, and it is difficult to obtain accurate speaker annotation data from the data pulled online. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present application proposes a voiceprint recognition method, d...
