The invention provides a voiceprint identification method and device, a model training method and device, equipment and a storage medium, and relates to the technical field of voiceprint identification. The voiceprint identification method comprises the following steps of: acquiring to-be-identified voice data; carrying out feature extraction on the to-be-identified voice data and to-be-matched voice data in a voice database to obtain to-be-input features, wherein the to-be-input features comprise features of multiple preset dimensions; according to the to-be-input features and a preset voiceprint identification model, identifying and acquiring whether a target voice matched with the to-be-identified voice data exists in the voice database or not; and if so, determining that the to-be-identified voice data passes the identification. Compared with the prior art, the problem that the accuracy is not high enough due to the fact that the target voice is determined according to the single feature dimension or the voiceprint identification result is determined according to subjectivity is avoided.
Description
technical field [0001] The present application relates to the technical field of voiceprint identification, in particular, to a voiceprint identification method, a model training method, a device, a device, and a storage medium. Background technique [0002] Like DNA, fingerprints and other characteristics, voiceprint is a characteristic that everyone has. It can be used to identify identity and has great potential in criminal investigation, payment, security, password and other fields. [0003] In the voiceprint identification in the prior art, the features of the voice are generally extracted first, and then the identity judgment is made by comparing the similarity between the voice features of the test material and the voice features of the sample. The main theoretical basis of the current voiceprint identification technology is the Source-Filter Model (Source-Filter Model), in which the formant only reflects the characteristics of the vocal tract, that is, the acoustic c...
