Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0037] Since in many application scenarios, the duration of voiceprint data is relatively short, but accurate voiceprint recognition is required, so there is a lack of a voiceprint recognition model with high recognition accuracy for shorter voiceprint data. However, in the prior art, the accuracy of the voiceprint recognition models obtained by training the voiceprint data with a shorter duration is relatively low.
[0038] In order to solve the above problems, the embodi...

The invention provides a voiceprint recognition model training method, a voiceprint recognition method and related equipment, and the voiceprint recognition model training method comprises the steps: inputting first voiceprint data into a teacher network and a student network, and carrying out the Nth iteration training, wherein the teacher network is trained and converged according to second voiceprint data, and the duration of the second voiceprint data is longer than that of the first voiceprint data; calculating a first mean vector of a first feature vector output by the teacher network and a second feature vector output by the student network; and under the condition that an output value corresponding to the first mean vector satisfies a first preset condition, determining the to-be-trained model subjected to the Nth iteration training as a voiceprint recognition model, the voiceprint recognition model comprising a teacher network and a student network subjected to the Nth iteration training. Therefore, the accuracy of the voiceprint recognition model is improved.
Description
technical field [0001] The present application relates to the technical field of voiceprint recognition, in particular to a voiceprint recognition model training method, a voiceprint recognition method and related equipment. Background technique [0002] As a credible voiceprint feature authentication technology, voiceprint recognition has broad application prospects in many fields and scenarios such as identity authentication and security verification. However, speech is easily affected by various noise environments, emotions, physical conditions and other external environment and its own factors. Therefore, improving the accuracy of voiceprint recognition has extremely important practical significance. Currently, in the training process of the voiceprint recognition model, when the duration of the voiceprint data is short, the accuracy of the trained voiceprint recognition model is likely to be low.
