Problems solved by technology
[0004] When this method is verified, it only considers the influence of the model itself on the accuracy of voiceprint verification. There are other influencing factors in practical applications, such as differences in crowd distribution in different application scenarios. The influence of non-models on voiceprint recognition results in inaccurate verification results

Embodiment Construction
[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0053] The method, device, computer equipment and storage medium for verifying the recognition effect of the voiceprint model provided by this application can be applied to such as figure 1shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The application program of the terminal 102 supports voiceprint verification, collects the user's voice signal through the terminal, sends the voice signal to the server, and the server invokes the voiceprint model for identification and authentication. The server also ...

The invention relates to artificial intelligence, and particularly discloses a method and device for verifying the recognition effect of a voiceprint model, computer equipment and a storage medium. Voiceprint verification is carried out on each test user at least twice by calling the voiceprint model according to the registered audio and verification audio of each test user in a verification dataset to obtain a test recognition success rate. On one hand, the data source used for verifying the voiceprint model can reflect the crowd distribution of the service scene and can truly reflect the use condition of the actual service scene, and on the other hand, at least two times of login verification are carried out during login testing to meet the use willingness of a user. Therefore, the verification result of the voiceprint model recognition effect obtained by adopting the method can truly reflect the use effect of the actual service scene, the model effect deviation caused by non-modelfactors is eliminated, and the verification accuracy is improved.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a method, device, computer equipment and storage medium for verifying the recognition effect of a voiceprint model. Background technique [0002] Voiceprint has the advantages of easy acquisition and low identification cost, so the application of voiceprint recognition is becoming more and more extensive. Voiceprint recognition is to convert the acoustic signal into an electrical signal, and then use a computer to identify it. Specifically, a neural network is used to train a voiceprint model to recognize voices. The recognition effect of the voiceprint model has a decisive impact on the application of voiceprint. [0003] After the voiceprint model is trained, it is usually verified to evaluate whether it can be applied online. In the traditional solution, use pre-collected audio files, use 3 audios in each group as the voiceprint registration audio,...
