Embodiment 1

[0026] A method for rapid voiceprint verification based on application scenarios, applied to electronic equipment, the steps are as follows figure 1 shown:

[0027] (1) After obtaining the application scenario, determine the voiceprint judgment threshold based on the application scenario;

[0028] (2) acquiring the voice to be verified and inputting the voice to be verified into a probability linear discriminative analysis classifier, and the probability linear discriminative analysis classifier outputs a voiceprint score;

[0029] (3) judging whether the voiceprint score obtained in step (2) is greater than or equal to the voiceprint judgment threshold determined in step (1), if so, the voiceprint verification passes, otherwise the voiceprint verification fails;

[0030] The training process of the probabilistic linear discriminative analysis classifier is to take the voice with known identity as the input, the voiceprint score of the voice as the theoretical output, and the...

Embodiment 2

[0034] An electronic device comprising one or more processors, one or more memories, one or more programs, and a voice collection device for acquiring the voice to be verified;

[0035] One or more programs are stored in the memory, and when the one or more programs are executed by the processor, make the electronic device execute the same method for fast voiceprint verification based on an application scenario as in Embodiment 1.

Abstract

The invention discloses a voiceprint rapid verification method based on application scenes and application thereof. The method comprises the steps: determining a voiceprint judgment threshold based on an application scene after obtaining the application scene; acquiring a to-be-verified voice, inputting the to-be-verified voice into a probability linear discrimination analysis classifier, and outputting a voiceprint score by the probability linear discrimination analysis classifier; and judging whether the voiceprint score is greater than or equal to a voiceprint judgment threshold, if so, passing voiceprint verification, and otherwise, not passing voiceprint verification. The training process of the probability linear discrimination analysis classifier is a process of continuously adjusting parameters by taking the voice with known identity as input and taking the voiceprint score of the voice as theoretical output. According to the method, different threshold values are set for different application scenes, the problem that the data processing amount is too large is solved, verification data are improved, user experience is improved, and the method has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of voiceprint verification, and relates to a method for rapid voiceprint verification based on application scenarios and applications thereof, in particular to a method for setting voiceprint scores based on different application scenarios to complete voiceprint rapid verification and its application . Background technique [0002] In recent years, with the continuous advancement of technology, online services have become more and more everyday in people's lives. Online services in banking, securities, insurance and other industries have been continuously launched. Due to the need for security, in recent years, the securities industry has begun to implement appropriate investor policies. Sexual management measures, the measures require the full implementation of double recording in the industry. Double recording is mainly to keep a record of the process of customer handling business, especially the process ...
