Abstract

The invention is applicable to the field of Internet technology and provides a method and device for recognizing the voiceprint. The method includes the steps of establishing and training a universalrecognition model which is used for representing the distribution of voice features under a preset communication medium; obtaining voice data under the preset communication medium; constructing a corresponding voiceprint vector according to the voice data; and determining a voiceprint feature corresponding to the voiceprint vector according to the universal recognition model. According to the invention, the voice data are processed by constructing and training the universal recognition model to obtain the corresponding voiceprint vector so as to determine the voiceprint feature and recognize the voice-emitting person according to the voiceprint feature; and since the universal recognition model does not limit the content of the voice, the voiceprint recognition can be more flexibly used and the using scenes of the voiceprint recognition are increased.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a method and equipment for recognizing voiceprints. Background technique [0002] In the prior art, when the voiceprint feature is extracted during the voiceprint recognition process, the accuracy rate is not high. In order to achieve the accuracy of voiceprint recognition as much as possible, the user is often required to read the specified content, such as reading "one, two, three ", etc., and perform voiceprint recognition on the specified content. This method can improve the accuracy of voiceprint recognition to a certain extent. However, this method has relatively large limitations, because the user must read the specified content to complete the recognition. , so the usage scenarios of voiceprint recognition are limited. For example, when evidence collection is required, the other party cannot be asked to read the specified content aloud. [0003] For the ...
