Abstract

The present invention is applicable to the field of Internet technology, and provides a method and device for recognizing voiceprints, the method comprising: establishing and training a general recognition model, the general recognition model is used to represent the distribution of speech features under a preset communication medium; obtaining Voice data under the preset communication medium; constructing the corresponding voiceprint vector according to the voice data; determining the voiceprint feature corresponding to the voiceprint vector according to the general recognition model. The present invention processes the voice data by constructing and training a universal recognition model to obtain the corresponding voiceprint vector, thereby determining the voiceprint features, and identifying the person who made the sound according to the voiceprint features. Since the universal recognition model does not limit the content of the voice, therefore This makes the use of voiceprint recognition more flexible and increases the usage scenarios of voiceprint recognition.

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 ...
