A voiceprint identity identity identification method, device and computer-readable storage medium

Abstract

The present invention provides a voiceprint identification identity identification method, device and computer-readable storage medium, the method comprising: acquiring each audio to be identified for identity verification; performing formant extraction on each audio to be identified to obtain The broadband voiceprint diagram of the formant direction of each audio to be identified, wherein the abscissa of the broadband voiceprint is the bandwidth, and the ordinate is the frequency; in the broadband voiceprint diagram, determine the characteristics between the corresponding formants of each audio to be identified parameter; determine whether the feature parameter is within the preset range, if yes, pass the identity verification, if not, fail the identity verification. In the present invention, by displaying the voiceprint information of the audio as a broadband voiceprint map in which the abscissa is the bandwidth and the ordinate is the frequency, the voiceprint characteristics of the audio can be displayed more intuitively, helping to quickly verify the characteristics of the voiceprint and identity identity , improve the efficiency of voiceprint identification.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a voiceprint identity identification method, device and computer-readable storage medium. Background technique [0002] Voiceprint identification, also known as voice identification, is a specialized technology for personal identification of spoken words. Through voiceprint identity identification, it is possible to accurately determine whether several pieces of audio are from the same person. Therefore, it can be applied to many scenarios , such as the identification of criminal suspects in justice. [0003] In the existing voiceprint identification, the abscissa of the conventional two-dimensional spectrogram (voiceprint broadband map) is time, the ordinate is frequency, and the color depth of the coordinate points indicates the sound intensity, which is difficult to quantify. Voiceprint features such as peak trends are not intuitive enough, and a lot of lab...
