Abstract

The present application discloses a voiceprint recognition method, device, device and storage medium, wherein the method includes: acquiring a speech to be recognized; extracting a first spectrogram of the speech to be recognized; inputting the first spectrogram to a preset limited Feature extraction is performed in the Boltzmann machine; the extracted features are input into the preset SVM classifier to obtain the recognition result of the speech to be recognized. This application uses a preset restricted Boltzmann machine to extract the features of the first spectrogram of the extracted sample speech, and input the extracted features into the preset SVM classifier for classification and recognition, which solves the existing voiceprint problem. The recognition method recognizes by manually comparing the spectrum graphs, and there are technical problems of low recognition efficiency and low accuracy.

Description

technical field [0001] The present application relates to the technical field of voiceprint recognition, and in particular to a voiceprint recognition method, device, equipment and storage medium. Background technique [0002] Voiceprint recognition refers to the process of making a conclusion whether the two are the same by comprehensively analyzing and comparing the speech acoustic features of an unknown or uncertain speaker with those of a known speaker. The existing voiceprint recognition method usually manually compares the spectrogram of the sample speech with the spectrogram of the sample speech to obtain the voiceprint recognition result. This method has the problems of low efficiency and low recognition accuracy. Contents of the invention [0003] The present application provides a voiceprint recognition method, device, equipment and storage medium, which are used to solve the technical problems of low recognition efficiency and low accuracy in the existing voicep...
