Abstract

The invention discloses a voiceprint characteristic collection method and device and equipment. The method comprises the steps of acquiring voice data of a user, generating a spectrogram from the acquired voice data, extracting universality characteristics of the acquired voice data according to the spectrogram, restoring field voice of the voice data corresponding to the universality characteristics according to the universality characteristics, and extracting voiceprint characteristics of the field voice. By means of the mode, the accuracy of the obtained voice data of the user can be improved, and then the accuracy of the voiceprint characteristics extracted from the voice data can be improved.

Description

technical field [0001] The present invention relates to the field of voiceprint technology, in particular to a method, device and equipment for collecting voiceprint features. Background technique [0002] A voiceprint is a sound wave spectrum that carries speech information displayed by an electroacoustic instrument. Modern scientific research shows that voiceprint is not only specific, but also relatively stable. After adulthood, the human voice can remain relatively stable for a long time. Experiments have proved that the voiceprint of each person is different, whether the speaker deliberately imitates the voice and tone of others, or whispers softly, even if the imitation is vivid, the voiceprint is always different. [0003] The existing collection scheme of voiceprint features is generally to obtain the voice data of the user, and complete the collection of the voiceprint features of the voice data by extracting the voiceprint features from the acquired voice data. ...
