Abstract

The invention provides a voice detection method and device, electronic equipment and a storage medium. The method comprises the steps: extracting multiple pieces of voice feature information from the to-be-detected voice; respectively inputting the voice feature information into a plurality of pre-trained voice source models, and determining a first matching degree between the to-be-detected voice and the source type of each voice source model; for each voice category model, determining a second matching degree between the to-be-detected voice and the category type corresponding to the voice category model based on the determined first matching degree; and based on the determined plurality of first matching degrees and the determined plurality of second matching degrees, determining a category type and a source type of the to-be-detected voice. Thus, voice detection is carried out by adopting the voice category model and the voice source model under the voice category model, voice authenticity and voice source detection is completed, the problem of detection result offset of an existing voice detection technology is solved, and the accuracy of the voice detection method is improved.

Description

technical field [0001] The present application relates to the technical field of voice detection, in particular to a voice detection method, device, electronic equipment and storage medium. Background technique [0002] Speech spoofing attack refers to the technology of forging the voice of a specific target to attack the speaker recognition system. In recent years, attacks on speaker recognition systems are mainly divided into four categories, namely, human voice imitation, recording playback, speech synthesis, and speech conversion, which greatly threatens the user's personal identity authentication and personal information security. Therefore, how to accurately recognize and detect the received speech has received widespread attention. [0003] Usually, in the existing voice detection methods, due to problems such as the voice collection method or the clarity of the sound quality, the detection results are shifted, and there are cases where the human voice is mistakenly ...
