Abstract

The embodiment of the invention relates to a voiceprint recognition technology, and discloses a voice call noise elimination method, which comprises the following steps of: carrying out voice endpointdetection on a call audio to obtain a human voice set; performing voice feature extraction on the human voice set to obtain a voice feature set; intercepting a to-be-detected voice feature set of which the cumulative duration is a preset duration threshold from the voice feature set according to a time sequence to obtain a plurality of to-be-detected voice feature sets, performing clustering processing on each to-be-detected voice feature set, and scoring the clusters; and according to the score, dividing the human voice set into a first speaker voice and a second speaker voice, distinguishing a background human voice from the first speaker voice and the second speaker voice, and deleting the background human voice from the human voice set. The invention also relates to a blockchain technology, and the call audio can be stored in the blockchain. The background voice in the voice call can be deleted, so that the voice call quality is improved.

Description

technical field [0001] The present invention relates to the technical field of voiceprint recognition, in particular to a noise elimination method, device, electronic equipment and computer-readable storage medium for voice calls. Background technique [0002] Customer service systems, especially intelligent outbound call systems, often need to face the background noise interference of the customer's environment. Among all the noises, background human voices have the strongest noise interference. The automatic speech recognition of the intelligent outbound call system will also recognize background human voices and use them as the target of the dialogue, which greatly affects the success rate of the overall dialogue. [0003] However, the current noise elimination technology mainly eliminates non-human voice background noise, and the noise elimination effect on background human voice is poor, resulting in poor voice call quality. Contents of the invention [0004] The inv...
