Problems solved by technology

Compared with the first solution, although its effect of removing crosstalk sound is better than that of the first solution, it is limited by hardware performance, and the maximum number of microphones that can be supported has been fixed at the factory, and the scalability is poor. , it is difficult to upgrade
[0006] To sum up, the solutions for removing crosstalk in the prior art have poor scalability, so it is difficult to upgrade

Abstract

The embodiment of the invention discloses a method, device, equipment and system for processing voice data and a medium and aims at enhancing the extendibility and reducing the upgrading difficulty while crosstalk voice are removed. The method comprises the steps that the correlation of each path of voice data and other paths of voice data and the signal-to-noise ratio of each path of voice data are determined in multiple paths of voice data obtained after time domain aligning treatment is carried out; the type of each path of voice data is determined according to the correlation of each pathof voice data and other paths of voice data and/or the signal-to-noise ratio of each path of voice data, wherein the type of the voice data comprises main voice and crosstalk voice; the voice data ofthe main voice type is kept, and the voice data of the crosstalk voice type is removed.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a voice data processing method, device, equipment, medium and system. Background technique [0002] In the application scenario of multiple microphones, when a speaker speaks, the microphone corresponding to the speaker will receive the sound, and the other microphones will also receive the sound. The part of the sound received by the other microphones belongs to the crosstalk sound. [0003] When processing voice data, it is necessary to remove crosstalk sounds. At present, there are mainly two solutions for removing crosstalk sounds: [0004] The first solution is to add an anti-crosstalk module in the front-end microphone. In this solution, the anti-crosstalk module is set in the microphone. When removing the crosstalk sound, it is removed based on the voice data of a single channel (or single microphone). The actual effect is not ideal, and an anti-cro...
