Abstract

The embodiments of the application provide a human voice extraction method. The method comprises the steps of performing vocal extraction on mixed audio based on a human voice extraction model to obtain intermediate audio, wherein the intermediate audio comprises a human voice audio frame and a non-human voice audio frame; filtering out the non-human voice audio frame in the intermediate audio based on a human voice filtering model to obtain human voice audio. After the human voice extraction method is adopted, the pure human voice audio can be extracted, so that the user experience is improved.

Description

technical field [0001] This application relates to the field of electronic audio signal processing, in particular to a human voice extraction method, a human voice extraction device and related products. Background technique [0002] Human voice extraction technology is a widely studied audio processing method, and there are many categories of existing human voice extraction algorithms. However, due to the limitations of the algorithm itself or the training samples, there is currently no vocal extraction algorithm that can cleanly extract the human voice. For example, in the prior art, the human voice is extracted from the mixed audio through the Hourglass model. Although the extracted human voice result is relatively clean and has a high degree of recognizability, some instrumental performances such as preludes and interludes are misidentified as human beings. Errors that are reserved for sound. Therefore, it is impossible to extract completely pure human voice from mixed...
