Abstract

The embodiment of the invention provides an accompaniment and human voice extraction method and device, a word-by-word lyric generation method and device, a storage medium and electronic equipment, and relates to the technical field of audio processing. The accompaniment and human voice extraction method comprises the following steps: acquiring mixed audio data in a time domain; encoding the mixedaudio data through an encoding module in an accompaniment voice extraction model to obtain encoded audio features; performing first convolution processing on the encoded audio features through a first decoding module in the accompaniment human voice extraction model to obtain target human voice audio data; enabling the encoding module and the first decoding module to form a first U-net network; performing second convolution processing on the encoded audio features through a second decoding module in the accompaniment voice extraction model to obtain target accompaniment audio data; and enabling the encoding module and the second decoding module to form a second U-net network. According to the invention, the accompaniment and human voice extraction effect can be improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of audio processing, and more specifically, relate to an accompaniment and vocal extraction method and device, a verbatim lyrics generation method and device, a storage medium, and an electronic device. Background technique [0002] This section is intended to provide a background or context for implementations of the disclosure that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Music source separation technology is one of the technologies that have been widely studied in recent years. Accompaniment and vocal extraction refers to the extraction of human voice audio and accompaniment audio other than human voice audio in mixed music audio. The accompaniment audio can be used In karaoke systems, music retrieval systems, etc., human voice audio can be used in scenarios such as pitch generation and emotional anal...
