Abstract

The invention relates to an audio editing method and apparatus, an electronic device and a storage medium. The method comprises steps of obtaining a modified text obtained by modifying an original text of a known to-be-edited audio according to a known modification text; predicting an audio duration corresponding to the modified text; adjusting a to-be-edited area of the to-be-edited audio according to the audio duration corresponding to the modified text to obtain an adjusted to-be-edited audio; on the basis of the pre-trained audio editing model, the edited audio being obtained according to the adjusted to-be-edited audio and the modified text, the edited audio obtained through the audio editing model is natural in context listening feeling, and the function of synthesizing new words not appearing in a corpus is supported.

Description

Technical field [0001] The present application relates to the field of speech processing, and more particularly to a method, apparatus, electronic device, and storage medium for editing audio. Background technique [0002] The rapid development of the Internet accelerates the spread of information. There are a variety of media for learning, entertainment and communication, such as movies, videos, interactive online education, etc. The production of these media is often inseparable from audio content editing. Typical audio content editing interface Displays voice visualization, such as waveforms, and / or spectral maps, and provides users with standard selection, shearing, copying, pasting, and volume adjustment, which are applied to the waveform itself, but also support some advanced operations, For time stretching, pitch bending and denoising. These tools provide great convenience for media producers and have a wide range of application scenarios. [0003] Some systems allow the...
