Abstract:

Provided are a subtitle generation method and apparatus, and a device and a storage medium. The method comprises: when a subtitle generation trigger operation for at least one audio track in a target audio and video file is received, respectively performing speech recognition on audio data on each audio track in the at least one audio track, so as to obtain a text fragment corresponding to each audio track; and then, generating subtitles for the target audio and video file on the basis of the text fragment corresponding to each audio track. In comparison with performing overall speech recognition for audio data on all audio tracks, the embodiments of the present disclosure are aimed at respectively performing independent speech recognition on audio data on each audio track, such that audio tracks are prevented from affecting one another, and a more accurate speech recognition result can be obtained, thereby improving the accuracy of subtitles generated on the basis of the speech recognition result.
