Remove erroneous audio clips to obtain audio to be corrected.

Step S30: Acquire the re-recorded audio segment, and determine the target audio segment from the re-recorded audio segment.

It can be understood that the re-recorded audio segment is the re-recorded audio segment input by the user, which corresponds to the length of the deleted erroneous audio segment, and the target audio segment can be determined from the re-recorded audio segment as the subsequent audio segment Fragments, the re-recorded audio clips can be collected by direct on-site collection through a microphone, or directly imported into audio files that have been recorded and generated, where the audio formats include but are not limited to mp3, cd, ogg, and the like.

Step S40, judging whether the starting and ending points of the target audio segment are consistent with the positioning starting and ending points.

It should be understood that the start and end points of the target audio segment are the start and stop points of the target audio segment, that is, the time length of the target audio segment. By comparing the start and end points of the target audio segment with the Whether the positioning start and end points are consistent can determine whether the target audio segment matches the to-be-corrected audio and whether it can be seamlessly connected, so as to prepare for subsequent audio connection processing.
