Abstract
The present disclosure describes techniques of synchronizing subtitles in live broadcast The disclosed techniques comprise obtaining a source signal and a simultaneous interpretation signal in a live broadcast; performing voice recognition on the simultaneous interpretation signal in real-time to obtain corresponding translation text; delaying the simultaneous interpretation signal to obtain a first delayed signal; delaying the source signal to obtain a second delayed signal; obtaining proofreading results of the first delayed signal and the corresponding translation text; determining proofread subtitles based on the proofreading results; and sending the proofread subtitles and the second delay signal to a live display interface.
