Problems solved by technology

[0003] At present, for the display of audio and video subtitles, generally for pre-recorded audio and video, manually add subtitle text according to the content of the speaker in the audio and video, and directly display the subtitle text on the screen of the audio and video; in addition, considering the audio and video subtitles When the subtitles are displayed, only one or two lines of subtitle text are displayed on one screen, and the amount of information transmitted is small. For live broadcast or situations where users cannot watch the speakers repeatedly, such as in the conference scene, each participant is in the When listening to the speaker's speech, the subtitles are displayed on the screen in real time. If the user does not understand a certain sentence of the speaker, he cannot re-view the subtitle text on the spot. Obviously, this display method cannot meet the application requirements.
