Real-time translation for Bilibili videos and live rooms

How to set it up

1. 1
   Open Tingdong and pick “Live Listen”

   Choose “Screen sound” so it captions exactly what the page plays, including a live room.

2. 2
   Press Play

   Captions float over the video: the original line on top, your language below, updating while the sentence is still being spoken.

3. 3
   Optional: have the translation spoken

   For long tutorials or a live room running in the background, the translation can be read aloud in your language.

Burned-in subtitles and danmaku both leave you without text to translate

Two things on Bilibili look like subtitles and are not. Danmaku is viewer comments scrolling across the picture — useful, but it is a chat feed, not what the speaker said. Burned-in subtitles are part of the image, so no tool can select, extract or auto-translate them the way it would a subtitle file. That leaves the audio as the only reliable source of the actual words, which is exactly what Tingdong uses: it captions the spoken track, so an uploaded video, a live room, a tutorial, a documentary and a recorded stream all behave the same. Language is detected per phrase among 60+ inputs, so a video that mixes Mandarin with English technical terms keeps captioning without a setting change.
