Live Subtitles on a Big Screen
Put the speaker's words on a projector or LED wall as they talk, with the translation right behind them. For trade show stages, keynotes, panels and booth demos.

In a loud hall, many people cannot hear the speaker clearly, and a mixed audience may not share the speaker's language. Captions on the big screen help both groups at once, and everyone in the room sees the same words.
How it works
The presenter, or the sound desk, opens the Subtitles screen on a laptop or tablet and starts recording. Captions of the speaker's own words appear as they speak, and each translated sentence follows a few seconds later.
Show that screen on a projector or LED wall, or press Copy OBS URL to get a link for a transparent subtitle source. Paste the link into OBS, or open it on a second computer connected to the screen. Keep the Subtitles page open and recording on the presenter's device.
Where it fits
Anywhere one speaker addresses a room.
- Stage talks and keynotes at trade shows and conferences
- Product demos at a booth with a screen behind the presenter
- Panels, launches and press briefings
- Livestreams that need a caption layer over the video, through OBS
Captions on phones too
Some listeners would rather read in their own language on their own phone. The same session shows a QR code. Visitors scan it, pick a language and read along in their browser. No app and no account.
What you need
A laptop or tablet with a microphone near the speaker, a screen or projector, and a reliable internet connection. The Subtitles screen can show up to 5 languages side by side. Every account starts with 1 free hour each month, so you can run a real test first.

Can the subtitles show on a projector or an LED wall?
Yes. Show the Subtitles screen on the display, or open the Copy OBS URL link on the computer that drives it.
Can I put the captions over a livestream?
Yes. The Copy OBS URL link is a transparent subtitle source you can add to OBS as a Browser Source.
How fast do the captions appear?
The speaker's own words appear as they speak, and each translated sentence follows a few seconds later. A faster mode that shows translations almost as the sentence ends is in testing.
What helps the captions come out well?
Place the microphone close to the speaker, ask them to pace themselves and pause between points, and send the product names to the speaker ahead of the talk.
Is it enough for a high stakes session?
It is a tool, not a person. For legal proceedings or any session where one wrong word could cause harm, keep a human interpreter alongside it.
