YouTube Live Translator hear every stream in your language — live.
DubTab translates YouTube live streams while they happen — an AI voice dubs the speaker just a few seconds behind, with live translated captions on screen. The streamer doesn't have to set up a thing.
Free 15-minute trial · No credit card · Works on streams without captions
Live means now — not after someone translates it.
YouTube's automatic live captions are English-only, and only some streams have them — there's no translation at all.
A stream doesn't pause while you look something up — by the time you've caught one sentence, three more are gone.
Waiting for the replay with subtitles means missing the launch, the match, the Q&A — the part that made it live.
An AI voice dubs the speaker in your language a few seconds behind the stream — you follow it as it happens.
No captions needed — DubTab listens to the stream's audio itself, in any language it's spoken in.
Live bilingual captions let you follow the original and the translation together, chat open, in the moment.

Pick your language once. The AI voice starts within seconds and stays with the stream.
Built for streams that don't wait
Live dubbing, seconds behind
The AI voice follows the speaker with just a few seconds' delay — not a translation you get after the stream ends.
Auto catch-up
If the dub drifts behind — a slow connection, a buffering stream — it catches back up and stays in sync with the live edge.
No captions needed
Most live streams have no usable captions at all. DubTab listens to the audio itself, so it doesn't care.
Live bilingual captions
Original and translation on screen together, updating as the speaker talks.
Built for long streams
Launch events, all-day conferences, live classes — DubTab keeps going as long as the stream does.
Any language in, yours out
The stream can be in any of 60+ languages — you pick what you hear, the streamer changes nothing.
What people watch live with DubTab

Doesn't YouTube caption live streams?
Only some of them, only in English, and never translated. And auto-dubbing doesn't apply to live at all — it's generated when a video is uploaded, which a live stream never is. On a stream, everything has to happen in real time; that's exactly what DubTab does, on your side of the screen.
| The stream you're watching | What YouTube gives you | DubTab |
|---|---|---|
| English stream with auto captions on | English captions only — no translation | ✓ Real-time dub + captions, your language |
| Stream in any other language | No automatic captions at all | ✓ Works the same — it listens to the audio |
| Low-latency stream, or captions not enabled | Auto captions unavailable | ✓ Works the same — it listens to the audio |
| Any live stream, dubbed audio | Auto-dubbing doesn't apply to live | ✓ Real-time AI dub, a few seconds behind |
Nothing is pre-made on a live stream.
A regular video can arrive with caption tracks and dubbed audio attached. A live stream has none of that — no file, no tracks, nothing generated ahead of time, and auto-dubbing never applies. Whatever you get has to be produced while the stream runs. DubTab produces it on your side: live dub and captions, in your language, for any stream.
A few seconds behind — and it stays there.
The dub runs a few seconds after the speaker: DubTab has to hear a phrase before it can say it in your language. What matters on a long stream is that the gap doesn't grow — auto catch-up keeps the voice pinned to the live edge instead of drifting minutes behind.
Made for the events people watch live.
Product launches, sports, live classes, creator streams, conference keynotes — the moments where waiting for a translated replay misses the point. Open the stream, pick your language, and you're in the room.
