Twitch Stream Translator hear the streamer in your language, while they're live.
DubTab translates Twitch live streams as they happen — an AI voice dubs the streamer just a few seconds behind, with live translated captions on screen. Japanese, Spanish, French, Korean — whatever language the streamer speaks, you hear them in yours. Open the stream on twitch.tv in Chrome; the streamer doesn't change a thing.
Free 15-minute trial · No credit card · Works on streams without CC
Watch it dub a real Twitch stream — live, as it happens.
Chat translators translate the chat. Nobody translates the streamer.
Twitch doesn't caption or translate what the streamer says. The CC button only shows up on channels where the streamer set captions up themselves — and even then, it's in the streamer's language.
The translation tools you've seen for Twitch translate what viewers type in chat. The streamer's voice — the part you actually came for — stays in a language you don't speak.
Past broadcasts disappear after days or weeks depending on the channel, and they have no captions either. "I'll catch the VOD later with subtitles" isn't a thing on Twitch.
An AI voice dubs the streamer in your language a few seconds behind the stream — you follow along as it happens, hands free.
No CC needed — DubTab listens to the stream's audio itself, in whatever language the streamer speaks.
Live bilingual captions show the original and the translation together, with chat still open — so you keep up with both.

Built for streams that don't wait
Live dubbing, seconds behind
The AI voice follows the streamer with just a few seconds' delay — a voice you listen to while you watch the game, not captions you have to read.
Auto catch-up
If the dub drifts behind — a slow connection, a stuttering stream — it catches back up and stays in sync with the live edge.
No CC needed
Most Twitch streams have no captions at all, and the few that do aren't translated. DubTab listens to the audio itself, so it doesn't care.
Live bilingual captions
Original and translation on screen together, updating as the streamer talks — with chat still in view.
Built for marathon streams
Eight-hour sessions, subathons, all-night tournaments — DubTab keeps going as long as the stream does. And when the stream goes quiet for a few minutes, a BRB screen or an intermission, it pauses on its own, so you're not paying to translate silence.
Any language in, yours out
The streamer can speak any of 60+ languages — you pick what you hear. The streamer changes nothing.
What people watch on Twitch with DubTab
Twitch is a person talking to you for hours — in their language. These are the streams where that language is the only thing in the way.
Japanese streamers & VTubers
Some of the most-watched channels on Twitch stream in Japanese — and so do thousands of small ones nobody clips or subtitles. Hear them in your language as they talk, not from fan translations days later.
Spanish-speaking streamers
Spanish is one of the biggest languages on Twitch — streamers from Spain and all across Latin America, and almost none of it captioned. Follow them in your language while they're live, not from a recap.
Just Chatting
The biggest category on Twitch is a streamer talking — stories, reactions, answering chat, for hours. Follow the whole conversation, not just what you can guess from the emotes.
Gaming & esports co-streams
Streamers and casters from any country, in your language — the calls, the commentary, the jokes with chat. Watch the co-stream that's actually good, not the one that happens to be in your language.
IRL & travel streams
Someone walking through a city, a market, a festival, talking the whole way. The stream is in their language — the place they're showing you doesn't have to be.
Getting raided somewhere new
Your streamer raids a channel you've never heard of, in a language you don't speak. Stay — DubTab dubs the new streamer just the same, whatever language they're speaking.
Doesn't Twitch caption streams?
Only if the streamer does it. Twitch has no automatic captions for live streams — the CC button appears only on channels where the streamer added captions themselves, in the language they chose, and nothing is ever translated. The one place Twitch does auto-caption is Clips. On a live stream, everything has to happen in real time — and that's exactly what DubTab does, on your side of the screen.
| What you're watching | What Twitch gives you | DubTab |
|---|---|---|
| Stream where the streamer set up CC | Captions in the streamer's language only — no translation | ✓ Real-time dub + captions, your language |
| Stream without CC (most of them) | Nothing | ✓ Works the same — it listens to the audio |
| The chat | Not translated by Twitch — add-ons that do only handle text | ✓ Adds the streamer's voice — the part chat tools can't give you |
| Clips | Auto captions on Clips, in the streamer's language (rolling out since May 2026) | ✓ Works — though a few seconds behind is a lot on a 30-second clip. The stream is where it shines |
| Past broadcast (VOD) | Kept for days or weeks depending on the channel — no captions unless the streamer embedded them | ✓ Works like a regular video — while it's still there |
Nothing is pre-made on a stream — and captions aren't Twitch's job.
On some platforms a video arrives with caption tracks and dubbed audio attached. On Twitch, captions are the streamer's job: they have to push them through their encoder or set up an Extension, and almost nobody does. No transcript, no file, no track — 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 channel.
A few seconds behind — and it stays there.
The dub runs a few seconds after the streamer: 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 streams people actually sit through.
Just Chatting marathons, tournament co-streams, IRL walks, a subathon on its third day — the streams that run for hours and where the streamer's voice is the whole point. Open the channel on twitch.tv, pick your language, and you're in the room.
