Live Stream Translator hear the streamer in your language, live.
DubTab translates live streams while they happen — on YouTube, Twitch, TikTok, Kick or any stream you open in Chrome on your computer. An AI voice dubs the streamer a few seconds behind, with live 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
Watch it dub a real Twitch stream from Spanish into English — as it happens.
Works on the streams you already watch
Pick your platform for the details — or open any live stream in Chrome and turn DubTab on.
And other live streams in your browser
X, Instagram Live, Weverse, SOOP, CHZZK, Bilibili Live, Douyin and more. DubTab listens to whatever the tab is playing, so it doesn't need the platform's help.
Watching in an app instead?
Discord, Zoom webinars and other desktop apps don't play in Chrome. The DubTab desktop app for Windows and Mac translates one app, or everything your computer plays.
Translate a live stream in 3 clicks
1. Add DubTab to Chrome
One click from the Chrome Web Store — the free trial is included. It works in Edge too.
2. Open the stream
YouTube, Twitch, TikTok, Kick or anywhere else — join it the way you always do.
3. Turn on dub & captions
Pick your language once. The AI voice starts within seconds and stays with the stream.
Made for how live streams work
Nothing is prepared in advance
A recorded video can come with caption tracks or dubbed audio. A live stream has none, so DubTab listens to the audio itself — in any of the 60+ languages the streamer might speak.
A few seconds behind — and it stays there
DubTab has to hear a phrase before it can say it in your language. Auto catch-up keeps the voice with the live edge instead of letting it drift further behind.
Missed a line? Scroll back
Not every stream lets you rewind — and rewinding takes you out of the live moment. You can reread it instead: the Caption Panel keeps what was said, and Follow Voice takes you back to the live line.
Built for streams that run for hours
Leave it on for the whole stream. When it goes quiet — a BRB screen, an intermission — DubTab pauses on its own after a few minutes, so silence doesn't use up your time.
Watch closely, or just listen
Captions on the video, a caption panel beside it, or Audio Only while the stream plays in the background — switch whenever you like.
Keep the stream's own sound
The dub plays over the original audio, which stays underneath at a lower volume — or dips only while the voice speaks, if you prefer. You set the balance: crowd noise, music and game sound stay in the room.
Who translates live streams with DubTab
The streams where waiting for a translated replay means missing them.
Japanese streamers & VTubers
Gaming streams and VTubers who stream in Japanese, dubbed into English as they talk — the jokes land while chat is still reacting.
K-pop fans on idol lives
When idols go live on Weverse or Instagram, hear what they're saying in your language — not from fan-translated clips hours later.
Spanish & Portuguese streamers
Just Chatting, IRL and gaming streams in Spanish or Portuguese, in English — without piecing it together from chat.
Esports & tournaments
Official broadcasts often run in just a few languages. Follow the casters in yours, live.
Launches & keynotes
Big announcements stream in one language first. Hear them as they happen, not in tomorrow's recap.
Live classes & trading rooms
Live lessons, market sessions and Q&As in online communities — follow along while you can still ask.
What else can translate a live stream?
A few things — and each covers part of it. Here's what you get from each, and where DubTab fits.
| Option | What it gives you | DubTab |
|---|---|---|
| The platform's own captions | Some streams, usually only in the streamer's language | ✓ Any stream — dub + captions in your language |
| Chrome's Live Caption & Live Translate | Translated captions — text only, no voice | ✓ A translated voice + captions, bilingual if you like |
| Chat translator extensions | Translate the chat, not the streamer | ✓ Translates what the streamer says |
| Translation apps on your phone | Work on your phone — mostly as captions | Not on phones — Chrome, Edge or the desktop app on a computer |
| Waiting for a translated replay | Only if someone makes one — after it ends | ✓ While it's live, a few seconds behind |
Read it, hear it, or both.
Captions let you read along; a voice lets you keep your eyes on the stream. If translated captions are all you need, Chrome's own Live Translate may already be enough. DubTab adds the voice — the dub and live captions at once, bilingual if you like — and you decide how much of each.
Every platform does live captions its own way.
Some caption a few streams in one language, some leave it to the streamer, some have only just started — and it keeps changing. The platform pages go through YouTube, Twitch, TikTok and Kick one by one.
Nothing for the streamer to do.
Everything runs on your side. The streamer doesn't add captions or change a setting, and doesn't need to know you're listening in another language — which is why it works on streams nobody set up for translation.
