How to Add Live Translation to OBS
Go to StreamTranslate
Visit streamtranslate.live/control. Select your speaking language and the language you want subtitles in.
Copy your overlay URL
Your control panel generates a unique browser source URL. Copy it — this is the link you'll add to OBS.
Add as Browser Source in OBS
In OBS Studio, click "+" under Sources → Browser Source. Paste the URL. Set width: 1920, height: 1080. Position it at the bottom of your scene.
Go live with real-time OBS translation
Start streaming. Translated subtitles appear on your stream in real time — under 500ms latency, no extra software needed.
Why Use StreamTranslate for OBS Translation?
OBS Studio doesn't have built-in live translation. Plugins like LocalVocal require GPU overhead and break on OBS updates. StreamTranslate is a cloud-based browser source — paste one URL into OBS and you're done.
- No plugin install — works as a browser source on any OBS version
- Zero GPU overhead — all processing happens in the cloud
- 30+ languages — Spanish, French, Japanese, Korean, Arabic, Hindi, and more
- Under 500ms latency — subtitles appear in real time as you speak
- Works with OBS, Streamlabs, XSplit — any streaming tool with browser source support
- Dual language output — show original + translated text simultaneously on Pro plan
OBS Translation vs OBS Plugins
Most OBS caption and translation plugins (LocalVocal, Whisper, etc.) require local AI models that consume GPU memory and CPU cycles. They break when OBS updates. StreamTranslate works differently — it's a browser source URL, not a plugin. No configuration, no GPU, no breakage.
- LocalVocal: requires OBS plugin install, GPU overhead, breaks on updates
- StreamTranslate: browser source URL, cloud-based, never breaks, zero setup
