Start Translating Free → No credit card · 28+ languages · Works with OBS, Streamlabs, XSplitStreamTranslate is a cloud-based live subtitle and translation service built for streamers who want to reach a global audience. You speak in your native language and viewers see accurate translated subtitles on your stream in real time. Everything runs in the cloud, so there is zero CPU or GPU overhead on your streaming PC.
The system uses Deepgram's nova-2 speech recognition for fast, accurate transcription, then races multiple translation engines to return the best result in under 2 seconds. The translated text renders as a styled subtitle overlay via an OBS browser source — no plugins, no third-party software, and no browser extension on the viewer side.
Setup is simple: sign up at streamtranslate.live, pick your speaking language and your target subtitle language, copy your personal browser source URL, and paste it into OBS as a new Browser Source. Position it at the bottom of your scene and go live. Pro and Unlimited plans support dual-language output so you can serve two audiences at once.
