Start Translating Free → No credit card · 49 languages · Works with OBS, Streamlabs, XSplitStreamTranslate listens to your microphone, transcribes your English speech, and translates it into Spanish as you talk. Viewers see readable Spanish subtitles on the stream instead of a separate translation app or delayed transcript.
The overlay works on Twitch, YouTube Live, Kick, and TikTok because it runs as a standard browser source. Add your personal overlay URL to OBS, choose English as the spoken language and Spanish as the target language, then stream normally.
StreamTranslate 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 advanced AI speech recognition for fast, accurate transcription, then races multiple translation engines to return the best result in under 500ms. 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.
