Add real-time captions and 125+ language translation to your NVIDIA Broadcast streams. StreamTranslate integrates via browser source — no plugins, no complicated routing, no technical expertise required.
Get Started FreeStreamTranslate integrates with NVIDIA Broadcast using the browser source feature that most streaming software supports natively. A browser source renders a web page directly inside your streaming scene, allowing StreamTranslate to display live captions as a transparent overlay on top of your game, camera, or other content.
The setup process takes under 60 seconds: create a free StreamTranslate account at streamtranslate.live, copy your unique browser source URL from the dashboard, open NVIDIA Broadcast and add a new browser source to your scene, paste the URL, set the dimensions to 1920x1080, and drag the source to the top of your layer stack. StreamTranslate will immediately begin capturing your microphone audio and displaying live captions.
StreamTranslate uses Deepgram Nova-2, the most accurate real-time speech recognition engine available, to transcribe your speech in under 300ms. Captions appear on screen almost as the words leave your mouth, keeping subtitles synchronized with your live content. For multilingual streams, StreamTranslate's NMT translation layer then converts captions into your chosen target language from 125+ supported languages.
Captions dramatically expand the audience that can engage with your content. Deaf and hard-of-hearing viewers — approximately 15% of the global population — can follow your stream with captions where they couldn't before. Non-native speakers of your language follow along better with text support, especially during fast speech or gaming vocabulary. Viewers watching in noisy environments or quiet spaces without headphones benefit from readable captions. Research shows captions increase average view duration by 40% and improve content retention across viewer demographics.
For global streamers, StreamTranslate's translation layer is a genuine growth channel. If you stream in English, Spanish-speaking viewers can receive real-time Spanish captions, Japanese viewers can see Japanese captions, and Portuguese-speaking viewers get Portuguese — all from a single StreamTranslate setup. With 125+ languages supported, StreamTranslate unlocks audience segments that were previously inaccessible without separate multilingual streaming setups.
StreamTranslate's captions are also significantly more accurate than platform-provided auto-captions because they use Deepgram Nova-2 rather than older ASR models. Custom vocabulary support lets you add game titles, character names, streamer handles, and community-specific terms to ensure they're transcribed correctly every time.
