Teach more students with real-time captions. ESL learners, deaf students, and viewers with attention difficulties all benefit when your live lesson has accurate subtitles.
Start Free TrialOnline education has exploded. Universities, tutors, corporate trainers, and independent educators now reach students across the globe through YouTube Live, Twitch, and Zoom-style streaming platforms. But a live stream without captions excludes a significant portion of your potential audience.
Research from the National Deaf Center shows that over 48 million Americans have some degree of hearing loss. Beyond that, ESL (English as a Second Language) students consistently report that captions significantly improve their comprehension — captions let them read while listening, reinforcing vocabulary and grammar in real time. Studies from Oregon State University found that 66% of students reported captions helped them focus, and 75% said captions helped them understand the material better.
For educational content, captions aren't just an accessibility feature — they're a pedagogical tool that improves learning outcomes for everyone in your class.
If you're an institution, university, or corporate training program streaming educational content, WCAG 2.1 Success Criterion 1.2.4 requires synchronized captions for all live audio-only and synchronized media. This applies to public-facing streams and many internal corporate platforms. Section 508 compliance in the United States imposes similar requirements for federal agencies and their contractors.
StreamTranslate helps you meet these requirements with sub-500ms latency captions. The captions appear as an OBS Browser Source overlay — visible to every viewer watching your stream, on any platform, without requiring viewers to enable anything on their end.
ESL students following along in a second language, deaf and hard-of-hearing learners, students with ADHD who benefit from multimodal input, viewers watching in noisy environments (libraries, cafes), and anyone reviewing the stream VOD later at faster playback speeds.
StreamTranslate uses Deepgram's Nova-2 speech recognition engine — the most accurate STT model available for spoken English and 50+ other languages. Nova-2 is trained on large vocabularies and handles technical terminology, accents, and subject-specific jargon better than generic STT engines. For educators teaching chemistry, programming, law, or medicine, this matters enormously.
The setup takes about 3 minutes. You go to streamtranslate.live/setup, get your unique browser source URL, add it as a Browser Source in OBS Studio, size it to fit your stream layout, and start teaching. The captions appear automatically whenever you speak, with under 500 milliseconds of delay.
Sign up at streamtranslate.live and start your free trial. No credit card required immediately.
From the setup page, copy your unique caption overlay URL. This is the URL you'll paste into OBS.
In OBS Studio, add a new Browser Source, paste your URL, set width to your stream resolution. The caption box will appear in your scene.
Go live. Every word you speak appears as captions on-screen within 500ms. Students see captions automatically — no viewer-side setup required.
Teaching chemistry to a class that spans Brazil, Japan, Germany, and Nigeria? StreamTranslate can translate your spoken English into 50+ languages in real time. You speak English; students see captions in Spanish, Portuguese, Japanese, German, French, Arabic, or any of the other supported languages — simultaneously.
This transforms your English-language course into a genuinely international one without requiring you to learn another language or hire translators. At $9.99 per month after the free trial, it's a fraction of what a human interpreter costs for a single session.
For educational streams, caption readability is paramount. You want large, high-contrast text that doesn't obscure your slides or whiteboard. StreamTranslate's captions are fully customizable — you can position the caption box at the bottom of the screen, adjust the font size, and configure how many lines show at once.
Best practice for educational streams: position captions below any slides or diagrams, use a dark semi-transparent background behind the text, and keep font size at least 24pt for viewers on smaller screens. If you're teaching complex visual material, consider a split layout with captions at the very bottom of the frame.
StreamTranslate works on every major streaming platform. Whether you're teaching on YouTube Live, streaming lectures on Twitch, conducting corporate training via Facebook Live, or running webinars on any platform that accepts an OBS stream, the setup is identical. The browser source method works with OBS Studio, Streamlabs, vMix, and XSplit.
StreamTranslate is an OBS overlay — it works with any platform you stream to via OBS. If you're using OBS Virtual Camera to output your stream into Zoom or Meet, StreamTranslate captions will appear in that video feed.
