Real-Time Accessibility Captions
Make every word of your live stream accessible. Real-time captions delivered as an OBS browser source — readable, customizable, WCAG-aligned. 60-second setup.
Why "real-time" matters for accessibility
For deaf, hard-of-hearing, or environment-impaired viewers, captions only work if they're synchronized with spoken word. Captions that lag 5-10+ seconds are unusable — viewers can't follow the conversation in chat, can't react to gameplay events, and often abandon the stream.
Real-time accessibility means captions appear within 1-2 seconds. Our pipeline (Deepgram nova-3 transcription) is optimized for that latency window.
Built for accessibility, not just speed
- Customizable font size — slider 20-80px for low-vision and small-screen viewers
- Adjustable outline / contrast — meets WCAG 4.5:1 contrast minimum on any background
- Position control — top, bottom, custom — viewers don't lose facecam or gameplay info
- Word-by-word streaming — captions arrive as you speak, not in 5-sec chunks
- Multilingual support — same-language captions OR translated captions for international accessibility
Use cases for real-time accessibility
- Deaf and hard-of-hearing viewers — primary intended audience for captions
- Mobile viewers with sound off — 80% of Twitch mobile viewers stream silently in public
- Non-native speakers — captions help comprehension even for hearing audiences
- Heavy-music gameplay streams — captions cut through audio noise
- Educational and corporate live broadcasts — required for compliance
