Captions for Hard-of-Hearing Viewers
Live captions designed for hard-of-hearing audiences — large font support, high-contrast outlines, real-time accuracy. Setup takes 60 seconds in OBS.
Hard-of-hearing isn't the same as deaf
Hard-of-hearing viewers can hear but rely on captions to fill gaps — especially in noisy environments, with mumbling speakers, or with heavy background music. Captions for this audience need to be highly readable: large font, clear outline, fast updates.
Most automatic captioning tools default to small fonts and slow chunked updates that frustrate hard-of-hearing users. We made the controls explicit so streamers can dial them in for max accessibility.
Customization for hard-of-hearing audiences
- Font size up to 80px — slider in the control panel, real-time preview
- 2-4px outline — adjustable thickness so text is readable on any background
- High-contrast colors — white-on-black, yellow-on-black, or any custom combo
- Word-by-word streaming — captions appear as you speak, not in 5-second chunks (chunked captions are bad for hard-of-hearing viewers who use them to reinforce hearing)
- Latency under 2s — caption is on screen by the time you finish the next word
How it works in OBS
- Sign up at /control — 6 hours free
- Pick your spoken language as both the source AND the target language (e.g. English → English)
- Copy the browser source URL
- In OBS: Sources → + → Browser Source → paste URL → set width 1920, height 1080 → done
- Captions appear over your scene — adjust position via OBS or our font controls
Why hard-of-hearing viewers stay longer with captions
Hard-of-hearing viewers don't always announce themselves in chat. But they tell us in DMs and Discord: "I leave streams without captions in 30 seconds. I stay 60 minutes when there are captions."
The retention math: even a 5% retention boost from accessibility = significantly higher Twitch viewer-hour metrics, which feeds into recommendation algorithms, which compounds your channel growth.
