Quick Answer
Live captioning is the real-time display of spoken words as on-screen text during a live stream. For streamers, it means showing captions as you talk — not after editing. Improves accessibility for deaf viewers, non-native speakers, and viewers in noisy environments.
Live Captioning Explained
Live captioning happens while you're live — no editing required. 1 in 8 Americans aged 12+ has some hearing loss (NIDCD, 2023). While streaming doesn't legally require captions, it's increasingly expected as an accessibility standard.
- Real-time, not edited
- Typically 85-95% accuracy for clear audio — varies by accent, background noise, and the quality of the AI model used
- Can be same-language or translated
- Improves accessibility for deaf, HoH, and non-native viewers

Captioning Stats
80% of people who use captions aren't deaf (Ofcom, UK). YouTube reports captions give 80% higher completion rate with captions (Verizon Media, 2019). For live streams, the effect is similar — viewers who read along stay longer.
