Real-time captioning makes live events accessible to everyone — deaf and hard-of-hearing attendees, international audiences, and viewers in noisy environments. In 2026, AI-powered options have become accurate enough to replace expensive human CART captioners for most use cases.

AI vs Human Captioning
- AI captioning (StreamTranslate, LocalVocal): $0–$20/month, 95%+ accuracy, instant setup, multi-language translation
- Human captioning (Rev, Verbit CART): $100–$300/hour, 99%+ accuracy, scheduling required, English-only typically
For live streams and most online events, AI captioning is the clear winner on cost-effectiveness. StreamTranslate adds the unique benefit of real-time translation — something even $300/hour human captioners can't do.
