What you get with Live Human Subtitling
Stenotyping & re-speaking
Integrates with re-speaking software and stenotype keyboards. Professional subtitlers can begin immediately, or you can hire subtitlers and correctors through SabioCast.
Scripted events
Operators pre-write captions for largely predetermined content, with real-time flexibility for speaker improvisation.
Real-time correction
A two-person workflow lets one subtitler correct another's work instantly, before it is displayed. Single-operator correction is also available.
Full language control
Human subtitlers control each language's text per caption — useful where AI translations cannot be edited line by line.
Low-latency friendly
Human subtitling keeps the standard 18-second HLS delay; enabling correction extends it to about one minute.
Formatting compliance
Human operators handle specific accessibility and regulatory formatting rules that strict event specifications may require.
