Caption writers, stenocaptioners, or stenographers, produce real-time transcription of the spoken word, onto a screen.
Using machine shorthand, caption writers are able to keep up with the spoken word. By linking their stenotype machine to a computer, live captions can be streamed to one or more individual computer screens or projected onto a large screen for many viewers.
Live captions can be produced onsite or remotely and streamed via a web link.
