Closed Captions

Closed captioning is a process which converts the audio portion of a television program into written words
which then appear as subtitles on the television screen. Clued captions allow viewers to read the dia-
logue and narration of television programs.

Captions are the subtitles of the dialogue and narration of television programs.
For prerecorded programs, program dialogue can be arranged into captions
in advance, its _ssible to caption a live program by using a process called
real-time _ptioning, which creates captions instantly. Real-time captioning is
normally done by professional re_rters using a machine shorthand system
and computer for translation into English
Captioning is an effective system for the hearing-impaired, and it can also aid
in teaching language skills.
