Uses of Closed Captioning

Language Learning Tool

Apart from placement, closed captioning is a great tool for any non-native English speaker who wants to learn the language. As closed captioning is much more detailed than subtitling, it gives the viewer complete information about a particular scene to learn or improve their knowledge of the respective language.

Absence of Sound

Closed captioning is also very helpful in sound-sensitive or noisy environments such as bars and restaurants to health clubs and airports,. Closed captions facilitate audiences to understand what is happening onscreen when either the background noise is too high or the TV volume is too low.
