- Closed captioning’s most important use is to give those that are deaf, hard of hearing, or other disability such as a cognitive impairment the ability to understand what is being said (or the sounds) by displaying the written word on television or an online video.
- A second reason for closed caption is for those learning the language. Whether it is someone simply learning to read and speak or someone learning a new language closed captioning can help with that. In some cases such as on online videos it can be used to translate easier into another language.
- To avoid noise from Television sometimes closed captioning is used. This may be in an apartment building at night, a work place, a college, a school, or a busy restaurant or airport. A similar reason may be if there are no speakers on a computer or the speakers can’t get loud enough to hear.
- A fourth reason for online videos is the ability to have words searchable for video content and it can be used for a written transcript as well.
