Closed captioning will allow not only the deaf and/or hard of hearing learners to access your content, but also those who use English as a second language

Use closed captions or transcripts as meta data to make your video text-searchable, and to make web-embedded video search engine friendly.

With the increasing popularity of mobile devices, viewers may be in environments where access to the audio is limited. Closed captioning allows them to view content whether they are in the library, at a concert or on a noisy bus.
