Captioning

v. write a caption, provide with a caption

Closed captioning (CC) (commonly known as subtitles, and also called subtitles for the hearing impaired) allows people who are deaf or hard of hearing, learning a new language, beginning to read, in a noisy environment, or otherwise disadvantaged to read a transcript or dialog of the audio portion of a video, film, or other presentation. As the video plays, text captions are displayed that transcribe (although not always verbatim) speech and often other relevant sounds.
