Closed captions are text displays that provide a written version of the spoken dialogue and sounds in a video. They are often used in movies, television shows, and online videos to make content accessible for people who are deaf or hard of hearing. Closed captions can also include descriptions of sound effects, music cues, and speaker identification. Unlike subtitles, which typically translate spoken language, closed captions convey all audio information. Viewers can usually turn closed captions on or off using their device settings. Many streaming platforms, such as Netflix and YouTube, offer closed captioning options to enhance accessibility for their audiences.
