Subtitles are text displayed on a screen that transcribe or translate the spoken dialogue in a video. They help viewers understand the content, especially when the audio is unclear or in a different language. Subtitles can be found in movies, TV shows, and online videos, making them accessible to a wider audience. There are two main types of subtitles: closed captions and open captions. Closed captions can be turned on or off by the viewer, while open captions are always visible. Subtitles enhance the viewing experience for people who are deaf or hard of hearing, as well as those learning a new language.
