A closed caption refers to the text displayed on a screen that shows the spoken words and important sounds in a program, such as dialogue, music, or sound effects. It is often used for people who are deaf or hard of hearing, allowing them to follow along with the content. Closed captions can be turned on or off, giving the viewer control over whether they appear. They are typically available on television shows, movies, and online videos, providing a way to make media more accessible.
