What are captions?
Captions are text-based alternatives to multimedia content. The spoken dialogue and sound effects from the original soundtrack are displayed on screen in real time as the video plays.
Why are captions important?
Captions present the same information that is provided either through audio-only content or audio content that is synchronized with video content. Providing captions helps to ensure that the audio is available to individuals who are unable to access information presented in an audible format.
Captions are used to make audio content accessible to people who are deaf or hard of hearing and captions may also help those who may not be fluent in the language used in the audio content.
