Captions should include spoken dialogue and meaningful sounds. Automatically generated captions must be reviewed and corrected for accuracy.
7 Core Skills: Audio & Video
Audio and video can enhance learning and communication, but not everyone can hear or process spoken content. Providing captions and transcripts ensures multimedia content is accessible to all users.
What Makes Audio and Video Files Accessible
Accessible media includes features that allow people to perceive and understand audio content.
For video, this typically means accurate captions that display spoken dialogue and important sounds.
For audio-only content, this means providing a text transcript.
These features allow users to access information in multiple ways and support a wide range of needs and preferences.
Why Is Audio and Video Accessibility Important?
People who are deaf or hard of hearing rely on captions and transcripts to access audio information. Captions also support people in noisy environments, non-native English speakers, and anyone who benefits from reading along with spoken content.
Without accurate captions or transcripts, essential information may be lost.
Providing accessible media improves usability, supports inclusive learning, and ensures digital content can be understood by the widest possible audience.
