Captions & Transcripts
Pre-recorded video needs synchronized captions. Pre-recorded audio needs a transcript. Live video needs real-time captions (Level AA). Benefits 430M people with hearing loss plus anyone in a noisy environment.
In plain terms
Text on screen for spoken video, plus a written version of audio — so people who are deaf, or sitting in a quiet office, don't miss anything.
Why this matters
Over 400 million people have disabling hearing loss, and many more watch video on mute in public. Without captions and transcripts your audio and video content is lost to all of them.
How to detect
Quick check
Play each video: are there accurate, synchronised captions — not auto-generated gibberish? Is there a transcript for audio-only content? Check captions cover speaker changes and meaningful sounds.
