1.2.9 – Audio Only (Live) (Level AAA)

Provide alternatives for live audio

When broadcasting live audio-only content, such as a live podcast or radio stream, some users will rely on an alternative to the audio to understand your content.

What to do

  • Add closed captions to live audio; or
  • If the live broadcast is from a prepared script, make the script text available from near the original content.


  • To add live captions to an audio broadcast you will need professional software.
  • You may also want to hire a professional subtitler to get the best results.
