Manual Checks |
- Check the web page for a link to a text transcript of the audio, or if the transcript is part of the page rendering the audio.
- Check the media player for a button to turn on and off captions
- When captions are enabled on the media player, check to make sure the captions visible and represent the speech and sounds heard on the audio.
- In some cases "open" captions might be used, this means the captions are alway "on" as part of the video.
