Definition embed elements used for audio only must have caption or text transcription of the audio content.
Purpose
  • Captions and text transcripts provide a means for people cannot hear the audio to understand the audio content.

  • When the language of the audio is different than the native language of the listener, captions and text transcripts support the listner in understanding the audio content.

Target Resources embed elements

Techniques
  • Use the audio element instead of the embed element for audio only content, since the audio element provides better support for captions and text transcripts.
  • Use aria-describedby attribute to point to a text description of the audio only content.
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.

Element Results

Column Definitions

Element Identifier
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
Element Position
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
