  • Give users, unable to perceive the proposed sound or image, access to a text
  • transcription as an alternative.
  • Give users, unable to hear the sound, access to the information contained in the
  • video.
  • Enable bots to exploit the information, in order to improve its indexing and
  • referencing, or to translate it using online language tools.


Accompany each audio or video content with a transcription:

  • Either complete (containing the words and a description of the sounds and visual elements necessary for understanding);
  • Or an overview (but reflecting all of the information).

The transcription can:

  • Appear on the page where the video or audio content is found;
  • Or be immediately accessible by a link on the page where the video content is located or audio.


Identify each page containing multimedia content and, next to each audio or video content, ensure the presence of a transcription or a link giving immediate access to it.

They have since been revised every five years and have been tried and tested via millions of web interactions by Opquast community’s customers, including the leading CMS communities which have developed plugins for WordPress, Drupal and Prestashop. The most recent version, v4, was established in 2020.
