Version: WCAG 2.0 and up
Number: 1.2.6
Level: AAA
Applicability: Video with accompanying audio

Sign language interpretation is provided for all prerecorded audio content in synchronized media.



The purpose of this success criterion is to ensure that users whose primary means of communication is a sign language can access the auditory content of videos. Written text is not always as easily followed by such users, increasing the difficulty to understand auditory content.

How to Meet

To meet this success criterion, authors must provide synchronized sign language interpretation for the auditory content of any videos used in their publications.

Sign language interpretation typically has to be included in the video stream due to the complexity of synchronizing separate videos.

Additional Information

The knowledge base does not currently include information on adding prerecorded sign language interpretation. Refer to the WCAG guidance documents for additional information.
