WCAG 1.2.6: Sign Language (Prerecorded) (Level AAA)

Think about watching a video where the dialogue is in a language you don’t fully understand—without translation, you’d miss much of the meaning.

For many people who are deaf or hard of hearing, sign language is their primary language, and spoken or written content doesn’t fully bridge the gap.

Sign Language (Prerecorded) ensures that everyone can experience videos in the language that feels most natural to them, providing a richer and more complete understanding.

Who this impacts

  • People who are deaf and use sign language as their first language: Sign language can convey meaning more directly and naturally than written text.
  • People with cognitive impairments: Sign language can aid comprehension for those who process visual content more effectively than written language.
  • Sign language learners: Providing sign language content can also support learning by helping viewers follow along with both sign language and written text.

How to meet Sign Language (Prerecorded)

  1. Provide a sign language interpretation video: Feature a sign language interpreter who communicates the spoken content in a corner of the video.
  2. Synchronize interpretation with the original audio: Ensure the sign language appears in real-time, matching the pace of the spoken content.
  3. Embed or offer as a separate version: The sign language video can be either embedded into the original content or provided as an alternative viewing option.

Top Tips

  • Consider regional variations: Different countries have different sign languages. If you have an international audience, consider multiple versions (e.g., ASL, BSL).
  • Work with native sign language users: Native speakers can ensure the interpretation is accurate and culturally appropriate.
  • Position the interpreter well: Make sure the interpreter is clearly visible and does not obstruct important visual content.
