Freelock Highlights Captioning and ASL Accessibility in Advent Day 16 Post

Staff Reporter

Freelock’s Day 16 entry in its Drupal Advent Calendar focuses on making video content accessible by using captions and, when appropriate, American Sign Language (ASL) interpretation. It explains that while captions are a WCAG requirement for prerecorded and live audio (Levels A and AA), sign language is considered Level AAA, strongly recommended for content serving Deaf communities but not mandatory for compliance.

The post highlights that ASL is a separate language from English, making captions less effective for those whose first language is sign. Facial expressions and visual nuances in ASL convey tone and meaning that captions cannot replicate. Freelock notes that while only a small percentage of people with hearing loss use ASL primarily, offering both captions and sign language interpretation ensures broader inclusivity.

To support accessibility in Drupal, Freelock recommends the Able Player module, which enables uploading caption files and supports multiple languages. The blog also outlines how to create high-quality captions using automated tools, human services, or hybrid approaches, and encourages providing transcripts as an additional access layer. It concludes by underscoring that accessibility requires offering multiple formats to serve different needs effectively.
