AI vs. Human Audio Description Workflows: How to Choose the Right Approach for Your Video Library
Audio descriptions are required for pre-recorded video content under WCAG 2.1 AA and ADA Title II. They make visual information accessible to blind and low-vision viewers by narrating actions, settings, on-screen text, and other elements that are not conveyed through dialogue or sound effects. With the ADA Title II compliance deadline in April 2026, institutions managing large video libraries need to decide how to produce descriptions at scale.
