New ADA Title II Deadlines Are Driving Change
From April 2026, state and local governments in the U.S. must make all prerecorded video content accessible under WCAG 2.1 AA – including audio description. For many public entities, this will be the first time audio description is required at scale.
LEXI AD makes compliance achievable and affordable. Our automated, fully WCAG-compliant audio description delivers natural-sounding narration at up to 75 % faster turnaround and a fraction of traditional cost.
Fine-tune your audio descriptions to match your content, audience, and accessibility needs
Tailor audio descriptions to your content, audience, and style with optional controls:
-
Narration Voice – US, UK, or Australian English; male or female.
-
Pacing – Slow (0.5×) to fast (2.0×) to match your video’s rhythm.
-
Video Introduction – Add a short intro or synopsis for the AI to guide descriptions.
-
Guidelines – Specify tone, style, or audience (e.g., “formal” or “under 10”).
-
Timing – Control overlaps, silence between segments, or continuous description.
-
