Accessible Audio & Video
summary
Explains concrete workflows: use YouTube auto captions as a starting point, then convert and clean files (VTT/SRT) or feed a human live captioner for events; typical edit effort is about 2–3 hours per recorded hour when done manually. Mentions tools Whisper and Audiate for improved transcription, Islandora/Video.js for delivery, and WCAG rules: live media needs captions at AA while pre‑recorded media requires audio descriptions or an alternative (often a transcript).
