Captioning only satisfies one element of the Section 508/WCAG 2.0 success criteria - those only help the hearing impaired and even then only have limited utility since they are embedded in the video playback device which screen readers often cannot access. Video should also have audio descriptions that describe meaningful action or other text-based information that is only displayed on-screen.

A helpful success checklist is https://www.hhs.gov/web/section-508/making-files-accessible/checklist/av-508-checklist/index.html. See esp. item B8.

Captioners should also strive for 100% accuracy, although this is challenging even for manual captioning with low-fidelity source audio or domain-specific language.

Yeah, it's the domain specific terms that really make or break these systems, especially in academic settings. These might suffice for business domains, but I've seen transcription quality drop quite fast for a STEM class or any non-Western humanities course. Ideally, there would be a feedback loop to these systems but I have yet to see one where you can send in corrections.

Hi everyone,

Thank you so much for your replies! I'll reply to each of you individually as well.

In answer to your question about which auto-captioning solutions we're looking at, there are 2 main solutions we have our eye on. One is VerbIt and the other is Konch. Both appear to offer reasonable accuracy in the languages we need, though we are still evaluating. Still, as with any of these solutions, they miss some domain-specific vocabulary as well as anything that's mumbled or otherwise hard to understand. Also, we need to figure out our workflow for generating captions/transcripts, getting them into our infrastructure, and allowing for hand corrections and the workflow for revisions resulting from same. The devil is in the details!

Best wishes,

Carol
