AI captions & accessibility

Caption everything. Unlock everything.

MEDIAL’s in-house AI speech recognition makes it affordable to caption every video you publish. Those captions then power in-video search, automatic chapters, AI quizzes and AI Video Moments, so accessibility and engagement go hand in hand.

AI Captions & Accessibility

An accessibility workflow that runs itself

  • Automatic AI captions

    Caption uploads automatically for selected users or groups, or let publishers request captions on demand.

  • Permissions & approvals

    Choose caption profiles, who can request them, and who approves requests, so the workflow matches your policies and budget.

  • Caption editor

    Correct ASR output in a simple editor with search and find-and-replace for recurring terms.

  • Multi-language captions & audio

    Offer up to 10 caption languages and multiple audio tracks per video. Learners switch without restarting playback.

  • Search inside video

    Captions are indexed so learners can search for a keyword and jump to every moment it was spoken.

  • Human captioning option

    Need higher accuracy for a key recording? Request professional human transcription alongside AI captions.

  • Auto-generated, searchable moments
  • Natural-language search across indexed media
  • Manual requests or automatic creation by group

  • Viewer-adjustable caption styles
  • VPAT available on request

FAQ

Frequently asked questions

How accurate are MEDIAL’s AI captions?

MEDIAL runs an in-house automatic speech recognition pipeline based on OpenAI’s Whisper model, which performs well on lecture and training content. Publishers can edit captions, and human transcription is available when higher accuracy is required.

Can captions be generated automatically?

Yes. Administrators can auto-caption uploads from selected users or groups, let users request captions manually, or set up an approval workflow.

Do you provide a VPAT?

Yes. Our Voluntary Product Accessibility Template is available. See the Accessibility page or contact us for the latest copy.
