How do I add captions to a slide deck automatically?
Last updated:
Generate captions from your narration transcript, then sync timings at slide or segment level.
Automatic captions are fast to produce, but they still need review for names, acronyms, punctuation, and product terminology. Without that QA step, caption errors can reduce comprehension and trust.
A practical workflow is:
- generate transcript from final narration
- auto-create timed captions by segment
- review high-risk terminology manually
- test readability on mobile and desktop
For accessibility, ensure contrast and caption placement do not block critical slide content. If your audience includes non-native speakers, captions also improve comprehension even when audio quality is strong.
Keep transcript files versioned so caption updates stay aligned whenever narration changes.
Captions also help in low-audio environments where viewers cannot listen with sound, which increases practical completion in real-world buyer workflows.
Where possible, include both inline captions and a downloadable transcript so viewers can choose the format that best fits their context. Quick reference: Auto-generate captions, then run a quick terminology and timing QA pass before publishing.
