Facebook is experimenting with automatic captioning for Stories using on‑device AI, aiming to improve accessibility and engagement.
Overview
The feature listens for spoken words in a Story and overlays editable text captions in real time. Users can tweak the wording and style before publishing.
Impact
Early testers report a 15% boost in Story completion rates among Sound‑Off viewers, and a noticeable increase in Story shares and saves.
Best Practices
- Review and edit captions for accuracy and brand voice.
- Use captions to add context or call‑to‑action prompts for viewers who watch without sound.
- Experiment with different text styles and placements to maintain readability against varied backgrounds.
