# Conferences and keynotes

Conference audiences follow along in the room, on their phones and in the livestream at the same time. Line 21 captions each session once and sends it to all of them, in as many languages as your audience speaks.

Book professional captioners for the sessions that matter most, use AI for the breakout rooms, or mix the two across the programme.

Covers: Keynotes and speakers, Panels and discussions, International conferences, Summits and expos, Awards ceremonies.

## What makes it hard

**Names, brands and jargon**: Speakers rattle off product names, acronyms and the names of fellow panellists. Generic captions get them wrong at the worst moment.

**Several audiences at once**: The room needs captions on screen, remote viewers need them in the stream, and international guests need their own language.

**Fast exchanges**: Panels, Q&A and award announcements move quickly, between several speakers, with no second take.

## How Line 21 handles it

### Brief the AI like a captioner

Add the agenda, slides and speaker list. The AI Proofreader uses them to fix names and terms in every line before it is shown.

### Professional captioners where it counts

Accredited stenographers and respeakers for keynotes and high-stakes sessions, working on the same platform as the AI.

### Every language in the room

Each caption line is translated live, and attendees pick their language on the captions page.

Show captions on venue screens with the browser page or the overlay, share a QR code for phones, and add them to your livestream.
