CART and Live Captioning Services
Short answer: White Coat Captioning provides CART (Communication Access Realtime Translation) and live captioning — real-time, word-for-word text of what is being said, written by a professional stenographer — for conferences, lectures, commencements, webinars and meetings. We work on-site or remotely, anywhere in the world, and we specialize in technical, medical and academic content.
CART, live captioning, realtime captioning — what’s the difference?
None that matters to you. CART is the term used by the ADA, by disability-services offices, and by most universities. “Live captioning” and “realtime captioning” are what the events industry calls the same thing. In every case a trained stenographer listens and writes, and the text appears on screen less than a second later. If your accommodation request says CART, we’re the people who fulfill it.

On-site or remote
The best result usually comes from having the captioners in the room, working side by side with your AV and production team: instant troubleshooting, a view of the slides, and no internet between us and you. When budget, space or distance rule that out, remote captioning with the same captioners is excellent — we’ve captioned remotely from Australia to India to France to California, and audiences regularly don’t believe we’re not on site. We’ll tell you honestly which is the better fit for your event.
How the captions reach your audience
Wherever they need to be, and to more than one place at once if you need it:
- On a screen in the room — open captions on a monitor, projector or Jumbotron
- Inside your meeting platform — Zoom, Webex, Teams and others
- On a private link each attendee opens on their own phone, tablet or laptop
- On your livestream, alongside the in-room captions
We use purpose-built streaming technology with no buffering, so the delay is a fraction of a second when the venue’s internet is sound. (Conference wifi is usually the weak link — we’ll tell you what to ask the venue for.)
What’s included
- Preparation: we build a custom dictionary from your program, speaker list, slides and glossary before the event
- Expert captioners, each tested by us before they work an event, writing at 260+ words per minute with accuracy very near 100%
- Lightly edited transcripts of every session, delivered to a shared folder afterwards
- A team sized to your event — long days and multiple tracks are staffed properly, not stretched
- A captioning company that does one thing. We don’t sell interpreting, AV or “AI-assisted” packages. We caption, and we caption well. Why human captioners →

Frequently asked questions
What does CART stand for?
Communication Access Realtime Translation. It means live, verbatim speech-to-text by a trained stenographer, delivered as the words are spoken.
Is CART the same as closed captioning on TV?
Same skill, different delivery. Broadcast captions are encoded into the TV signal; CART is delivered to a screen, a device or a meeting platform at your event. Our founder, Norma Miller, is a Certified Broadcast Captioner as well as a Certified Realtime Captioner.
Do we need CART if we only have one attendee who asked for it?
Legally, often yes, and in practice the captions get used by far more people than asked. Dartmouth found hundreds of guests reading commencement captions that were arranged for a handful.
How far in advance should we book?
As early as you can for multi-day or on-site events, especially in spring commencement season and fall conference season. We’ve staffed events on a few hours’ notice, but we’d rather plan with you.
Do you provide transcripts or SRT files?
Lightly edited text transcripts are included. We don’t produce SRT files, but our transcripts are easy to turn into captions for YouTube or Vimeo. How to add captions to YouTube videos →
Is remote CART HIPAA compliant?
Yes. See our FAQ for the FCC guidance on relay and captioning services in healthcare settings. If your organization requires its own HIPAA training, our captioners will complete it at our regular rates.
