What is a live caption display for an event?

A live caption display is a shared screen (LED wall, projector, or room display) that shows real-time captions so the whole room can read along without joining on individual devices.

What are phone captions?

Phone captions are captions delivered to each attendee’s device (usually via a browser link). Each attendee can choose their view and reading distance, but it increases support and depends on device and network behavior.

Which is better: a shared caption display or phones?

Neither is universally better. A shared display reduces per-attendee support and works well for a single room with clear sight lines. Phones offer personal accessibility controls and can serve remote attendees, but they depend on network/device behavior at scale. Many events use both: a shared display for the room plus phones for overflow or remote listeners.

Do caption screens replace professional interpreters?

No. Captions and interpretation solve different needs. A responsible event plan keeps qualified human interpreters for high-consequence sessions where required, and uses captions as an accessibility aid or as part of a broader multilingual workflow.

Caption display vs phone captions

A shared caption screen (LED or projector) reduces support burden in a room. Phone captions offer personal accessibility controls and remote reach. The best answer is often a mixed plan.

The direct definition

“Caption display” means one shared screen showing captions for a room. “Phone captions” means each attendee opens captions on their own device (typically via a browser link). Both can be correct. Your job is to choose the failure mode you can support.

Shared caption display (LED/projector)

Best when one room needs a common view: keynotes, town halls, ceremonies, and sessions with a stable stage and sight lines.

Lower attendee support burden: no per-person join flow required.
Works for attendees without headphones or without a spare device.
Good for visible accessibility commitments in the room.
Depends on sight lines; not ideal for people far away or with low vision.

Phone captions (personal devices)

Best when the audience is distributed: remote attendees, overflow rooms, multi-site events, or participants who need personal accessibility control.

Personal reading distance and accessibility preferences.
Can serve remote audiences without camera sight lines.
Join flow and network scale become operational responsibilities.
In-room phone use can increase distraction; plan expectations.

The mixed plan (often the safest)

Many events run a shared caption display for the room and still provide phone captions for remote, overflow, or accessibility needs. This reduces help-desk load in the core room while keeping a personal option available.

What to test before you promise either option

A caption plan fails in predictable ways. The safest approach is to rehearse the exact audience conditions and document the support plan.

If you rely on a shared display

Sight lines for every seating zone (including overflow and wheelchair positions).
Font size and contrast in the actual lighting conditions.
A contingency if the projector/LED feed fails (secondary screen or phone captions).
A speaker-change or Q&A cue plan so captions remain readable.

If you rely on phones

Venue network behavior under realistic concurrency (not a single phone).
A simple join instruction + staffed help path for connection issues.
Headphone policy to prevent echo and reduce distraction.
A fallback if the network fails (shared display, receivers, or reduced scope).
