Live captioning for the deaf and hard of hearing

Make every moment accessible, for everyone

Millions of people worldwide are deaf or hard of hearing. Live captioning makes sure nobody misses a word, without needing to book a sign language interpreter.

From church services to corporate events and meetings: the spoken word is often difficult or impossible for deaf and hard-of-hearing attendees to follow. Live captioning changes that instantly.

Trandelion turns spoken words into written captions within seconds. Just like our translation solutions for events and church services, you choose the format that best fits your venue and audience.

Four ways to follow along live

1

The most popular choice: Captions on your own mobile

Visitors scan a QR code at the entrance and see the captions appear live as text on their own screen, at their own pace.

  • Why this is the standard: No special equipment needed, and everyone can adjust text size to what feels comfortable.
  • The trade-off: It requires a phone in hand, which some visitors may find less desirable than a shared screen.
2

Captions on a large screen or beamer

The captions are displayed directly on a screen at the front of the room, visible to everyone at once.

  • Why this is chosen: Low-threshold, no app or phone required. Ideal for visitors who are less digitally comfortable.
  • The trade-off: Limited space on screen, and less suitable for large rooms where text at the back becomes hard to read.
3

Captioning and translation combined

For deaf and hard-of-hearing attendees who also speak another language, the captions are simultaneously translated into their own language.

  • Why this is chosen: Double accessibility: both hearing loss and a language barrier are solved at once.
4

Listening directly through the hearing aid

Besides reading, the translation can also be listened to directly as audio. Because the solution works via the visitor's own smartphone (Bring Your Own Device), hard-of-hearing attendees can stream the sound straight to their Bluetooth-connected hearing aid or cochlear implant.

  • Why this is chosen: No separate receiver or earbuds needed; the sound comes in through the device someone already wears, clear and free of background noise.
  • The trade-off: The hearing aid needs to support Bluetooth pairing with a smartphone, which most modern devices do.

Which captioning option suits your venue?

When making this choice, we advise looking at the size of the room and the needs of your visitors:

Large or changing groups of visitors? Choose captions on mobile, so everyone can follow along at their own pace.
A fixed venue with regular visitors? A screen at the front of the room is low-threshold and requires no installation on the phone.
Deaf or hard-of-hearing attendees who also speak another language? Combine captioning with translation for maximum accessibility.
Many visitors with a hearing aid? Offer the option to listen in directly via Bluetooth, alongside the captions.

Why AI captioning is the solution

A sign language or live-text interpreter isn't always available in time and can be costly. AI software provides the solution:

1
Always available: no interpreter needs to be booked in advance, even for unexpected or last-minute moments.
2
Lightning fast: captions appear within seconds of the spoken word.
3
Affordable: low cost per event or service, accessible for every organisation.
