Designed for the real moments that matter — not just quiet controlled environments.
At Heathrow, O'Hare, or Sydney, gate changes and boarding calls come over PA systems with regional accents and terminal noise. Captio AI captions every announcement so you never miss a boarding time or gate change.
The London Underground, Amtrak, or Sydney Trains announce platforms and delays via staff and PA. Captio AI captions whoever is speaking — at the ticket counter, on the platform, or through the overhead system.
A hotel receptionist in Edinburgh or New York explaining room rules, check-in details, and local tips. Place Captio AI on the desk and follow every word of the conversation without asking for repeats.
Asking a local for directions in London, getting advice on a Chicago street corner, or following a ranger briefing at a national park. Captio AI captions in real time so you understand the first time.
US Customs and Border Protection, UK Border Force, or Australian Border Force officers speak quickly and precisely. Captio AI captions every question so you answer confidently.
A museum guide at the Smithsonian, a walking tour of Edinburgh's Old Town, or a ranger briefing at the Grand Canyon. Captio AI captions the guide word by word so you follow the full story.

Built for a world that announces everything by sound
Captions any spoken exchange in real time
Airport staff, hotel receptionists, taxi drivers, tour guides. Hold the phone toward whoever is speaking and read the captions — in any setting, in any country.
60+ languages — no language barrier
Live Translator captions and translates in real time. They speak their language — you read in yours. For every country, every language, no manual setup between interactions.
Works anywhere with a data connection
Wi-Fi or mobile data. A local SIM or roaming plan keeps Captio AI running in any country — airports, hotels, rural areas, and everywhere in between.
Handles travel environments
Noisy airports, busy stations, echoing hotel lobbies. Captio AI is built for real environments — not quiet controlled rooms. It captions through the ambient noise of travel.
Discreet in any public setting
Hold the phone or place it near the speaker. Captio AI runs quietly and draws no attention — useful in customs, immigration, and any formal travel interaction where discretion matters.
Private by default
Travel conversations — customs declarations, hotel bookings, personal exchanges — are never stored or shared. Audio is processed in real time and discarded immediately.
Why English is hard to understand
Accent diversity
- One language, dozens of mouths
- English is spoken across the UK, USA, Australia, Ireland, Canada, and South Africa — each with distinct vowel shapes and rhythms. A deaf traveler who lip-reads one accent fluently can be completely lost when a Glaswegian receptionist checks them in or a Texan border officer asks a question.
Dental fricatives
- Invisible sounds at the counter
- The th sounds — /θ/ as in 'three' and /ð/ as in 'the' — are produced with the tongue between the teeth, producing almost no visible lip movement. 'Thank you', 'this gate', 'the third floor' — common phrases at airports and hotels where the most informative sounds disappear entirely on the lips.
Fast connected speech
- Elision and linking collapse word boundaries
- In natural English, words blur together: 'did you' becomes 'didja', 'going to' becomes 'gonna', 'don't you know' becomes 'dontcha know'. Airport staff, hotel receptionists, and customs officers speaking at conversational pace produce a stream where individual words are impossible to segment visually.
Homophones and near-homophones
- High-stakes words that look identical
- At customs and check-in, 'gate eight' and 'gate late', 'aisle' and 'I'll', 'right' and 'write' are visually identical. In a high-stakes travel exchange — catching a flight number or a departure time — homophene pairs mean one missed cue sends you to the wrong gate.
Regional vowel shifts
- The vowel that moved
- The Northern Cities Vowel Shift in American English, the GOAT-FOOT merger in South African English, and the trap-bath split in British English all mean the same words look different on different speakers' lips. A traveler calibrated to RP British may find an Australian customs officer nearly unreadable.

In the UK, over 18 million adults are deaf, have hearing loss, or have tinnitus — a number revised upward by RNID in 2024, with 2.4 million adults unable to hear most conversational speech and 900,000 severely or profoundly deaf. In the United States, around 38 million Americans have significant hearing loss, with the National Institute on Deafness estimating that 28.8 million could benefit from hearing aids. These populations represent the majority of English-speaking travelers navigating airports and transit hubs built almost entirely around audio announcement systems.
Despite legislative frameworks like the UK Equality Act 2010 and the US Air Carrier Access Act, real-time audio accessibility at airports and transport hubs remains inconsistent. Induction loops cover limited areas, visual information boards do not replicate every PA announcement, and live captioning at gate counters is rare. The FAA Reauthorization Act of 2024 mandated enhanced accessibility at US airports by 2028 — but that deadline is still years away. For deaf and hard of hearing travelers today, the system assumes they can hear.
Captio AI captions English speech in real time — gate announcements, hotel receptionists, customs officers — so a deaf traveler at Heathrow or JFK follows every exchange without relying on a system that was not designed for them.

Gone the moment it ends
Captio AI processes your audio in real time and discards it immediately. Nothing is recorded. Nothing is kept.
Not a product
Your conversations are not something Captio AI sells, shares, or monetizes — to anyone, for any reason.
Not used to train anything
What you say in a doctor's appointment or a job interview never ends up in a training dataset. Not ours. Not anyone else's.

People love Captio AI
"Heathrow is a nightmare for lip-reading — staff are behind glass, noise everywhere, accents vary by gate. Captio AI turned every counter interaction into a readable conversation. I caught my connecting flight because I read the gate change on screen."
"Customs at O'Hare used to mean guessing what the officer was asking. Now I point Captio AI and read every question word for word. The difference between a confident answer and a misunderstanding is significant at a border."
"Australian accents are very different from what I was calibrated to lip-read. Captio AI doesn't care which accent it is. Hotel check-ins, hostel staff, tour guides — it handles all of them the same way."
"I travel for work across Canada and the US. Accent variation used to make every new city a fresh challenge on my lip-reading. Captio AI just reads the speech — no adjustment needed from me."
