Use Cases

Every situation covered

Designed for the real moments that matter — not just quiet controlled environments.

✈️Airports and boarding

At Vilnius Airport (VNO) or Kaunas Airport (KUN), gate changes and boarding calls come in Lithuanian and English. Captio AI captions both languages so you catch every gate number and boarding time.

🚂Train stations and public transport

LTG Link trains and Vilnius trolleybuses announce stops and platforms in Lithuanian. Captio AI captions the ticket-counter exchange and the platform PA in real time so you board the right service.

🏨Hotels and check-in

A receptionist in Vilnius Old Town or a guesthouse in Kaunas explaining check-in, breakfast, and directions in Lithuanian. Place Captio AI on the desk and follow every word.

🗺️Navigating and asking for help

Asking the way through Vilnius's Užupis or along the Curonian Spit. Fast Lithuanian from a local — Captio AI captions the answer so you find the route the first time.

🛃Customs and immigration

Border and customs officers at Vilnius Airport speak quickly in formal Lithuanian. Captio AI captions every question so you respond accurately and confidently.

🎭Tours and activities

A guide at Trakai Island Castle, the Hill of Crosses, or the dunes of the Curonian Spit delivering Lithuanian commentary. Captio AI captions so you follow the full history.

Why Captio AI

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.

Lithuanian

Why Lithuanian is hard to understand

Pitch accent

  • Two tones on long syllables, invisible on the lips
  • Lithuanian long syllables carry either a falling (acute) or rising (circumflex) tone, and the tone alone can separate two different words with the same consonants and vowels. The distinction is pure pitch movement — no lip or jaw change accompanies it. At Vilnius Airport or a Kaunas hotel desk, a deaf traveler sees identical mouth shapes for words that mean different things.

Pervasive palatalization

  • Twenty-two soft–hard consonant pairs
  • Almost every Lithuanian consonant has a hard and a soft (palatalized) form, and the contrast changes meaning. The tongue-body raising that makes a consonant 'soft' is barely visible at the lips. A ticket-counter clerk in Vilnius produces soft and hard pairs that look the same on the face but carry different words.

Samogitian dialect gap

  • Coastal speech diverges sharply from the standard
  • Standard Lithuanian is based on the Aukštaitian dialect, but Samogitian (Žemaitian), spoken toward the Baltic coast around Klaipėda and Palanga, shifts vowels and diphthongs so heavily that it is hard even for other Lithuanians. A deaf traveler moving from Vilnius to the coast meets a different set of vowel shapes on the lips.

Consonant clusters

  • Dense clusters compressed in fast speech
  • Lithuanian permits long consonant clusters at the start and end of words. In the quick speech of a bus station or a border desk, these clusters compress and the individual consonants blur together, giving a lip-reader almost nothing to segment.

Case-ending reduction

  • The endings that carry meaning get clipped
  • Lithuanian marks grammar through a rich set of case endings on the ends of words. In fast, casual speech those unstressed endings shorten and their vowels weaken — so the very part of the word that signals where you are going or what you are being asked is the part that disappears first.

The Challenge

Hearing loss and travel accessibility in Lithuania

Hearing loss reaches around one in five people across Europe, and Lithuania carries a specific genetic burden on top of that baseline: a study of healthy Lithuanians found a GJB2 carrier rate of about 7.1% — roughly one in fourteen — pointing to an unusually high frequency of hereditary hearing loss in the population. Specialists also estimate around 12,000 deafblind people in the country, the great majority of them elderly, in a nation of fewer than three million. Many of these people are navigating the same airports, bus stations, and border desks as everyone else.

Lithuania's travel infrastructure — Vilnius and Kaunas airports, the LTG Link rail network, and the intercity coach services that connect the country — communicates critical information through spoken Lithuanian announcements. Real-time visual captioning is not a standard feature at gates, platforms, or service counters. For a deaf traveler, a delayed connection or a changed platform announced only over a PA system means missing information that everyone around them received automatically.

Captio AI captions Lithuanian in real time — a boarding call at Vilnius Airport, an LTG Link platform announcement, a hotel check-in in Kaunas Old Town — so a deaf traveler in Lithuania follows every change and question without depending on audio infrastructure built without them in mind.

Privacy

What you hear stays with you.

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.

Reviews

People love Captio AI

"Vilnius Airport boarding calls are fast and the pitch accent means words I think I recognise turn out to be something else. Captio AI captioned the gate change in Lithuanian and English. I read it and walked straight to the right gate instead of guessing."

Hard of hearing, Vilnius — frequent traveler

"Samogitian speech on the coast is nothing like the Vilnius Lithuanian I grew up lip-reading. The Palanga hotel receptionist lost me completely. Captio AI captioned every word of check-in — the sauna times, the beach path — and I did not have to ask her to repeat once."

Deaf, Klaipėda — coastal traveler

"Platform changes at Kaunas station are announced fast and only over the speaker. I missed a train to Vilnius once because I could not catch the platform number. Now Captio AI shows me the announcement the instant it plays. I have not missed a connection since."

Severely deaf, Kaunas — LTG Link commuter

"The guide at Trakai Castle spoke quick Lithuanian about the Grand Duchy and the lake. I used to nod along and miss the story. With Captio AI I read the whole tour — the dukes, the karaim community, the wooden bridges — every detail on my screen."
