Use Cases

Every situation covered

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

✈️Airports and boarding

At Sarajevo International (SJJ) or Tuzla, announcements come in Bosnian and English across a compact but busy terminal. Captio AI captions both languages so you catch every gate change and boarding call.

🚂Train stations and public transport

Intercity coaches are the backbone of travel in Bosnia, and Sarajevo's trams and the ŽFBH railway announce stops in Bosnian. Captio AI captions the ticket-counter exchange and the on-board calls in real time.

🏨Hotels and check-in

A receptionist in Sarajevo's Baščaršija or a guesthouse in Mostar explaining check-in and the way to the Old Bridge in Bosnian. Place Captio AI on the desk and follow the full conversation.

🗺️Navigating and asking for help

Asking directions in Sarajevo's old bazaar or the lanes around Mostar's Stari Most. Fast Bosnian from a local — Captio AI captions the reply so you find your way the first time.

🛃Customs and immigration

Border and customs officers at Sarajevo Airport and land crossings speak quickly in formal Bosnian. Captio AI captions every question so you respond accurately.

🎭Tours and activities

A guide at Mostar's Old Bridge, the Sarajevo Tunnel Museum, or the bridge at Višegrad delivering Bosnian commentary. Captio AI captions so you follow the full history behind each site.

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.

Bosnian

Why Bosnian is hard to understand

Pitch accent

  • Rising and falling tones you cannot see
  • Bosnian inherits the Shtokavian pitch-and-length accent system, where stressed syllables carry rising or falling tones and long or short quantities. These distinctions ride on pitch and duration, not on the lips. Even as the system softens in urban Sarajevo speech, a deaf traveler gets no visual cue for the tone that separates one word from another at a counter.

Ijekavian reflexes

  • The 'ije' and 'je' sequences that reshape words
  • Standard Bosnian uses Ijekavian pronunciation, where the old Slavic vowel jat surfaces as 'ije' or 'je' — mlijeko for milk, rijeka for river. These diphthongal sequences make familiar words look different from the Ekavian forms used elsewhere in the region, so a lip-reader calibrated to Serbian speech meets unfamiliar vowel shapes.

Affricate contrasts

  • Č and ć, dž and đ look almost identical
  • Bosnian distinguishes two pairs of postalveolar and palatal affricates — č versus ć and dž versus đ — that sit very close together in the mouth and look nearly identical on the lips. Bosnian also retains the /h/ sound in words where neighbouring varieties drop it. At a ticket window these fine contrasts decide the word but give a lip-reader nothing to work with.

Regional accent range

  • Sarajevo, Herzegovina, and the Krajina all sound different
  • The Bosnian of urban Sarajevo differs from Herzegovina in the south and the Bosnian Krajina in the northwest — in accent, rhythm, and vocabulary. Intercity coaches connect all of these regions, so over a single journey a deaf traveler encounters several recognisably different ways of speaking.

Fast casual clipping

  • Relaxed speech drops vowels and lengths
  • In everyday Bosnian, unstressed vowels are clipped, post-tonic lengths flatten, and words run together. At a crowded Sarajevo bus station the careful pronunciation that would help a lip-reader collapses into a fast, connected stream.

The Challenge

Hearing loss and travel accessibility in Bosnia and Herzegovina

The deaf population of Bosnia and Herzegovina is estimated at roughly 3.3% of the general population, though researchers stress that the lack of systematic study makes any figure difficult to pin down. Rehabilitation studies have worked with samples of over a thousand deaf and hard of hearing people registered with employment offices and social-care centres — a snapshot of a community whose true size is unknown because the data infrastructure to count it does not exist. This absence of reliable data is itself a barrier: services cannot be planned for people who are not measured.

Bosnia recognised sign language in law in 2009, granting deaf people the right to interpreters when dealing with government bodies and requiring state broadcasts to be interpreted. But standardisation of the language is still incomplete, and the recognition has not translated into accessible travel infrastructure. Sarajevo Airport, the ŽFBH railway, and the intercity coach network that most Bosnians rely on all communicate through spoken Bosnian, with no real-time captioning at counters or platforms. A health and transport system still recovering from the legacy of the 1990s war rarely reaches deaf travelers with the information hearing passengers receive for free.

Captio AI captions Bosnian in real time — a boarding call at Sarajevo Airport, a coach departure at the main bus station, a hotel check-in in Baščaršija — so a deaf traveler in Bosnia and Herzegovina follows every change and question without depending on 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.

People love Captio AI

"The main bus station in Sarajevo is chaos and every departure is called out in fast Bosnian. I missed a coach to Mostar once standing right next to the desk. Captio AI captions the announcements the moment they play. Now I read the platform and walk straight there."

Hard of hearing, Sarajevo — frequent traveler

"Herzegovina speech is different from Sarajevo, faster and with its own accent. Guesthouse owners here lost me at check-in every time. Captio AI captioned the whole conversation — the key, the breakfast, the path to Stari Most — in the local accent without any trouble."

Deaf, Mostar — tourist-town resident

"I travel between the Krajina and Sarajevo and every region sounds a little different on the lips. Captio AI does not care which accent it is — it captioned the border officer's questions at the crossing word for word, and I answered without the usual panic."

Severely deaf, Banja Luka — cross-country traveler

"The guide at the Tunnel Museum spoke quick Bosnian about the siege and the tunnel under the airport. I would normally miss most of it. With Captio AI I followed the whole story — the dates, the families, how the tunnel kept the city alive."
