Use Cases

Every situation covered

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

🍽️Family dinners

Bosnian family celebrations — Eid gatherings, slava dinners, holiday tables spanning three generations — bring every generation together around food and conversation. Captio AI keeps the full exchange visible for deaf and hard-of-hearing family members.

🎉Social gatherings and parties

Gatherings at home in Sarajevo, Mostar, or Banja Luka fill quickly with overlapping voices. Captio AI follows each speaker in real time so deaf guests can join without depending on others to relay the conversation.

Friend catch-ups

Coffee with Bosnian friends — the classic 'kahva' catch-up — is dense, fast, and hard to lip-read across a small café table. Captio AI surfaces every word so the conversation stays accessible.

🌍Multilingual groups

Neighbourhood meetings, mahala gatherings, and community events use fast conversational Bosnian with local expressions. Captio AI makes the full discussion followable without a professional interpreter.

👥Community and club meetings

When grandparents use older Bosnian vocabulary and younger family members mix in German or Swedish loanwords from diaspora life, the phonological mix widens. Captio AI handles the full range and keeps the multigenerational table connected.

🏠Shared living situations

Social gatherings around football matches, coffee house sessions, or diaspora community events involve rapid exchanges between familiar speakers. Captio AI keeps a deaf or hard-of-hearing member part of every conversation.

Why Captio AI

Built to keep you in the conversation, not just in the room

Captions whoever is speaking

Captio AI follows the dominant voice at any moment — whoever is loudest in the microphone's direction. In a group conversation, this tracks the active speaker naturally.

Works through background noise

Restaurants, living rooms, parties, outdoor gatherings. Moderate background noise does not prevent accurate captions — Captio AI is built for real environments, not quiet rooms.

Place it in the centre and forget it

Put the phone on the table or in the middle of the group, microphone facing the conversation. No positioning it after every speaker change, no adjusting between voices.

Less effort, less fatigue

The cognitive load of following a group conversation by lip-reading and reconstructing speech is exhausting. Captio AI handles the following so you can direct your energy toward actually being in the conversation.

60+ languages

For multilingual families, mixed-language social groups, or gatherings where people switch between languages mid-conversation. No setup required between language changes.

No setup between conversations

Open the app and place the phone. No configuration per setting, no briefing the group, nothing to manage between conversations. It works for any group, in any situation.

Bosnian

Why Bosnian is hard to understand

4-way pitch accent

  • Tone contrasts invisible on the lips
  • Like Serbian and Croatian, Bosnian has four prosodic patterns — short/long combined with rising/falling pitch. These contrasts carry meaning but are produced entirely in the larynx. At a family dinner, 'grȁd' (city) and 'grâd' (hail) look identical on the face.

Ijekavian yat reflex

  • Words look different depending on the speaker's origin
  • Standard Bosnian uses the Ijekavian reflex of Old Slavic *jat* — 'rijeka' instead of 'reka', 'lijepo' instead of 'lepo'. At a gathering with mixed Bosnian, Serbian, and Croatian guests, the same concept arrives with completely different initial lip shapes, creating an unpredictable visual stream.

Turkish-Arabic loanwords

  • A second phonological layer in Bosniak speech
  • Bosnian has absorbed a significant layer of Ottoman Turkish and Arabic vocabulary used alongside South Slavic equivalents. In Muslim Bosniak communities, these insertions — terms for greetings, social occasions, religious moments — introduce phonological patterns that the deaf lip-reader did not encounter in standard classroom Bosnian.

Fast syllable elision

  • Contractions change what the mouth forms
  • Conversational Bosnian drops unstressed syllables aggressively. 'Hoćeš li' (do you want to?) contracts to 'ćeli' in casual speech, changing the visible lip pattern entirely. At a busy family table, these contractions layer on top of the dialect variation and the pitch accent ambiguity.

Dialect contact

  • Regional varieties arrive at the same table
  • Bosnia sits at the intersection of Shtokavian varieties from Herzegovina, the Krajina region, and the diaspora in Germany and Austria. A gathering in Sarajevo may include speakers whose phonology diverges at the level of vowel quality and consonant clusters — each one requiring a visual readjustment.

The Challenge

Hearing loss in Bosnia and Herzegovina: the scale of daily exclusion

A study of deaf and hard-of-hearing people in Bosnia and Herzegovina documented 1,044 individuals registered through formal channels — 455 through employment offices and 589 through social care centres receiving financial aid. This formal count almost certainly undercounts the real population significantly: applying WHO and GBD 2019 prevalence rates to Bosnia's population of approximately 3.5 million suggests somewhere between 500,000 and 700,000 Bosnians live with some degree of hearing difficulty.

The social dimension of hearing loss in Bosnia is compounded by systemic exclusion. Since most deaf people are born to hearing parents, and very few hearing parents learn to sign, many deaf children grow up isolated from their own families. Research from deaf advocacy groups documents decisions made about deaf people without their input, laws historically restricting deaf people in social and legal contexts, and education systems that prioritised spoken language over sign language — often without interpretation support.

Captio AI captions Bosnian conversation in real time, so a deaf or hard-of-hearing person can follow a family dinner in Sarajevo or a neighbourhood gathering in Mostar without depending on others to repeat or interpret.

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.
