Use Cases

Every situation covered

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

🍽️Family dinners

Lithuanian family celebrations — Kūčios dinners, name-day gatherings, birthday tables — bring multiple generations together at once. Captio AI keeps the full conversation visible, from the quietest grandparent to the loudest cousin.

🎉Social gatherings and parties

Household parties in Vilnius, Kaunas, or Klaipėda fill quickly with overlapping voices. Captio AI follows each speaker in real time so deaf and hard-of-hearing guests can join without depending on others to relay what was said.

Friend catch-ups

A coffee catch-up or after-work drink with Lithuanian friends is easy to miss when background noise rises and voices settle into a normal conversational murmur. Captio AI surfaces every word so the conversation stays accessible.

🌍Multilingual groups

Neighbourhood meetings, seniūnija gatherings, school parent evenings, and apartment building discussions use dense spoken Lithuanian at speed. Captio AI makes the full meeting followable without a professional interpreter.

👥Community and club meetings

When grandparents speak Samogitian or a regional variety and grandchildren use urban standard Lithuanian, the phonological gap widens rapidly. Captio AI captions both varieties, keeping the multigenerational table connected.

🏠Shared living situations

Social clubs — folk singing groups, basketball supporter gatherings, Saturday school events in the diaspora — involve quick exchanges between familiar members. Captio AI keeps a deaf or hard-of-hearing member part of every exchange.

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.

Lithuanian

Why Lithuanian is hard to understand

Pitch accent

  • Two tones, zero lip movement
  • Lithuanian carries two prosodic intonations — acute and circumflex — on long vowels and diphthongs. These pitch patterns change word meaning but are produced entirely in the larynx, invisible on the lips. At a family dinner, distinguishing tone pairs by sight alone is impossible.

Deep palatalization

  • Soft consonants disappear on lips
  • Lithuanian has 45 phonemes — 32 basic consonants each with a palatalized counterpart. Pairs like /p/ vs /pʲ/ or /t/ vs /tʲ/ are produced by the tongue pressing the palate, hidden entirely behind closed lips. Sounds that are audibly distinct look identical on the face.

Žemaitian gap

  • A dialect that reads like a different language
  • Samogitian (Žemaitian), spoken by roughly half a million people in northwestern Lithuania, diverges so far from standard Lithuanian in phonology and vocabulary that it is sometimes classified as a separate language. At a gathering with Samogitian relatives, the lip shapes do not match the standard Lithuanian a deaf person has learned.

Fast casual elision

  • Unstressed vowels vanish at speed
  • In natural Lithuanian conversation, unstressed vowels reduce or disappear and word boundaries blur. Common phrases contract so aggressively that the resulting lip pattern no longer matches the underlying words. Around a busy dinner table, these contractions accumulate faster than a lip-reader can track.

Diaspora code-switching

  • Lithuanian flips to English mid-sentence
  • Lithuanian diaspora communities in the UK, Ireland, and the US code-switch between Lithuanian and English without signalling the shift. For a deaf person reading Lithuanian lip shapes, an unexpected English word breaks the visual phonological pattern entirely and the mouth begins moving in an unrecognized system.

The Challenge

Hearing loss in Lithuania: the scale of daily exclusion

Applying European hearing loss prevalence rates to Lithuania's population of approximately 2.8 million, an estimated 430,000 to 560,000 Lithuanians live with some degree of hearing difficulty — a figure that far exceeds official disability registration numbers, as many people avoid formal diagnosis due to stigma or limited services. The GBD 2019 study found that hearing loss affects one in five people globally and is the leading cause of years lived with disability, with Eastern European countries facing additional gaps in early identification and hearing aid provision.

Lithuania's support infrastructure for people with sensory disabilities is deeply fragmented. An investigative report by Lithuanian public broadcaster LRT found that the country has no functional national system for identifying, supporting, or educating people with combined sight and hearing loss, no tactile version of the Lithuanian language has been developed, and no national organisation represents this population. Specialists estimate roughly 12,000 deafblind people live in Lithuania — the vast majority elderly — yet they remain almost entirely invisible to policymakers and social services.

Captio AI captions Lithuanian conversation in real time, so a deaf or hard-of-hearing person can follow a family dinner in Vilnius or a community gathering in Kaunas without relying on an interpreter or asking others to repeat.

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.
