Use Cases

Every situation covered

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

🎤Keynotes and main stage talks

From a far seat in a keynote hall at LITEXPO in Vilnius, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Lithuanian keynote from any seat.

🔬Academic and research conferences

At an academic conference — a research congress at a Vilnius university or a scientific meeting in Kaunas — presenters speak fast and mix in terminology. Captio AI captions in real time and transcribes for later review.

💼Industry and professional events

Industry events, technology and fintech summits, and product launches in Vilnius carry content that affects your work. Captio AI captions every speaker so you follow the panel.

📋Workshops and breakout sessions

In a workshop or breakout, several voices contribute in Lithuanian from around the table. Place Captio AI on the table and follow every contribution, including from the back of the room.

🤝Networking and informal sessions

The most useful conversations often happen over coffee breaks and at the conference dinner. Captio AI works in these noisy, informal settings the same way it does in the main hall.

🌍International and multilingual events

At an international conference in Lithuania, sessions switch between Lithuanian and English. Live Translator captions foreign-language talks in real time so you follow the full programme.

Why Captio AI

Built for the room where you cannot ask anyone to repeat

Live captions from any seat

Point the phone toward the nearest PA output or speaker. Captio AI captions whoever is presenting in real time — from the front row or the back of a large conference hall.

Works without venue infrastructure

No hearing loop, no captioning service, no advance booking required. Captio AI works independently via microphone — whether or not the venue has provided any accessibility infrastructure.

Covers what official captioning does not

Official captioning, where it exists, typically covers the main stage only. Q&A sessions, workshops, breakouts, and networking are usually left uncaptioned. Captio AI covers all of it.

Record and review after

Record any session and upload it to Audio Transcription for a full written record. Use AI Summary to extract key takeaways — useful for dense technical content you want to process at your own pace.

60+ languages

For international conferences, foreign-language keynotes, or multilingual panels. Live Translator captions and translates in real time across 60+ languages with no manual switching between speakers.

Works for networking too

The conversations in hallways and at lunch matter as much as the sessions. Captio AI works in any setting — informal, noisy, unstructured — the same way it works in the main hall.

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 sounds. The distinction is pure pitch movement, so from a distant stage a deaf attendee sees identical mouths 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, so a deaf attendee sees the same mouth for pairs that carry different words in a keynote.

Samogitian dialect gap

  • Coastal speech diverges sharply from the standard
  • Standard Lithuanian is based on the Aukštaitian dialect, but Samogitian, spoken toward the Baltic coast, shifts vowels and diphthongs heavily. A conference may bring both to the same panel, so a deaf attendee calibrated to standard Lithuanian meets very different vowel shapes from a coastal presenter.

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 podium speech those unstressed endings shorten and their vowels weaken — so the very part of the word that signals its grammatical role is the part that disappears first from the lips.

Lithuanian–English code-switching

  • Technical English inside Lithuanian sentences
  • Lithuanian technology and academic speech, especially in Vilnius's fast-growing tech and fintech sector, drops English terms into Lithuanian sentences constantly. A deaf attendee lip-reading Lithuanian meets English phonology on the key vocabulary, then returns to Lithuanian, with no visual signal of the switch.

The Challenge

Hearing loss and professional access 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. Specialists also estimate around 12,000 deafblind people in the country, in a nation of fewer than three million. Many deaf and hard of hearing Lithuanians reach professional life under-supported.

Vilnius and Kaunas host a growing conference and events sector — the academic congresses of their universities, the technology and fintech summits at venues like LITEXPO. These run on spoken Lithuanian delivered over PA systems, with English woven into technical sessions. Real-time Lithuanian captioning of keynotes, panels, and Q&A is essentially never provided, and where any accessibility exists it does not reach the breakouts and networking where professional value is built.

Captio AI closes that gap. Point the phone toward the PA and read every Lithuanian keynote and panel answer from any seat, record a dense session for the full transcript, and follow the conversations over a coffee break — so a deaf professional in Vilnius or Kaunas gets the same value from the same conference as everyone in the hall.

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.

"Vilnius fintech talks drop English terms into Lithuanian on every point, delivered fast from a far stage. I caught fragments. Captio AI captioned both from my seat. I read the whole session and knew exactly what the launch meant for my team."

"Samogitian coastal speech is different from Vilnius Lithuanian, and the panel had both. Captio AI captioned every speaker and the audience questions. As a panellist I answered what was actually asked instead of guessing."
