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 in Minsk, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Belarusian keynote from any seat.

🔬Academic and research conferences

At an academic conference — a research congress at a Minsk university or a scientific meeting in another city — 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 summits, and product briefings in Minsk carry content that affects your work. Captio AI captions every speaker so you follow the panel and miss nothing.

📋Workshops and breakout sessions

In a workshop or breakout, several voices contribute in Belarusian 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 tea 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, sessions switch between Belarusian, Russian, 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.

Belarusian

Why Belarusian is hard to understand

Akanye

  • Unstressed o merges into a clear open a
  • Belarusian merges unstressed o into a clear open a — even after soft consonants — and spells it that way. Words look different from their stressed forms, and from a distant stage the shifted vowels give a deaf attendee little to segment a long technical term by in a keynote.

Strong palatalization

  • Softened consonants that are hard to see
  • Belarusian is distinctive among Slavic languages for how salient its soft–hard consonant contrast is, including strongly palatalized s and z. The softening is a tongue-body gesture with barely any visible cue, so a deaf attendee sees the same mouth for consonants that make different words.

The ŭ and w-merger

  • A distinctive sound where v and l become a w
  • Belarusian merges v and l into a w-like sound (ŭ) at the ends of syllables — a feature that sets it apart from Russian. This sound gives a lip-reader little clear cue, so a deaf attendee misses a consonant that shapes the word in a technical talk.

Belarusian–Russian mixing

  • Two closely related languages blended together
  • Belarus is deeply bilingual, and professional speech often blends Belarusian and Russian — sometimes in the mixed form known as trasianka. A deaf attendee lip-reading Belarusian meets Russian forms and phonology with no visual warning of the switch, on exactly the technical terms that matter.

Consonant clusters

  • Clusters and hard postalveolars compressed at speed
  • Belarusian permits demanding consonant clusters and has hard postalveolar consonants. In a fast panel exchange these compress into a stream that offers a deaf attendee almost no visual seams between words.

The Challenge

Hearing loss and professional access in Belarus

Against a global pattern in which around one in five people has some hearing loss — and with hereditary hearing loss well documented across the East Slavic region through the distribution of sign-language users — Belarus carries a substantial burden across its population. The deaf community is organised through a long-established national society, but comprehensive, up-to-date national prevalence data is thin, and many deaf and hard of hearing Belarusians reach professional life under-supported.

Minsk hosts a growing conference and events sector — the academic congresses of its universities, the technology and business summits held at large venues in the capital. These run on spoken Belarusian and Russian delivered over PA systems, with English woven into technical sessions. Real-time Belarusian 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 Belarusian keynote and panel answer from any seat, record a dense session for the full transcript, and follow the conversations over tea — so a deaf professional in Minsk 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.

"Minsk tech talks switch between Belarusian, Russian, and English constantly, delivered fast from a far stage. I caught fragments. Captio AI captioned all of it from my seat. I read the whole session and knew exactly what the announcements meant for my team."

"The strong palatalization and the ŭ sound give me nothing on the lips, and the keynote was fast. Captio AI captioned it accurately and I recorded the session. I followed a full congress talk for the first time."

"The panel blended Belarusian and Russian in the same sentence, which used to lose me completely. Captio AI captioned all of it and the audience questions. As a panellist I answered what was actually asked instead of guessing."

"Networking over tea is where the useful conversations happen, and it used to be the part I stepped back from. Captio AI captioned the informal chats at the reception so I could take part. That is where I met my first collaborator."
