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 Kyiv or Lviv, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Ukrainian keynote from any seat.

🔬Academic and research conferences

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

💼Industry and professional events

Industry events, IT and technology summits — a major sector in Ukraine — carry content that affects your work directly. Captio AI captions every speaker so you follow the panel.

📋Workshops and breakout sessions

In a workshop or breakout, several voices contribute in Ukrainian 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, sessions switch between Ukrainian 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.

Ukrainian

Why Ukrainian is hard to understand

Palatalization

  • Hard, soft, and half-soft consonants that look alike
  • Ukrainian contrasts plain and palatalized consonants — and has a third 'half-soft' category too. The softening is a tongue-body gesture with barely any visible cue, so from a distant stage a deaf attendee sees the same mouth for consonants that make different words in a keynote.

Sibilant allophony

  • Western speech shifts sibilants before front vowels
  • In western Ukrainian, posterior sibilants shift before high front vowels in a way Kyiv speech does not. A deaf attendee calibrated to standard Ukrainian meets, from a Lviv presenter, different sibilant realisations that further blur already hard-to-read distinctions.

Unstressed centralization

  • Weak vowels drift and blur at speed
  • Ukrainian keeps its vowels fuller than Russian, but in fast speech unstressed vowels drift toward a central quality. In a rapid keynote this centralization softens the vowels that would help a deaf attendee segment a long technical term on the lips.

Consonant clusters

  • Clusters that compress in fast delivery
  • Ukrainian permits demanding consonant clusters that compress further at podium pace. In a fast panel exchange these run together into a stream that offers a lip-reader almost no visual seams between words.

Ukrainian–English code-switching

  • Technical English inside Ukrainian sentences
  • Ukrainian academic and technology talks drop English terms into Ukrainian sentences constantly, especially in the country's large IT sector. A deaf attendee lip-reading Ukrainian meets English phonology on the key vocabulary, then returns to Ukrainian, with no visual signal of the switch.

The Challenge

Hearing loss and professional access in Ukraine

Before the full-scale war, the World Health Organization estimated that more than 2 million people in Ukraine had impaired hearing, with tens of thousands living with complete hearing loss and depending on text and visual alerts for critical information. The Ukrainian Society of the Deaf, founded in 1933, represents a community whose access needs have only grown more urgent under wartime conditions, where sign-language interpreting and captioning services have been stretched and disrupted.

Ukraine has a large and internationally connected professional sector — particularly in IT — and a conference culture centred on Kyiv and Lviv. Academic congresses, technology summits, and industry events run on spoken Ukrainian delivered over PA systems, with English woven into technical sessions. Real-time Ukrainian captioning of keynotes, panels, and Q&A is rarely 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 Ukrainian 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 Kyiv or Lviv 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.

People love Captio AI

"Ukrainian IT talks mix in English terms 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 which announcements mattered for my team."

"The keynote was fast Ukrainian, and the soft consonants and clusters give me nothing on the lips. Captio AI captioned it accurately and I recorded the session for the transcript. I followed a full congress talk for the first time."

"Lviv and Kyiv speakers realise the sibilants differently, 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."

"Networking over coffee 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."
