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 the Megaron Athens International Conference Centre or a venue in Thessaloniki, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Greek keynote from any seat.

🔬Academic and research conferences

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

💼Industry and professional events

Industry events, shipping and technology summits, and product launches in Athens 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 Greek 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 Greece, sessions switch between Greek 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.

Greek

Why Greek is hard to understand

Dental fricatives

  • The θ and δ sounds with almost no visible movement
  • Greek relies on θ (as in 'thin') and δ (as in 'this'), made with the tongue between the teeth and producing very little visible lip movement. These are core Greek sounds that appear throughout academic vocabulary, so from a distant stage a deaf attendee misses exactly the sounds that carry a technical term.

Velar fricatives

  • The χ and γ sounds made at the back of the mouth
  • Greek has the fricatives χ and γ, produced far back in the mouth with no lip cue. In a keynote these give a lip-reader nothing to work with, yet they distinguish common words and appear in scientific terminology.

Mobile stress

  • Stress that moves and changes meaning
  • Modern Greek has variable, meaning-bearing stress that moves between forms of a word. A deaf attendee trying to anchor a word by its stressed syllable finds the anchor shifts as the speaker inflects it through a technical argument, with the stress carried in pitch, not on the lips.

Cypriot dialect

  • Mainland and Cypriot Greek differ on the podium
  • A Greek-language conference may bring mainland and Cypriot Greek speakers together. Cypriot Greek has consonant gemination and unique diphthongs the mainland lacks, so a deaf attendee calibrated to Athenian Greek meets different shapes on a Cypriot presenter's lips.

Greek–English code-switching

  • Technical English inside Greek sentences
  • Greek academic and technology speech drops English terms into Greek sentences constantly, especially in science and business. A deaf attendee lip-reading Greek meets English phonology on the key vocabulary, then returns to Greek, with no visual signal of the switch.

The Challenge

Hearing loss and professional access in Greece

Greece gathers comparatively little national data on hearing loss, which itself is part of the problem: researchers have found that deaf and hard of hearing Greeks are systematically left out of health policy and planning, with probable under-diagnosis and under-treatment and measurably poorer health-related quality of life than the general population. Against a European backdrop in which around one in five people has some hearing loss, a substantial professional population lives and works with hearing difficulty that the system barely counts.

Athens and Thessaloniki host a busy calendar of congresses and events — the academic conferences of their universities, the shipping and technology summits of a major maritime economy, the business events at venues like the Megaron Athens International Conference Centre. These run on spoken Greek delivered over PA systems, with English woven into technical sessions. Real-time Greek 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 Greek 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 Athens or Thessaloniki 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.

"Mainland and Cypriot Greek differ on the lips, and the panel had both. Captio AI captioned every speaker and the audience questions from the floor. 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 investor."
