Use Cases

Every situation covered

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

🍽️Family dinners

A Greek family dinner — a Christmas Eve gathering, an Easter meal with the whole family, or a Sunday family lunch that stretches into the afternoon.

🎉Social gatherings and parties

A name day celebration or a family party where the living room fills and multiple conversations run simultaneously over mezedes and wine.

Friend catch-ups

A catch-up with old friends over Greek coffee and tiropita, with rapid conversation jumping between topics, people, and opinions.

🌍Multilingual groups

A community gathering at a local parish, cultural association, or neighbourhood committee where announcements are made and everyone responds at once.

👥Community and club meetings

Three generations at a family table — grandparents from a northern or island dialect, parents in standard Athens Greek, grandchildren mixing in English.

🏠Shared living situations

A casual evening at a Greek taverna, a kafeneio, or a friend's terrace where small groups form and conversations flow freely.

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.

Greek

Why Greek is hard to understand

Dental fricatives

  • Theta and delta are produced at the teeth — often concealed
  • Modern Greek has /θ/ (theta) and /ð/ (delta), dental fricatives produced with the tongue at or between the teeth. This position is sometimes visible but is frequently concealed by lip and jaw movements in fast social speech — and easily confused with /f/ and /v/ visually. At a busy family dinner, dental and labiodental fricatives collapse into the same lip pattern.

Cypriot Greek phonology

  • Cypriot Greek preserves medieval sounds standard Greek has lost
  • Cypriot Greek maintains features of Medieval Greek that Modern Standard Greek has dropped: phonemic geminate consonants, distinct /ts/ affricate realizations, and different vowel qualities. A deaf person trained on Athenian Greek encountering Cypriot relatives at the same family gathering faces a substantially different phonological system — not just an accent.

Northern dialect vowel deletion

  • Northern Greek drops unstressed high vowels entirely
  • In Northern Greek dialects (Macedonia, Thrace), unstressed /i/ and /u/ are frequently deleted or strongly reduced. The same word appears with different vowel counts in northern and southern speakers at the same gathering — a northern speaker and an Athens speaker pronounce recognizably different versions of common words, and a deaf person cannot predict which version will appear.

Voicing assimilation

  • Word-boundary consonants change voicing in connected speech
  • Greek applies progressive voicing assimilation at word boundaries: the voicing of a final consonant spreads to the following initial consonant. In fast natural conversation this creates sequences that differ from careful slow-speech pronunciation. A deaf person who has trained on careful isolated words encounters a shifted pattern in animated social speech.

Fast overlapping pace

  • Greek gatherings are famously animated and simultaneous
  • Greek family and social gatherings are characterised by lively, simultaneous conversation — frequent interruptions, overlapping speakers, and raised voices are cultural norms at the dinner table. A deaf person must constantly choose which face to watch, and the chosen face may not be the one currently making the central point.

The Challenge

Hearing loss in Greece: the scale of daily exclusion

It is estimated that between 25,000 and 40,000 people in Greece have significant hearing loss — including both deaf individuals and those with hearing impairment requiring hearing aids or technical support. Despite this, Greece has not established an official national database of registered deaf and hard-of-hearing citizens. Research published in the Archives of Public Health found that people with hearing disabilities in Greece are systematically not included in health policy and planning processes, and that a considerable proportion of deaf and hard-of-hearing adults do not make appropriate use of healthcare services due to communication barriers and difficulties encountered during medical visits.

A cross-sectional study on health-related quality of life among deaf and hard-of-hearing adults in Greece found significant disparities in mental health, social participation, and access to information compared to the general population. Communication challenges in inclusive education settings have been documented extensively, and the gap between formal legal protections and actual community accessibility is wide. Sign language interpretation is available for some formal public contexts but is absent from family social gatherings, community events, and the animated group settings — the taverna table, the family Easter lunch, the kafeneio — where natural Greek conversation is at its fastest and most overlapping.

Captio AI captions Greek conversation in real time on a phone screen — so a deaf family member at an Easter lunch or a multigenerational gathering in Athens, Thessaloniki, or Nicosia can follow every story, debate, and toast as it is spoken, without waiting for someone to relay the conversation.

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.
