Why Captio AI

Built for the speed of a real meeting

Captions while they are still speaking

Words appear on screen as each person talks — not after they finish. You read what someone is saying at the same moment everyone else hears it.

Works in any meeting format

Conference rooms, open-plan offices, video calls, all-hands. Place the phone on the table or hold it — Captio AI handles the rest.

Handles fast speech and crosstalk

Captio AI is designed for real meetings, not controlled dictation. It follows whoever is speaking loudest at any moment, keeping up with the natural pace of discussion.

No setup, no explaining

Open the app and place the phone. No pairing, no telling colleagues what you are doing, no requesting anything from the meeting organiser.

Review everything after

Record the meeting and upload it to Audio Transcription for a full written record. Use AI Summary to extract decisions and action items so nothing from the meeting gets lost.

60+ languages

For international teams, multilingual meetings, or colleagues who switch between languages mid-discussion. No setup required — Captio AI detects and captions in real time.

Greek

Why Greek is hard to understand

Stress ambiguity

  • Greek stress marks are invisible on the lips in spoken language, making stress-position ambiguity systematic across every meeting sentence
  • Modern Greek uses a single tonic accent that marks which syllable carries primary stress. At meeting pace, the stressed syllable is acoustically louder and longer — but on the lips, the difference between a stressed and unstressed syllable is minimal. A deaf person lip-reading Greek encounters systematic stress-position ambiguity for every multisyllabic word in a meeting, which translates to word-level misidentification.

Cypriot gemination

  • Cypriot Greek geminates consonants that Standard Modern Greek eliminated — creating a phonological gap between meeting participants from different regions
  • Cypriot Greek retains geminate consonants that Standard Modern Greek dropped — the same word has a longer consonant hold in Cypriot that creates a different rhythmic pattern on the lips. In a meeting with a Cypriot participant, these geminates produce duration patterns that a deaf lip-reader familiar with Standard Greek will not recognise — creating systematic word misidentification.

Fast speech reduction

  • Fast Athenian Greek drops syllables and merges adjacent vowels at meeting pace in ways invisible to lip-reading
  • Casual Athenian Greek at meeting speed undergoes significant vowel coalescence and consonant elision at word boundaries. Adjacent vowels merge, unstressed syllables drop, and word boundaries collapse into a continuous flow. For a deaf or hard of hearing person, this removes the visual distinctiveness of word boundaries, making sentence segmentation from lip-reading very difficult.

Formal vs demotic register gap

  • The gap between formal katharevousa-influenced executive register and everyday demotic Greek creates two distinct phonological profiles in a single meeting
  • Although the formal katharevousa register was abolished officially in 1976, its influence persists in boardroom vocabulary and executive speech. A senior executive uses vocabulary and morphological forms that sound and look different from the demotic Greek used by the same speaker in a corridor conversation. A deaf person lip-reading across these register shifts encounters what sounds like alternating phonological systems in the same meeting.

Greek–English code-switching

  • Greek corporate and tech meetings in Athens integrate English terms mid-sentence, creating unexpected phonological system shifts
  • Greek corporate, startup, and technology sectors integrate English vocabulary heavily. In a Greek meeting at a startup or consulting firm, a sentence may be largely Greek in structure but contain English terms delivered with English phonology for technology, management, and financial concepts. A deaf person lip-reading Greek encounters these English segments as unexpected phonological mismatches.

The Challenge

Hearing loss and workplace exclusion in Greece

Between 40,000 and 60,000 people in Greece rely on Greek Sign Language (GSL) for daily communication, including Deaf individuals and their hearing family members. Greek Sign Language was officially recognised under Law 2817/2000 as the first language of deaf people, with its equivalence to Greek affirmed by Law 4488/2017. However, a cross-sectional study published in BMC Health Services Research (PMC6174559) found that only 9% of DHH adults in Greece had completed tertiary education — a stark indicator of how early-life accessibility gaps compound into adult professional disadvantage.

Disabled people in Greece face unemployment rates three to four times higher than the general population, according to research from the University of Siegen's INsign project on inclusive education. The primary reasons cited are communication problems due to lack of GSL familiarity among colleagues and insufficient recognition of deaf people's professional abilities. GSL interpretation access remains constrained: GSL users have the right to 25 free interpretation hours per year since 2011, after which they must pay significantly elevated rates. For a professional who attends weekly meetings, 25 hours is exhausted in roughly one month.

Greece's maritime, tourism, and services sectors — the country's largest employers — are meeting-intensive environments. The growing tech and BPO presence in Athens adds a Greek–English code-switching layer to meeting accessibility that existing tools do not address. Deaf and hard of hearing professionals navigating Athens's corporate environment face both the linguistic complexity of Modern Greek (with its register variation and rapid connected speech) and an interpreter access system that runs out before the quarter ends.

People love Captio AI

"Athens startup meetings are fast Greek with English terms mixed in — the lip shapes change mid-sentence and I was missing chunks of every discussion. Captio AI captions both languages in real time. I contribute to the meeting now instead of watching it."

"Piraeus shipping meetings use formal Greek vocabulary mixed with fast demotic Greek and I was completely lost. Captio AI gives me the full text in real time. The weekly operations briefing is accessible for the first time in my career."

"Cypriot Greek in a boardroom sounds different from Athenian standard — the geminate consonants create a rhythm that no lip-reading works for. Captio AI handles the Cypriot variety accurately. My board meetings are readable now."
