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.

Estonian

Why Estonian is hard to understand

Three-degree quantity

  • Short, long, and overlong — a three-way distinction invisible on the lips
  • Estonian is one of very few languages with a ternary phonological quantity system — Q1 (short), Q2 (long), and Q3 (overlong) — in both vowels and consonants. Minimal pairs distinguished only by quantity degree produce no visible lip movement difference. In a meeting, a deaf attendee cannot recover these contrasts by watching the speaker's mouth.

Vowel inventory

  • 9 vowels and 36 diphthongs create a complex acoustic landscape
  • Estonian has 9 vowel phonemes and 36 diphthongs — 28 of which are native to the language. In fast corporate speech, diphthong quality distinctions reduce and monophthongs converge. For a deaf professional in a Tallinn meeting, vowel-dependent word distinctions that are clear in deliberate speech blur at meeting pace.

South Estonian gap

  • South Estonian (Võro/Seto) is effectively a separate language
  • South Estonian — particularly Võro and Seto — is widely considered a separate Finnic language rather than a dialect of Estonian. In a meeting with a colleague from the Võrumaa or Setomaa region who uses Southern features in informal speech, the phonological departure from standard Estonian is substantial enough to disrupt comprehension entirely.

Vowel harmony loss

  • Unexpected front-back vowel combinations arise from lost harmony
  • Unlike Finnish, Estonian has lost its strict vowel harmony, leaving forms where front and back vowels coexist in ways that violate listener expectations. In fast meeting speech, these unexpected vowel sequences in loanwords and inflected forms create acoustic patterns that a deaf attendee does not anticipate.

English code-switching

  • Estonian tech and startup meetings are heavily English-integrated
  • Estonia's globally recognised e-governance, fintech, and startup culture means that professional meetings routinely mix Estonian and English — sometimes with English as the dominant language even in all-Estonian teams. The switch between Estonian and English phonology in the same sentence demands constant recalibration from a deaf attendee.

The Challenge

Hearing loss and workplace exclusion in Estonia

Estonia, with a population of approximately 1.3 million, has an active deaf community represented by the Estonian Association of the Deaf and recognised by the European Union of the Deaf. The GBD 2019 study (The Lancet / PMC7960691) estimates global hearing loss prevalence at approximately one in five people — a rate that suggests roughly 260,000 Estonians living with some degree of hearing difficulty. Estonia's advanced digital infrastructure has facilitated some accessibility gains in public services, but real-time workplace meeting accessibility remains largely unstructured.

The WHO's global hearing loss data (WHO fact sheet, 2023) documents that hearing loss affects professional participation disproportionately in all countries, reducing employment rates, income, and career progression. Estonia's internationally integrated tech and startup economy — where English and Estonian are both used as professional languages — creates an environment where deaf professionals must track two phonological systems simultaneously in the same meeting. Estonian Sign Language is recognised, but interpreter provision for corporate meetings is limited, particularly in smaller companies outside Tallinn.

Estonia's ternary quantity system — the three-degree vowel and consonant length contrast — is one of the most distinctive and acoustically demanding phonological features in any European language. It is entirely invisible on the lips, entirely inaudible with significant hearing loss, and outside the training data of most generic captioning tools. For a deaf professional in a Tallinn fintech, a Tartu university meeting, or a Narva manufacturing briefing, real-time Estonian captions are the only reliable access tool. Captio AI provides those captions on a personal device, without interpreter scheduling or institutional infrastructure.
