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.

Slovak

Why Slovak is hard to understand

Rhythmic law compression

  • Slovak's rhythmic law automatically shortens long vowels after long syllables — creating length patterns that differ from spelling in unpredictable ways
  • Slovak's rhythmic law (rytmické krátenie) automatically shortens a long syllable that follows another long syllable. This means that as grammatical suffixes are added to long-vowel roots, the vowel lengths shift in ways that differ from what the written form suggests. A deaf or hard of hearing person who has learned to lip-read Slovak from written forms encounters unexpected vowel durations — a feature unique to Slovak among Slavic languages.

Syllabic /r/ and /l/

  • Slovak syllabic /r/ and /l/ function as vowel nuclei — common words have no written vowel, producing near-empty visual frames on the lips
  • Slovak allows /r/ and /l/ to serve as syllable nuclei: 'vlk' (wolf), 'prst' (finger), 'trh' (market). These consonant-only words produce brief sonorant articulations that look like nothing specific on the lips — a mid-central tongue position with lips open. A deaf person lip-reading these words in a meeting sees an almost empty visual frame for an entire syllable.

Eastern dialect incomprehensibility

  • Eastern Slovak dialects use penultimate word stress — vs initial stress in standard — and are described as incomprehensible to Bratislava speakers
  • Eastern Slovak dialects (Zemplínsky, Šarišský, Spišský) use penultimate stress, while Standard Slovak uses initial stress. This stress shift changes which syllable carries the prominence on the lips. The resulting prosodic mismatch is significant enough that an inhabitant of Bratislava may struggle to understand a colleague from Košice or Prešov. For a deaf lip-reader, this means the rhythmic pattern they have learned is systematically wrong for an Eastern colleague.

Vowel length contrast

  • Slovak phonemic vowel length distinguishes meaning but compresses at meeting pace in ways that remove the distinction from the visual stream
  • Slovak distinguishes short and long vowels throughout the vocabulary. At careful pace, long vowels are visually identifiable by slightly longer lip duration. At meeting pace, this duration difference compresses and disappears — creating systematic vocabulary ambiguity for a deaf or hard of hearing person across every sentence of a Slovak business meeting.

Slovak–Czech–English code-switching

  • Slovak professionals regularly mix Czech and English into Slovak — creating a three-language phonological environment in a single meeting
  • Slovak and Czech are highly mutually intelligible and many Slovak professionals mix Czech vocabulary naturally. Slovak corporate meetings also integrate English management and IT vocabulary. In a Bratislava tech or finance meeting, a sentence may move through Slovak, Czech-origin vocabulary, and English terms — three phonological systems in a single utterance, each requiring a different lip-reading calibration.

The Challenge

Hearing loss and workplace exclusion in Slovakia

There are approximately 15,000 deaf sign language users in Slovakia, supported by only 35 working sign language interpreters, according to the European Union of the Deaf member country profile. Slovak Sign Language (Slovenský posunkový jazyk) received legal recognition in 1995 through Slovakia's Law on the Sign Language of the Deaf — one of the earlier European countries to achieve formal recognition. Slovakia ratified the UN Convention on the Rights of Persons with Disabilities in 2010. However, with 35 interpreters for 15,000 users, the interpreter-to-deaf-population ratio remains critically low, meaning most deaf Slovak professionals attend formal meetings without real-time sign language support.

The Slovak Association of the Deaf (established 1991) has been a full member of the European Union of the Deaf since 2005, providing advocacy and services for the deaf and hard of hearing community. Despite Slovakia's progressive sign language legislation, the gap between legal rights and everyday meeting accessibility is substantial. In Bratislava's growing technology, automotive, and financial sectors — among the most dynamic in Central Europe — meeting formats are verbal, fast, and often multilingual, combining Slovak with Czech and English in ways no existing accessibility tool was designed for.

Slovakia's geographical position — sharing linguistic proximity with Czech Republic and Hungary, and closely integrated into Central European corporate networks — means that meetings frequently include speakers from multiple language backgrounds. The Slovak-Czech mutual intelligibility that makes meetings linguistically fluid for hearing participants creates an additional accessibility challenge for deaf professionals, who may encounter Czech vocabulary delivered with Czech phonology without any visual signal that the language has shifted.
