Use Cases

Every situation covered

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

🏛️Large lecture halls

Large lecture halls at ELTE, Semmelweis University, Budapest University of Technology — Hungarian-medium instruction at academic pace. Captio AI captions the professor in real time.

🔬Seminars and tutorials

Seminars and szeminárium sessions where discussion is in Hungarian, often switching to English for terminology. Captio AI handles both languages without manual adjustment.

💻Online and recorded lectures

Recorded lectures on university portals or shared as video files — play on speaker and Captio AI captions whatever is playing in real time.

📚Study groups

Study groups in Budapest student accommodation reviewing Hungarian lecture content. Captio AI captions whoever is speaking.

🌍Foreign-language and international courses

Lectures from Transylvanian or Vojvodinian faculty whose Hungarian carries regional phonological features. Captio AI handles regional accented Hungarian.

🎤Guest speakers and public talks

Online courses and webinars delivered by Hungarian universities. Captio AI captions any audio source in real time.

Why Captio AI

Built for the pace and pressure of a real lecture

Follow without splitting your attention

Lip-reading and note-taking at the same time is an impossible cognitive load. Captio AI handles the following so you can direct all your attention to understanding what is being said.

Captions while the lecturer is still speaking

Words appear on your screen as they are said — not after the sentence ends. You stay in sync with the lecture rather than always being a beat behind.

Works in any lecture setting

Lecture halls, seminar rooms, online classes, study groups. Place the phone on your desk, point it toward the audio source, and Captio AI handles the rest.

A full transcript to study from

Record the lecture and upload it to Audio Transcription after class. Get a complete written record you can search, annotate, and revise from — at your own pace.

60+ languages

For international students, students studying abroad, or courses taught in a second language. Captio AI captions or translates in real time with no manual setup.

No advance notice needed

Official university captioning requires booking in advance and is not available for every session. Captio AI works for any lecture, any time, with no prior arrangement.

Hungarian

Why Hungarian is hard to understand

Long vowel invisibility

  • Hungarian short and long vowels look identical on the lips — but change meaning
  • Hungarian has seven short vowels and seven corresponding long vowels — 'kor' (age) versus 'kór' (disease), 'hal' (fish) versus 'hál' (sleeps). Vowel length is a purely acoustic distinction with no visual correlate. In a Budapest lecture hall, an academic delivering Hungarian at full pace produces no visible difference between short and long vowels throughout the lecture.

Gemination

  • Hungarian double consonants are a meaning-bearing distinction — invisible on the lips
  • Hungarian uses consonant gemination phonemically — 'hal' (fish) versus 'hall' (hears), 'megy' (goes) versus 'meggy' (sour cherry). The distinction is in consonant duration, which is an acoustic property with no visual counterpart. A deaf student watching Hungarian lip movements cannot distinguish single from double consonants anywhere in the lecture.

Morphological density

  • Hungarian suffixes create long words that compress into single continuous lip movements
  • Hungarian words with case suffixes, possessive suffixes, and verbal aspect markers can reach 10–14 syllables. In a lecture, these long morphological chains are delivered at academic pace — the suffix boundaries that carry grammatical meaning compress into continuous articulation with no clear break between the root and its meaning-carrying endings.

Transylvanian-Budapest divergence

  • Hungarian spoken in Romania, Serbia, and Slovakia differs phonologically from Budapest Hungarian
  • Significant Hungarian-speaking communities exist in Transylvania (Romania), Vojvodina (Serbia), and southern Slovakia. Universities in border areas draw students and faculty from both Hungary and neighbouring countries, creating phonological variation across any given lecture hall. A deaf student calibrated to Budapest standard Hungarian finds Transylvanian Hungarian vowel quality and prosody distinctly shifted.

Topic-focus word order

  • Hungarian academic speech uses preverb and verb-final constructions that compress at speed
  • Hungarian marks focus by moving a constituent before the verb, and uses preverb separation and verb-final structures. In fast academic delivery, the verbal complex — preverb plus verb — is often run together with surrounding morphology, producing a cluster of lip positions that carries the lecture's main predicate invisibly.

The Challenge

Hearing loss in Hungary — in a system where sign language recognition came in 2009

The World Health Organization's European Region — which includes Hungary — estimates that 190 million people have disabling hearing loss. Hungary's Hungarian Sign Language (Magyar Jelnyelv) received legal recognition in 2009 under Act CXXV, making it one of the more recent Western European recognitions. SINOSZ, the National Federation of the Deaf and Hard of Hearing in Hungary, represents the country's deaf and hard of hearing community and has campaigned for expanded interpreter services, particularly in healthcare and education.

Hungarian universities do not systematically provide live captioning for deaf and hard of hearing students. Interpreter provision is available in principle but must be arranged individually with the disability office of each institution, interpreter availability is limited, and specialised academic interpreters for technical or scientific fields are scarce. A deaf student at ELTE, Semmelweis, or the Budapest University of Technology attends spoken-only lectures and must self-organise any access to what is said.

The gap between legal recognition of Hungarian Sign Language and practical access in lecture halls mirrors a pattern across Central and Eastern Europe: laws passed, services not scaled. For a deaf student in Budapest attending 20–30 hours of lectures per week, Captio AI provides immediate, no-arrangement access to every lecture in real time — at ELTE's main campus or in a BUTE engineering seminar — without exhausting an annual interpreter allocation in the first month.

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.
