Use Cases

Every situation covered

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

🎤Keynotes and main stage talks

From a far seat in a keynote hall at the Zagreb Fair, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Croatian keynote from any seat.

🔬Academic and research conferences

At an academic conference — a research congress at a Zagreb university or a scientific meeting in Split — presenters speak fast and mix in terminology. Captio AI captions in real time and transcribes for later review.

💼Industry and professional events

Industry events, technology and tourism summits, and product launches in Zagreb carry content that affects your work. Captio AI captions every speaker so you follow the panel.

📋Workshops and breakout sessions

In a workshop or breakout, several voices contribute in Croatian from around the table. Place Captio AI on the table and follow every contribution, including from the back of the room.

🤝Networking and informal sessions

The most useful conversations often happen over coffee breaks and at the conference dinner. Captio AI works in these noisy, informal settings the same way it does in the main hall.

🌍International and multilingual events

At an international conference in Croatia, sessions switch between Croatian and English. Live Translator captions foreign-language talks in real time so you follow the full programme.

Why Captio AI

Built for the room where you cannot ask anyone to repeat

Live captions from any seat

Point the phone toward the nearest PA output or speaker. Captio AI captions whoever is presenting in real time — from the front row or the back of a large conference hall.

Works without venue infrastructure

No hearing loop, no captioning service, no advance booking required. Captio AI works independently via microphone — whether or not the venue has provided any accessibility infrastructure.

Covers what official captioning does not

Official captioning, where it exists, typically covers the main stage only. Q&A sessions, workshops, breakouts, and networking are usually left uncaptioned. Captio AI covers all of it.

Record and review after

Record any session and upload it to Audio Transcription for a full written record. Use AI Summary to extract key takeaways — useful for dense technical content you want to process at your own pace.

60+ languages

For international conferences, foreign-language keynotes, or multilingual panels. Live Translator captions and translates in real time across 60+ languages with no manual switching between speakers.

Works for networking too

The conversations in hallways and at lunch matter as much as the sessions. Captio AI works in any setting — informal, noisy, unstructured — the same way it works in the main hall.

Croatian

Why Croatian is hard to understand

Pitch accent

  • Rising and falling tones the lips cannot show
  • Standard Croatian has a pitch-accent system with rising and falling tones and distinctive vowel length on stressed syllables. These separate words but ride entirely on pitch and duration, with no lip cue. From a distant stage a deaf attendee sees identical mouths for words the accent keeps apart.

Ijekavian reflexes

  • The 'ije' and 'je' sequences that reshape words
  • Standard Croatian is Ijekavian, where the old jat vowel surfaces as ije or je — reshaping common words into longer diphthongal sequences. A deaf attendee finds familiar terms carry unfamiliar vowel shapes on a presenter's lips in a keynote.

Three dialect groups

  • Shtokavian, Kajkavian, and Chakavian differ sharply
  • Croatian spans three dialect groups — Shtokavian, Kajkavian, and Chakavian — that differ so much they can challenge mutual understanding. A conference may bring a Zagreb speaker with Kajkavian colouring and a Dalmatian with Chakavian features to the same panel, so a deaf attendee re-calibrates for each.

Affricates and clusters

  • č and ć, dž and đ, plus dense clusters
  • Croatian contrasts the affricate pairs č/ć and dž/đ, which look nearly identical on the lips, and permits demanding consonant clusters. In a keynote these fine distinctions and compressed clusters leave a deaf attendee with little visual footing.

Croatian–English code-switching

  • Technical English inside Croatian sentences
  • Croatian technology, tourism, and academic speech drops English terms into Croatian sentences constantly, especially in Zagreb. A deaf attendee lip-reading Croatian meets English phonology on the key vocabulary, then returns to Croatian, with no visual signal of the switch.

The Challenge

Hearing loss and professional access in Croatia

In the 2011 census Croatia recorded over 13,000 people with impaired hearing, of whom nearly 2,800 had total or major hearing disability, and the country's association of the deaf and hard of hearing — founded in 1921 — today has around 9,000 members across 23 organisations. Disabling hearing loss rises steeply with age, from around 5% in the mid-40s to over half among those aged 75 and older. Against a European backdrop in which about one in five people has some hearing loss, a substantial professional population lives and works with hearing difficulty.

Zagreb, Split, and the Dalmatian coast host a busy calendar of congresses and events — the academic conferences of their universities, the technology and tourism summits at venues like the Zagreb Fair. These run on spoken Croatian delivered over PA systems, with English woven into technical sessions. Real-time Croatian captioning of keynotes, panels, and Q&A is rarely provided, and where any accessibility exists it does not reach the breakouts and networking where professional value is built.

Captio AI closes that gap. Point the phone toward the PA and read every Croatian keynote and panel answer from any seat, record a dense session for the full transcript, and follow the conversations over a coffee break — so a deaf professional in Zagreb or Split gets the same value from the same conference as everyone in the hall.

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.

"Zagreb tech talks drop English terms into Croatian on every point, delivered fast from a far stage. I caught fragments. Captio AI captioned both from my seat. I read the whole session and knew exactly what the launch meant for my team."

"The pitch accents and the close affricates give me nothing on the lips, and the keynote was fast. Captio AI captioned it accurately and I recorded the session. I followed a full congress talk for the first time."

"Zagreb and Dalmatian speakers use very different dialects, and the panel had both. Captio AI captioned every one and the audience questions. As a panellist I answered what was actually asked instead of guessing."

"Networking over coffee is where the useful conversations happen, and it used to be the part I stepped back from. Captio AI captioned the informal chats at the reception so I could take part. That is where I met my first investor."
