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 Stockholmsmässan or a venue in Gothenburg, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Swedish keynote from any seat.

🔬Academic and research conferences

At an academic conference — a research congress at a Stockholm university or a scientific meeting in Lund — 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 summits, and product launches in Stockholm and Gothenburg 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 Swedish 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 fika 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 Sweden, sessions switch between Swedish 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.

Swedish

Why Swedish is hard to understand

Pitch accent

  • Word pairs told apart by pitch, not by the lips
  • Swedish has two contrastive pitch accents on stressed syllables, and the same sequence of sounds can be two different words depending on the pitch pattern. Pitch is carried in the voice, not on the mouth, so a deaf attendee watching a distant keynote speaker gets no visual cue for the accent that fixes the meaning.

Large vowel system

  • Nine vowels, many rounded and close together
  • Swedish has a large vowel inventory — nine qualities, distinguished by length, giving around eighteen phonemes — including front rounded vowels like y, ö, and ä. Many of these look almost identical on the lips, so a deaf attendee cannot tell apart the vowel that changes a technical term.

The sje-sound

  • A hard-to-place sound that varies by region
  • The Swedish sje-sound ranges from a back, almost h-like sound in the north to a more front, sh-like sound in the south and in Finland-Swedish. It has no consistent lip shape, so from an audience seat a deaf attendee cannot read the sound at all, and it appears in common vocabulary.

Regional vowel shifts

  • Scanian, Gotland, and Finland-Swedish differ
  • Swedish dialects shift the vowels — Scanian heavily diphthongises long vowels, Gotland preserves old diphthongs, and Finland-Swedish has its own melody. A deaf attendee calibrated to Stockholm Swedish meets different vowel shapes on speakers from other regions.

Swedish–English code-switching

  • Technical English inside Swedish sentences
  • Swedish professionals, among the most fluent English speakers in the world, drop English terms into Swedish sentences constantly, especially in technology. A deaf attendee lip-reading Swedish meets English phonology on the key vocabulary, then returns to Swedish, with no visual signal of the switch.

The Challenge

Hearing loss and professional access in Sweden

Hearing loss is common in Sweden: national public-health data puts the overall prevalence at around 17% of adults, and over a million people report difficulty following a conversation among several people. Yet treatment lags need — only about 2.4% of the population use a hearing aid, against an estimated 7.7% who would benefit, meaning almost half of those who could use one go without. People with hearing impairment report worse health than those with normal hearing, particularly among younger, actively employed people.

Sweden hosts a dense calendar of congresses and events — the academic conferences of its universities, the technology and industry summits at venues like Stockholmsmässan. These run on spoken Swedish delivered over PA systems, with English heavily woven into technical sessions. Real-time Swedish captioning of keynotes, panels, and Q&A is rarely provided, and where captioning exists it covers the main stage, not the breakouts and networking where professional value is built.

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

Privacy

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.

People love Captio AI

"Stockholm tech talks drop English terms into Swedish 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 all those rounded vowels 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."

"Scanian and Stockholm Swedish shift the vowels differently, and the panel had speakers from all over. Captio AI captioned every one and the audience questions. As a panellist I answered what was actually asked instead of guessing."

"Networking over fika 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."
