Use Cases

Every situation covered

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

👨‍👩‍👧Calls with family and friends

A call home to family in Helsinki, Tampere, or Oulu — catching up in Finnish at the pace of an everyday family phone call.

💼Work calls and conference calls

A work call with Finnish colleagues or clients — standard professional Finnish with sector vocabulary, possibly with background noise from an open-plan office.

🏥Medical and healthcare calls

A callback from a Finnish health centre (terveyskeskus), a hospital, or a pharmacy — healthcare calls where every instruction about medication or a referral must be understood.

🏦Banks, utilities, and customer service

A call from Kela, a bank, a utility company, or a customer service line in Finland — automated Finnish menus followed by an agent speaking at full conversational speed.

🌍International calls

A call from a Finnish relative in Sweden or Norway who mixes Finnish with Swedish mid-conversation.

📹Video calls — FaceTime, WhatsApp, Zoom

A FaceTime or Teams video call with family or Finnish colleagues — the standard platform for remote contact in Finland's widely dispersed population.

Why Captio AI

Built for the calls you have been avoiding

Captions as they speak

Words appear on screen word by word while the other person is still talking. You read what they say at the same pace everyone else hears it — no delay, no reconstruction.

Works on any call app

Captio AI does not need to integrate with any platform. Put the call on speaker, point the microphone toward the audio, and read the captions. It works the same way for any app on any device.

No more asking for repeats

Every word is on screen as it is said. If you missed something, glance at the caption rather than interrupting the call — the full sentence is there.

Handles call audio accurately

Compressed phone audio is less clean than in-person speech. Captio AI is built for real-world audio conditions, including the reduced quality of standard phone and VoIP calls.

Any language

For calls with family abroad, international colleagues, or foreign-language customer service. Live Translator captions and translates in real time with no manual setup.

Record and review after

Record any call and upload it to Audio Transcription. Get a full written record of everything said — useful for medical instructions, work decisions, and anything worth having in writing.

Finnish

Why Finnish is hard to understand

Vowel length

  • Short and long vowels carry different meanings with the same lip shape
  • Finnish distinguishes short and long vowels that change word meaning entirely — 'tuli' (fire), 'tuuli' (wind), 'tulli' (customs). On the lips, the mouth holds the same position; only the duration differs. On a phone call, this distinction is purely auditory.

Geminate consonants

  • Doubled consonants mark meaning with no visible lip change
  • Finnish uses geminate (doubled) consonants to distinguish words — 'tapan' (I kill) vs 'tappan' (I kill repeatedly), 'kato' (crop failure) vs 'katto' (roof). The lip closure for a /p/ or /t/ is the same whether it is single or doubled; only the hold duration differs.

Agglutinative suffix chains

  • Multiple suffixes compress into long unbroken runs
  • Finnish stacks case suffixes, possessive suffixes, and clitics onto a single stem — 'talossanikin' means 'in my house too' in one word. In fast speech these suffix chains compress into long runs with no visible word boundary, making it hard to segment what is being said.

Vowel harmony

  • Suffix vowels shift based on the stem — invisibly
  • Finnish divides vowels into front and back sets, and suffixes must harmonise with the stem. In fast speech the fine distinction between front and back vowels collapses, shifting the expected lip shape and making suffix boundaries ambiguous.

Finland-Swedish code-switching

  • Swedish appears in bilingual regions without warning
  • In Helsinki and along the Swedish-speaking coastal regions, Finnish speakers move between Finnish and Swedish mid-sentence. The phonological shift is seamless and the two languages share similar consonant inventory, making the switch hard to detect visually.

The Challenge

Hearing loss in Finland: strong policy, ongoing gaps

Finland has approximately 750,000 people with some degree of hearing loss out of a population of 5.5 million — applying the Global Burden of Disease 2019 prevalence rates for the European region. Finnish Sign Language (FinSL) is one of the few sign languages protected by a national constitution: it was written into Finland's Constitution Act in 1995, giving it formal recognition decades before most European countries. A population-based cross-sectional study on Finnish older adults (PMC5100231) found that hearing loss was significantly associated with reduced use of preventive health services, a pattern that points to systematic underuse of healthcare among those who cannot follow phone-based communications.

Despite strong policy, a gap persists between legal recognition and practical access. A Finnish register study covering all residents aged 60–99 from 2009 to 2019 (Oxford Academic, Age and Ageing) found that hearing loss substantially raises lifetime risk of comorbid disability — compounding the social isolation that phone and video call inaccessibility creates. Hearing aid uptake in Finland remains incomplete, and even for aided users, calls from unfamiliar speakers, speakers with regional dialects, or calls involving Finnish-Swedish code-switching remain difficult to follow.

Captio AI captions every Finnish phone call in real time — from a family call in Helsinki to a Kela callback in formal Finnish — so deaf and hard of hearing users can follow every word independently.

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.
