Use Cases

Every situation covered

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

🍽️Dinner with friends

A dinner in a Tallinn old-town restoran, friends catching up in fast colloquial Estonian while the server moves between Estonian and Russian with different tables.

💼Business lunches

A business lunch in Tallinn where colleagues use formal Estonian but slip in English project terms constantly.

Cafe catch-ups

Coffee in a Tartu kohvik, a weekend favourite, the conversations around you in South Estonian dialect and the barista in standard Estonian.

🌍Restaurants abroad

Ordering in a restaurant in Narva where the menu is in Estonian but most of the conversation around you is Russian.

🎂Celebrations and group meals

A family celebration at a long table, the older generation in formal Estonian and the younger switching to English when they forget a word.

❤️Dates and one-on-one meals

A quiet dinner for two where Q3-length contrasts in softly spoken words make every sentence a guessing game without captions.

Why Captio AI

Built for the table — however noisy the room

Follows the person across the table

Point the microphone toward the person speaking and Captio AI captions them through the background noise. You do not need to face them, watch their lips, or lean in.

Works through restaurant noise

Restaurant noise averages 80 dBA — well above comfortable conversation level. Captio AI is built for these real environments, not quiet controlled rooms.

Place it and forget it

Put the phone on the table between you and the other person, microphone facing them. You glance at it as needed. No adjusting between sentences, no managing the setup.

No asking for repeats during the meal

Every word appears in real time. If you missed something, the caption is there — you do not need to stop the conversation and ask anyone to say it again.

Any language

For restaurants abroad, multilingual dining companions, or waitstaff who speak a different language. Live Translator captions and translates in real time with no manual setup.

Discreet

A phone on a restaurant table is unremarkable. Captio AI runs quietly, the screen faces you, and most dining companions adapt naturally once they understand what it does.

Estonian

Why Estonian is hard to understand

Three-way phonemic quantity

  • Short, long, and overlong look the same
  • Estonian is one of very few languages in the world that contrasts three degrees of vowel and consonant length — short (Q1), long (Q2), and overlong (Q3). These distinctions carry lexical meaning but are entirely invisible on the lips. A deaf diner tracking Estonian conversation can see the same articulation repeated across three different words with three different meanings.

North-South Estonian divide

  • Võro and Seto sound unlike standard Estonian
  • Standard Estonian is based on northern varieties, while southern dialects — Võro and Seto — differ substantially in vowel inventory, consonant inventory, and morphology. A deaf person trained on standard Estonian encountering Võro-influenced speech in a Võru or Põlva restaurant faces a phonological system quite different from what they learned.

Consonant gradation

  • The same word looks different across grammatical forms
  • Estonian, like Finnish, alternates consonants across grammatical forms in ways that mean the visual appearance of a word root shifts depending on grammatical context. In fast restaurant conversation, this means a word can look different in the same exchange depending on its grammatical role.

Colloquial vowel reduction

  • Casual register differs sharply from formal Estonian
  • Colloquial Tallinn Estonian shortens unstressed vowels and deletes word-final /n/ and /s/, making everyday café and restaurant speech look substantially different from formal or broadcast Estonian. A deaf person who learned from careful-speech input may find casual restaurant register confusing.

Estonian-Russian code-switching

  • Russian enters mid-sentence in mixed settings
  • About 25% of Estonia's population speaks Russian as a first language. In Tallinn's mixed-language restaurants and those in Narva and Ida-Viru, Estonian and Russian shift freely at the table — requiring a deaf Estonian speaker to track two phonological systems simultaneously.

The Challenge

Hearing loss in Estonia: small country, consistent barriers

Estonia's population of approximately 1.37 million means its absolute numbers of deaf and hard of hearing people are small by European standards, but the proportion is consistent with regional averages. The GBD 2019 Study found that hearing loss is the fourth leading cause of years lived with disability globally, and in Northern Europe age-related hearing loss is particularly prevalent as populations age. Estonia's 2021 census data indicates a significant share of older residents — the demographic most affected by age-related hearing loss — living outside major urban centres, where audiology services and deaf community support are thinnest.

Estonia's deaf community maintains cultural institutions including the Estonian Association of the Deaf, but the community's relatively small absolute size limits the scale of interpreter provision and accessibility infrastructure. A hard of hearing person in Narva or Ida-Viru faces an additional complexity: the bilingual Estonian-Russian environment of those regions means they must track two phonological systems simultaneously in everyday social settings — a cognitive load that compounds the difficulty of following fast restaurant conversation.

Captio AI captions live Estonian in real time, so any seat at a Tallinn or Tartu restoran means following what's being said — from the first kohv order to the last toast.

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

"Tallinn restaurant conversations mix colloquial Estonian and Russian and the switching used to lose me mid-sentence. Captio AI handles both and I follow the whole dinner now — including the part where my colleague switches to English to make a joke."

Tallinn, profound hearing loss since childhood

"Tartu has a different rhythm from Tallinn Estonian — the kohvik conversations are fast and the South Estonian dialect bleeds in from visitors. Captio AI handles it all without any settings changes."

"In Narva most restaurant conversation is Russian and I'm an Estonian speaker. Captio AI captions Russian too — I ordered dinner without a single awkward moment of asking the server to write things down."

Narva, sensorineural hearing loss

"The Q3-overlong consonants are the first thing I started missing when my hearing declined. Captio AI captures the full three-way length contrast and I follow Estonian dinner conversation properly again."
