Use Cases

Every situation covered

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

🩺GP and primary care visits

At a perearstikeskus (GP centre) in Tallinn, Tartu, or a smaller vald, your perearst explains symptoms and treatment in Estonian. Captio AI captions every word so you follow the full consultation.

🔬Specialist consultations

At a specialist appointment at Tartu Ülikooli Kliinikum or a regional haigla, medical terminology arrives in formal Estonian. Captio AI captions in real time so you follow every detail.

💊Pharmacy conversations

At the apteek (pharmacy), the proviisor explains dosage and drug interactions quickly. Point your phone toward them and read the instructions as they speak.

🦷Dental appointments

At the hambaarst (dental clinic), the dentist gives instructions during treatment when lip-reading is impossible. Captio AI captions from audio alone.

🧠Mental health sessions

In a session with a psühholoog or psühhiaater, sensitive conversations require full comprehension. Captio AI captions the full session so you engage without gaps.

🚑Emergency and urgent care

At the erakorraline meditsiiniosakond (emergency department), staff speak quickly under pressure. Open Captio AI and read their instructions in real time.

Why Captio AI

Built for the conversations where every word matters

Captions as the doctor speaks

Words appear on screen while the doctor is still talking. You read the diagnosis, drug name, or follow-up instruction at the same moment it is said — not after they have moved on.

Medical terminology handled accurately

Drug names, procedure names, clinical terms. Captio AI handles the vocabulary of a real consultation — not just everyday speech.

Review the appointment after

Record the consultation and upload it to Audio Transcription. Get a full written record of everything said — instructions, dosages, referrals — to review at home and share with a carer if needed.

Works in any clinical setting

Consultation rooms, hospital wards, A&E, dental chairs, pharmacy counters. Place the phone near the speaker and Captio AI captions whoever is talking.

Any language

For foreign-language doctors, specialists abroad, or appointments through an interpreter. Live Translator captions and translates in real time so you follow your diagnosis in the language you understand best.

100% private

Medical conversations are among the most sensitive there are. Captio AI processes audio in real time and discards it immediately. Nothing is recorded, stored, or shared.

Estonian

Why Estonian is hard to understand

Three phonological lengths

  • Estonian has three degrees of vowel and consonant length — unique in Europe
  • Estonian is one of very few languages in the world with a three-way phonological length contrast: short, long, and overlong (Q1, Q2, Q3). 'Lina' (sheet), 'linna' (of the city), and 'linna' (overlong) are distinguished by length alone — and the overlong grade has no parallel in any neighbouring language. For a deaf or hard of hearing patient, all three lengths produce the same lip shape but last different durations — a purely auditory distinction invisible on the speaker's face.

Fourteen grammatical cases

  • Estonian's fourteen cases create many different word forms from the same root
  • Estonian has fourteen grammatical cases, meaning a single medical term may appear in up to fourteen different forms depending on its grammatical role in a sentence. In a clinical consultation, a doctor names a condition, discusses it, and refers to it again — in different cases each time, each with a different ending and a different lip shape. A deaf patient lip-reading Estonian must recognise a clinical term across all the case forms it takes throughout the appointment.

South Estonian (Võro/Seto)

  • South Estonian varieties differ substantially from Standard (North) Estonian
  • South Estonian — including Võro and Seto varieties spoken in southeastern Estonia — is distinct enough from Standard Estonian to be considered by some linguists a separate language. Medical staff from Võru, Põlva, or Valga county may speak with South Estonian phonological features that produce different vowel and consonant shapes from Standard Estonian. A deaf patient lip-reading Standard Estonian encounters South Estonian clinical speech as a substantially different phonological system.

Consonant gradation

  • Estonian consonant gradation alternates consonant forms unpredictably across word forms
  • Like Finnish, Estonian uses consonant gradation — a systematic alternation between strong and weak consonant grades across grammatical forms: 'jalg' (leg) vs 'jala' (of the leg), 'õpik' (textbook) vs 'õpiku'. In clinical speech where medical vocabulary appears in multiple grammatical forms, the same word's consonant changes between forms. A deaf patient lip-reading Estonian sees different lip shapes for the same word depending on its case — making recognition harder across the full span of a consultation.

Russian minority language in healthcare

  • Russian is spoken by a significant minority and appears in some clinical settings
  • Approximately 24% of Estonia's population is Russian-speaking, concentrated in Tallinn and the Ida-Viru region of northeastern Estonia. In healthcare facilities in these areas, medical staff may use Russian alongside Estonian — including for clinical terms where Soviet-era Russian medical vocabulary is still in use. A deaf patient lip-reading Estonian at an appointment in Narva or northeastern Tallinn may find Russian-phonology words appearing without advance notice.

The Challenge

Hearing loss in Estonia: 43,500 people and a community shaped by centuries of deaf education

Estonia has approximately 43,500 deaf and hard of hearing people — around 3.3% of the total population, one of the higher proportions in the EU. The Estonian deaf community has a long history: the first records of deaf education in Estonia date to the seventeenth century, and in 1866 Pastor Ernst Sokolovski established the first deaf school in Vändra, which helped to unify Estonian Sign Language (ESL — Eesti viipekeel). Estonian Sign Language is formally recognised and has an active signing community. The Estonian Association of the Deaf (Eesti Kurdumüte Liit) represents the community and advocates for access across healthcare, education, and public life.

For deaf and hard of hearing Estonians navigating healthcare, the picture is of a well-documented community with formal recognition and active institutions, but with the structural constraints that face all small-country sign language communities: a finite interpreter workforce that cannot cover every clinical appointment on demand. The EU Cohesion Fund has supported specific projects improving services for deaf communities in both Estonia's Baltic neighbours, and Estonia has been screening newborns for hearing impairment. The intersection of Estonian's three-length phonological system and its fourteen grammatical cases makes it among the more linguistically challenging European languages for deaf patients who supplement or replace sign language with lip-reading.

In northeastern Estonia — Narva, Kohtla-Järve — the Russian-speaking minority is the majority population, meaning healthcare appointments in these cities may be conducted in Russian rather than Estonian. For a deaf Estonian who lip-reads Estonian and not Russian, attending a clinic in Narva means navigating a medical appointment in a language they were not trained to read. Captio AI captions Estonian and Russian in real time at any perearstikeskus or haigla across Estonia, so every patient receives their doctor's words directly regardless of which language is being used.

People love Captio AI

"My perearst uses Estonian overlong forms — three lengths for the same vowel and I can see none of them on her lips. Captio AI captures the audio and I read every length distinction in text. I finally understand the nuance in my own appointments."

"Estonian fourteen cases mean the same clinical term looks different every time it appears in the sentence. My cochlear implant helps but not at clinical pace. Captio AI captions all fourteen case forms correctly and I follow every consultation at Kliinikum."

"South Estonian in Võru sounds completely different from Standard Estonian — the vowels and consonants shift. My GP speaks Võro-influenced Estonian. Captio AI captions it correctly and I follow every appointment without the gap I used to have."

"In Narva the doctors speak Russian — I lip-read Estonian, not Russian. I was lost at every appointment. Captio AI captions Russian as well as Estonian. My appointments at the Narva haigla are finally something I can actually follow."
