Use Cases

Every situation covered

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

🩺GP and primary care visits

At a dom zdravlja (primary health centre) in Belgrade, Novi Sad, or a smaller town, your ljekar explains symptoms and treatment in Serbian. Captio AI captions every word so you follow the full consultation.

🔬Specialist consultations

At a specialist appointment at Klinički centar Srbije or a regional hospital, medical terms arrive in Serbian mixed with Latinate and German-origin vocabulary. Captio AI captions both in real time.

💊Pharmacy conversations

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

🦷Dental appointments

At the stomatolog (dental clinic), the dentist gives instructions during treatment when lip-reading is impossible. Captio AI captions from audio alone so you follow every direction.

🧠Mental health sessions

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

🚑Emergency and urgent care

At the hitna pomoć (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.

Serbian

Why Serbian is hard to understand

Pitch accent system

  • Four tones change meaning but produce no visible lip difference
  • Serbian uses a pitch accent system with four distinct tones: long rising, long falling, short rising, and short falling. These tones are phonemically significant — the same vowel sequence carries different meaning depending on pitch. For a deaf or hard of hearing patient, the four tones are entirely auditory. No change in lip shape distinguishes a long rising from a long falling vowel, making clinical vocabulary built on these contrasts impossible to read on anyone's lips.

Ekavian–Ijekavian gap

  • Doctors from different regions pronounce the same word differently
  • Serbian allows two standard pronunciation systems — Ekavian (used in Serbia proper, based in Belgrade) and Ijekavian (used in Bosnia, Montenegro, and by many Serbian speakers in the diaspora). The yat vowel realises as 'e' in one and 'ije/je' in the other, changing the shape of entire word categories. A deaf patient who lip-reads Ekavian encounters Ijekavian-speaking medical staff producing unfamiliar lip patterns for identical words.

Dual script ambiguity

  • Cyrillic and Latin scripts both appear in clinical settings
  • Serbian is officially written in Cyrillic but Latin script is widely used in everyday contexts including prescriptions, clinic signage, and electronic records. A deaf patient who relies on written backup communication during an appointment may encounter either script — adding cognitive load at a moment of high communicative demand.

German medical vocabulary

  • Austrian-Hungarian clinical tradition left German loanwords in Serbian medicine
  • Centuries of Central European influence embedded German-origin medical terms in Serbian clinical practice. Words like 'špricu' (syringe, from German Spritze), 'flaster' (bandage, from Pflaster), and 'tablete' coexist with Serbian native and Latinate vocabulary. A deaf patient must lip-read across three phonological registers within the same appointment.

Fast casual reduction

  • Informal Serbian speech compresses and elides heavily
  • In conversational post-diagnosis speech, Serbian drops unstressed syllables, reduces vowels, and merges words across boundaries at speed. A doctor who slows down for the formal diagnosis but reverts to natural pace for aftercare instructions produces speech significantly harder to lip-read than the deliberate clinical vocabulary that preceded it.

The Challenge

Hearing loss in Serbia: disability poverty and a system under strain

Serbia has one of the highest rates of disability poverty in the Western Balkans. Official figures from Serbia's Republican Institute for Statistics indicate that people with disabilities have an employment rate of around 20% — one in five — against a general population rate that is significantly higher. For deaf and hard of hearing Serbs, navigating the healthcare system means navigating it in a context where communication support infrastructure is limited, interpreter provision is informal and inconsistently available, and the legal framework for disability rights — though formally aligned with the UN CRPD since Serbia's ratification in 2009 — has not consistently produced accessible clinical settings at the point of care.

The situation of the deaf community in Serbia reflects a broader regional pattern: a small, underfunded Association of the Deaf and Hard of Hearing, limited numbers of sign language interpreters active in clinical and public settings, and a healthcare system where the practical experience of a deaf patient is shaped more by individual goodwill of medical staff than by guaranteed structural support. Serbian Sign Language is recognised in education and social policy contexts, but interpreter availability at healthcare appointments — particularly outside Belgrade — is inconsistent.

The toll of this gap falls most heavily on older deaf Serbs and those in rural or peri-urban areas where the dom zdravlja is the primary and often only healthcare access point. In an environment where medical staff are already stretched, a deaf patient who arrives without an interpreter and without assistive technology must rely on note-passing or family mediation — both of which degrade the completeness and accuracy of clinical communication. Captio AI captions Serbian in real time at any dom zdravlja or klinički centar, so every patient receives their doctor's words directly.

People love Captio AI

"My internista at Klinički centar uses the pitch accent distinctions that I simply cannot detect on anyone's lips. Two words that mean completely different things look identical to me. Captio AI captures the audio and I read exactly what the doctor said."

"My specialist trained in Bosnia and speaks Ijekavian — completely different from the Ekavian I lip-read. Captio AI captions both varieties without any difference. I follow every appointment regardless of where the doctor is from."

"The apoteka in Niš — the pharmacist speaks fast Serbian and explains interactions I always miss. I held up my phone and read the captions as she spoke. For the first time I understood which combination of pills I need to avoid."

"No interpreter was available at the dom zdravlja. My family member had to come and translate, but they miss medical details. Captio AI gives me the doctor's actual words — I don't need to filter through someone else's summary anymore."
