Use Cases

Every situation covered

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

🩺GP and primary care visits

At a huisarts (GP) in Amsterdam, Rotterdam, or a smaller town, your doctor explains symptoms and prescriptions in Dutch. Captio AI captions every word in real time so you follow the full consultation.

🔬Specialist consultations

At a specialist appointment at an academisch ziekenhuis (university hospital) or regional hospital, medical terminology arrives in a mix of Dutch and Latinate clinical vocabulary. Captio AI keeps pace with both.

💊Pharmacy conversations

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

🦷Dental appointments

At a tandarts (dental clinic), the dentist gives instructions during treatment when you cannot see their face. Captio AI captions from audio alone so you follow every direction.

🧠Mental health sessions

In a mental health session with a psycholoog or psychiater, conversations go deep quickly. Captio AI captions the full session so you engage without missing nuance.

🚑Emergency and urgent care

At a spoedeisende hulp (emergency department), staff speak quickly under pressure. Open Captio AI and read their instructions as they arrive.

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.

Dutch

Why Dutch is hard to understand

The G problem

  • The Dutch G is invisible and varies by region
  • Dutch has two distinct realizations of /g/ — the hard northern velar fricative and the soft southern variety — both produced at the back of the throat where lips show nothing. Medical vocabulary is dense with g-initial words (gezondheid, geneesmiddel, gebruik). A deaf patient cannot read the g on anyone's lips regardless of which Dutch region the doctor is from.

Final devoicing

  • Word-final consonants are devoiced in fast speech
  • Dutch devoices voiced consonants at the end of words — 'hond' is pronounced with a final /t/ sound. In connected speech this interacts with liaison, producing unexpected consonant clusters across word boundaries. A deaf patient lip-reading Dutch encounters a phonological system that regularly says one thing and means another at word boundaries.

Schwa reduction

  • Unstressed syllables collapse to schwa and disappear
  • In casual clinical speech, Dutch unstressed syllables reduce heavily to schwa (/ə/) or drop entirely. 'Ik heb het al gezegd' becomes a near-continuous stream. Medical instructions already dense with polysyllabic terminology become even harder to segment when every unstressed syllable is swallowed.

Dialectal register gap

  • Flemish, Zeelandic, and Limburg speech differ markedly
  • Dutch dialects in Belgium (Flemish), Zeeland, and Limburg have distinct vowel realisations and intonation patterns from Standard Dutch. A deaf or hard of hearing patient who learned to lip-read Standard Dutch will find a Belgian Flemish doctor's face producing unfamiliar vowel shapes for the same words.

Medical latinate vocabulary

  • Clinical terms layer Latin-origin words onto Dutch phonology
  • Dutch clinical communication mixes Germanic Dutch with Latinate medical vocabulary. 'Bloedverdunners' versus 'anticoagulantia' — the same drug named two different ways depending on the doctor's register. A deaf patient must parse which register is active and lip-read across the resulting hybrid phonology.

The Challenge

Hearing loss in the Netherlands: recognition and real barriers

Approximately 1.5 million people in the Netherlands live with some degree of hearing loss — roughly one in eleven residents. Around 150,000 people purchase hearing aids every year, and more than a third of the hearing-impaired population use some form of hearing device. Despite this scale, the legal framework protecting deaf people in Dutch society lagged behind many comparable European nations. Nederlandse Gebarentaal (NGT — Dutch Sign Language) was only awarded official legal recognition in October 2020, after decades of lobbying by the deaf community. Before that recognition, Roma, Frisian, and Yiddish had all been legally recognised as minority languages in the Netherlands while NGT had not.

The recognition of NGT in 2020 marked a legal milestone, but formal recognition and practical access are not the same thing. Healthcare settings in the Netherlands still lack consistent, funded interpreter provision for deaf patients. A deaf person attending a huisarts or specialist consultation is not guaranteed access to an NGT interpreter — they may be offered a telephone relay service, a family member's assistance, or simply a slower conversation pace. Research on sign language navigation in the Netherlands has examined how hearing parents of deaf children struggle to access sufficient sign language support, a gap that points to a broader infrastructure deficit in interpreter provision across the country.

In a Dutch clinical context, the combination of a fast-speaking doctor, medical vocabulary that mixes Germanic and Latinate registers, and no guaranteed interpreter means deaf and hard of hearing patients regularly leave appointments with incomplete information. This is not a question of willingness — Dutch healthcare workers frequently want to communicate effectively — but a structural mismatch between what patients need and what the system provides. Captio AI captions Dutch in real time at any huisarts or ziekenhuis, so the patient receives the doctor's words in full without relying on a third party.

"My huisarts in Amsterdam speaks very fast Dutch and drops unstressed syllables entirely. I could catch one word in three. Captio AI captions the whole consultation and I leave knowing my diagnosis and the next steps."

"At Erasmus MC, the cardiologist names everything in Latinate medical terms then explains in colloquial Dutch. My cochlear implant struggles with the switch in register. Captio AI captions both and I follow the full explanation."

"Belgian Dutch sounds different from what I learned to lip-read in the Netherlands. At the hospital in Antwerp I was lost. Captio AI captions Flemish Dutch perfectly — I could finally follow my own specialist appointment."

"The pharmacist at my apotheek runs through drug interactions at full speed. I asked them to slow down and they did for one sentence, then went back to normal pace. Captio AI captions everything in real time — I don't have to ask anyone to repeat themselves."
