Use Cases

Every situation covered

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

🍽️Dinner with friends

Dinner with friends at a traditional Dutch eetcafé or neighbourhood restaurant, where the conversation moves fast around the table and the background noise of a busy evening crowd competes with what people are saying.

💼Business lunches

Business lunches in Amsterdam's Zuidas or Rotterdam's business centre, where Dutch and English mix across the table and following client conversation in a busy restaurant matters.

Cafe catch-ups

Café catch-ups at a Dutch bruin café or modern coffee bar, where the clink of glasses and nearby conversations compete with the person sitting across from you.

🌍Restaurants abroad

Eating out in the Netherlands as a visitor, where Dutch menus and the server's explanation of daily specials arrive in fast Standard Dutch that takes practice to follow.

🎂Celebrations and group meals

Family celebrations at a Dutch restaurant — birthdays, anniversaries, Sinterklaas dinners — where multiple conversations happen at once and background music fills the room.

❤️Dates and one-on-one meals

Dates at a quiet Amsterdam canal-side restaurant or a Rotterdam rooftop bar where you want to follow every word without asking your partner to repeat themselves.

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.

Dutch

Why Dutch is hard to understand

Final devoicing

  • Word endings lose their contrast
  • Dutch devoices all voiced obstruents at word endings — /d/ becomes /t/, /z/ becomes /s/ — removing the contrast that distinguishes many common words in careful speech. In fast restaurant conversation, this final devoicing compounds with reduction, leaving a deaf diner with fewer distinguishing cues than even standard Dutch would provide.

Schwa-heavy elision

  • Unstressed syllables disappear
  • Dutch reduces unstressed syllables to schwa /ə/ in casual conversation and often deletes them entirely. Phrases like 'heb je' become 'bje' at speed. At a busy Amsterdam or Rotterdam restaurant table, this reduction makes Dutch sound like a blur of schwas punctuated by stressed content words.

Velar fricatives /x/ and /ɣ/

  • The 'harsh g' is produced in the throat
  • The voiced and voiceless velar fricatives — the characteristic Dutch 'g' sound in words like goed and dag — are produced entirely in the throat and carry no visible lip shape. This sound appears constantly in Dutch restaurant conversation and is completely invisible to a deaf lip-reader.

North-South accent divide

  • Randstad Dutch vs. Flemish
  • Northern Dutch (Amsterdam, Rotterdam, The Hague) and Southern Flemish Belgian Dutch (Antwerp, Ghent) differ substantially in vowel quality, /r/ realization, and the degree of final devoicing. A deaf person accustomed to one variety can struggle significantly with the other at a mixed restaurant table.

Dutch-English code-switching

  • English phrases arrive without warning
  • In Amsterdam's and Rotterdam's modern dining scene, English words and phrases appear constantly in casual conversation. Younger Dutch speakers and international diners switch between Dutch and English mid-sentence, confronting a deaf lip-reader with an entirely different phonological system without any signal.

The Challenge

Hearing loss in the Netherlands: employment, participation, and the daily cost

Research using Dutch national data from 2015 to 2019 found that 61% of people with hearing loss were employed, compared with 68% of typically hearing peers — a gap that translates directly to income, independence, and social participation (PMC12231822). The Netherlands Longitudinal Study on Hearing (NL-SH) has tracked how hearing loss affects daily life across education, employment, and social settings, with findings that have directly informed Dutch Ministry of Public Health, Welfare and Sports policy guidelines (PMC10111885).

Globally, an estimated 1.57 billion people lived with hearing loss in 2019 — one in five people worldwide (GBD 2019, PMC7960691). In the Netherlands, Dutch policy enabled sensory disability care claims between 2015 and 2019, representing a formal recognition of the communication support needs of deaf and hard-of-hearing citizens. Yet despite this framework, everyday public settings — restaurants, cafés, bars — operate almost entirely without captioning infrastructure or interpreter support.

Captio AI captions Dutch conversation in real time — at an Amsterdam eetcafé, a Rotterdam business lunch, or a family birthday dinner — so a deaf person can follow every word from the table without needing an interpreter present.
