Use Cases

Every situation covered

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

✈️Airports and boarding

Gate changes and boarding calls at Amsterdam Schiphol (AMS) or Eindhoven Airport come in Dutch and English. Captio AI captions both languages so you catch gate numbers and boarding times — pointed at the PA speaker or a gate agent.

🚂Train stations and public transport

NS Intercity trains announce stops in Dutch. At Amsterdam Centraal, Rotterdam Centraal, or Utrecht Centraal, Captio AI captions the ticket window exchange and platform PA so you find the right platform and train.

🏨Hotels and check-in

A hotel receptionist in Amsterdam, Rotterdam, or Bruges explaining check-in details and local tips in Dutch. Place Captio AI on the desk and follow the full conversation without asking for anything repeated.

🗺️Navigating and asking for help

Asking for directions near Amsterdam's Rijksmuseum or navigating Rotterdam's tram network. Fast Dutch from locals and GVB tram drivers — Captio AI captions their reply so you find your way.

🛃Customs and immigration

Dutch border control and customs at Schiphol or the Hoek van Holland ferry terminal speak quickly in formal Dutch and English. Captio AI captions every question so you respond accurately.

🎭Tours and activities

A guide at the Rijksmuseum, Anne Frank House, or Keukenhof Gardens delivering Dutch commentary on Golden Age art and Dutch history. Captio AI captions in real time so you follow every detail.

Why Captio AI

Built for a world that announces everything by sound

Captions any spoken exchange in real time

Airport staff, hotel receptionists, taxi drivers, tour guides. Hold the phone toward whoever is speaking and read the captions — in any setting, in any country.

60+ languages — no language barrier

Live Translator captions and translates in real time. They speak their language — you read in yours. For every country, every language, no manual setup between interactions.

Works anywhere with a data connection

Wi-Fi or mobile data. A local SIM or roaming plan keeps Captio AI running in any country — airports, hotels, rural areas, and everywhere in between.

Handles travel environments

Noisy airports, busy stations, echoing hotel lobbies. Captio AI is built for real environments — not quiet controlled rooms. It captions through the ambient noise of travel.

Discreet in any public setting

Hold the phone or place it near the speaker. Captio AI runs quietly and draws no attention — useful in customs, immigration, and any formal travel interaction where discretion matters.

Private by default

Travel conversations — customs declarations, hotel bookings, personal exchanges — are never stored or shared. Audio is processed in real time and discarded immediately.

Dutch

Why Dutch is hard to understand

The Dutch G — velar fricative

  • Dutch's iconic /x/ and /ɣ/ are produced at the back of the throat — invisible on the lips
  • The Dutch voiced and voiceless velar fricatives — /ɣ/ and /x/ (the notorious 'Dutch G') — are produced at the soft palate or uvula with no lip or jaw movement. These sounds appear throughout Dutch vocabulary including common travel words. At Amsterdam Schiphol or Rotterdam Centraal, an agent or station announcer using the Dutch G produces nothing visible on their face that corresponds to the most distinctive phoneme of the Dutch language.

Flemish-Dutch dialect divide

  • Belgian Dutch (Flemish) and Netherlands Dutch differ substantially at every counter
  • Standard Dutch (ABN — Algemeen Beschaafd Nederlands) differs significantly from Flemish Belgian Dutch in vowel system, prosody, and pace. Antwerp Flemish, Ghent Flemish, and Brussels Flemish each have their own accent profiles. A deaf traveler calibrated to Randstad Dutch (Amsterdam, Rotterdam, The Hague) lands at Brussels Airport (BRU) or Bruges railway station and encounters a different phonological landscape from every airline and hotel staff member.

Schwa elision in fast speech

  • Dutch reduces unstressed syllables aggressively — words collapse in natural speech
  • Dutch reduces unstressed syllables to schwa /ə/ in normal conversation and deletes schwas entirely in very fast speech. Common function words disappear almost completely. At Schiphol International or Amsterdam Centraal, a gate agent or ticket counter person speaking at normal Dutch pace delivers speech where unstressed syllables have compressed to near-silence, and a deaf traveler's preparation from slower resources gives no preview of what actually arrives.

Diphthong variation across dialects

  • Dutch diphthongs are realized differently across regions — confusing for lip-readers
  • Standard Dutch diphthongs like /ɛi/, /œy/, /ʌu/ are realized very differently in Amsterdam, Rotterdam, The Hague, and Belgium. The Randstad accent raises and fronts these diphthongs in ways that differ from what textbooks describe. A deaf traveler at a hotel in The Hague or a train counter in Utrecht lip-reads vowels that don't match the canonical Dutch vowel chart they prepared from.

Dutch-English code-switching (Dunglish)

  • Dutch speakers in cities switch to English mid-sentence without visual signal
  • Dutch urban professionals — particularly hotel staff, Schiphol employees, and tour guides in Amsterdam — switch between Dutch and English within sentences (informally called Dunglish). A deaf traveler reading Dutch lip-shapes at an Amsterdam hotel check-in or a Schiphol gate desk must suddenly switch to English phoneme mappings mid-sentence — with no transition signal visible on the speaker's face.

The Challenge

Hearing loss and travel accessibility in the Netherlands

The Netherlands has a well-documented hearing loss burden. EuroTrak surveys — the most comprehensive European hearing health data series — find that the Netherlands sits among the mid-range European countries for self-reported hearing loss, at approximately 16–17% of the adult population. Across Europe, the EHIMA (2024) analysis reports that 36% of people with self-reported hearing loss across 30 countries have adopted hearing aids — leaving the majority navigating daily life without amplification. In the Netherlands specifically, earlier estimates placed the number of people with severe hearing loss at approximately 11,400 in a population of 15.5 million, but this figure significantly undercounts the full spectrum of hearing difficulty.

The Netherlands' travel infrastructure — including Schiphol (the fourth busiest airport in Europe, handling over 71 million passengers in 2023), the NS rail network serving 400 stations, and the GVB tram and metro networks in Amsterdam — communicates critical information through spoken Dutch PA announcements. Real-time captioning is not standard at Dutch stations or airports. Amsterdam's major tourist attractions — the Rijksmuseum, the Anne Frank House, Keukenhof — offer audio guides and written materials but not real-time captioning for guided tours. For a deaf or hard of hearing traveler, Schiphol's multi-terminal complexity and frequent gate changes are navigated through audio-only announcements.

Captio AI captions Dutch in real time — whether a gate announcement at Schiphol, an NS station platform change at Utrecht Centraal, or a guide at the Rijksmuseum — so a deaf traveler in the Netherlands follows every instruction and announcement without depending on audio infrastructure built without them in mind.

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.

Reviews

People love Captio AI

"Schiphol gate changes come in Dutch first, then English, and the PA echo is bad. I pointed Captio AI at the speaker and the gate number appeared before half the waiting area had noticed the announcement. First time I've beaten hearing passengers to a gate change."

Hard of hearing, Amsterdam — frequent Schiphol traveler

"Flemish Dutch at Bruges station is very different from Randstad Dutch and most tools fail me there. Captio AI handled the NS ticket counter agent at Rotterdam Centraal and the NMBS agent in Bruges. Both accurate."

"The train from Rotterdam Centraal to Schiphol has fast Dutch PA announcements. I held Captio AI at the speaker for each station and read every announcement correctly. I've stopped standing by the door to watch the platform signs."

Severely deaf, Rotterdam — business traveler

"The guide at the Rijksmuseum gave the Rembrandt overview in Dutch. Captio AI captioned the whole thing — the composition of The Night Watch, the guild history, the pigments. I came out knowing more than the hearing tourists next to me."
