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.

Spanish

Why Spanish is hard to understand

Speed

  • One of the fastest spoken languages on the planet
  • Spanish is among the highest-syllable-rate languages in the world — speakers produce around 7.8 syllables per second in natural conversation. At a check-in counter or airline gate, this means a single sentence about your seat or boarding zone arrives and disappears before a deaf traveler can segment it visually.

Syllable-final deletion

  • Caribbean Spanish drops the ends of words
  • In Dominican, Cuban, and Puerto Rican Spanish, word-final consonants disappear in natural speech. 'Las casas' becomes 'lah casah', 'buenos días' becomes 'buenoh díah'. A deaf traveler lip-reading a Havana customs officer or a Dominican airline worker encounters spoken words whose endings simply do not appear on the lips.

Dialect variation

  • Spain, Mexico, Argentina — each sounds different
  • The seseo-ceceo distinction, Buenos Aires' Italian-influenced prosody, and the aspirated-h of Andalusian Spanish all create distinct lip shapes for the same words. A traveler calibrated to Castilian finds Rioplatense or Mexican border Spanish requires a full re-calibration at every new country.

Rhotics and laterals

  • Rolled r and merged ll/y invisible on lips
  • The distinction between the tapped /ɾ/ and rolled /r/ in Spanish, and the yeísmo merger of ll/y, produce sounds that are either invisible or identical on the lips. A gate announcement with 'embarque' or a hotel key instruction with 'llaves' — the key consonants are unreadable without audio.

Formal vs. colloquial register

  • Announcement Spanish vs. street Spanish
  • Airport PA announcements in Spain and Latin America use a formal, abbreviated register that differs sharply from the conversational Spanish of hotel staff, taxi drivers, and market vendors. A deaf traveler must lip-read across both registers — careful announcement language and fast colloquial speech — often within the same trip.

The Challenge

Hearing loss and travel accessibility across the Spanish-speaking world

In Spain alone, the National Statistics Institute estimates 1,064,000 people are deaf or have a hearing disability — around 2.3% of the population. Across Latin America, the genetic burden of hearing loss is significant: congenital hearing loss affects 2–3 in every 1,000 births, and researchers have documented that the region faces severe limitations in molecular genetic diagnosis due to a shortage of resources. An estimated 80% of the 430 million people globally with disabling hearing loss live in low- and middle-income countries — a category that covers most of Latin America, where travel infrastructure accessibility is least developed.

Travel infrastructure across Spain and Latin America is built around spoken audio. In Mexico, Colombia, Argentina, and Chile, airport PA systems and train station announcements are delivered in Spanish with no standardised real-time visual captioning. Spain's CNSE (National Confederation of Deaf People) has consistently documented access gaps in transport and public service settings. A deaf Spanish-speaking traveler navigating a regional airport in Peru or a busy terminal in Barcelona faces the same structural gap: a system that announces everything by sound.

Captio AI captions Spanish speech in real time — whether a gate PA in Buenos Aires, a customs officer at the Mexican border, or a hotel receptionist in Madrid — so a deaf traveler across the Spanish-speaking world follows every instruction and exchange without depending on a system that does not yet reliably serve them.

Privacy

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.

"Rioplatense Spanish has its own rhythms that I was not calibrated to. Hotel staff, tour guides, the Buenos Aires Subte announcements — Captio AI read all of them. For the first time I felt like a real traveler, not someone guessing at the margins."
