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.

Marathi

Why Marathi is hard to understand

Four-way consonant contrast

  • Voicing and aspiration invisible on the lips
  • Marathi has a four-way contrast in stops: voiceless unaspirated, voiceless aspirated, voiced unaspirated, and voiced aspirated. At a Mumbai railway counter or an airport check-in desk, the aspiration and voicing distinctions that separate words in Marathi are almost entirely acoustic — they produce no visible lip-level difference that a deaf traveler can read.

Retroflex consonants

  • Tongue-back sounds invisible at the lips
  • Like other Indo-Aryan languages, Marathi uses retroflex consonants /ʈ/, /ɖ/, /ɳ/ produced with the tongue curled back. These are invisible at the lips. At a Pune station or a Mumbai hotel desk, the distinction between dental and retroflex consonants that changes word meaning leaves no trace a deaf traveler can see on the speaker's face.

Nasalized vowels

  • Nasalization carried at the palate, not the lips
  • Marathi uses phonemically distinct nasalized vowels — contrast pairs that differ only in the nasal quality produced at the soft palate. At a hotel reception or a railway ticket window, these vowel distinctions that separate words are invisible on the speaker's lips.

Dialect diversity

  • Varhadi, Kokan, and Khandesh Marathi all differ
  • The Varhadi dialect of Vidarbha, the Kokan Marathi of the coastal region, and the Ahirani of Khandesh each have distinct vowel qualities, prosody, and phonology. A deaf traveler lip-reading a hotel receptionist in Nagpur may find the same Marathi words look different from a ticket clerk in Ratnagiri.

Marathi-Hindi code-switching

  • Mumbai Marathi blends seamlessly with Hindi
  • In Mumbai, Marathi and Hindi mix so freely that the combined register — sometimes called Mumbaiya Hindi — is often indistinguishable from either parent language. At Mumbai's CSIA airport or Central Railway terminals, staff shift between Marathi, Hindi, and English within the same sentence, requiring a deaf traveler to lip-read across three phonological systems.

The Challenge

Hearing loss and travel accessibility in Maharashtra

India carries one of the world's largest hearing loss burdens, with the World Health Organization estimating that 63 million people suffer from a significant auditory loss — around 6.3% of the population. Maharashtra, as India's most populous state and its economic capital, holds a proportionally large share of that number. The country's audiometrist-to-population ratio stands at approximately 1 per 500,000, and the speech therapist-to-deaf population ratio at around 1 per 200 — figures that reflect the severe shortage of diagnostic and rehabilitation infrastructure even in relatively well-resourced states like Maharashtra.

Mumbai's railway network — the lifeline of the city, carrying over 7 million passengers daily — communicates critical information through spoken PA in Marathi, Hindi, and English. Platform changes and departure announcements are delivered by audio with no standardised real-time visual captioning system. At Chhatrapati Shivaji Maharaj International Airport — one of India's busiest — the same audio-first approach applies. For a deaf traveler navigating rush-hour Mumbai Central or a crowded terminal at CSIA, a missed announcement has immediate consequences.

Captio AI captions Marathi speech in real time — whether a Mumbai suburban railway platform announcement, a ticket counter in Pune, or a hotel receptionist in Nagpur — so a deaf traveler in Maharashtra follows every instruction and exchange without relying on infrastructure built without them in mind.

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.
