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 Kempegowda International Airport (BLR) in Bengaluru come in Kannada and English. Captio AI captions both languages so you catch gate numbers and boarding times without missing a departure.

🚂Train stations and public transport

KSRTC buses between Bengaluru, Mysuru, Mangaluru, and Hubballi announce destinations in Kannada. At Krantivira Sangolli Rayanna railway station in Bengaluru, Captio AI captions the platform exchange and PA announcement in real time.

🏨Hotels and check-in

A hotel receptionist in Bengaluru or Mysuru explaining room details and local tips in Kannada. Place Captio AI on the counter and follow the full check-in conversation without asking for anything repeated.

🗺️Navigating and asking for help

Asking for directions near Bengaluru's Lalbagh Botanical Garden or navigating the Mysore Palace area on foot. Fast Kannada from locals and auto-rickshaw drivers — Captio AI captions their reply so you find your way.

🛃Customs and immigration

Karnataka customs and immigration at Kempegowda International involve formal Kannada and English. Captio AI captions every question from the officer so you respond accurately and confidently.

🎭Tours and activities

A guide at Mysore Palace, the Hoysala temples at Belur and Halebidu, or Hampi's Vijayanagara ruins delivering Kannada commentary on Karnataka's royal 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.

Kannada

Why Kannada is hard to understand

Four-way stop contrast

  • Voiceless/voiced and unaspirated/aspirated pairs at multiple places — all on the lips
  • Kannada distinguishes voiceless/voiced × unaspirated/aspirated stop pairs at bilabial, dental, retroflex, palatal, and velar positions. At Kempegowda International Airport in Bengaluru or a hotel desk in Mysuru, a check-in agent's use of aspirated vs unaspirated retroflex stops — ಟ (ṭ) vs ಠ (ṭh) — produces movements at the tongue tip that are completely invisible from the front. A deaf traveler watches identical external articulation for phonemically distinct sounds used throughout Kannada travel vocabulary.

Phonemic vowel length

  • Short and long vowel pairs differ only in duration — no visible lip shape change
  • Kannada has short and long vowel pairs (a/ā, i/ī, u/ū, e/ē, o/ō) where vowel length alone distinguishes words. At a bus stand in Bengaluru or a ticket window at Mysore Station, the difference between word pairs is a duration change in the vowel — not a change in lip shape, jaw position, or any visually observable feature. A deaf traveler lip-reading a Kannada station agent or hotel receptionist gets the vowel quality but never the length.

Hasanaga vs North Karnataka vs Coastal dialects

  • Karnataka's dialect regions have different vowels and speech rhythms
  • Kannada has significant dialect variation: Hasanaga dialect (Hassan area), Dharwad/North Karnataka dialect, Coastal Karnataka (Mangaluru) dialect, and southern Mysuru-area speech. Standard Bengaluru Kannada differs from Mangaluru Coastal Kannada in vowel quality, consonant realizations, and pace. A deaf traveler calibrated to Bengaluru speech arrives at Mangalore International Airport to find different articulations at the welcome desk without visual warning.

Tulu and Kannada switching in coastal Karnataka

  • Mangaluru area staff may switch between Kannada and Tulu mid-sentence
  • The coastal belt of Karnataka — Mangaluru, Udupi — is Tulu-speaking territory alongside Kannada. Tulu and Kannada are separate Dravidian languages with different phonological inventories. A deaf traveler at Mangalore International Airport or a hotel in coastal Karnataka may encounter staff switching from Kannada to Tulu without visual signal — two unrelated phonological systems arriving in the same conversation.

Bengaluru Kannada-English switching

  • Bengaluru's tech-city speech switches from Kannada to English mid-sentence
  • In Bengaluru's urban tech environment — hotel desks in Indiranagar, airport lounges at KIA, and tech-park shuttles — Kannada speakers switch into English continuously. The switch from Kannada to English arrives mid-sentence without any visual signal. A deaf traveler reading Kannada phoneme-to-lip mappings suddenly needs to apply English phoneme mappings — without any transition moment their lip-reading can prepare for.

The Challenge

Hearing loss and travel accessibility in Karnataka

Hearing disability is the second most common disability in India, affecting approximately 63 million people nationally — 6.3% of the population — with the National Medical Journal of India reporting an estimated 291 persons with severe-to-profound hearing loss per 100,000 population. Karnataka, with a population of approximately 66 million, carries a proportional share of this burden. Karnataka's National Programme for the Prevention and Control of Deafness (NPPCD) — implemented through the National Health Mission Karnataka — covers district-level hearing screening and early intervention, but access to audiological rehabilitation services is uneven across the state's rural districts and remote areas.

Bengaluru is one of Asia's fastest-growing metropolitan areas and a major hub for both domestic and international travel in India. Kempegowda International Airport (BLR) handles over 36 million passengers annually and is a primary connection point for South India. Karnataka's tourist infrastructure — Mysore Palace, the Hoysala temple circuit at Belur and Halebidu, Hampi's Vijayanagara ruins, Coorg, and the Kabini wildlife reserve — is primarily verbally guided, with no standard real-time captioning infrastructure. For deaf and hard of hearing travelers, a day trip from Bengaluru to Mysore on KSRTC or a guided tour of Hampi involves repeated verbal-only information delivery with no accessible alternative.

Captio AI captions Kannada in real time — whether a boarding call at Kempegowda International, a platform announcement at Mysore Station, or a guide at Hampi's Virupaksha Temple — so a deaf traveler in Karnataka follows every instruction and announcement without depending on audio infrastructure built without them in mind.

People love Captio AI

"BLR gate announcements mix Kannada and English and the PA echo is terrible. I pointed Captio AI at the gate speaker and the boarding call appeared on screen word by word. I've stopped arriving at the gate early just to ask staff if boarding has started."

Hard of hearing, Bengaluru — frequent flier at BLR

"The KSRTC ticket counter in Mysuru is always busy and the agent speaks fast Kannada. I held Captio AI toward the counter and the departure time and bus number appeared immediately. I got the right bus to Coorg on the first attempt."

Deaf, Mysuru — domestic traveler

"Mangaluru airport staff speak Coastal Kannada and sometimes switch to Tulu. I used Captio AI at the check-in desk and followed the baggage allowance conversation completely — no misunderstanding, no extra charges."

Severely deaf, Mangaluru — traveler

"The guide at Hampi spoke fast Kannada with some North Karnataka dialect. I got nothing from watching his face. Captio AI captioned the entire history of the Vijayanagara Empire in real time. I followed every temple, every battle, every king."
