Use Cases

Every situation covered

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

🍽️Dinner with friends

Dinner with family in Karnataka — shared bisibelebath, ragi mudde, or a full Udupi thali — is a warm, talkative meal where Kannada runs from the first dish to the last. A hard of hearing person at a Kannada family table needs real-time captions to follow.

💼Business lunches

Business lunches in Bengaluru often mix Kannada and English depending on the colleague. Missing a comment in either language can mean missing the substance of what was said.

Cafe catch-ups

A quick darshini breakfast stop — standing at the counter with coffee and idli — is a daily ritual in Karnataka. Fast orders and brief conversation in rapid Kannada, plus the noise of a busy Bengaluru darshini, add difficulty.

🌍Restaurants abroad

Travelling and eating out across Karnataka — from a Mysuru palace city restaurant to a Dharwad pedha shop — means navigating regional Kannada varieties. Captio AI captions whatever is spoken.

🎂Celebrations and group meals

Group celebrations in Karnataka — Ugadi meals, Dasara gatherings, and family weddings — involve loud, communal Kannada conversation across large tables. Following without captioning means catching only pieces of the celebration.

❤️Dates and one-on-one meals

A one-on-one meal at a quieter Bengaluru restaurant carries the expectation of sustained Kannada or Kannada-English conversation. Missing a sentence — especially when geminate contrasts carry meaning — creates distance that captions prevent.

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.

Kannada

Why Kannada is hard to understand

Geminate affricates

  • Consonant length distinguishes words invisibly
  • Kannada uses geminate affricates — a short /ʧ/ versus a long /ʧʧ/ — as phonemically distinct. This duration distinction carries meaning but is invisible from outside the mouth. Research on Kannada-learning children with hearing impairment found specifically high rates of errors with Kannada affricates — reflecting the real difficulty these sounds present for hard of hearing listeners.

Four-way stop contrast

  • Aspiration and voicing distinctions look the same
  • Kannada distinguishes voiceless unaspirated, voiceless aspirated, voiced unaspirated, and voiced aspirated stops — all made with essentially the same lip shape. At a restaurant table in Bengaluru or Mysuru, food names and everyday Kannada words depend on these contrasts.

Dravidian three-position system

  • Dental, alveolar, and retroflex — zero lip difference
  • Kannada distinguishes dental, alveolar, and retroflex consonant series — three positions produced with the tongue tip at different points in the mouth, none of which are visible on the lips. The correct identification of which series was used in a food name changes the word entirely.

Regional dialect variation

  • Dharwad, Mysuru, Havyaka, and coastal Kannada differ
  • Karnataka's regional Kannada varieties include northern Dharwad Kannada, southern Mysuru Kannada, Havyaka Kannada, and varieties influenced by Tulu and Kodava. Each differs in vowel quality, intonation, and some consonant realisations — a hard of hearing person calibrated to Bengaluru standard Kannada reads different lip patterns in Dharwad.

Kannada-English code-switching

  • Bengaluru's tech culture blends both languages
  • In Bengaluru's restaurants — from darshini counters to upscale dining — Kannada and English are blended freely. English tech terms, social vocabulary, and menu items appear mid-Kannada sentence without signal, doubling the phonological load for a deaf or hard of hearing person.

The Challenge

Hearing loss in India: the burden across Karnataka's tables

India has approximately 63 million people with significant hearing impairment — 6.3% of the national population. In Karnataka, 2018 census estimates identified approximately 20,839 children aged 0–6 with hearing impairment — a figure that captures only the youngest cohort and reflects a much larger adult population living with hearing loss across the state. Bengaluru, Karnataka's capital, has a high concentration of audiological services, but access for communities in northern Karnataka (Bidar, Kalburgi) and coastal Karnataka (Mangaluru) remains uneven.

Oralist educational approaches have historically dominated Karnataka's deaf schools, training students in lip-reading and speech while limiting sign language exposure. Research on Kannada-learning children with hearing impairment found specifically high error rates with Kannada affricates — indicating a language-specific phonological challenge that generalised lip-reading training does not address. For adults navigating Bengaluru's vibrant restaurant scene, the combination of background noise, fast Kannada, and code-switching with English creates one of the hardest communication environments in daily life.

Captio AI captions Kannada conversation in real time — whether a server at a Bengaluru darshini recites the morning specials in fast Kannada, or a colleague mentions a key point during a business lunch in the city's tech corridor.

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.

Bengaluru, moderate hearing loss

"Mysuru Kannada has a distinct accent from Bengaluru and I grew up with it. Moving to the city meant lip-reading a slightly different variety. Captio handles both without making me choose."

"Dharwad Kannada is its own variety and the food vocabulary here is different from what they use in Bengaluru. Captio gets the regional words right and I finally follow my family at the table."

"Coastal Karnataka Kannada mixes Tulu and Konkani words into sentences in ways that surprised me. Captio follows the code-switching and I stop guessing which language the word came from."
