Why Captio AI

Built for the calls you have been avoiding

Captions as they speak

Words appear on screen word by word while the other person is still talking. You read what they say at the same pace everyone else hears it — no delay, no reconstruction.

Works on any call app

Captio AI does not need to integrate with any platform. Put the call on speaker, point the microphone toward the audio, and read the captions. It works the same way for any app on any device.

No more asking for repeats

Every word is on screen as it is said. If you missed something, glance at the caption rather than interrupting the call — the full sentence is there.

Handles call audio accurately

Compressed phone audio is less clean than in-person speech. Captio AI is built for real-world audio conditions, including the reduced quality of standard phone and VoIP calls.

Any language

For calls with family abroad, international colleagues, or foreign-language customer service. Live Translator captions and translates in real time with no manual setup.

Record and review after

Record any call and upload it to Audio Transcription. Get a full written record of everything said — useful for medical instructions, work decisions, and anything worth having in writing.

Kannada

Why Kannada is hard to understand

Four-series stop system

  • Eight stop contrasts produce four lip shapes
  • Kannada maintains a four-way contrast among stops — unaspirated, aspirated, voiced, and breathy-voiced — at both dental and retroflex positions. On a video call, all four produce near-identical lip closures. A deaf caller loses three out of four phonemic distinctions simultaneously and must guess between words that a hearing caller separates without effort.

Kannada diglossia

  • Formal and spoken Kannada are phonologically distinct
  • Formal written Kannada (shishthabhasha) is phonologically distinct from colloquial spoken Kannada. A phone call from a government office uses vocabulary and pronunciation patterns that differ dramatically from Bengaluru colloquial. The two registers share a script but not the same phone shapes — a deaf caller who has calibrated to one encounters different lip configurations in the other.

Regional dialect breadth

  • Dharwad, Mysuru, and Mangaluru Kannada each sound different
  • Kannada has approximately 20 spoken dialects grouped into Northern, Central, and Southern varieties. Each has different vowel systems and consonant treatments. A family video call connecting Mangaluru and Hubballi involves different prosodic shapes — visible in the speaker's rhythm but absent as useful information on the screen.

Retroflex lateral and nasal

  • Retroflex sounds look identical to dental counterparts on screen
  • Like other Dravidian languages, Kannada has distinct retroflex lateral and nasal consonants. On a video call these look identical to their dental counterparts. The distinction collapses visually even though hearing people track it effortlessly through the auditory channel. Many word pairs are distinguished only by this invisible contrast.

Fast speech compression

  • Bengaluru colloquial Kannada compresses unstressed syllables
  • In Bengaluru colloquial Kannada, unstressed vowels — particularly in particles and suffixes — reduce heavily in fast speech. A word pronounced with four visible syllables in careful reading becomes three at conversational pace. A deaf caller's expectations are misaligned from the first syllable of every word.

The Challenge

Sixty-three million Indians with hearing loss — Kannada speakers in Karnataka face the national burden and a significant rural service gap

Approximately 63 million people in India live with significant auditory impairment — 6.3% of the national population — and hearing disability is the second most common cause of disability in the country. Rural communities bear a disproportionate share: the number of persons with hearing disability per 100,000 is 310 in rural India versus 236 in urban areas. Karnataka, which includes both India's major tech city Bengaluru and large rural populations in its northern and coastal districts, reflects this divide directly. Audiological services in Bengaluru are concentrated in private hospitals and specialist clinics; for Kannada-speaking communities in Dharwad, Bidar, or Mangaluru, access is significantly more limited.

The estimated prevalence of adult-onset hearing loss in India is 7.6% and childhood-onset hearing loss is 2%. India's National Programme for Prevention and Control of Deafness targets early detection and intervention, but Karnataka's implementation mirrors the national pattern — services concentrated in urban centres, with district-level access remaining thin. For Kannada-speaking deaf and hard-of-hearing adults in rural Karnataka, the practical consequence is disproportionate dependence on family members to make phone calls with banks, government offices, and medical providers. The diglossia between formal and colloquial Kannada — already a challenge for hearing listeners crossing registers — is a compounded barrier for someone who cannot hear the difference.

Captio AI captions every Kannada call in real time — so a deaf family member in Bengaluru, Mysuru, or Mangaluru can follow the conversation without asking the caller to slow down.
