Use Cases

Every situation covered

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

👨‍👩‍👧Calls with family and friends

A catch-up call with parents in Pune or grandparents in Nagpur. Fast casual Marathi with regional accents and family shorthand. Captio AI captions everything said, at full conversational speed.

💼Work calls and conference calls

A project meeting run in Marathi with colleagues from a Mumbai office or a video call with a Pune team. Business Marathi with code-switching to English for technical terms. Captio AI keeps pace with both.

🏥Medical and healthcare calls

A callback from a government hospital in Aurangabad or a prescription query at the neighborhood chemist in Marathi. Medical calls use formal vocabulary at speed. Captio AI shows the full message in text.

🏦Banks, utilities, and customer service

A Bank of Maharashtra balance enquiry or an SBI IVR menu in Marathi. Automated menus give you one attempt. Captio AI captions each option before the timeout.

🌍International calls

A call from the Marathi diaspora in the US, UK, or Gulf. Diaspora Marathi carries foreign-language influence on rhythm and vocabulary. Captio AI handles it.

📹Video calls — FaceTime, WhatsApp, Zoom

A WhatsApp family video call with a relative in Konkan or a Zoom call with a Pune team. All video call apps work the same way — put the call on speaker, open Captio AI, read the captions.

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.

Marathi

Why Marathi is hard to understand

Four-series stop collapse

  • Aspiration contrast is entirely acoustic
  • Marathi has four series of stop consonants: unaspirated, aspirated, voiced, and voiced aspirated (क/ख/ग/घ). The aspiration that distinguishes कापूस from खाप is entirely in the burst of air — lips make the same closure shape for all four. On a phone call without hearing, all four series collapse into one.

Schwa deletion in fast speech

  • Words lose their middle vowels at speed
  • Fast spoken Marathi drops the schwa from medial syllables: मला becomes m'la, सगळा becomes sg'ḷa. This vowel deletion changes the syllable count and rhythm of familiar words, making word boundaries harder to identify. A deaf caller tracking syllable shapes loses the anchor points when vowels disappear in rapid speech.

Regional variety gap

  • Pune, Vidarbha, Konkan, and Mumbai Marathi sound different
  • Pune, Nagpur (Vidarbha), Konkan, and Mumbai Marathi differ in vowel quality, prosodic rhythm, and vocabulary. A deaf caller familiar with Pune Marathi may not recognize the phonological shape of Vidarbha Marathi even though both are called Marathi. Regional variation is strongest in family and informal calls — exactly the calls that happen most often.

Retroflex invisibility

  • Dental-retroflex pairs look identical on lips
  • Marathi distinguishes dental and retroflex consonant series (त/ट, द/ड, न/ण, ल/ळ). The retroflex sounds are made with the tongue curled back against the palate — with no visible change at the lips. These contrasts are phonemically meaningful but completely invisible and available only in the acoustic signal.

Nasalized vowel density

  • Marathi nasalization changes meaning but leaves no lip trace
  • Marathi nasalized vowels (अं, आं, इं) are frequent in natural speech and distinguish words. They are produced by lowering the soft palate with no outward mouth change. On a phone call without hearing, the nasalization that differentiates pairs of words is entirely inaudible and invisible simultaneously.

The Challenge

Sixty-three million deaf and hard of hearing people in India — and telephone access built for none of them

India is home to approximately 63 million deaf and hard of hearing people — hearing disability is the second most common disability in the country. A 2022 analysis using National Family Health Survey (NFHS-5) data found disabling hearing loss prevalence ranging from 4.5% to 18.3% in community-based studies, with rural Maharashtra recording higher rates than urban centres. Of hearing-disabled Indians of working age (15–59), 73.9% are classified as marginal workers according to 2011 census data, indicating that telephone-based systems — banking, government schemes, medical callbacks — represent a primary exclusion frontier.

India has no national telephone relay service accessible on mobile or VoIP platforms. Indian Sign Language (ISL) is used in deaf communities across Maharashtra, but interpreters remain scarce outside major cities. Government healthcare callbacks, bank IVR menus, and employer video meetings all assume the recipient can hear — leaving deaf Marathi speakers dependent on a family member to place or receive calls on their behalf.

Captio AI gives a deaf Marathi speaker in Nagpur the ability to follow a hospital appointment callback, navigate an SBI IVR menu, or join a WhatsApp family video call from Konkan in real time — on any phone, without a relay service, without an interpreter on standby.

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.

"Bank of Maharashtra's IVR menu is all in Marathi and I was pressing wrong options because I couldn't hear the announcements. With Captio AI I read each option before the timeout. Fixed something I had been struggling with for years."
