Designed for the real moments that matter — not just quiet controlled environments.
A call with parents or grandparents in Vijayawada or Hyderabad. Family conversations carry regional accents, fast casual Telugu, and the shorthand of close relationships. Captio AI captions everything said.
A project discussion in Telugu with colleagues from a Hyderabad tech company or a video call with a Vizag team. Business Telugu with English code-switching for technical terms. Captio AI keeps pace with both.
A callback from AIIMS Mangalagiri or a specialist in Nellore. Medical Telugu uses formal vocabulary and clinical terms. Captio AI shows the full message — instructions, prescriptions, follow-up — in text.
An Andhra Pradesh government automated call or a bank IVR menu in Telugu. Automated systems give you one chance. Captio AI captions each option before the timeout.
A call from the Telugu diaspora in the US, UK, or Gulf. Diaspora Telugu carries foreign-language influence on rhythm and vocabulary. Captio AI handles it accurately.
A Google Meet with a Telangana team or a WhatsApp video call with family in Visakhapatnam. All video call apps work the same way — put the call on speaker, open Captio AI, read the captions.

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.
Why Telugu is hard to understand
Geminate consonant invisibility
- Doubled consonants are entirely internal
- Telugu distinguishes single from geminate (doubled) consonants and the distinction changes word meaning: కల (kala — dream) vs. కళ్ళ (kalla — eyes). The difference is entirely in the duration of the consonant closure, which is internal and invisible on lips. On a phone call without hearing, all geminate pairs collapse into their single-consonant counterparts.
Four-series stop collapse
- Aspiration contrast is purely acoustic
- Telugu has aspirated, unaspirated, voiced, and voiced-aspirated stop series. The aspiration that distinguishes pairs is entirely in the burst of air — lips form the same closure for all four. On a phone call without hearing, these four series merge into one, collapsing a large portion of the consonant inventory.
Andhra vs. Telangana dialect gap
- Coastal Andhra and Hyderabad Telugu sound different
- Coastal Andhra Telugu (Vijayawada, Vizag) and Telangana Telugu (Hyderabad) differ significantly in vowel quality, verb endings, and prosodic rhythm. A deaf caller familiar with Vizag Telugu may not recognize fast Hyderabadi Telugu on a call — and vice versa. Regional calls carry the heaviest accent variation.
Retroflex series
- Retroflex consonants produce no visible lip change
- Telugu has a full retroflex consonant series (ట, ఠ, డ, ఢ, ణ, ళ) distinguished from dentals (త, థ, ద, ధ, న, ల). The retroflex sounds require the tongue curled back against the palate — no lip movement difference. These phonemically important contrasts are completely invisible and available only in the acoustic signal.
Vowel length compression
- Fast speech merges short and long vowel pairs
- Telugu short and long vowel pairs (a/ā, i/ī, u/ū, e/ē, o/ō) change word meaning but are compressed and merged in fast casual phone speech, especially in the Telangana variety spoken in Hyderabad. A deaf caller without acoustic access loses the duration signal that separates these pairs.

India is home to approximately 63 million deaf and hard of hearing people, with hearing disability the second most common disability in the country. NFHS-5 (2019–21) data shows that southern states including Telangana record higher disability rates than the national average. Of hearing-disabled Indians of working age, 73.9% are classified as marginal workers, meaning telephone-based systems — banking, government benefits, medical callbacks — are a primary exclusion frontier for Telugu-speaking deaf people.
State cochlear implant programs have been established in Andhra Pradesh for newly diagnosed children, but the large adult population with hearing loss navigates daily telephone communication without formal support. There is no mobile relay telephone service available through Jio, Airtel, or BSNL for deaf callers in Andhra Pradesh or Telangana. Indian Sign Language (ISL) interpreters remain scarce outside Hyderabad.
Captio AI means a deaf Telugu speaker in Warangal can follow a hospital callback in Telangana Telugu, navigate a bank IVR menu, or join a Google Meet with a team in Hyderabad — reading real-time captions on any phone, without relay infrastructure.

People love Captio AI
"My team speaks Telangana Telugu and I'm from Vizag — the accent difference was already hard, then add a phone call and I was completely lost. With Captio AI I follow every Google Meet in Hyderabadi Telugu. First time I've felt part of the meeting."
"Andhra Bank's phone banking IVR runs in Telugu and I couldn't navigate it independently. Captio AI shows the menu options in text as they're spoken. I handle my own banking calls now."
"The retroflex consonants in Telugu — like ట, ణ — look the same as their dental counterparts on lips. Captio AI gets them right in text. Hospital callbacks from AIIMS Mangalagiri are readable for the first time."
"WhatsApp calls with my son's family in the Gulf — they switch between Telugu and English constantly. Captio AI follows the code-switching accurately. I understand the full call instead of just the Telugu parts."
