Designed for the real moments that matter — not just quiet controlled environments.
A Diwali or Eid gathering where relatives from different states speak Awadhi, Bhojpuri, or Punjabi alongside Hindi. Captio AI captions each dialect so you follow every relative, not just the ones who speak standard Hindi.
A multigenerational Sunday lunch in Delhi or Lucknow where grandparents speak one variety and grandchildren another, with the TV contributing background noise. Captio AI follows whoever is speaking near your phone.
A wedding reception where conversation moves between family groups, languages, and accents — and where the expectation is that everyone participates. Captio AI keeps you in every exchange.
An evening with friends at a local dhaba or someone's home, where fast casual Hinglish makes lip-reading nearly impossible. Captio AI captions the full Hindi-English mix.
A neighbourhood mohalla meeting or residents' gathering where multiple contributors speak quickly in Hindi with no formal structure. Captio AI captions each speaker in real time.
A multigenerational family gathering where the conversation ranges from formal Hindi to regional dialect to English, and nobody thinks to make accommodations. Captio AI makes the accommodation invisible.

Built to keep you in the conversation, not just in the room
Captions whoever is speaking
Captio AI follows the dominant voice at any moment — whoever is loudest in the microphone's direction. In a group conversation, this tracks the active speaker naturally.
Works through background noise
Restaurants, living rooms, parties, outdoor gatherings. Moderate background noise does not prevent accurate captions — Captio AI is built for real environments, not quiet rooms.
Place it in the centre and forget it
Put the phone on the table or in the middle of the group, microphone facing the conversation. No positioning it after every speaker change, no adjusting between voices.
Less effort, less fatigue
The cognitive load of following a group conversation by lip-reading and reconstructing speech is exhausting. Captio AI handles the following so you can direct your energy toward actually being in the conversation.
60+ languages
For multilingual families, mixed-language social groups, or gatherings where people switch between languages mid-conversation. No setup required between language changes.
No setup between conversations
Open the app and place the phone. No configuration per setting, no briefing the group, nothing to manage between conversations. It works for any group, in any situation.
Why Hindi is hard to understand
48 dialect zones
- A single family gathering can span Awadhi, Bhojpuri, Braj, and Delhi Hindi
- Hindi has 48 major dialects with distinct vowel patterns, consonant distributions, and prosody. A family gathering in India can include grandparents speaking Awadhi (Lucknow region), relatives from Varanasi using Bhojpuri-inflected speech, and grandchildren speaking Delhi's Khari Boli variety. A deaf person calibrated to standard Hindi encounters multiple unfamiliar phonological systems at the same dinner table, with no signal when the variety shifts.
Aspirated consonant pairs
- Hindi's 16 stop consonants include auditory distinctions invisible on the lips
- Hindi has aspirated/unaspirated consonant pairs (p/ph, b/bh, t/th, d/dh, k/kh, g/gh and retroflex equivalents) that change word meaning throughout the lexicon. Aspiration is an auditory distinction — air released after the consonant — that is not visible in lip movement. In fast group conversation, aspiration reduces further, and minimal pairs that depend on this distinction become unresolvable from visual information alone.
Hinglish code-switching
- Urban and semi-urban gatherings move freely between Hindi and English
- At social gatherings across urban and semi-urban India, conversation switches between Hindi and English mid-sentence without announcement: 'Yaar, tu seriously ek baar try kar, it's like totally different.' The English segment carries specific content, and the phonological shift from Hindi to English is dramatic and unannounced. A deaf person following Hindi loses the thread the moment the switch happens, and vice versa.
Nasal vowel elision
- Hindi's nasalized vowels become invisible on the lips in fast group speech
- Hindi has nasalized vowel phonemes that carry grammatical and lexical distinctions. In fast casual speech, nasalization is inconsistently produced and may drop entirely. The distinction between a nasalized and oral vowel is in any case invisible on the lips — a deaf person cannot distinguish हाँ (yes, nasalized) from हा (informal affirmative, oral) from lip movement, or any other nasalized minimal pair.
Register gap
- The Hindi of family gatherings differs substantially from formal or media Hindi
- Hindi has a formal register using Sanskrit-derived vocabulary and a colloquial register using Perso-Arabic or regional alternatives. These differ substantially in vocabulary, rhythm, and pace. Family gatherings run entirely in colloquial register at full speed — and the colloquial register is not what most learning materials or formal speech production uses, creating a gap between what a deaf person has prepared to lip-read and what is actually spoken at the table.

India is home to an estimated 63 million people with hearing impairment — approximately 6.3% of the population — making it one of the largest deaf and hard of hearing communities in the world. A study published in the Annals of Otology, Rhinology & Laryngology found an overall prevalence of hearing loss of 25.1% in a Delhi survey population, with approximately 32% of those affected having profound loss. Despite these numbers, India has only around 250 trained or semi-trained sign language interpreters — a ratio that makes formal communication support structurally unavailable for almost everyone in this population.
The burden falls hardest in informal social life, where no formal accommodation is possible and no institutional support exists. A review of psychosocial challenges facing hearing-impaired Indians found that deaf people are consistently isolated from family and friends and face unsympathetic attitudes in social settings. The Indian family gathering — multigenerational, frequent, loud, and rich with dialectal diversity — is where a deaf family member is expected to participate fully, without any accommodation being made for them.
Captio AI captions real conversational Hindi in real time — across Delhi Khari Boli, Bhojpuri-inflected speech, Awadhi, and Hinglish code-switching — so the Diwali gathering, the family Sunday lunch, and the neighbourhood mohalla are conversations a deaf or hard of hearing person can follow without the sustained effort of lip-reading a room full of different dialect speakers.
