Designed for the real moments that matter — not just quiet controlled environments.
From a far seat in a keynote hall in Delhi or Mumbai, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Hindi keynote from any seat.
At an academic conference — a research congress at an IIT or a scientific meeting in Pune — presenters speak fast and mix in dense terminology. Captio AI captions in real time and transcribes for later review.
Industry events and startup summits in Bengaluru or Hyderabad carry content that affects your work directly. Captio AI captions every speaker and panellist so you follow the whole session.
In a workshop or breakout, several voices contribute in a Hindi–English mix from around the table. Place Captio AI on the table and follow every contribution, including from the back.
The most useful conversations often happen over chai breaks and at the conference dinner. Captio AI works in these noisy, informal settings the same way it does in the main hall.
At an international conference in India, sessions switch between Hindi, English, and other languages. Live Translator captions foreign-language talks in real time so you follow the full programme.

Live captions from any seat
Point the phone toward the nearest PA output or speaker. Captio AI captions whoever is presenting in real time — from the front row or the back of a large conference hall.
Works without venue infrastructure
No hearing loop, no captioning service, no advance booking required. Captio AI works independently via microphone — whether or not the venue has provided any accessibility infrastructure.
Covers what official captioning does not
Official captioning, where it exists, typically covers the main stage only. Q&A sessions, workshops, breakouts, and networking are usually left uncaptioned. Captio AI covers all of it.
Record and review after
Record any session and upload it to Audio Transcription for a full written record. Use AI Summary to extract key takeaways — useful for dense technical content you want to process at your own pace.
60+ languages
For international conferences, foreign-language keynotes, or multilingual panels. Live Translator captions and translates in real time across 60+ languages with no manual switching between speakers.
Works for networking too
The conversations in hallways and at lunch matter as much as the sessions. Captio AI works in any setting — informal, noisy, unstructured — the same way it works in the main hall.
Why Hindi is hard to understand
Aspirated pairs
- Twelve stops that look like six on the lips
- Hindi distinguishes unaspirated and aspirated stops across six positions — p/ph, b/bh, t/th, d/dh, k/kh, g/gh. The aspiration is a puff of air with no lip cue, so all twelve sounds look like six. In a technical keynote, the breath that separates two terms is invisible from the audience.
Retroflex consonants
- Tongue-curl sounds with no visible signal
- Hindi's retroflex consonants — ʈ, ɖ, ɳ — are made with the tongue curled back toward the palate and give no signal at the lips. A deaf attendee watching a presenter's mouth sees the same shape for a dental and a retroflex sound, two different consonants that change the word.
Hindi–English code-switching
- Technical English inside Hindi sentences
- Indian conference speech mixes Hindi and English constantly — 'iska deployment', 'yeh framework', 'the results dikhate hain'. A deaf attendee must lip-read across two phonological systems that switch mid-sentence, often on exactly the technical terms that matter most in the talk.
Register gap
- Formal Sanskritised Hindi on the podium
- Podium Hindi reaches for a formal, Sanskritised register that differs from the everyday Hindi a deaf attendee lip-reads best — longer compounds, unfamiliar vocabulary, a more careful but denser delivery. The prepared keynote and the hallway chat are almost two different varieties.
Regional accents
- Speakers bring their state to the stage
- An all-India conference draws presenters whose Hindi carries Bihari, Bengali, Marathi, or South Indian colouring. A deaf attendee calibrated to Delhi Hindi meets shifting vowels and rhythms from one speaker to the next across a single session.

India carries one of the world's largest hearing loss burdens: the World Health Organization estimates 63 million people in India have significant auditory loss — around 6.3% of the population. The country's diagnostic and rehabilitation infrastructure is severely stretched, with an audiologist-to-population ratio of roughly one per 500,000. Millions of Indian professionals live and work with hearing loss that is under-diagnosed and under-supported.
India's conference and summit culture has grown fast — academic congresses at the IITs, the startup and technology summits of Bengaluru and Hyderabad, industry events in Mumbai and Delhi. These events run on spoken Hindi and English delivered over PA systems, and they are where research is shared, deals are made, and careers advance. Real-time captioning of keynotes, panels, and the crucial Q&A is almost never part of the programme, so a deaf professional pays the same registration fee for a fraction of the access.
Captio AI closes that gap. Point the phone toward the PA and read every Hindi keynote and Q&A answer from any seat, record a dense technical session for the full transcript, and follow the conversations over the chai break — so a deaf professional at an Indian conference gets the same value from the same event as everyone else in the hall.

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.

People love Captio AI
"Startup summit talks are pure Hindi–English mix, and from the back of the hall I caught almost nothing. Captio AI captioned both languages together from my seat. I read the whole pitch session and understood exactly which companies to follow up with."
"The keynote was in formal, Sanskritised Hindi with long compounds — a register I struggle to lip-read even up close. Captio AI captioned it accurately and I recorded the session for the transcript. I finally followed a full academic talk in real time."
"Panel Q&As move fast and the mic gets passed around a huge room. Captio AI captioned every answer as it was given. I stopped relying on a colleague to summarise the panel for me afterward — I had it all on my screen."
"Presenters at an all-India event bring their state's accent to the stage. Captio AI handled the Bihari and Marathi-tinged Hindi without me adjusting. As a speaker I could read the audience questions and answer what was actually asked."
