Designed for the real moments that matter — not just quiet controlled environments.
From a far seat in a keynote hall in Dhaka or Kolkata, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Bengali keynote from any seat.
At an academic conference — a research congress at Dhaka University or a scientific meeting in Kolkata — presenters speak fast and mix in dense terminology. Captio AI captions in real time and transcribes for later review.
Industry events and professional seminars in Dhaka or Kolkata carry content that affects your work. Captio AI captions every speaker and panellist so you follow the whole session.
In a workshop or breakout, several voices contribute in a Bengali–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 cha 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, sessions switch between Bengali, 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 Bengali is hard to understand
Aspirated pairs
- Twelve stops that look like six
- Bengali distinguishes aspirated and unaspirated 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 look like six on the mouth. In a technical keynote, the breath that separates two terms is invisible from the audience.
Nasalized vowels
- Nasal contrasts made at the soft palate
- Bengali, especially the eastern variety spoken in Bangladesh, makes heavy use of nasalized vowels. Nasalization happens at the soft palate with almost no visible difference at the lips, so a deaf attendee watching a presenter sees no signal for a contrast that changes the word.
East–West divide
- Dhaka Bengali and Kolkata Bengali on one stage
- A Bengali conference may draw speakers from both Bangladesh and West Bengal, whose Bengali differs in vowel quality, intonation, and several phonemes. A deaf attendee calibrated to one variety finds the same words look different when a speaker from the other side of the border takes the podium.
Bengali–English code-switching
- Technical English inside Bengali sentences
- Urban Bengali academic and professional speech mixes in English terms constantly — 'er analysis', 'ei model ta'. A deaf attendee lip-reading Bengali must switch to English phonology on exactly the technical vocabulary that carries the point, then back again, with no visual warning.
Register gap
- Literary Sadhu-influenced podium Bengali
- Prepared Bengali talks reach for a more literary, formal register than the everyday Cholito Bengali a deaf attendee lip-reads best — different vocabulary and a more careful but denser delivery. The keynote and the corridor conversation can feel like two varieties of the language.

Bangladesh carries one of South Asia's heaviest hearing loss burdens: research in the Journal of Laryngology and Otology estimates that around 9.6% of the population — some 13.7 million people from the 2011 census — are deaf or hard of hearing with a loss of 40 dB or more, and a further third have some degree of hearing loss. Diagnosis and hearing-aid access are limited, especially outside the major cities, so a large professional population lives and works with under-supported hearing loss.
Academic and professional conference culture in Dhaka and across West Bengal runs on spoken Bengali and English delivered over PA systems. There is no national framework for real-time visual captioning at these events, and where any accessibility is offered it rarely extends past the main stage. The Q&A, the breakout sessions, and the networking — the parts of a conference where careers and collaborations are built — leave a deaf professional to piece together what they can from a distance.
Captio AI closes that gap. Point the phone toward the PA and read every Bengali keynote and Q&A answer from any seat, record a dense session for the full transcript, and follow the conversations over the cha break — so a deaf professional in Dhaka or Kolkata gets the same value from the same conference as everyone 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
"The congress keynote was formal, literary Bengali delivered fast from a far stage. I caught fragments. Captio AI captioned it from my seat and I recorded the session for the transcript. I followed the full talk for the first time at an academic event."
"Speakers mix Bengali and English on every technical point. Captio AI captioned both together without me doing anything. I read the whole seminar and understood exactly what the new framework meant for my team."
"The panel had Dhaka and Kolkata speakers, and the two varieties look different on the lips. Captio AI handled both. As a panellist I could read the audience questions and answer what was actually asked instead of guessing."
"Networking over cha is where the real conversations happen, and it used to be the part I skipped. Captio AI captioned the informal chats at the reception so I could take part. That is where I found my first two collaborators."
