Designed for the real moments that matter — not just quiet controlled environments.
From a far seat in a keynote hall at the SECC in Ho Chi Minh City or a venue in Hanoi, the speaker is distant and the hall is loud. Point Captio AI toward the nearest PA speaker and read every word of the Vietnamese keynote from any seat.
At an academic conference — a research congress at a Hanoi university or a scientific meeting in Ho Chi Minh City — presenters speak fast and mix in terminology. Captio AI captions in real time and transcribes for later review.
Industry events, startup summits, and product launches in Ho Chi Minh City or Da Nang carry content that affects your work. Captio AI captions every speaker so you follow the panel.
In a workshop or breakout, several voices contribute in a Vietnamese–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 cà phê 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 Vietnam, sessions switch between Vietnamese and English. 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 Vietnamese is hard to understand
Six tones
- Meaning carried by pitch, not by the mouth
- Northern Vietnamese has six tones, and the same syllable in different tones is a different word. Tone lives entirely in pitch, with no lip cue, so a deaf attendee watching a distant keynote speaker sees the mouth but gets none of the tonal information that fixes the meaning of a technical term.
Monosyllabic density
- Every syllable is a word, so every miss counts
- Vietnamese is largely monosyllabic — each syllable is a meaningful unit — and final consonants are unreleased and easy to miss. There is little redundancy to fall back on, so a deaf attendee who misses one syllable of a compound loses a whole piece of the meaning with no way to reconstruct it.
North–South divide
- Hanoi and Ho Chi Minh City sound different
- Southern Vietnamese merges tones that Northern keeps separate and reduces several consonants and vowels, so the same word looks and sounds different across the two regions. A conference with Hanoi and Ho Chi Minh City speakers presents a deaf attendee with two systems to track.
Unreleased final consonants
- Word endings with almost no visible movement
- Vietnamese final stops — p, t, k — are unreleased, formed without the closing burst that would give a lip-reader a cue. These finals distinguish words, so from a distant stage a deaf attendee cannot see the endings that separate one term from another.
Vietnamese–English code-switching
- Technical English inside Vietnamese sentences
- Vietnamese academic and startup talks drop English terms into Vietnamese sentences constantly. A deaf attendee lip-reading Vietnamese meets English phonology on the key vocabulary, then returns to Vietnamese, with no visual signal of the switch — often on the words that carry the talk.

Vietnam records around 1.3 million people with significant hearing impairment, with broader estimates reaching 2.5 million, and roughly 1,200 to 1,400 children are born with severe congenital hearing loss each year. National prevalence data is limited by the absence of a full registry, but screening studies find hearing loss in 4% or more of preschool children — much of it detected late for lack of newborn screening. A substantial professional population reaches working life with hearing loss that was identified and supported unevenly.
Vietnam's conference and events sector has grown rapidly alongside its economy — the academic congresses of Hanoi, the technology and startup summits of Ho Chi Minh City, the industry events at venues like the SECC. These run on spoken Vietnamese delivered over PA systems, with English woven into technical sessions. Real-time Vietnamese captioning of keynotes, panels, and Q&A is essentially never provided, and where any accessibility exists it does not reach the breakouts and networking where professional value is built.
Captio AI closes that gap. Point the phone toward the PA and read every Vietnamese keynote and Q&A answer from any seat, record a dense session for the full transcript, and follow the conversations over a cà phê break — so a deaf professional in Hanoi or Ho Chi Minh City 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
"Startup talks here are Vietnamese and English mixed, and the tones give me nothing on the lips. From the back of the hall I caught almost nothing. Captio AI captioned both from my seat. I read the whole pitch session and knew which teams to approach."
"The keynote was fast Northern Vietnamese, six tones, unreleased final consonants I cannot see. Captio AI captioned it accurately and I recorded the session for the transcript. I followed a full congress talk for the first time."
"The panel mixed Hanoi and Ho Chi Minh City speakers, and the two regions sound different to me. Captio AI captioned both and the audience questions from the floor. As a panellist I answered what was actually asked."
"Networking over cà phê is where the deals start, and it used to be the part I gave up on. Captio AI captioned the informal conversations at the reception so I could take part. That is where I found my co-founder."
