Every situation covered
Designed for the real moments that matter — not just quiet controlled environments.
From a far seat in a keynote hall in Tehran, the speaker is distant and the Persian is formal and fast. Point Captio AI toward the nearest PA speaker and read every word of the keynote from any seat.
At an academic conference — a research congress at a Tehran university or a medical meeting in Mashhad — presenters speak fast and pack talks with terminology. Captio AI captions in real time and transcribes for later review.
Industry events, technology summits, and product briefings in Tehran carry content that affects your work. Captio AI captions every speaker so you follow the panel and miss nothing.
In a workshop or breakout, several voices contribute in Persian from around the table. Place Captio AI on the table and follow every contribution, including from the back of the room.
The most useful conversations often happen over tea 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 Persian 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 Persian is hard to understand
Back-of-throat consonants
- Sounds made deep in the throat, invisible on the lips
- Persian has several consonants produced far back in the mouth and throat — خ, غ, ق — with no visible lip movement. These appear in formal and technical vocabulary, so from a distant stage a deaf attendee sees nothing of the sounds that distinguish one keynote term from another.
Ezafe linking
- An unstressed vowel that ties phrases together
- Persian links nouns to their modifiers with the ezafe, a short unstressed -e that is often not written and easily missed. It carries essential grammatical structure but sits on weak, fleeting vowels, so a deaf attendee cannot see how the parts of a complex phrase connect on the lips.
Short-vowel omission
- The vowels that carry meaning are the ones that drop
- Persian short vowels are unstable, unwritten, and reduced in fast speech, while long vowels stay stable. In a rapid keynote the short vowels that separate two words weaken and disappear, leaving a deaf attendee with a consonant skeleton and no way to fill it in.
Tehrani versus Dari
- Iranian and Afghan Persian differ on the podium
- A Persian-language conference may bring Tehrani Iranian Persian and Afghan Dari speakers together. They differ in vowels and in whether certain back consonants merge, so a deaf attendee calibrated to Tehrani Persian meets different lip shapes from a Dari-speaking presenter.
Persian–English terms
- Technical English inside Persian sentences
- Iranian academic and industry talks drop English and international scientific terms into Persian sentences. A deaf attendee lip-reading Persian meets a foreign term with unfamiliar phonology on exactly the words that carry the talk, with no visual signal of the switch.

Hearing loss and professional access in Iran
Hearing loss is common in Iran and shaped by specific structural factors. A population study in Tehran found hearing impairment in around 14% of people, with roughly 5% having disabling hearing loss, and the country's high rate of consanguineous marriage means hereditary hearing loss is markedly elevated — consanguinity among the parents of deaf children runs at about 65%, nearly double the general rate. National reviews describe an ear-and-hearing-care system stretched to meet this burden.
Iran hosts a large programme of academic congresses, medical conferences, and technology events, concentrated in Tehran and other major cities. These run on spoken Persian delivered over PA systems, with English and international scientific terms woven into technical sessions. Real-time Persian 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 Persian keynote and panel answer from any seat, record a dense technical session for the full transcript, and follow the conversations over tea — so a deaf professional in Tehran gets the same value from the same conference as everyone in the hall.
