Designed for the real moments that matter — not just quiet controlled environments.
A Persian family dinner where multiple relatives talk across the table at once — toasts, stories, and arguments all happening in the same breath.
A Nowruz celebration or engagement party where the room is loud, the music is on, and close friends greet each other across the gathering.
A catch-up with old friends from Iran over tea and dates, with rapid back-and-forth conversation switching between topics and sometimes languages.
A local Iranian community meeting — a cultural association event or diaspora gathering where announcements are made and everyone responds at once.
Three generations around a sofreh — grandparents speaking formal Farsi, parents in Tehrani colloquial, children mixing in English — all at the same meal.
A casual evening at a Persian café, a teahouse gathering, or a house party where small clusters of people talk over background music.

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 Persian is hard to understand
Syllable elision
- Tehrani colloquial drops syllables mid-sentence
- Standard Farsi and colloquial Tehrani differ sharply: unstressed syllables are swallowed, words run together, and the clean phonology of formal speech disappears at a family dinner table. What sounds like one word may be three compressed together.
Uvular consonants
- Deep throat sounds leave the lips still
- Persian uvular /q/ and /gh/ are produced far back in the throat, producing virtually no visible lip movement. In a noisy gathering these sounds merge visually with plain /k/ and /g/, collapsing distinctions that carry real meaning.
Dialect gap
- Isfahani, Shirazi, and Tehrani sound different
- Persian dialects vary significantly in vowel quality and intonation. A deaf person who has learned to lip-read Tehrani Farsi finds Isfahani or Shirazi speakers at the same gathering using noticeably different mouth shapes for the same words.
Register collapse
- Colloquial Farsi darkens vowels unpredictably
- Formal Persian and colloquial speech differ in vowel quality: /a/ becomes /u/ (khaneh → khuneh), final vowels drop, and verb contractions stack. Casual family conversation runs entirely in the colloquial register, diverging from what a deaf person may have learned in literacy contexts.
Code-switching
- Diaspora gatherings shift between Persian and French or English
- Iranian diaspora social events in Europe, North America, and beyond freely mix Persian with French or English mid-sentence. The phonological system in any given phrase is unpredictable, and a deaf person cannot apply a single lip-reading strategy consistently.

A population-based study in Tehran found that 14.27% of adults have some degree of hearing impairment — including 4.04% with moderate loss, 0.67% with severe loss, and 0.48% who are profoundly deaf. Disabling hearing impairment affects an estimated 2.6 per 1,000 live births nationally, with rates varying from 0.9 to 5.8 per 1,000 across provinces. Iran has one of the highest rates of consanguineous marriage in the region, and studies show that 65% of parents of deaf children in Iran are consanguineous — nearly double the national average of 38% — making genetic hearing loss a particularly significant driver of deafness in the country.
Despite a national ear health programme under the Ministry of Health and Medical Education, Iran's Situation Analysis of Ear and Hearing Care identified systemic shortfalls: insufficient sign language training in schools, inadequate classroom infrastructure for deaf students, and a lack of culturally relevant instructional materials. Research with deaf and hard-of-hearing university students found that Persian as a spoken majority language presents significant barriers — speech therapy access is uneven, sign language interpreting is scarce in community settings, and deaf adults report feeling excluded from family social events where rapid, overlapping Farsi conversation dominates.
Captio AI captions Persian conversation in real time directly on a phone screen — so a deaf family member at a Nowruz dinner or a multigenerational sofreh can follow every toast and story as it is spoken, without waiting for someone to notice they have been left out.

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.
