Use Cases

Works in every situation

Designed for the real moments that matter — not just quiet controlled environments.

💬Everyday Conversations

Most Persian conversations happen fast, at normal pace, without warning. Captio AI captions every word as it's spoken, so you can follow without asking anyone to repeat themselves.

🤟Communicating with Deaf & HoH

Hearing people often don't know how to adapt when talking with deaf or hard of hearing Persian speakers. Captio AI turns their speech into real-time captions, so the conversation can happen naturally on both sides.

💼Meetings

In Persian meetings, decisions happen fast and people talk over each other. Captio AI captions every speaker as they talk, so you never miss a decision or a question directed at you.

🎓Lectures

Persian lecturers speak quickly, cover complex material, and rarely repeat themselves. Captio AI gives you a live transcript of everything said, so you can follow the content instead of straining to hear it.

🏥Doctor Appointments

Doctors speak quickly in Persian and use clinical language that's easy to mishear. Captio AI shows you everything they say in real time, so you can follow your diagnosis and ask the right questions.

🤝Job Interviews

Missing a question in a Persian interview means answering wrong or asking for a repeat. Captio AI shows you every word the interviewer says, so you can focus entirely on your answer.

📱Phone & Video Calls

Persian phone and video calls are harder to follow than in-person conversations. No lip reading, often poor audio quality. Captio AI captions whoever is speaking in real time, so you do not need to ask for repeats.

👥Group Settings

In Persian group conversations, multiple people talk at once and the thread moves fast. Captio AI keeps up with whoever is speaking, so you can follow without losing where the conversation is going.

🍽️Restaurants & Cafes

Background noise in Persian-speaking restaurants and cafes makes speech hard to follow. Captio AI focuses on whoever is speaking to you, so you can have a real conversation through the noise.

✈️Traveling

In Persian-speaking cities, airports, and hotels there is no margin for mishearing. Captio AI captions speech in real time, so you can navigate confidently wherever you go.

🎤Conferences & Events

At Persian conferences, speakers are far away, acoustics are unpredictable, and you cannot ask for a repeat. Captio AI gives you a live transcript of every speaker, so you can follow the full event from any seat.

📺TV & Media

Built-in subtitles on Persian TV, films, and videos are often wrong, delayed, or missing. Captio AI captions whatever is playing in real time, so you are not dependent on what the content provides.

Dialect & Accent Support

Persian dialect & accent support

Supports Farsi (Iranian Persian), Afghan Dari, and Tajik Persian.

Tehrani dialect

Standard Iranian Persian (Farsi) — based on the Tehran variety and used in national broadcasting, education, and official communication across Iran. The prestige form and most widely understood Persian variety. Captio AI handles Tehrani Farsi with full accuracy.

Mashhadi dialect

Eastern Iranian Persian — spoken in Mashhad, Khorasan, and northeastern Iran. Has a distinct accent with some vowel differences from Tehran Persian, and proximity to Central Asian Persian varieties. Captio AI handles Mashhadi dialect accurately.

Dari dialect

Afghan Persian — spoken across Afghanistan as one of its two official languages. More conservative than Iranian Farsi, preserving vowel distinctions that have been lost in Tehran Persian. Has distinct vocabulary and intonation. Captio AI handles Dari accurately.

Hazaragi dialect

Spoken by the Hazara people of central Afghanistan — a distinct variety of Dari with Mongolian and Turkic vocabulary influence. Captio AI handles Hazaragi in its standard conversational form, with accuracy highest for speech closer to Standard Dari.

Tajiki dialect

Persian spoken in Tajikistan — written in Cyrillic script since the Soviet era. Closer to Dari than Iranian Farsi in phonology, with significant Russian and Uzbek loanwords. Captio AI handles Tajiki speech accurately, displaying captions in Cyrillic script.

Privacy

What you hear stays with you.

Gone the moment it ends

Captio AI processes your Persian 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 Persian doctor's appointment or job interview never ends up in a training dataset. Not ours. Not anyone else's.

Iranian Sign Language (زبان اشاره ایران)

Iran's deaf community uses Iranian Sign Language. Despite years of advocacy and international pressure, Iranian Sign Language had not been officially recognized by law as of 2024, though government statements indicated recognition was pending. An estimated 1.5 to 3 million people in Iran have hearing disabilities, though only around 200,000 are officially registered.

Human Rights Watch documented cases in 2018 of deaf and hard of hearing people being denied healthcare outright. The government funds cochlear implant surgeries but has not provided sufficient sign language interpreters for hospitals, courts, or other critical settings. Around 2,000 deaf people gathered in Tehran in 2018 to call for an end to systematic discrimination against their community.

For hard of hearing Persian speakers in Iran, the absence of interpreter access in healthcare is one of the most significant daily barriers. Medical consultations in Tehran's hospitals move fast and use formal Farsi vocabulary. Captio AI provides a way to follow spoken Persian in real time in these situations.
