Why Captio AI

Built for conversations that don't wait

Captions as they speak, not after

Captio AI shows each word as it is spoken. You read what the person is saying while they are still saying it — not after they have finished and moved on.

No lip reading needed

You do not need to face the speaker or position yourself to see their mouth. Captio AI picks up speech from any direction — across a counter, at a table, in a busy street.

Works through background noise

Restaurants, pharmacies, busy streets, crowded waiting rooms. Captio AI separates speech from background noise so captions stay accurate where everyday conversations actually happen.

Follows any conversation

One person or six. Captio AI captions whoever is speaking at any moment — so you follow the thread at a dinner table or keep up with a counter exchange without losing track.

Any accent, any pace

People do not slow down or enunciate for you. Captio AI handles fast talkers, regional accents, and casual speech — the way people actually talk in real life.

Any language, no setup

When someone speaks a language you do not know, switch to Live Translator. They speak their language — you read in yours. No configuration needed. Works in 60+ languages.

Turkish

Why Turkish is hard to understand

Agglutination

  • Turkish words grow into long chains of suffixes that blur on the lips
  • Turkish is highly agglutinative: suffixes for tense, subject, object, location, and negation attach to the same root, creating words that can express in one token what English says in a full clause. At conversational speed, these extended words are delivered with minimal pause. For a lip reader, Turkish words produce long visual streams with few useful anchor points.

Vowel harmony

  • Vowel harmony reduces phonetic variety, making more words look the same on the lips
  • Turkish vowel harmony means that suffix vowels must match the quality of the root vowel. This creates phonetic regularity that reduces the range of visible lip shapes in connected speech. More words end up looking similar on the lips, making visual disambiguation harder.

Invisible hearing loss

  • Hearing loss in Turkey is invisible — people hide it rather than ask for accommodation
  • Research on Turkish deaf experience consistently shows that the biggest problem for people with hearing loss is worrying about not being understood. Unlike other visible disabilities, hearing loss is invisible — people with partial hearing loss routinely hide it rather than ask for help, leading to compounding social isolation.

Formal vs casual gap

  • Formal Turkish and street Turkish are genuinely different registers
  • Formal Turkish — used in media, government, and education — is deliberate and structured. Street Turkish, especially in Istanbul's working-class neighbourhoods and Anatolia, is faster, uses different vocabulary, and includes regional features. A deaf person learning standard Turkish will encounter significant comprehension gaps in informal daily settings.

Interpreter shortage

  • TİD certification is recent and interpreter numbers are insufficient
  • Turkish Sign Language (Türk İşaret Dili, TİD) has around 200,000 users but interpreter training has been inconsistent, with serious quality issues documented in the certification programme until 2020 reforms. For everyday informal settings — the tea house, the bazaar, the family table — there are no interpreters and no accessibility provision.

The Challenge

429,000 deaf people. 200,000 TİD users. Not enough interpreters for daily Turkish life.

Turkey has approximately 429,000 deaf people and around 200,000 users of Turkish Sign Language (TİD), according to population estimates from the Joshua Project and Turkish disability registries. For deaf people navigating Turkish daily life, exclusion begins in the most ordinary settings: the tea house where the conversation runs for hours, the bazaar where vendors speak fast colloquial Turkish, the family gathering where multiple generations talk at once. These are not formal or institutional settings. They are the daily texture of Turkish social life, and they have no interpreter and no accessibility provision.

TİD was legally recognised under Turkey's disability rights framework, but interpreter provision remains inadequate. The certification programme for TİD interpreters had documented quality issues until reforms in 2020. For everyday informal settings — the corner shop, the dolmuş, the çay evi — there are no interpreters and no legal obligation to provide one. Research on the Turkish deaf experience consistently shows that the biggest daily barrier is the fear of not being understood, leading to social withdrawal rather than engagement.

Turkey's 2020 Year of Accessibility brought new rules for public buildings, but informal daily-life settings remain largely unaffected. Hearing loss prevalence in Turkey is consistent with global trends, and an ageing population means the number of people navigating Turkish daily life with some degree of hearing loss is growing. Captio AI captions Turkish speech in real time — including fast agglutinated casual speech and regional varieties — so the çay evi, the bazaar, and the family table are no longer settings you have to navigate alone.

What you hear stays with you.

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.
