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.

Belarusian

Why Belarusian is hard to understand

Highest genetic deafness rate

  • Belarus has the world's highest carrier frequency of the 35delG GJB2 deafness mutation
  • A PMC genetic study found that the carrier frequency of the 35delG GJB2 mutation — the most common genetic cause of congenital sensorineural hearing loss — is higher in the Belarusian population than in any other country studied. This means that hereditary deafness rates in Belarus are structurally elevated compared to all European peers, creating a larger deaf and hard of hearing community per capita than the country's health infrastructure is designed to serve.

Trasianka code-mixing

  • Everyday Belarusian conversation mixes Belarusian and Russian in an unpredictable blend called trasianka
  • Trasianka is the common mixed speech of everyday Belarusian life — a blend of Belarusian and Russian grammar and vocabulary that most Belarusians use in informal settings. It does not follow fixed rules: different speakers produce different blends at different speeds. For a deaf lip-reader, this means tracking two languages' phoneme systems simultaneously in a pattern that varies from speaker to speaker and sentence to sentence.

Political suppression of disability

  • Under the Lukashenko government, disability advocacy and deaf infrastructure have been systematically limited
  • Belarus's political environment has restricted civil society organisations including disability advocacy groups. Belarusian Sign Language support organisations operate under severe constraints. The practical result is that official interpreter training, deaf community events, and everyday accessibility infrastructure have been suppressed in ways not seen in neighbouring European countries.

Fast urban Minsk speech

  • Minsk colloquial speech is rapid and blended, diverging from both formal Belarusian and standard Russian
  • Everyday spoken Belarusian in Minsk and major cities runs at high speed, mixes both language systems freely, and uses informal vocabulary that appears in neither formal Belarusian nor formal Russian dictionaries. A lip-reader who has learned formal Belarusian or formal Russian encounters a genuinely different phonological target in everyday street conversation.

Limited captioning technology

  • Belarusian speech recognition technology is among the least developed in Europe
  • Belarusian is one of the least resourced Slavic languages in terms of speech recognition, NLP tools, and captioning technology. The combination of limited tech support and limited political will means that a deaf Belarusian has almost no digital or institutional tools available for everyday communication accessibility.

The Challenge

Belarus has the world's highest genetic hearing loss mutation rate. Under political restrictions, deaf infrastructure has been systematically limited. No captions at the rynok, the marshrutka, or the family table.

Belarus faces a structurally elevated deaf and hard of hearing population due to an extraordinary genetic factor: a PMC study published in Frontiers in Genetics found that the 35delG GJB2 mutation — the most common genetic cause of congenital sensorineural hearing loss worldwide — has its highest carrier frequency in the Belarusian population compared to any other country. Hereditary deafness rates in Belarus are consequently among the highest per capita in Europe, creating a large deaf community that the country's health and disability infrastructure is not designed to serve. In daily life, deaf and hard of hearing Belarusians navigate the rynok, the marshrutka, the government office, and the family dacha gathering — all built entirely on oral exchange in trasianka, the mixed Belarusian-Russian speech of everyday life.

Belarusian Sign Language and disability advocacy organisations operate under severe political constraints in the current Lukashenko-governed state. Civil society organisations, including those supporting deaf Belarusians, have been systematically restricted. The practical result is that interpreter training, deaf community events, and everyday accessibility infrastructure have been suppressed in ways not seen in neighbouring EU member states. A deaf Belarusian at a government counter has no formal right to interpretation that is practically enforceable. At the market, the marshrutka, and the neighbourhood conversation, no provision exists at all.

Trasianka — the common everyday mixed speech of Belarus — creates a specific challenge for deaf people and for speech recognition technology: it does not follow fixed rules, varies from speaker to speaker, and blends Belarusian and Russian phonemes in patterns that differ by region, age, and context. Belarusian is also among the least-resourced languages in European speech recognition technology. Captio AI captions Belarusian speech in real time — including trasianka and Belarusian-Russian code-mixing — so the market, the government counter, and the family gathering are no longer settings you have to navigate alone.
