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.

Indonesian

Why Indonesian is hard to understand

Regional language reality

  • Daily conversation happens in Javanese, Sundanese, Balinese — not Bahasa Indonesia
  • Bahasa Indonesia is the formal national language, but across Java, Bali, Sumatra, and Sulawesi, daily household and neighbourhood conversations happen primarily in local languages: Javanese, Sundanese, Balinese, Batak, and hundreds of others. For a deaf person, following everyday Indonesian life means following whichever regional language the speaker grew up with — not the standard Bahasa they may have learned.

Constant code-switching

  • Indonesian conversations shift between Bahasa, local languages, and English without pattern
  • In Jakarta, Surabaya, and Bali, a single café conversation can shift between formal Bahasa Indonesia, Javanese, and English within minutes. The switching happens without any signal and follows no predictable pattern. Following the meaning requires all three simultaneously.

Gaul (street slang)

  • Everyday informal Bahasa Indonesia is a completely different language from formal Indonesian
  • Indonesian gaul (street slang) shortens, reverses, and reinvents words. Formal 'tidak' becomes 'nggak' or 'gak'. 'Bagaimana' becomes 'gimana'. The vocabulary and structure of informal everyday Indonesian bears little resemblance to what is taught in school or broadcast on television.

Loud everyday settings

  • Warung stalls, pasar markets, and mosques are the social infrastructure of Indonesian life
  • Indonesian daily life centres on warung stalls, pasar markets, mosques, and angkot (shared minibuses) — all acoustically demanding and all built entirely on spoken communication. These are where Indonesian daily social life happens, and they have no visual accessibility provision.

Particle reduction

  • Indonesian grammar relies on particles and prefixes that disappear in fast speech
  • Indonesian marks questions with 'kah' and 'apakah', shows direction with 'ke' and 'dari', and uses verbal prefixes (me-, ber-, di-) that change meaning entirely. In fast casual Indonesian — at the warung stall, on the angkot, at a family gathering — these markers are reduced, dropped, or swallowed. Without them, sentences that look identical in lip shape carry opposite meanings.

The Challenge

18.5 million people. Navigating 270 million people speaking hundreds of languages.

Indonesia has 18.5 million people with hearing loss — one of the highest burdens globally — spread across a country of 270 million people, 17,000 islands, and hundreds of local languages. In a 2015 national survey, Indonesia's Central Statistics Agency found that almost 9 million Indonesians over the age of 10 had difficulty hearing. For deaf and hard of hearing people navigating Indonesian daily life, the challenge is not one language but the patchwork of Javanese, Sundanese, Balinese, Batak, and other local languages that form the texture of daily existence in each region — alongside a formal national language that is rarely what people actually speak at home.

Around 74% of deaf Indonesians are unemployed, according to research on the Indonesian deaf community. Government facilities, hospitals, and religious institutions have very few sign language interpreters. Indonesian Sign Language (BISINDO) exists but is not universally understood even within the deaf community, where multiple regional sign languages are still in use. For everyday settings — the warung, the pasar, the mosque, the angkot — there is no interpreter, no captioning standard, and no accessibility infrastructure. There are also 79 schools for the deaf in a country with over 2 million deaf students, meaning most have no educational access at all.

Hearing loss prevalence in Indonesia is growing, driven by high rates of chronic suppurative otitis media (particularly in rural areas), noise exposure, and limited preventative healthcare access across the archipelago. The 4.2% hearing loss prevalence figure from the WHO regional study understates the full challenge. The gap between the scale of the deaf and hard of hearing population and the support available in daily Indonesian life is one of the widest in Southeast Asia. Captio AI captions Indonesian speech in real time — including colloquial gaul, regional Javanese-influenced speech, and the language mixing of urban Indonesian daily life — so the warung, the pasar, and the family gathering are no longer settings you have to navigate alone.
