Use Cases

Every situation covered

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

👨‍👩‍👧Calls with family and friends

A call from family in Almaty or Shymkent — parents who speak fast and mix Kazakh with Russian naturally. Captio AI captions each word as it arrives so you follow the whole conversation without asking them to slow down or switch languages.

💼Work calls and conference calls

A work call with colleagues in Nur-Sultan where Kazakh and Russian alternate mid-sentence across the same meeting. Put the call on speaker, point Captio AI toward the audio, and follow every agenda item in whichever language is being used.

🏥Medical and healthcare calls

A callback from a poliklinika (clinic) or the healthcare authority — formal Kazakh spoken quickly with medical vocabulary. Captio AI captions every instruction, dosage, and appointment detail so nothing high-stakes is missed.

🏦Banks, utilities, and customer service

A call from Kazkommertsbank, Halyk Bank, or a government office — automated systems in Kazakh, fast agents, and official terminology. Captio AI captions whatever comes through the speaker so you have the information in writing.

🌍International calls

A call from Kazakh diaspora family in Russia, Germany, or Mongolia, or from Kazakhs in neighbouring Kyrgyzstan or Uzbekistan. Live Translator handles the language and regional variation so distance is not an additional barrier.

📹Video calls — FaceTime, WhatsApp, Zoom

A WhatsApp or Telegram video call — the main channels for Kazakh families across the vast geography of Kazakhstan and Central Asia. Captio AI listens through the speaker and captions in real time alongside the video.

Why Captio AI

Built for the calls you have been avoiding

Captions as they speak

Words appear on screen word by word while the other person is still talking. You read what they say at the same pace everyone else hears it — no delay, no reconstruction.

Works on any call app

Captio AI does not need to integrate with any platform. Put the call on speaker, point the microphone toward the audio, and read the captions. It works the same way for any app on any device.

No more asking for repeats

Every word is on screen as it is said. If you missed something, glance at the caption rather than interrupting the call — the full sentence is there.

Handles call audio accurately

Compressed phone audio is less clean than in-person speech. Captio AI is built for real-world audio conditions, including the reduced quality of standard phone and VoIP calls.

Any language

For calls with family abroad, international colleagues, or foreign-language customer service. Live Translator captions and translates in real time with no manual setup.

Record and review after

Record any call and upload it to Audio Transcription. Get a full written record of everything said — useful for medical instructions, work decisions, and anything worth having in writing.

Kazakh

Why Kazakh is hard to understand

Back-throat consonants

  • Kazakh's uvular and velar sounds are invisible
  • Kazakh uses three back-of-mouth consonants that are entirely invisible during lip reading: /ɣ/ (voiced velar fricative, written ғ), /q/ (uvular stop, written қ), and /χ/ (voiceless velar fricative, written х). These are among the most common consonants in Kazakh words, yet they are produced far behind the lips and leave no visual trace. On a phone call, where lip reading is not available, their acoustic quality is also compressed.

Russian code-switching

  • Nur-Sultan and Almaty callers mix Kazakh and Russian mid-sentence
  • In Kazakhstan's major cities, Kazakh and Russian coexist in daily speech — and callers routinely switch between them within a single sentence. A phone call from a colleague in Almaty may begin in Kazakh, shift to Russian for a technical term, return to Kazakh for the closing. For a hard of hearing person, this doubling of phonological systems requires twice the cognitive load to parse.

Nine-vowel reduction

  • Vowel harmony collapses in fast speech
  • Kazakh has nine vowels in a front-back harmony system that governs suffix forms. In fast conversational speech — the register typical of phone calls — unstressed vowels reduce and the harmony distinctions that mark grammatical relationships become acoustically faint. A hard of hearing caller following vowel harmony as a parsing cue loses that scaffold in rapid speech.

Regional dialect contrast

  • Northern and Southern Kazakh sound different
  • Northern Kazakh — spoken in Nur-Sultan, Karaganda, and the Russian-influenced north — has significant Russian phonological influence and more loanwords than Southern Kazakh. Southern Kazakh, spoken around Shymkent and in regions bordering Uzbekistan, has Uzbek phonological influence and a more distinct Kazakh pronunciation. A call from the north versus the south presents a different phonological profile entirely.

Agglutinative compression

  • Long suffix chains blur together in fast speech
  • Kazakh is agglutinative — case, plurality, tense, and aspect are all expressed as suffix chains on a single word root. In fast phone conversation, these suffix chains compress into a blur that requires knowing the grammar deeply to segment. For a hard of hearing caller who has missed a phoneme in the root, the entire word becomes unrecoverable.

The Challenge

Kazakhstan's 150,000 registered deaf face 2.5 hours of interpreter access per month

Approximately 150,000 individuals are officially registered as having hearing impairments in Kazakhstan, though experts estimate the actual number may reach 250,000 — reflecting underdiagnosis and limited access to audiological services outside major cities. The highest prevalence of hearing loss is recorded among working-age adults aged 18 to 59, who account for 20 percent of all reported cases. For context, a 2026 cross-sectional analysis published in Frontiers in Public Health described significant gaps in hearing loss burden assessment infrastructure in Kazakhstan, with no nationally representative prevalence figure available from systematic screening.

The government provides deaf Kazakhstanis with 30 hours of sign language interpretation per year — roughly two and a half hours per month. This allocation must cover medical appointments, government interactions, employment, education, and any other formal communication need. Hearing-impaired people in Kazakhstan are officially assigned only the third disability group, the lowest classification, which excludes them from housing support and many other state privileges available to people with higher-group disabilities. Employment of deaf people remains a central challenge, with the gap between deaf and hearing applicants documented in advocacy reporting as a function of communication barriers rather than capability.

Captio AI captions every Kazakh phone call in real time — so whether it is a callback from a Nur-Sultan clinic, a family call from Almaty, or a work call in the language Kazakh-Russian mix that defines urban Kazakhstan, the words appear on screen as they are spoken.

People love Captio AI

"Work calls in Kazakhstan are half Kazakh, half Russian depending on who is speaking. I used to just agree to things I had not understood. Now Captio AI captions both languages as they switch — I follow what is actually being said."

"The poliklinika called about my test results in fast formal Kazakh. I understood almost nothing. Now I always run Captio AI when a medical number calls — I read the results and instructions clearly and do not have to call back to ask again."

"Southern Kazakh sounds different from what people speak in Almaty. My family calls from villages near Shymkent and the accent is strong. Captio AI handles the southern vowels and gets the words right — better than I expected."

"Bank calls in Kazakhstan are hard — automated systems in Kazakh, then the agent switches to Russian. Captio AI follows both languages through the same call. I did not have to ask anyone to help me deal with my own bank account."
