Use Cases

Every situation covered

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

👨‍👩‍👧Calls with family and friends

A catch-up call with family in the Western Cape, Gauteng, or the Northern Cape — talking in Afrikaans about the week's news at the relaxed pace of a home phone call.

💼Work calls and conference calls

A work call with Afrikaans-speaking colleagues or clients in Cape Town or Pretoria — professional Afrikaans in a business or farming sector context.

🏥Medical and healthcare calls

A callback from a GP surgery, a hospital in Stellenbosch, or a pharmacist in Paarl — healthcare calls where understanding every word about medication or results matters.

🏦Banks, utilities, and customer service

A call from Capitec, a municipality, or an insurance company — fast-talking agents in Afrikaans following a script, often with hold music between stages.

🌍International calls

A call from an Afrikaans-speaking relative in the Netherlands, New Zealand, or the UK, mixing Afrikaans with English or Dutch mid-conversation.

📹Video calls — FaceTime, WhatsApp, Zoom

A WhatsApp video call with Afrikaans family in the Western Cape — the platform of choice for South African families staying in touch across provinces or continents.

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.

Afrikaans

Why Afrikaans is hard to understand

Guttural /χ/ and /ɣ/

  • The Afrikaans 'g' is produced entirely at the back of the throat
  • Afrikaans 'g' is a velar fricative produced at the back of the throat. Words like 'goed', 'groot', and 'gebruik' open with a sound that leaves no visible trace on the lips. A lip-reader sees what looks like a word starting with a vowel.

Schwa reduction

  • Unstressed vowels collapse in fast Cape Afrikaans
  • In casual Cape Afrikaans, unstressed vowels reduce to a near-silent schwa and function words become murmurs. A sentence that looks distinct on paper becomes a blur of content words on the lips, with grammatical connectors invisible.

Kaapse Afrikaans dialect

  • Cape Coloured Afrikaans has different vowel qualities and rhythm
  • Kaapse Afrikaans — spoken by Cape Coloured communities in the Western Cape — uses different vowel qualities, a faster contracted rhythm, and some Arabic and Malay-derived vocabulary. On a phone call between different dialect speakers, lip-reading cues shift unpredictably.

Afrikaans-English code-switching

  • English appears mid-sentence without pause or signal
  • South African speakers switch between Afrikaans and English seamlessly — a pattern so pervasive it is unremarkable. A lip-reader tracking Afrikaans word shapes is suddenly presented with English phonology, then back again, with no visual marker indicating the switch.

Stop devoicing

  • Voiced and voiceless stops share the same lip shape
  • Voiced stops in Afrikaans devoice readily in running speech, and aspirated vs unaspirated distinctions vary across dialects. The acoustic cue that separates /b/ from /p/ disappears — and the lip shapes are already identical.

The Challenge

Hearing loss in South Africa reaches every community

Approximately 12 million South Africans live with hearing loss, with prevalence varying sharply by region: 12.35% in Cape Town, 17.5% in Tshwane primary health care settings, and up to 19.88% in rural Limpopo communities. The WHO estimates around 124,000 South Africans experience total hearing loss. Hearing impairment is the third most commonly reported disability in South Africa — after visual impairment and physical disability — yet audiological services remain concentrated in urban centres, leaving rural and peri-urban communities with severely limited access.

South African Sign Language (SASL) became the country's 12th official language in December 2023, a landmark recognition — but interpreter services remain critically underfunded. For Afrikaans-speaking deaf and hard of hearing people specifically, services in SASL or English may not reach speakers in smaller Western Cape towns, and phone and video calls with family or service providers remain largely inaccessible without a hearing intermediary.

Captio AI captions every Afrikaans phone call in real time — from a family catch-up in the Western Cape to a bank callback from Pretoria — so deaf and hard of hearing South Africans can follow every word independently.

Privacy

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.

"The GP surgery calls in Afrikaans and I couldn't follow the nurse speaking quickly about my results. With Captio AI I read the words as she speaks and don't need to call back to ask what she said."
