Why Captio AI

Built for the speed of a real meeting

Captions while they are still speaking

Words appear on screen as each person talks — not after they finish. You read what someone is saying at the same moment everyone else hears it.

Works in any meeting format

Conference rooms, open-plan offices, video calls, all-hands. Place the phone on the table or hold it — Captio AI handles the rest.

Handles fast speech and crosstalk

Captio AI is designed for real meetings, not controlled dictation. It follows whoever is speaking loudest at any moment, keeping up with the natural pace of discussion.

No setup, no explaining

Open the app and place the phone. No pairing, no telling colleagues what you are doing, no requesting anything from the meeting organiser.

Review everything after

Record the meeting and upload it to Audio Transcription for a full written record. Use AI Summary to extract decisions and action items so nothing from the meeting gets lost.

60+ languages

For international teams, multilingual meetings, or colleagues who switch between languages mid-discussion. No setup required — Captio AI detects and captions in real time.

Swahili

Why Swahili is hard to understand

Coastal dialect variation

  • Coastal and inland Swahili present different phonological systems in the same meeting
  • Kiamu and Kimvita coastal dialects differ markedly from the inland Nairobi standard. A colleague from Lamu sounds genuinely different from one trained in Nairobi. In a national company meeting, a deaf participant faces multiple phonological systems at once.

Swahili–English code-switching

  • East African meetings switch languages mid-sentence without any warning signal
  • East African professional meetings frequently switch mid-sentence between Swahili and English — sometimes mid-clause. For a deaf participant, tracking which language is active requires two separate lip-reading and context-processing systems simultaneously.

Noun class prefix reduction

  • Swahili noun class prefixes that carry grammar disappear in fast meeting speech
  • Swahili noun class prefixes (ki-, vi-, m-, wa-, u-) carry grammatical information. In fast meeting speech, these short prefixes reduce to near-inaudible consonant gestures — a deaf person using residual hearing loses the grammatical scaffold of the sentence.

Sheng overlay in urban meetings

  • Nairobi office speech layers Sheng slang over standard Swahili mid-meeting
  • In Nairobi office environments, urban Sheng slang infiltrates business conversation. Technical vocabulary can arrive in Sheng rather than standard Swahili, meaning the word a deaf participant expects in formal Swahili may appear in a completely different form.

Verb extension chains

  • Swahili verb extension suffix chains articulate as a single fast blur
  • Swahili builds complex meaning through verb extensions — causative, passive, reciprocal — appended as suffixes. In fast professional speech, multi-morpheme verb forms articulate as a single fast spoken unit with no visible boundary between the root and its extensions.

The Challenge

Millions of deaf East Africans navigate professional life with almost no workplace support.

Kenya's 2019 National Population Census counted 153,381 deaf people aged over five years, with 63% living in rural areas. Hearing impairment rates are rising: one in ten Kenyans is now estimated to have some form of hearing loss, compared to five to eight per hundred two decades ago, and projections suggest that by 2030 nearly 3.6 million Kenyans will have significant hearing loss. Tanzania faces a comparable burden. In a region where formal employment is already limited, deaf and hard of hearing East Africans face compounded barriers — and the professional meeting, now increasingly conducted via phone or laptop, is where those barriers are most acute.

Neither Kenya Sign Language (KSL) nor Tanzania Sign Language (TSL) has a professional interpreter provision standard for corporate or NGO settings. The two sign languages are significantly different, meaning that an interpreter trained for Kenyan deaf employees cannot directly serve Tanzanian colleagues. Deaf employees navigating the East African professional world encounter not just the absence of workplace communication support, but fragmented community resources that rarely align with formal employment needs.

The WHO African region carries some of the highest rates of unaddressed hearing loss globally, with the majority of people having no access to hearing rehabilitation, audiological services, or any form of hearing device. Sub-Saharan Africa's noise-induced hearing loss burden — particularly in industrial and construction workplaces — adds to the natural hearing loss population. The result is that a large and growing share of East Africa's workforce is navigating meeting-heavy professional environments without any communication access tool. Captio AI captions Swahili in real time — standard Nairobi Swahili, coastal varieties, and the Swahili-English code-switching of a Nairobi corporate office — so that the weekly team meeting is something a deaf employee can fully participate in.

People love Captio AI

"Our Nairobi team meetings switch between Swahili and English constantly and the urban Sheng slang creeps in during casual discussion. Captio AI follows all of it. I participate in the actual conversation now, not a summary of it afterwards."

"Tanzanian Swahili sounds different from the Nairobi standard and most tools collapse the distinction. Captio AI handles the Dar es Salaam variety accurately. Video calls with the Nairobi office are finally manageable."

"Mombasa coastal Swahili has its own cadence that was impossible to lip-read in client meetings. Captio AI handles the coastal dialect. I can follow the full client presentation and the Q&A that follows."

"Uganda meetings mix Swahili and English heavily. Captio AI handles the code-switching and the regional Swahili vocabulary accurately. The standup is no longer the part of my day that exhausts me most."
