Use Cases

Every situation covered

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

👨‍👩‍👧Calls with family and friends

A call home to family in Gwynedd, Ceredigion, or Cardiff — catching up in Welsh with relatives who speak their regional variety at natural speed.

💼Work calls and conference calls

A work call with Welsh-speaking colleagues in a Welsh-medium workplace — professional Welsh with sector vocabulary and the dialect of wherever the caller is based.

🏥Medical and healthcare calls

A callback from a meddygfa (GP surgery) in Bangor or a fferyllfa (pharmacy) in Swansea — healthcare calls in Welsh where every word about a result or prescription matters.

🏦Banks, utilities, and customer service

A call from a Welsh-language bank line, a utility company, or a local council service — automated Welsh or English menus followed by an agent at full speed.

🌍International calls

A call from Welsh-speaking family in Patagonia (Argentina), mixing Welsh with Spanish mid-conversation.

📹Video calls — FaceTime, WhatsApp, Zoom

A FaceTime or WhatsApp video call with Welsh family across Wales or the Welsh diaspora — the standard platform for staying connected in a geographically dispersed community.

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.

Welsh

Why Welsh is hard to understand

Lateral fricative ll

  • The Welsh 'll' is produced inside the mouth with no lip movement
  • Welsh 'll' is a voiceless lateral fricative — air flows around the sides of the tongue, deep inside the mouth. The lips barely change position. A lip-reader watching a Welsh speaker say 'llan', 'llaeth', or 'llyfr' sees almost no lip movement for a sound central to Welsh vocabulary.

Consonant mutations

  • Initial consonants change in context — invisibly and unpredictably
  • Welsh has an extensive system of initial consonant mutations: the first sound of a word changes depending on grammatical context — 'pen' (head) becomes 'ben', 'mhen', or 'phen' depending on what precedes it. A lip-reader expecting one consonant shape sees a completely different one, with no visual forewarning.

North-South dialect split

  • Northern and southern Welsh differ substantially in vowels and vocabulary
  • Northern Welsh (Gwynedd, Anglesey) and southern Welsh (Cardiff, Swansea, the Valleys) differ in vowel quality, vocabulary, and speech rate. The vowel 'u' is produced differently in north and south; many words used in the north are unrecognised in the south. A phone call from Caernarfon reads differently from one from Swansea.

Welsh-English code-switching

  • English appears mid-sentence without pause or signal
  • Almost all Welsh speakers are bilingual and code-switch between Welsh and English constantly mid-sentence. The switch carries no pause or visual marker, and since Welsh and English share some consonants, the transition is hard to detect visually. A lip-reader tracking Welsh consonant shapes is suddenly facing English phonology.

Vowel length

  • Long and short vowels change Welsh word meaning invisibly
  • Welsh distinguishes long and short vowels that carry different meanings. The lip position is the same for both; only the duration differs. On a phone call, this durational distinction is invisible to a lip-reader tracking Welsh speech.

The Challenge

Hearing loss in Wales: 610,000 people and a Welsh-language gap

Approximately 610,000 people in Wales are deaf or have hearing loss — part of the 12 million adults across the UK with hearing impairment. The Royal National Institute for Deaf People (RNID) projects that by 2035, 14.2 million UK adults will have hearing loss greater than 25 dB HL, reflecting demographic ageing. Hearing loss is the leading cause of years lived with disability for the over-60 population in the GBD 2019 study for the European region.

Wales presents a compound access barrier not present in other UK regions: Welsh-speaking deaf and hard of hearing people navigate a system where British Sign Language (BSL) is used by the UK deaf community, but Welsh-medium services and Welsh-language captioning are significantly less available than English equivalents. Welsh-medium healthcare, government, and public phone services are legally required under the Welsh Language Standards, but real-time captioning for Welsh-language calls is not routinely provided. For deaf and hard of hearing Welsh speakers, this means that using Welsh on the phone — with a GP, a council, or family — is more inaccessible than using English.

Captio AI captions every Welsh phone call in real time — from a northern Welsh-speaking family call from Gwynedd to a GP surgery callback in Cardiff Welsh — so deaf and hard of hearing Welsh speakers can follow every word independently.

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.
