Designed for the real moments that matter — not just quiet controlled environments.
A call home to family in Sarajevo, Mostar, or Banja Luka — catching up in Bosnian at the pace of a family phone call.
A work call with Bosnian colleagues or contacts — professional Bosnian with the formal register and the regional accent of wherever the caller is based.
A callback from a dom zdravlja (health centre) in Sarajevo or a ljekarnica (pharmacy) — healthcare calls where missing medication details or a referral has real consequences.
A call from a Bosnian bank, utility company, or public service line — automated menus followed by an agent in standard Bosnian.
A call from Bosnian diaspora in Germany, Austria, or Sweden, mixing Bosnian with German or Swedish mid-conversation.
A WhatsApp or Viber video call with family or friends in Bosnia — the platform of choice for the large Bosnian diaspora staying connected with home.

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.
Why Bosnian is hard to understand
Ijekavian diphthongs
- The Ijekavian /ij/ reflex creates syllable runs invisible on the lips
- Bosnian uses the Ijekavian pronunciation of Old Slavic yat — 'mlijeko' (milk) where Ekavian Serbian has 'mleko'. The /ij/ diphthong creates an extra syllable that, in fast speech, contracts into a brief glide with minimal lip movement, making word parsing harder.
Soft vs hard palatal pairs
- ć/đ and č/dž share identical lip shapes
- Like Serbian and Croatian, Bosnian distinguishes soft palatals (ć, đ) from hard post-alveolars (č, dž) by tongue position alone. Both pairs produce the same lip shape. On a video call, the difference between 'kuća' and words with 'č' is invisible.
Ottoman loanword phonology
- Turkish and Arabic vocabulary introduces unfamiliar sound patterns
- Bosnian has a significant layer of Ottoman Turkish and Arabic loanwords — čaršija, džamija, mahala — used in everyday urban Sarajevo speech. The phonology of these words (uvular, pharyngeal, and affricate sounds) differs from native Slavic patterns, adding unpredictability.
Sarajevo-Herzegovinian split
- Urban and regional varieties read differently on the lips
- Urban Sarajevo Bosnian has its own pace and vocabulary distinct from the Herzegovinian dialect spoken in Mostar and the west. A phone call from Bihać reads differently from one from Sarajevo. A lip-reader calibrated to one regional variety is disadvantaged on calls from another.
Three-language context
- Bosnian, Croatian, and Serbian shift mid-call without signal
- Bosnia has three co-official languages (Bosnian, Croatian, Serbian) that are mutually intelligible but phonologically divergent in markers like Ijekavian vs Ekavian and soft vs hard affricates. Speakers may shift between them on a call without signaling the change, creating unexpected lip-shape variation.

Bosnia and Herzegovina has a population of approximately 3.5 million. Applying the Global Burden of Disease 2019 European prevalence rates gives an estimated 700,000 people with some degree of hearing loss. A study examining 40 years of data across centres for social care and employment offices in BiH identified 1,044 hard of hearing and deaf persons registered in the formal support system — a figure that represents a small fraction of the estimated total and reflects chronic underregistration in a country still rebuilding post-war administrative infrastructure.
Bosnia's disability policy is fragmented between the Federation of Bosnia and Herzegovina and Republika Srpska, with no unified national framework for deaf support. Sign language recognition, interpreter provision, and phone accessibility fall between administrative jurisdictions. The WHO Epidemiology of Deafness study situates the Western Balkans among the regions where post-conflict institutional gaps compound the access barriers already created by hearing loss — leaving deaf and hard of hearing Bosnians with fewer formal supports than neighbours in the EU.
Captio AI captions every Bosnian phone call in real time — from a family call from Sarajevo to a dom zdravlja callback in standard Bosnian — so deaf and hard of hearing users can follow conversations independently.

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.
