Use Cases

Every situation covered

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

🍽️Family dinners

An Azerbaijani family dinner — Novruz celebrations, a wedding feast, or a Sunday family meal — with multiple generations talking across the table in Azerbaijani and sometimes Russian.

🎉Social gatherings and parties

A toy or engagement celebration where the room fills with guests from different regions of Azerbaijan and the conversation is loud and overlapping.

Friend catch-ups

A catch-up with old friends over black tea and pastries, with rapid conversation shifting between personal news, shared memories, and family updates.

🌍Multilingual groups

A community gathering at a cultural centre, mosque, or neighbourhood association where announcements are made and everyone responds freely.

👥Community and club meetings

Three generations at a family table — grandparents in regional Azerbaijani, parents in standard Baku speech, grandchildren mixing in English or Russian.

🏠Shared living situations

A casual evening at a friend's home or a neighbourhood tea gathering where small groups form and conversations flow freely.

Why Captio AI

Built to keep you in the conversation, not just in the room

Captions whoever is speaking

Captio AI follows the dominant voice at any moment — whoever is loudest in the microphone's direction. In a group conversation, this tracks the active speaker naturally.

Works through background noise

Restaurants, living rooms, parties, outdoor gatherings. Moderate background noise does not prevent accurate captions — Captio AI is built for real environments, not quiet rooms.

Place it in the centre and forget it

Put the phone on the table or in the middle of the group, microphone facing the conversation. No positioning it after every speaker change, no adjusting between voices.

Less effort, less fatigue

The cognitive load of following a group conversation by lip-reading and reconstructing speech is exhausting. Captio AI handles the following so you can direct your energy toward actually being in the conversation.

60+ languages

For multilingual families, mixed-language social groups, or gatherings where people switch between languages mid-conversation. No setup required between language changes.

No setup between conversations

Open the app and place the phone. No configuration per setting, no briefing the group, nothing to manage between conversations. It works for any group, in any situation.

Azerbaijani

Why Azerbaijani is hard to understand

Vowel harmony

  • Eight vowels — front and back series look the same on lips
  • Azerbaijani has a vowel harmony system with eight vowels divided into front and back series. The distinction between harmonic pairs is primarily a matter of tongue position, not lip shape — at a family dinner table, front /y/ and back /u/, or front /ø/ and back /o/, produce nearly identical lip rounds. Fast colloquial speech compresses these vowel distinctions further.

Uvular consonants

  • Back-of-throat sounds leave the lips still
  • Azerbaijani has uvular and back-velar consonants — /q/, /x/, and /ɣ/ — produced far back in the throat with essentially no forward lip or jaw movement. These sounds appear frequently in native Azerbaijani vocabulary and are visually indistinguishable from the corresponding front-velar /k/ and /g/ at a social gathering.

North-South dialect split

  • Baku Azerbaijani and South Azerbaijani differ significantly
  • Standard Azerbaijani is based on the Baku urban dialect; South Azerbaijani spoken in Iranian Azerbaijan uses the Tabriz norm. The two varieties differ in phonology, loanword inventory, and prosody. Family gatherings that mix relatives from Baku and from Tabriz or Ardabil present a deaf person with two distinct phonological systems at the same table.

Azerbaijani-Russian switching

  • Russian enters mid-sentence in urban Azerbaijani gatherings
  • In Azerbaijan, Russian remains widely used in urban professional settings and among older generations. Social gatherings — particularly in Baku — routinely shift between Azerbaijani and Russian mid-sentence. A deaf person applying Azerbaijani lip-reading patterns is suddenly reading Russian phonology without warning.

Loanword clusters

  • Russian and Persian borrowings introduce unfamiliar consonant sequences
  • Azerbaijani has absorbed extensive Russian and Persian loanwords with consonant cluster patterns foreign to native Azerbaijani phonotactics. In educated social speech these cluster-heavy borrowings are common. A deaf person trained on native Azerbaijani vocabulary finds these sequences producing unfamiliar lip patterns.

The Challenge

Hearing loss in Azerbaijan: the scale of daily exclusion

Azerbaijan has an estimated 624,000 people living with some form of disability — approximately 6.4% of the national population. Sensory impairments, including hearing loss, represent a significant share of this figure. The Global Burden of Disease 2019 study found that hearing loss is the most common cause of years lived with disability across Eastern Europe and Central Asia, with age-standardised prevalence rising sharply over the past three decades. Azerbaijan ratified the UN Convention on the Rights of Persons with Disabilities in 2009, committing to accessible services and sign language recognition, but implementation of accessibility standards in social and community settings remains limited.

Deaf and hard-of-hearing people in Azerbaijan face significant access gaps in daily social life. Sign language interpretation services are concentrated in major cities, and the availability of real-time communication support at family gatherings, community events, and informal social settings is effectively nil. The country's transition through the post-Soviet period left many disability institutions under-resourced, and the gap between legal frameworks and lived access — particularly for rural and diaspora communities — remains wide. Azerbaijani diaspora communities in Russia, Germany, and Turkey face the additional challenge of navigating social events without any accessible infrastructure in their host country.

Captio AI captions Azerbaijani conversation in real time on a phone screen — so a deaf family member at a Novruz gathering or a multigenerational dinner in Baku, Ganja, or an Azerbaijani diaspora event in Istanbul or Berlin can follow every story and toast as it is spoken.
