Use Cases

Every situation covered

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

👨‍👩‍👧Family conversations

Ukrainian family meals — in Kyiv, Lviv, Odesa, or a family home abroad — are warm and conversation-dense, with hearing family members speaking at full pace in regional Ukrainian. Captio AI captions what they say in real time so a deaf or hard of hearing family member follows without asking anyone to repeat.

💼As a hearing colleague

Ukrainian workplaces run in Ukrainian for most exchanges, sometimes with Russian or English mixed in. A hearing colleague speaks naturally in whichever language fits the moment. Captio AI captions everything so a deaf or hard of hearing colleague follows desk conversations, quick questions, and team discussions without missing a word.

❤️Partners and relationships

When your partner is deaf or hard of hearing and Ukrainian is the language you speak at home. You talk naturally — the casual Ukrainian of daily life. Captio AI puts every word on their screen as you say it so nothing is lost between you.

🏠Living together

Daily home life in a Ukrainian household — calling from another room, talking over the evening news, quick exchanges before heading out. Captio AI covers the continuous thread of home conversation that a deaf or hard of hearing family member might otherwise have to guess at.

🤝Introducing someone new

When a deaf or hard of hearing person meets a new hearing Ukrainian speaker — at a family gathering, a community event, or through a mutual friend. Set up Captio AI and the conversation begins naturally, without anyone needing to adjust how they speak.

👥Mixed group settings

Group settings — a family gathering, a community celebration, or a mixed social event — where some people are deaf or hard of hearing and some are not. Captio AI captions whoever is speaking so every person in the group is fully part of the conversation.

You speak naturally

No slowing down, no special phrasing, no training required. Captio AI handles everything — you just talk the way you always do.

They read as you speak

Your words appear on their screen word by word while you are still talking. Not a summary after — the full sentence, in real time.

Works wherever you both are

Living rooms, offices, restaurants, social gatherings. No venue setup, no special conditions. Captio AI works anywhere you have a conversation.

No sign language from either side

You do not need to learn anything new. Neither do they. Captio AI bridges the gap without requiring any change to how either of you communicates.

Works with how you actually speak

Fast, accented, casual. Captio AI handles real speech — not just slow, clear dictation. You do not need to perform clarity for it to work.

Private by default

Your conversations are never recorded, stored, or shared. Audio is processed in real time and discarded immediately — nothing is kept.

Ukrainian

Why Ukrainian is hard to understand

Palatalisation contrast

  • Soft and hard Ukrainian consonants look the same at the lips
  • Ukrainian has a phonemic distinction between palatalised (soft) and non-palatalised (hard) consonants throughout its vocabulary — /t/ vs. /tʲ/, /n/ vs. /nʲ/, /l/ vs. /lʲ/. Palatalisation is produced with the tongue body raised toward the palate — invisible behind the teeth. A deaf lip-reader sees the same lip shape for both the hard and soft version of each consonant, yet these pairs distinguish different words in everyday Ukrainian speech.

Ukrainian central vowel /ɪ/

  • Ukrainian и is a unique vowel with no visible difference from similar sounds
  • Ukrainian has a central vowel /ɪ/ (и) distinct from both /i/ (і) and the Russian /ɨ/. This vowel distinction is auditory and visually extremely subtle — native speakers of Ukrainian and Russian disagree on exactly how it is positioned. A deaf lip-reader following a hearing family member has almost no visual basis for identifying this uniquely Ukrainian vowel against similar sounds.

Western vs. Eastern dialect

  • Lviv and Kharkiv Ukrainian follow different phonological patterns
  • Western Ukrainian (Galician, Lviv) preserves older features and was influenced by Polish, producing different phonological patterns from Eastern Ukrainian (Kharkiv, Dnipro), which carries heavier Russian influence. A deaf person who lip-reads one dialect region finds that a hearing family member from the other region uses different mouth shapes for some phonemes.

Surzhyk code-switching

  • Surzhyk — the Ukrainian-Russian mixed variety — blends two phonological systems unpredictably
  • The mixed variety known as Surzhyk blends Ukrainian and Russian grammatical and phonological features in ways that are fluid and unpredictable. In many Ukrainian families, especially in Eastern Ukraine, hearing family members naturally use Surzhyk. A deaf lip-reader cannot determine which phonological system is active without an auditory cue to signal the switch.

Consonant cluster density

  • Ukrainian everyday words are dense with consonant clusters
  • Ukrainian has dense consonant clusters in common vocabulary: 'взаємодія' (interaction), 'зустріч' (meeting), 'власний' (own), 'вступ' (introduction). In fast speech, these clusters compress into rapid articulatory sequences with very little mouth opening. The visual signal per phoneme is brief and overlapping — a deaf lip-reader sees a blur before the vowel opens.

The Challenge

Hearing loss in Ukraine: an old challenge compounded by a new crisis

In the European Region as a whole, approximately 190 million people have some hearing loss or deafness — 20% of the region's population (WHO Europe). Ukraine's disability situation analysis (2025, Global Disability Fund) identifies hearing-impaired people among the groups most marginalised in Ukrainian society, facing compounded barriers in employment, education, and social participation. Ukraine's EU integration process — which requires enforcement of legislation protecting the rights of persons with disabilities — has created a legal mandate for improvement, but the gap between formal rights and daily reality remains wide.

Since February 2022, Ukraine has faced an additional layer of hearing damage that is unprecedented in modern European history: noise-induced hearing loss from sustained military conflict. Blast exposure, artillery noise, and industrial damage to civilian infrastructure have affected both combatants and civilians across many regions of Ukraine. Audiologists and public health researchers have begun documenting what will be a long-term increase in hearing impairment among the Ukrainian population — adding to the pre-existing burden of age-related and congenital hearing loss.

Ukrainian Sign Language (USL) has a user community in Ukraine, and advocacy organisations — including the Ukrainian Society of the Deaf (UTOG) — have worked for decades to secure recognition and interpreter provision. But interpreter access in daily life — at family tables, in workplaces, in ordinary conversations between hearing and deaf family members — remains structurally absent. Captio AI captions natural Ukrainian speech in real time, in whatever dialect or mixed variety the hearing family member actually speaks, so a deaf family member reads what their hearing relatives are saying.
