Use Cases

Every situation covered

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

👔In-person interviews

In a Sofia, Plovdiv, or Varna office — an interviewer speaking Bulgarian at corporate pace. Captio AI captions every question in real time so you read the full sentence before responding.

💻Video interviews

Video interviews on Teams or Zoom — standard for remote rounds at Bulgarian companies and international employers. Put the call on speaker and follow every question in real time.

📞Phone screens and initial calls

The initial HR screening call in Bulgarian — fast, formal, with reduced unstressed vowels. Captio AI captions in real time so compressed audio does not become the barrier.

👥Panel interviews

Panel interviews at Bulgarian companies, public institutions, or multinational tech employers. Captio AI follows each panelist in real time even as they shift between Bulgarian and English.

🌍International and foreign-language interviews

For roles at IT and outsourcing firms where the interview shifts between Bulgarian and English. Live Translator handles both in the same session without manual switching.

🎯Assessment centres

Structured competency assessments and group exercises — common at major Bulgarian banks and tech employers. Captio AI covers all facilitator speech and candidate interaction.

Why Captio AI

Built for the room where a missed word has real consequences

Read the full question before you answer

Every word appears on screen as the interviewer speaks. You read the question completely before responding — nothing guessed, nothing reconstructed.

Works in person and on any call format

In-person interviews, video calls, phone screens. Place the phone on the table or point it toward the audio — Captio AI handles every format.

Discreet by design

The app runs quietly on your phone. Place it on the table or hold it naturally. No explanation needed, no drawing attention to the accommodation.

No asking for repeats

Asking an interviewer to repeat a question signals uncertainty. Captio AI means you never need to — you read it in real time and answer with confidence.

Any language

For international roles, multilingual panels, or interviews conducted in a second language. Live Translator captions and translates in real time so language is never the barrier.

Private by default

Interview conversations are sensitive. Captio AI processes audio in real time and discards it immediately — nothing is stored, nothing is shared.

Bulgarian

Why Bulgarian is hard to understand

Vowel reduction

  • Unstressed Bulgarian vowels reduce to schwa in fast interview speech
  • Like Russian, Bulgarian reduces unstressed vowels in natural speech: unstressed /a/ becomes /ɐ/ or /ə/, unstressed /o/ reduces. Research on Bulgarian vowel reduction confirms that speakers often resist reduction in formal contexts — but in a fast Sofia corporate interview at professional pace, unstressed syllables do compress, leaving lip-readers with minimal visual movement between stressed syllables.

Consonant clusters

  • Bulgarian permits initial and medial consonant clusters in formal vocabulary
  • Bulgarian allows initial consonant clusters (pl-, sv-, sp-, str-) and complex medial clusters in formal vocabulary. In fast interview speech, these clusters produce dense consonant sequences that must be visually tracked without inter-consonant pauses, making word boundary identification difficult.

Bulgarian-English switching in IT sector

  • Sofia's tech and outsourcing sector mixes Bulgarian and English mid-sentence
  • Bulgaria has a rapidly growing IT and business process outsourcing sector in Sofia, and corporate tech interviews mix Bulgarian and English extensively. An interviewer may begin a question in Bulgarian and use English technical terms mid-sentence, or vice versa. A deaf candidate tracking Bulgarian is suddenly watching English without warning.

Eastern-Western dialect variation

  • Standard Bulgarian (Balkan dialect base) differs from Western varieties
  • Standard Bulgarian is based on the Central Balkan dialects of eastern Bulgaria, covering northern and central Bulgaria. Western Bulgarian dialects — including those around Sofia — have some phonological differences from the eastern base. An interviewer from Plovdiv may produce slightly different vowel qualities from one from Sofia.

Formal corporate register

  • Bulgarian corporate interviews use formal vocabulary with Slavonic and international roots
  • Bulgarian formal corporate interview register uses literary vocabulary including Slavonic-origin terms and international loanwords (мениджмънт, компетентност, мотивация) less common in everyday colloquial Bulgarian. A deaf candidate whose visual vocabulary comes from informal speech may encounter formal terms with unfamiliar lip patterns.

The Challenge

6,500 members of Bulgaria's deaf community — and an employment market that has not kept pace with legal commitments

The Union of the Deaf in Bulgaria counts over 6,500 members and supports 13 commercial companies focused on self-employment initiatives for deaf Bulgarians — an indicator of how structurally excluded deaf people have been from mainstream employment. Bulgaria has ratified the UN Convention on the Rights of Persons with Disabilities and has disability employment legislation providing for quotas and reasonable accommodation. The EU Disability Forum has found that across Europe, the majority of persons with disabilities remain locked out of quality employment — Bulgaria is no exception, with disability employment rates below EU averages.

Bulgaria's economy has undergone significant transformation since EU accession, with a growing IT and outsourcing sector, a manufacturing base, and traditional sectors including agriculture and tourism. The interview formats at major Sofia employers — banks, tech companies, state enterprises, and multinationals — are structured verbal processes without standard captioning. EU social protection documentation for Bulgaria notes reliance on disability benefits rather than employment as a persistent pattern, suggesting barriers to employment entry that the interview stage reflects.

Bulgarian's linguistic structure creates a specific phonological challenge. Vowel reduction in unstressed syllables, similar to Russian, leaves large portions of words visually compressed. Formal corporate vocabulary differs from everyday speech. And Sofia's tech sector creates code-switching interviews requiring simultaneous tracking of Bulgarian and English. Captio AI requires no employer arrangement: open the app at the start of the събеседване, place the phone on the desk, and every Bulgarian sentence — unstressed vowels resolved from audio — is available in real time.
