Why Captio AI

Built for the speed of a real meeting

Captions while they are still speaking

Words appear on screen as each person talks — not after they finish. You read what someone is saying at the same moment everyone else hears it.

Works in any meeting format

Conference rooms, open-plan offices, video calls, all-hands. Place the phone on the table or hold it — Captio AI handles the rest.

Handles fast speech and crosstalk

Captio AI is designed for real meetings, not controlled dictation. It follows whoever is speaking loudest at any moment, keeping up with the natural pace of discussion.

No setup, no explaining

Open the app and place the phone. No pairing, no telling colleagues what you are doing, no requesting anything from the meeting organiser.

Review everything after

Record the meeting and upload it to Audio Transcription for a full written record. Use AI Summary to extract decisions and action items so nothing from the meeting gets lost.

60+ languages

For international teams, multilingual meetings, or colleagues who switch between languages mid-discussion. No setup required — Captio AI detects and captions in real time.

Turkish

Why Turkish is hard to understand

Suffix-final meaning

  • Turkish grammatical meaning arrives at the end of long suffix chains — easy to miss
  • Turkish is agglutinative — grammatical meaning arrives at the end of long suffix chains. In a fast meeting, 'gidiyormusunuz' (are you going?) is a single spoken word where the meaningful content arrives last. A deaf participant who misses the suffix sequence misses the grammatical point of the sentence.

Vowel harmony chains

  • Turkish vowel harmony chains collapse at the visual level in fast meeting speech
  • Turkish vowel harmony means suffixes shift to match root vowel quality through long predictable chains. In fast meeting speech, these chains merge into reduced vowel clusters where front/back and round/unround distinctions collapse acoustically — and the visual signal at the lips is even less informative than the acoustic signal.

Istanbul vs Anatolian accents

  • Istanbul and Anatolian Turkish present different phonological patterns on the same call
  • Standard Istanbul Turkish differs from Anatolian regional accents — Ankara, Izmir, Trabzon, Gaziantep — in vowel quality and syllable rhythm. A meeting with colleagues from multiple cities presents several phonological patterns simultaneously, and a deaf participant calibrated to Istanbul pronunciation misreads Anatolian speech.

Turkish–English code-switching in corporate settings

  • Istanbul corporate meetings demand two active phonological systems simultaneously
  • Istanbul's tech, finance, and media sectors run meetings that freely mix Turkish and English technical vocabulary mid-sentence. For a deaf participant, tracking which language is active at any point doubles the cognitive processing demand of following the meeting.

Arabic and Persian loanwords in formal register

  • Formal Turkish business speech introduces unexpected consonant patterns from Arabic and Persian
  • Formal Turkish business speech draws on Arabic and Persian loanwords with consonants — uvulars, pharyngeals — not present in native Turkish phonology. In a board meeting or legal presentation, these loanwords create unexpected consonant patterns that a deaf person familiar with everyday Turkish does not anticipate.

The Challenge

Over a million Turks with hearing loss — and most corporate meetings remain inaccessible.

Official Turkish census data counts approximately 89,000 people with hearing impairment and 55,000 with speaking disability. Broader prevalence estimates, accounting for mild and moderate hearing loss that does not meet official disability certification thresholds, suggest 1–2 million Turkish people experience significant hearing difficulty in daily life. Turkey's disability employment law requires companies with 50 or more employees to maintain a 3% disabled workforce in the private sector and 4% in the public sector — but the law applies to all disability categories combined, and enforcement and workplace accommodation provision remain inconsistent.

Türk İşaret Dili (TİD — Turkish Sign Language) was banned from education in the late 1800s under Ottoman language policy and the prohibition continued through the 1950s during the era of emphasis on oralism. Legal recognition came only in 2005 through the Law on Disabled Individuals. Decades of educational suppression mean that TİD interpreter training infrastructure is still developing, and professional corporate interpreter provision for Turkish business meetings is severely limited. Many deaf Turkish professionals in Istanbul's corporate sector navigate meetings without any accommodation.

Turkey's economy is diversifying rapidly, with Istanbul's tech, finance, and media sectors expanding and hybrid work normalising. This makes meetings more frequent and more central to professional advancement than in earlier generations of Turkish employment. For deaf and hard of hearing Turkish professionals, this shift intensifies rather than reduces the communication gap. Captio AI captions Turkish meeting speech in real time — including the formal suffix-heavy language of board presentations, the fast code-switching of an Istanbul startup standup, and the Anatolian-accented voices of regional colleagues on a national call — so no meeting is inaccessible.

"Istanbul tech meetings switch between Turkish and English constantly. Captio AI follows both languages and the transitions between them accurately. I stopped falling behind in sprint planning the moment I started using it."

"Turkish board meetings use formal loanword vocabulary that sounds nothing like everyday Turkish. Captio AI handles the formal register accurately. I can follow the full meeting without a TİD interpreter who may not know the financial terminology."

"Izmir-accented Turkish in team meetings was difficult to follow even with residual hearing. Captio AI captions the regional variety accurately. I no longer need a colleague to summarise what was said after every meeting."
