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.
Why Thai is hard to understand
Five-tone system
- Thai words differ only by tone — distinctions entirely invisible on the lips
- Thai distinguishes five phonemic tones: mid, low, falling, high, and rising. In a meeting, the same syllable 'mai' means 'no', 'new', 'silk', 'burn', or 'not' depending purely on tone. These distinctions are entirely acoustic — zero visible signal at the lips. A deaf participant reading Thai lip shapes sees the same mouth pattern for five different words.
Central vs Northern vs Southern tone patterns
- Bangkok and Chiang Mai Thai use different tone systems for the same words
- Standard Bangkok (Central) Thai and Kham Muang (Northern Thai) diverge in tone patterns, vowel quality, and vocabulary. Southern Thai has additional tonal distinctions. In a national company meeting, a Bangkok speaker and a Chiang Mai colleague produce different tonal signals for the same words — a deaf participant calibrated to one regional pattern misreads the other.
Isan Lao-influenced Thai
- Isan speakers — roughly a third of Thailand's population — use a Lao-based tonal system
- Isan Thai, spoken by an estimated 20 million people in northeastern Thailand, is closely related to Lao and has distinct phonological patterns from Central Thai. In Bangkok meetings with Isan-origin colleagues, a deaf participant calibrated to standard Central Thai encounters a systematically different tonal and phonological system.
Final consonant neutralization
- Thai final consonants that carry lexical meaning neutralize in fast meeting speech
- Thai restricts final consonant positions strictly. In fast meeting speech, word-final positions that carry lexical meaning reduce or neutralize — the acoustic cues that distinguish words at their end disappear. A deaf participant with any residual hearing loses these final-position signals at exactly the speed of a real working meeting.
Thai–English code-switching in Bangkok business
- Bangkok corporate meetings mix Thai and English throughout every session
- Bangkok's corporate, finance, and tech sectors run meetings where Thai and English alternate continuously — English KPIs, job titles, product names, and technical terms appear in Thai sentence structure. For a deaf participant, tracking which language is currently active and applying the right phonological expectations doubles the cognitive processing load throughout the meeting.

Over 2 million Thais hold disability cards; 18% of these are hearing impaired — approximately 360,000 registered deaf and hard of hearing Thais. The real number with significant hearing difficulty is estimated higher. Despite the 2007 Persons with Disabilities Empowerment Act, which mandated support services and accessibility provisions, the Thai government has historically not recognised equal employment rights for deaf people. Only 24% of disabled Thais over 15 years old are employed — one of the lowest rates in Southeast Asia. The meeting room is precisely where this gap is felt most acutely: formal employment in Thailand's financial, tech, and manufacturing sectors depends on verbal communication in meetings throughout the working day.
Thai Sign Language (TSL) is recognised but professional interpreter provision for corporate meetings in Bangkok is essentially unavailable. There are far fewer trained TSL interpreters than the demand from the working-age deaf population requires. Employers in Thailand's formal sector — banks, manufacturers, tech companies, government agencies — have no legal obligation to provide meeting captions or interpreters for deaf employees, and almost none do so voluntarily.
Thailand's economy is shifting toward knowledge work, with Bangkok's finance, logistics, and tech sectors growing rapidly. This creates an environment where verbal meetings are more central to professional advancement than ever. A PMC epidemiological study of 87,134 Thai adults found hearing impairment is associated with a range of health and economic outcomes — including reduced working capacity. Captio AI captions Thai in real time — handling all five tones, the Isan-accented voices of a third of Thailand's population, and the Thai-English code-switching of a Bangkok corporate standup — so every meeting is accessible.

People love Captio AI
"Bangkok tech standups mix Thai and English every sentence. The five tones in Thai are impossible to track visually. Captio AI handles both the tones and the code-switching accurately. I follow every product decision now."
"Financial meetings use formal Thai with heavy English vocabulary. Captio AI follows the formal register and the English sections accurately. The weekly team meeting is fully accessible for the first time in my career."
"Northern Thai has different tones from Bangkok standard and most tools just collapse the distinction. Captio AI handles the Kham Muang variety accurately. The production briefing and the all-hands meeting are both accessible now."
"Isan Thai in a regional meeting sounds very different from Bangkok Thai. Captio AI handles the Isan variety accurately. I can follow the full team meeting and the post-meeting discussion without asking colleagues to fill me in."
