Designed for the real moments that matter — not just quiet controlled environments.
GP visits at a government hospital (โรงพยาบาล) or private clinic, where appointments move quickly and the doctor explains symptoms, diagnosis, and prescription in rapid Central Thai.
Specialist consultations at a hospital outpatient department, where clinical English terms are mixed with Thai explanations and appointments are brief.
Pharmacy consultations at a ร้านขายยา (raan khaai yaa), where the pharmacist explains dosage and interaction warnings verbally — quickly, without written backup.
Dental appointments where the dentist explains the procedure and gives aftercare instructions between treatments.
Mental health consultations at a psychiatrist or counsellor's office, where every precise exchange carries clinical weight.
Emergency room visits at a government hospital A&E, where staff speak fast in Thai and English, masks are standard, and the clinical information is critical.

Built for the conversations where every word matters
Captions as the doctor speaks
Words appear on screen while the doctor is still talking. You read the diagnosis, drug name, or follow-up instruction at the same moment it is said — not after they have moved on.
Medical terminology handled accurately
Drug names, procedure names, clinical terms. Captio AI handles the vocabulary of a real consultation — not just everyday speech.
Review the appointment after
Record the consultation and upload it to Audio Transcription. Get a full written record of everything said — instructions, dosages, referrals — to review at home and share with a carer if needed.
Works in any clinical setting
Consultation rooms, hospital wards, A&E, dental chairs, pharmacy counters. Place the phone near the speaker and Captio AI captions whoever is talking.
Any language
For foreign-language doctors, specialists abroad, or appointments through an interpreter. Live Translator captions and translates in real time so you follow your diagnosis in the language you understand best.
100% private
Medical conversations are among the most sensitive there are. Captio AI processes audio in real time and discards it immediately. Nothing is recorded, stored, or shared.
Why Thai is hard to understand
Five-tone invisibility
- Thai's five tones change every word and are completely invisible on lips
- Thai is a 5-tone language — mid, low, falling, high, and rising. The same syllable with a different tone means a completely different word. In a clinical consultation, a doctor distinguishing a diagnosis, a drug name, or a dosage instruction by tone alone produces output a deaf or hard of hearing patient lip-reading receives none of. Every Thai word carries a tonal marker that is invisible on the lips — and every lip-reading error in Thai has a one-in-five chance of producing the wrong word entirely.
Unreleased final stops
- Thai final consonants are silent on the lips
- Thai syllables frequently end in unreleased stop consonants (-k, -p, -t) that carry no visible lip movement — they simply stop the airflow with no explosive release. In words for body parts, drug instructions, and medical procedures, these final stops disappear completely from the visual channel, leaving the lip-reader with less than half the phonological information they need.
Polite register shift
- Clinical Thai uses a polite formal register with different vocabulary
- Thai has clearly marked polite and formal registers — clinical settings use honorific vocabulary and politeness particles (ครับ/ค่ะ) that shift the phonological shape of key words. A deaf patient calibrated to casual Thai may not recognise the same concepts in the formal register a doctor uses. Doctors addressing elderly patients often mix Central Thai with local vocabulary, adding another layer of register shift.
English medical terminology
- Thai doctors routinely switch to English for diagnoses and drug names
- Clinical vocabulary in Thailand is largely derived from English and Latin, with Thai doctors switching to English terms for diagnoses, drug names, and procedures mid-sentence. A deaf patient expecting Thai encounters an English word at the critical clinical moment — and then returns to Thai for the surrounding explanation.
Regional tonal systems
- Northern, Northeastern, and Southern Thai each have different tonal systems
- Central Thai (Bangkok) is the clinical standard, but Kham Mueang (Northern Thai), Isan (Northeastern Thai), and Southern Thai have different tonal systems and extensive vocabulary differences. A deaf patient from Chiang Mai or Khon Kaen in a Bangkok hospital, or vice versa, encounters a tonal and lexical profile substantially different from what they lip-read at home.

Thailand's Department of Empowerment of Persons with Disabilities records 392,359 to 398,659 registered individuals with hearing or communicating disabilities — approximately 18.7% of all registered persons with disabilities in the country. A hearing health survey of Bangkok residents published in 2024 found overall hearing loss prevalence of 53.02% among study participants, with a moderate-or-greater degree of impairment affecting 2.8% — with those aged 65 and over being more than 8.5 times as likely to have hearing loss. As Thailand's population ages, this figure will grow substantially.
Thailand's Persons with Disabilities Empowerment Act 2007 grants deaf individuals the legal right to sign language interpreters and medical services. However, the gap between legal right and practical availability has been long documented. As recently as 2025, the Ministry of Social Development and Human Security launched a programme to address this gap — creating 77 sign language interpreter positions, one per province, to serve more than 432,495 hearing-impaired individuals nationally. One interpreter per province serves thousands of deaf people. It is an acknowledgement of how far Thailand still has to go, not a solution.
In rural provinces, where the majority of Thailand's deaf population lives, a government hospital appointment means navigating fast-spoken Thai, English-derived drug names, and a regional dialect — with no interpreter, no written summary, and no way to ask the question twice. Captio AI captions Thai speech in real time — at the government hospital, the ร้านขายยา, and the clinic — without requiring a pre-booked interpreter.

People love Captio AI
"My doctor at Siriraj switches between Thai and English for every drug name. The tones in the Thai parts are impossible to lip-read. Captio AI captions both languages in real time. I read the diagnosis as the doctor says it."
"Doctors here speak Northern Thai mixed with Central Thai. I was lost before the first sentence finished. Captio AI captions everything and I follow my own clinical consultation for the first time."
"The pharmacist at the ร้านขายยา gives dosage instructions verbally and assumes I will remember. With Captio AI I read every instruction as she speaks and screenshot the screen before I leave. No more guessing at doses."
"Emergency room visits were terrifying — fast Thai, masks, staff moving around me. Captio AI gives me real-time captions even in a busy A&E. I can follow what the nurse is saying without needing someone to interpret."
