Designed for the real moments that matter — not just quiet controlled environments.
Most Thai conversations happen fast, at normal pace, without warning. Captio AI captions every word as it's spoken, so you can follow without asking anyone to repeat themselves.
🤟Communicating with Deaf & HoHHearing people often don't know how to adapt when talking with deaf or hard of hearing Thai speakers. Captio AI turns their speech into real-time captions, so the conversation can happen naturally on both sides.
💼MeetingsIn Thai meetings, decisions happen fast and people talk over each other. Captio AI captions every speaker as they talk, so you never miss a decision or a question directed at you.
🎓LecturesThai lecturers speak quickly, cover complex material, and rarely repeat themselves. Captio AI gives you a live transcript of everything said, so you can follow the content instead of straining to hear it.
🏥Doctor AppointmentsDoctors speak quickly in Thai and use clinical language that's easy to mishear. Captio AI shows you everything they say in real time, so you can follow your diagnosis and ask the right questions.
🤝Job InterviewsMissing a question in a Thai interview means answering wrong or asking for a repeat. Captio AI shows you every word the interviewer says, so you can focus entirely on your answer.
📱Phone & Video CallsThai phone and video calls are harder to follow than in-person conversations. No lip reading, often poor audio quality. Captio AI captions whoever is speaking in real time, so you do not need to ask for repeats.
👥Group SettingsIn Thai group conversations, multiple people talk at once and the thread moves fast. Captio AI keeps up with whoever is speaking, so you can follow without losing where the conversation is going.
🍽️Restaurants & CafesBackground noise in Thai-speaking restaurants and cafes makes speech hard to follow. Captio AI focuses on whoever is speaking to you, so you can have a real conversation through the noise.
✈️TravelingIn Thai-speaking cities, airports, and hotels there is no margin for mishearing. Captio AI captions speech in real time, so you can navigate confidently wherever you go.
🎤Conferences & EventsAt Thai conferences, speakers are far away, acoustics are unpredictable, and you cannot ask for a repeat. Captio AI gives you a live transcript of every speaker, so you can follow the full event from any seat.
📺TV & MediaBuilt-in subtitles on Thai TV, films, and videos are often wrong, delayed, or missing. Captio AI captions whatever is playing in real time, so you are not dependent on what the content provides.

Supports Standard Thai (Central Thai) and regional varieties across Thailand.
Phasa Klang dialect
Central Thai (ภาษากลาง) — the Bangkok variety that serves as the standard for broadcasting, education, and formal communication. Used as a second language in formal contexts by most Thai speakers. Captio AI handles Phasa Klang with full accuracy, displaying captions in native Thai script.
Kham Mueang dialect
Northern Thai (คำเมือง) — spoken in Chiang Mai, Chiang Rai, Lampang, and across the old Lanna kingdom region by around 6 million people. Has distinct tones, vocabulary, and its own historical script. Captio AI handles educated Kham Mueang speech accurately; very heavy dialect features may occasionally reduce accuracy.
Phasa Isan dialect
Northeastern Thai (ภาษาอีสาน) — spoken by around 20 million people across the Isan region. Closely related to Lao and significantly different from Standard Thai in vocabulary, tones, and grammar. The most widely spoken regional Thai variety. Captio AI handles Phasa Isan in standard conversational form.
Phasa Tai dialect
Southern Thai (ภาษาใต้) — spoken across 14 southern provinces from Chumphon to the Malaysian border. Has 7 tones — more than any other Thai variety — plus rapid speech and distinct intonation. The regional Thai variety Central Thai speakers find hardest to understand. Captio AI handles educated Southern Thai speech accurately.
Captio AI supports 60+ languages

Gone the moment it ends
Captio AI processes your Thai audio in real time and discards it immediately. Nothing is recorded. Nothing is kept.
Not a product
Your conversations are not something Captio AI sells, shares, or monetizes — to anyone, for any reason.
Not used to train anything
What you say in a Thai doctor's appointment or job interview never ends up in a training dataset. Not ours. Not anyone else's.
Hearing accessibility for Thai speakers
Thailand's deaf community uses Thai Sign Language (TSL), which was officially recognized in 1999. TSL developed with significant influence from American Sign Language through historical educational exchange programs in the mid-20th century. Thailand has around 300,000 deaf people, and TSL serves as both their primary language and a marker of cultural identity.
A 2007 law gives deaf people in Thailand the right to sign language interpreters, medical services, and education free of charge. In practice, the availability of trained interpreters is uneven. Many people in Thailand, particularly outside Bangkok and major cities, still lack consistent access to professional interpretation.
For hard of hearing Thai speakers, hospitals in Bangkok have better support than in rural provinces. Thai medical vocabulary moves quickly in consultations. Captio AI captions spoken Thai in real time, displayed in native Thai script, in the situations where formal interpreter access is not available.
