Khuu Sawm · Speak Thai
คู่ซ้อม
khûu sáwm — your sparring partner
Most Thai apps teach you words. This one makes you use them — out loud, in a scene, with someone talking back.
How it works
Pick a scene — ordering at a street stall, arguing with a landlord about a broken air-con, explaining a delay to your boss — and start talking. The app plays the other person in that scene, in character, and answers in Thai the way a real Thai person would. Then it grades what you said.
๑
35 situations you will actually be in, each with a goal — order one dish, say how spicy, ask the price, pay.
๒
Speak and the app transcribes your Thai. Or type it, if you are somewhere you cannot talk. Both are graded the same way.
๓
A score out of 100, your sentence rewritten, and a note on exactly what changed and why.
A real correction
You are at a street food stall. You have ordered, and it was close — but not quite how a Thai speaker would have said it.
You said
เอาผัดกะเพราหมูหนึ่งจาน
เอาผัดกะเพราหมูหนึ่งจานครับ
Good job ordering! Just add ครับ at the end since you're male.
You forgot the polite particle ครับ, which male speakers should use at the end of sentences.
The scenes
From getting fed and getting home, up to disagreeing with a senior colleague without losing face.
Get fed, get home, be polite.
The week you actually live.
Talking to people, not at them.
The admin that needs real Thai.
Register, hierarchy and face.
Where fluency actually lives.
The details that matter
Thai politeness particles agree with the speaker, not the listener — so an app that guesses will teach half its users the wrong ones. Tell it which you use, and every correction follows it.
Your speech is transcribed to text, and the text is what gets graded. The app never analyses your audio. What it scores is word choice, grammar, particles and register — whether what you said was the right thing to say.
Every Thai line the character says can be played aloud, with a slow-speech option and a sound-out view for the script you are still learning.
No account, no sign-up, no ads. Nothing to create before you start talking.

Questions
No. Your speech is transcribed to text, and the text is what gets graded — the app never analyses your audio. The score covers word choice, grammar, particles and register: whether what you said was the right thing to say, phrased the way a Thai person would phrase it.
No. There is no account, no sign-up and no ads. Nothing to create before you start talking.
Yes. Thai politeness particles agree with the speaker rather than the listener, so you tell the app which you use and every correction follows it. An app that guesses teaches half its users the wrong particle.
The five Survival scenes are free and stay free. The other thirty come with a subscription at $1.99 a month, with a fair-use ceiling of 400 practice turns a month — around 30 full scenes.
Yes. Talk and the app transcribes your Thai, or type it if you are somewhere you cannot speak. Both are graded the same way.
The Survival level assumes almost nothing — ordering food, taking a taxi, paying at the 7-Eleven. The six levels run all the way up to defending an opinion, telling a long story, and handling a difficult emotional conversation.
Requires iPhone with iOS 16 or later.
