About this app

WatPhasa helps you speak Thai the way Thai people actually speak it — with the right pronunciation, the right tone, and the right words for your gender.
Speak Thai with confidence
Whether you're travelling to Thailand or building a life with a Thai family, WatPhasa gives you real, practical phrases you'll use every day — not textbook Thai.
AI-powered pronunciation scoring
Record yourself speaking Thai and get instant feedback on your pronunciation. WatPhasa uses advanced AI to analyse your speech and show you exactly where to improve.
Hear real Thai voices
Every phrase comes with native Thai audio so you can hear exactly how it should sound before you try it yourself.
Personalised for you
Thai is spoken differently depending on whether you're male or female. WatPhasa automatically adjusts phrases to use the right words for you — ผม/ครับ or ฉัน/ค่ะ — so you always sound natural.
Build a daily habit
Short daily practice sessions keep you improving consistently. Track your streak, revisit favourites, and watch your Thai get better every day.
300+ real-life phrases across 10+ categories
