Learn Thai words you'll actually use.

No. Every word and sentence has a phonetic spelling with tone marks next to the Thai script, so you can learn to speak and understand first while the script becomes familiar. When you want to practice reading, switch to Thai → English.

It uses spaced repetition. A word you know comes back after 1 day, then 3, then 8, then about 20 days, and on, so you see it again just before you’d forget it. Each day, Review gathers the words due in every deck, and a word is mastered after three right answers in a row.

Each syllable of the phonetic spelling is colored by its tone: mid, low, falling, high or rising. The tone marks stay (à low, â falling, á high, ǎ rising, no mark for mid) and screen readers say the tone, so color is never the only signal. You can turn the colors off in Settings.

Words and example sentences are spoken by your device’s built-in Thai voice, at normal or slow speed. The listening stories are recorded with natural-sounding Thai neural voices from Microsoft Azure, a different voice for each character, men and women. They’re computer voices, not recordings of people.

Yes. Everything works offline, the listening stories included: their recordings come with the app. The only exception is the optional speaking check, which uses your phone’s speech recognition and needs the network on most phones.

No. There’s no account, no ads, no in-app purchases and no tracking, and your progress stays on your device. The App Store privacy label is “Data Not Collected”.

The app tells you and shows how to add one. On iPhone and iPad, go to Settings → Accessibility → Read & Speak (or Spoken Content) → Voices → Thai. Pronunciation, tone training and the listening stories all use it.
