There is no single standard for writing Thai in the Roman alphabet — phrasebooks, road signs, and tourist guides each follow a different system, and many just invent their own spellings. The romanization on this page uses a consistent IPA-based system that marks all five tones and distinguishes short from long vowels. The same word always gets the same spelling.
