The tone of any syllable in Thai is determined by four factors:
- The class of the initial consonant, low, mid or high
- Whether the syllable is live or dead
- Whether the vowel or diphthong is long or short
- Whether there is a tone mark or not, and if there is, which of the four tone marks it is.
