Here are some flash cards for learning Thai vowels. Click above for consonants and numbers. Scroll until you find some cards you don’t know yet, then click one to enter Slideshow mode.
    Vowel characters can be written to the left, right, above or below the consonant (which is represented by a black line).
    Most vowels have a long and short form, which is important since the length of the vowel usually changes the meaning of the word. Usually, one letter means “short vowel,” with double letters meaning “long vowel.”
    You can find many different ways that people have tried to render (transliterate) Thai into English letters. I’ve used a fairly standard method.
    There are three phonetic symbols (characters) you may not know:
- what looks like a backwards “c” is pronounced like “aw” in awful
- what looks like a backwards “3” is pronounced like “a” in bat
- what looks like an upside down “e” is like the “u” in under or the “e” in the
- what looks like a “u” with a line through it represents a distinctive Thai sound which some say is like “saying ‘oo’ while smiling,” or “the sound you make when you step in something yucky”!
    The other renderings are more obvious:
“a” as in father
“i” as in lip
“ii” like “ee” in bee
“u” as in duty
“e” as in egg
“o” as in wrote
    Sometimes vowel sounds are combined, which are pretty easy to figure out; for example “ai” is a combination of “a” and “i,” and makes a long “i” sound as in the word “line.”
