I graduated from Thammasat University,Thailand with a major in Linguistics. If the students want to speak Thai very clearly, I can teach you how to pronounce in the way of the 'phonetics' works.
Moreover, I've taught at least 4 students and at most 40. So, I have experiences of teaching. Just feel free to ask and enjoy my class! :))
Ps. I can teach online or in Ratchaburi province and BKK (someplace)
