Hello Yintan

Actually I have researched and know very well about 3 different sets of phonetics.  These sets come from people who are world leaders in transcribing Thai into English.  The pronounciation I have offered above is from Benjawan Poomsan Becker and it is spot on.  This work has been going on for a long long time and is far superior to the IPA system (which 99% of people are not familiar with anyway) and superior to the RTGS system (outdated but still used unfortunately) because it has tonal marks and uses only English letters.

The pronunciation I offer is a big improvement on what is out there at the moment and it is something that english speakers can follow easily.
