I have studied and speak four languages (Thai being the fourth), and this is BY FAR the best tool I have ever used. The title doesnt do it justice as it is so much more than a dictionary…even much more than a talking dictionary. The program includes helpful features like "Find Words Inside" (to quickly break down Thai compounds to roots), and an entire instruction book is included in the Help section explaining everything about Thai including pronunciation, spelling, grammar, and even the dreaded Thai classifier. And they even offer icons to help understand which words are "spoken" (colloquial), "formal," "used for or by royalty," "used for or by monks," and even "obscene" (e.g. the "bad words" are all included). Before I bought this, I was a little put off by the price tag, but having owned it for many months I think it is the best Thai tool available! I wish they would make this for Spanish and French, too!!!
UPDATE: THANK YOU FOR THE LONG AWAITED UPDATE … VERY NICE!
