This set of language tapes is a good introduction to Thai. For those familiar with Pimsleur-method tapes, the format and execution are identical to lessons from other languages. I have previously used the German I set with some success, and I am pleased with the Pimsleur Thai. The method of teaching and learning is very effective, given in approximately 30-minute lessons. You begin learning simple phrases, repeating after the speakers, and answering questions. This is much better than some tapes I have tried to use, which begin with (impossible-to-learn) recitations of the Thai alphabet and such. Using the Pimsleur, you gradually develop a conversational ability. My only complaint regarding the product is that it is too short, and a complete Thai I course (30 lessons) is not available. The Compact edition is too short to develop any more than a very basic level of conversational ability. On a positive note, my wife is Thai and she reports that the accents are good (native Thai speakers). That is the second best thing about Pimsleur Audio tapes (for any language) - you develop great pronunciation by repeating after native speakers. The best thing about the tapes is that the format is conducive to learning the language well.
