I recently visited Indonesia, and people who spoke Indonesian were surprised how good my Indonesian pronunciation was. Apart from some food, I didn't understand a word of Indonesian, but in Indonesian, pronunciation is pretty much phonetic. Just say what it says, and you can't go wrong. Unless you're a native English speaker, in which case all the crazy mangled pronunciation you've grown up with gets in the way.
A lot of languages from totally different corners of the world have agree on pronunciation, and have practically identical rules for it. A few exceptions, like English and French, seem to require mangling it beyond all recognition.
