Pinyin tones pronunciation cheat sheet I've just started taking Chinese lessons, and I've been trying to find a "cheat sheet" for pinyin pronunciation. All the sites I've found is either incomplete (only having some tones), only having the pronunciation as a description or comparison to English.

What I'm looking for is basically a table that looks like this:

ā ē ī ō ū ǖ
á é í ó ú ǘ
ǎ ě ǐ ǒ ǔ ǚ
à è ì ò ù ǜ
a e i o u ü


Where I would be able to click on any one of them and hear the pronunciation. Sounds so simple, but I've just not been able to find one...
Here are my two favorite browser-based pinyin cheat-sheets:

Whereas the site linked to in the currently top-ranked answer (lost-theory.org - a nice, new find for me, BTW) uses big, lossless .wav files (which also unfortunately seem to include a great deal of background noise), the sites I link to above use compressed mp3s, so I think you'll have a vastly easier time using them on a slow connection. Enjoy!
