Dude - totally forgot to send you the damn links!

I've not managed to find any sites that play speech pronunciation (although there are a couple that have traditional chants available to stream so if they'd be any good let me know!)

this one (http://www.phantomranch.net/folkdanc/alphabet/hawaiian.htm) I found most useful personally, but there are others (aimed at tourists I think) like this (http://www.geocities.com/~olelo/o-pronunciation.html) and this (which also has a 'common words' section) (http://www.visitmaui.com/agents/pronounce.html)
