denial, yes, there are hard consonants in Russian, although usually theyґre not a problem. Russian "o" sounds like "a" when it`s unstressed...like in English the word "computer," the accent/stress is on the PU - comPUter - and if it were a Russian word you`d "reduce" the "o" to "a" and pronounce it like cahmPUter instead of cohmPUter.
All unstressed vowels reduce in Russian, but "o" is the one that`s most important, because it`s very obvious and very bad if you don`t - people won`t be able to understand what you`re saying.
I donґt know of a good audio dictionary, sorry. If I hear about one I`ll let you know.
Thanks for your comments
