Haha thanks but seriously I'm ready, hit me with your upsidedown e's and your IPA!

Well upon looking at it further I found something which said;

In the first syllable before the stress the letter о sounds like а: акно... масква
Anywhere after the stress and more than one syllable before the stress: а & о sounds like "uh" or in IPA the upsidedown "e" (I realise this is not the term i'm just rolling with my train of thought). х"uh"рашо for example.
