Oh dear, I couldn't hear any difference.
But one thing that I definitely CAN hear which I don't think sounds very nice, is that some Belarussians say "х" or "h" in places where there is a "г".
For example, "загореть" , they say "заhореть". I learnt the word from a Belarussian when I was there, and I actually checked the dictionary for захорить or something like that when I checked it up! LOL.There were several words like this.
I was told that this is a somewhat "uneducated" way of speaking Russian in Belarus.
Nothing strange about that at all, there are a million such nuances to English... But Russian is said to have "no accents", but I would definitely call this way of speaking a local accent.
