I know that there are tons of different accents. But I really want to sound less Russian and more American (love the US accent).
Since I'm going to record podcasts, this is a bit of a problem :)
You probably should look at the 'Mid-Atlantic' accent as a goal.

(For what it's worth, I like the Russian accent. But a Mid-Atlantic accent has more marketability.)
