It seems to me that in exercises the voice speaks with an accent. Is it true? Listen is hard to me, and I am native Russian speaker.
The voice speaks with a standard Moscow/St.Petersburg accent. If you belive that the absence of accent exists, this is probably what you would call speech without an accent.
I do not hear this accent in the Saint-Petersburg. I live in Saint-Petersburg all my live.
Sound like a plain standard pronunciation to me. Professional voice talents usually sound about like that—on radio, on TV, in films and audio books, in transport announcements. The rest depends on your own pronunciation,
But perhaps one skill I disassembled with hard , said there is "так" or "как".
Давайте! :) Возможно, но в одном навыке я с трудом разобрала, голос произнес "так" или "как".
My only complaint would be the speed at which she talks. Normal talking I can differentiate the words but I cannot with her. However, my wife (she is from the Ukraine) had no difficulty understanding her.
