She definitely has an accent. When she says "для взрослых людей", her Л's do not sound Russian. In "взрослых" I hear a semi-soft Л instead of the proper hard Л, it sounds more like "взрослих". "Лю" in "людей" is a bit unnatural as well. But in "взрослых" it is highly noticeable.
Does anybody else confirm that?
