By the way, if you're not certain about words in the future, you can go to forvo and search for the word to find a recording by a human speaker, e.g.: http://forvo.com/search/%D0%B3%D1%80%D0%BE%D0%BC%D0%BA%D0%B8%D0%B9/ru/
Though I think sometimes people have trouble at first because they just haven't learned to hear the language yet. I often see people questioning the TTS when it sounds just fine to me. I suggest listening to a lot of stuff in Russian, maybe Russian music with text or recordings of Russian poetry, to get used to hearing the sounds of the language.
