Admittedly, I suffer from severe hearing loss and have hearing aids - which don't compensate 100% - but am I the only one who has trouble with the pronunciation of unstressed vowels? All I could hear the speaker saying was "dyevoshka" - not "dyevochka" or "dyevooshka." I first learned Russian 45 years ago and I don't remember any of my (5 different) teachers speaking this poorly.
This text-to-speech software definitely has its limits! Apparently though, it's what allows for the speech to be slowed down in that "turtle" option in listening exercises?? (This is what I've read on the Irish forum. The sentences in Irish were recorded by a person who's a native speaker because there's no text-to-speech software for Irish. But this is why there's no "turtle"option.) If you want to hear a particular word pronounced by real people, I recommend trying the Forvo website for samples.
