The intonation on "bardzo" sounds very convincing :)
Is it to be considered normal, that the 'u' in 'usługa' is not pronounced or is that just a mispronunciation of the computer voice once again?
I hear it. Anyway, if it's written, you should hear it - the exceptions could be counted on your fingers.
I think this problem occurs during the slow pronunciation: the initial "u" of "usługa" is very truncated. The normal speed pronunciation seems fine though.
