The speaker pronounces "familio" incorrectly in many of the examples including this one. The accent should always fall on the next-to-last syllable. It should be fami-LI-o, not fa-MI-lio.
I don't know about the Esperanto pronounciation rules but at least in Spanish, the vocals i and u are "weak" and thus fuse with other vocals to one syllable. Then again this isn't Spanish...
