Sounds a bit like Kansai dialect, but it might just be that you barely hear the "u"s because they go by so fast.

Maybe "give each syllable the same length" would be a better way to put it than "emphasize each syllable". Since あいうえお (a i u e o) are syllables worth a single letter as apposed to the rest of the Japanese syllables, they are technically pronounced 2x longer than the vowels in the other letters (for example, if you give the syllables あ(a) and か(ka) the same length, the "a" in か would be half the length of just saying あ... does that make sense?)
