I took a look at your wave files. I think I found part of the problem.
Let's use 'be' as an example. Open it up in utau's oto editor, oremo or a wave editor. This sample has 3 sections where the sound goes off the chart. That is called clipping. My understanding is that basically parts of the sound are too loud for it to store completely so it is getting cut off at the top and bottom parts of the wave. UTAU has to mess with this waveform further to do its job, so that is probably part of why the output sounds odd. Much of this wav file is cut off so I think the only thing you can do is re-record.
Wikipedia probably has a better description of clipping than I can give.
http://en.wikipedia.org/wiki/Clipping_(audio)I see another issue, but I am not experienced enough with UTAU to say how much of a difference it is making. You dont maintain the same pitch throughout your sample. In UTAU's oto editor you can see an orange line through the samples. I believe that is what UTAU thinks the sample frequency is. You cut off the big changes at the end of some of your samples, but 'be' still has a huge shift. I took a look at Teto's samples. They seem to have a short shift at the beginning like we do, but she keeps it in the first 0.1 secons of almost all her samples. After that first part she keeps the pitch pretty much even. I am rerecording a vb I am working on in attempt to imitate this aspect of her samples.
