I can't hear this file.
I think you can try to train HMM without upsampling.
By modifying some part of HTS-demo/scripts/Training.in and 
HTS-demo_.../scripts/mkdata.in,
you can run the training script on 55000 Hz sampling.
If you want to use hts_engine for synthesis, defaults.h should also be 
modified.

I don't think so.
Some of my colleagues trained HMMs with less than 50 utterances.
Synthesized speech from these HMMs were intelligible.
(Actually, speaker of this experiment was very good.)

Oops, it's my mistake.
We'll fix it in the next release.
Thank you very much.
