[hts-users:01819] Re: HTS voice built with Festvox 2.1 - HHed failure during duration model clustering

[Esther Klabbers <klabbers@xxxxxxxxxxxx>]

I wish there was more information available on how to use files  
generated in HTS-demo in Festival. I have been able to run HTS-demo  
for the SLT voice but when I compare the output .win, .inf and .pdf  
files they are different than the ones distributed in the  
nitech_cmu_slt_arctic_hts/hts directory.
- For one the standard HTS-demo script produces mgc.pdf instead of  
mcep.pdf. Are these the same but with a different name? Or are they  
different. If they are different how can you change the scheme files  
for Festival to work with the different format.
- The .win files are ascii in HTS-demo but something else in the  
festival voice. How do you convert these?

Thanks, Esther Klabbers
