[hts-users:04394] Re: synthesis with STRAIGHT

[Rasmus Dall <R.Dall@xxxxxxxxxxxx>]

Hi Erica,

Another possible problem is the F0 extraction, even in the hts-engine  
tih no straight the F0 is very bad and there are several  
Voiced-Unvoiced errors. Have you tried tuning the F0 extraction and  
VUV parameters to fit your speaker?
