Just a small footnote :

we (the lab I'm working in) have faced some problem with this : if you 
ever need to increase the number of streams in your model (e.g. to 
increase the dimensionality of log f0), be aware that default 
(HTS-patched) HTK accepts only 8 streams maximum (5 if non-patched).

This can be set to 10 streams by changing SMAX (in HShell.h) HTK's 
internal config variable and then recompiling HTK (then, stream's index 
go from 0 to 9 I think) but HTK seems to not support index above 9, 
therefore if you need more streams, you'll have to make some changes to 
the core code (not too difficult though, I don't have these changes 
right now, but if you need them I'll try to find them)

Anyone, please feel free to tell us if I'm wrong about this,
