Hi,Heiga

In HTS 2.0,duration is modeled by Gaussion distribution.Now I am attempting to model it with Gamma distribution.

I read the source code according to the paper,"Duration Modeling For HMM-Based Speech Synthesis".However I couldn't find out how the duration is modeled by Gaussion distribution.It seems it doesn't matter much that which distribution is used to model the duration.

Best Regards!

I don't know.
, , , , and have been defined by HTK.
Only was added by HTS.
No information about DurKind is provided in HTKBook.

# We can guess the meaning of POSSIOND and GAMMAD.

Currently DurKind is not used in any HTK/HTS routines.
So changing to has no effect.
