Currently HTS doesn't include any tools to perform Viterbi alignment with HSMMs. 
Internally we have a WFST-based decoder for HSMMs.  But it's not open.  Simon 
King has shown an approximate solution for this problem.  Please refer to 
hts-users:01140-01143 for details.  You can find them in hts-users ML archive 
(http://hts.sp.nitech.ac.jp/hts-users/spool/2008/threads.html).

Once state-level alignment is obtained, you can generate cepstrum and F0 
parameters with this state alignment using HMGenS with -s option.
