[hts-users:02407] Re: Any easy way of getting an adapted model set?

Hello, Dr. Zen,

Your patch worked -- I obtained a non-diagonal covariance model set.

By the way, I suppose the patch needs to be further improved. Currently, in any of the three following cases, an adapted model set will be generated by the AX command of HHEd:

Case 1:
HTK Configuration Parameters[26]
  Module/Tool     Parameter                  Value
# HADAPT          SAVEFULLC                   TRUE
  HADAPT          SAVESPKRMODELS              TRUE
  .... (other 24 parameters)

Case 2:
HTK Configuration Parameters[26]
  Module/Tool     Parameter                  Value
# HADAPT          SAVEFULLC                  FALSE
  HADAPT          SAVESPKRMODELS              TRUE
  .... (other 24 parameters)

Case 3:
HTK Configuration Parameters[26]
  Module/Tool     Parameter                  Value
# HADAPT          SAVEFULLC                  FALSE
  HADAPT          SAVESPKRMODELS             FALSE
  .... (other 24 parameters)

This may be a problem especially when someone is going to generate an "adapted" HTS engine by both AX and CM commands. He may not want an adapted model set.

Thanks a lot for your kind help.
