[hts-users:01305] Questions of HMGens

["孙敬伟" <jwsun@xxxxxxxxxxxxxx>]

Hi,

   I have some questions about the usage of HMGens:

  

  

 USAGE: HMGenS [options] hmmList dmList labFiles...

 

 Option                                                    Default

 

 -a      Use an input linear transform                     off
 -b f    Mixture pruning threshold                         10.0
 -c n    type of parameter generation algorithm            0
          0: both mix and state sequences are given       
          1: mix sequence is given,                       
             but state sequence is hidden                 
          2: both state and mix sequences are hidden      
 -d s    dir to find hmm definitions                       current
 -e      use model alignment from label for pruning        off
 -f f    frame shift in 100 ns                             50000
 -h s [s] set speaker name pattern to s,                   *.%%%
         optionally set parent patterns                   
 -m      use model alignment for duration                  off
 -n s    dir to find duration model definitions            current
 -p      output pdf sequences                              off
 -r f    speaking rate factor (f<1: fast  f>1: slow)       1.0
 -s      use state alignment for duration                  off
 -t f [i l] set pruning to f [inc limit]                   inf
 -v f    threshold for switching spaces for MSD            0.5
 -x s    extension for hmm files                           none
 -y s    extension for duration model files                none
 -N mmf  Load duration macro file mmf                     
 -A      Print command line arguments         off
 -B      Save HMMs/transforms as binary       off
 -C cf   Set config file to cf                default
 -D      Display configuration variables      off
 -E s [s] set dir for parent xform to s       off
         and optional extension                
 -G fmt  Set source label format to fmt       as config
 -H mmf  Load HMM macro file mmf
 -I mlf  Load master label file mlf
 -J s [s] set dir for input xform to s        none
         and optional extension                
 -L dir  Set input label (or net) dir         current
 -M dir  Dir to write HMM macro files         current
 -S f    Set script file to f                 none
 -T N    Set trace flags to N                 0
 -V      Print version information            off
 -X ext  Set input label (or net) file ext    lab

 

  In option '-c', it is "1: mix sequence is given, but state sequence is hidden", but I think it should be "state sequence is given, mix sequence is hidden", right?

  In options '-e', '-m', '-s', what does "align" mean here,  what is the ture meaning of these options, could you  please explain them more explicitly?

  In options '-E', '-J', what does "xform" mean?

 

  Thank you, best wishes!
