I think the first thing any researcher probably does is write a quick little program to generate a prototype from a number of parameters. So here’s my version to save you — the person who found this page on google — the trouble.

MakeHMMPrototype, written by David Dean, 2004

Generates a forward only, diagonal covariance HMM prototype

usage:
   MakeHMMPrototype name parameterkind vectorsize numberstates mixturesperstate \
                [ streamcount vecsize1 ... vecsizeN ]

   name             : name of hmm (eg. prototype)
   parameterkind    : parameter kind (eg. MFCC_0_D_A)
   vectorsize       : size of feature vector
   numberstates     : total number of states
   mixturesperstate : number of mixtures per state
   streamcount ...  : multiple-stream support
                      (vecsize1 + ... + vecsizeN = vectorsize)

You can download the c code to compile to your favorite platform here.
