Code: Create Prototype HTK HMM

Posted on November 16, 2006

One of the things that can be annoying about using HTK is creating the prototype HMM files. 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.

Hey, I found this to be very helpful. Thanks! A comment, though – the newline characters in the printf() statement (\n) are being displayed as simply “n” on this page. Just thought I’d let you know.

Thanks for that Ryan. I’ve changed it to a download link that should work better.
