Name

mkgshmm — convert monophone HMM to GS HMM for Julius

Synopsis

mkgshmm {monophone_hmmdefs} > {outputfile}

Description

mkgshmm converts monophone HMM definition file in HTK format into a special format for Gaussian Mixture Selection (GMS) in Julius.

GMS is an algorithm to reduce the amount of acoustic computation with triphone HMM, by pre-selection of promising gaussian mixtures using likelihoods of corresponding monophone mixtures.

EXAMPLES

(1) Prepare a monophone model which was trained by the same corpus as target triphone model.

(2) Convert the monophone model using mkgshmm.

% mkgshmm monophone > gshmmfile

(3) Specify the output file in Julius with option "-gshmm"

% julius -C ... -gshmm gshmmfile
