NAME

mkgshmm - convert monophone HMM to GS HMM for Julius

SYNOPSIS

mkgshmm monophone_hmmdefs > outputfile

DESCRIPTION

mkgshmm converts monophone HMM definition file (hmmdefs) in HTK format to a special format for Gaussian Mixture Selection (GMS) in Julius. GMS is an algorithm to reduce the amount of acoustic com- putation with triphone HMM, by pre-selection of promising gaussian mixtures using likelihoods of corresponding mono- phone mixtures. For more details, please consult related documents and papers

EXAMPLE

(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 foo.jconf -gshmm gshmmfile
