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.
(1) Prepare a monophone model which was trained by the same corpus as target triphone model.
(2) Convert the monophone model using mkgshmm.
(3) Specify the output file in Julius with option "-gshmm"
