# Prepares and trains a Sphinx acoustic model using
# WSJ0 and WSJ1 training data.
#
# Paramters:
#   $1 - "wsj_si84"   to train just on SI-84 data (default)
#        "wsj_si284"  to train just on SI-284 data
#        "wsj_all"    to train on all WSJ training data
#   $2 - how many Gaussians to mix up to (continuous models), 32 default
#   $3 - number of Gaussians to start training from (0 for new run)
#   $4 - "skipinit"   if we want to just train and eval using a 
#                     different training data subset (you need to
#                     have previosly run without this option)
