# 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-$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) 
#         - "skiptrain"  skip the training portion of script
#         - "skipeval"   skip the evaluation portion of script
