# This script produces CTM files with confidence scores
# from a decoding directory that has lattices
# present. It does this for one LM weight and also supports
# the word insertion penalty.
# This is similar to get_ctm_conf.sh, but gets the CTM at the utterance-level.
# It can be faster than steps/get_ctm_conf.sh --use-segments false as it splits
# the process across many jobs.
