# This script normalizes the GlobalPhone Polish transcripts that have been
# extracted in a format where each line contains an utterance ID followed by
# the transcript, e.g:
# PO007_8 Aktualny sekretarz generalny PS Franc2ois Hollande pozyskal1 jednak wie~kszos1c1
# The normalization is similar to that in 'gp_norm_dict_PL.pl' script.
