# This script normalizes the GlobalPhone Portuguese transcripts that have been
# extracted in a format where each line contains an utterance ID followed by
# the transcript, e.g:
# PO001_64 o grupo na~o mencionou ataques a bomba
# The normalization is similar to that in 'gp_norm_dict_PO.pl' script.
