# This script normalizes the GlobalPhone German transcripts encoded in
# GlobalPhone style ASCII (rmn) that have been extracted in a format where each
# line contains an utterance ID followed by the transcript, e.g:
# GE008_10 man mag es drehen und wenden wie man will
# The normalization is similar to that in 'gp_norm_dict_GE.pl' script.
