# To be run from one directory above this script.

# Note: when creating your own data preparation scripts, it's a good idea
# to make sure that the speaker id (if present) is a prefix of the utterance
# id, that the output scp file is sorted on utterance id, and that the
# transcription file is exactly the same length as the scp file and is also
# sorted on utterance id (missing transcriptions should be removed from the
# scp file using e.g. scripts/filter_scp.pl)
