import csv
import sys

'''
usage:

create the following directories:
LDCdata/features_<feature_type>/MA
LDCdata/features_<feature_type>/GE

from LDCdata directory:
python generateFilenames.py <wavfilenamelist>.scp <feature_type> <language>

--
ex.
LDCdata/features_fbank/MA
LDCdata/features_fbank/GE

python generateFilenames.py germanwav.scp fbank german

--

output (2 .scp files in LDCdata/features_fbank):
LDCdata/features_fbank/germanwav_wav_fbank_files.scp --> contains wav and fbank file paths
LDCdata/features_fbank/germanwav_fbank_files.scp --> contains fbank file paths

Note: paths from LDCdata

--
running HCOPY:

this should work...but...

(from LDCdata directory)

HCOPY -C fbankcconfig.txt -S features_fbank/german_wav_fbank_files.scp
