Error in making MFCC features

[Sidrah Azhar]

Hi,

I have 23 speakers in total, 12 for training and 11 for test data. My data/local/train.spk2utt (Attached) file is in right format and data/local/spk2gender (Attached) has all speakers i.e train and test. But when i reach this piece of code

# Now make MFCC features.
# mfccdir should be some place with a largish disk where you
# want to store MFCC features.
mfccdir=${DATA_ROOT}/mfcc
for x in train test; do
 steps/make_mfcc.sh --cmd "$train_cmd" --nj $njobs \
   data/$x exp/make_mfcc/$x $mfccdir || exit 1;
 steps/compute_cmvn_stats.sh data/$x exp/make_mfcc/$x $mfccdir || exit 1;
done

The utils/validate_data_dir.sh gives me this error:

utils/validate_data_dir.sh: Error: in data/train, speaker lists extracted from spk2utt and spk2gender
utils/validate_data_dir.sh: differ, partial diff is:
1,12d0
< ahmed
< ayesha
< fatima
< iqra
< izza

< khatija
< laiba
< lozina
< mubarra
< muneeb
< shiza
[Lengths are /tmp/kaldi.2TxI/speakers=12 versus /tmp/kaldi.2TxI/speakers.spk2gender=0]

Any help is appreciated!

Thanks.

looks like you have a spk2gender file that's empty.  either delete it or create a valid one.

spk2gender in data/train directory is empty. But still why?

because in the spk2gender file, there are 23 speakers in total, while in the train.utt2spk, there are only 12 speaker, and kaldi expects these 2 files contain the same number of speakers.

i wrote a python scripts to remove the extra speakers in the spk2gender file, and pass the validate_data_test
