Re: [Kaldi-users] data preparation problem

Hi,

I got another problem.

When I tried make_mfcc.sh to create the feats.scp files it did not work.

I checked the log file where it said some thing like:

compute-mfcc-feats --verbose=2 --config=conf/mfcc.conf
scp,p:exp/make_mfcc/train/wav_data.1.scp ark:-
ERROR (compute-mfcc-feats:Read():wave-reader.cc:144) WaveData: can read
only PCM data, audio_format is not 1: 65534
WARNING (compute-mfcc-feats:Read():feat/wave-reader.h:148) Exception caught
in WaveHolder object (reading).
WARNING (compute-mfcc-feats:LoadCurrent():util/kaldi-table-inl.h:232)
TableReader: failed to load object from 'test.wav'

Then I checked the attributes of my test.wav file which were as follows:
Input File     : 'test.wav'
Channels       : 1
Sample Rate    : 48000
Precision      : 24-bit
Duration       : 00:03:30.09 = 10084224 samples ~ 15756.6 CDDA sectors
File Size      : 30.3M
Bit Rate       : 1.15M
Sample Encoding: 24-bit Signed Integer PCM

Can you tell me what should I modify to my audio files. Thank you so much!

Best,

Zibo
