What should be the input of compute-vad?

[Qianhui Wan]

Hi, I am trying to using compute_vad_decision.sh from /sid on my own dataset, but it failed and generated a log file which contains the usage of compute-vad as following:

# compute-vad --config=conf/vad.conf scp: data/train/split4/1/feats.scp ark,scp:directory/mfcc/vad_train.1.ark,directory/mfcc/vad_train.1.scp
# Started at Thu Sep 22 15:50:34 EDT 2016
#
compute-vad --config=conf/vad.conf scp: data/train/split4/1/feats.scp ark,scp:directory/mfcc/vad_train.1.ark,directory/mfcc/vad_train.1.scp

This program reads input features and writes out, for each utterance,
a vector of floats that are 1.0 if we judge the frame voice and 0.0
otherwise.  The algorithm is very simple and is based on thresholding
the log mel energy (and taking the consensus of threshold decisions
within a window centered on the current frame).  See the options for
more details, and egs/sid/s1/run.sh for examples; this program is
intended for use in speaker-ID.

Usage: compute-vad [options] <feats-rspecifier> <vad-wspecifier>
e.g.: compute-vad scp:feats.scp ark:vad.ark

It seems that the input for compute-vad should be scp:feats.scp ark:vad.ark instead of scp: feats.scp ark,scp:vad.ark,vad.scp. But in this way I won't get vad.scp.

Thank you so much if you could help me with this.

You put a space after "scp:".
