Cannot find utterance id KWS

[aliiire...@gmail.com]

Hi I'm afraid to ask this

I want to run KWS code in FARDAT dataset but in log output said: "Cannot find utterance id".

what's wrong?

that would mean something is wrong with the file

 data/kws//utter_id

it should contain lines such as 

007_1_43 1

007_1_44 2

and so on (the numbers will most probably be different)

Hi, Thanks

I change this code

local/kws_data_prep.sh

line 39

cat $datadir/wav.scp

to 

cat $datadir/stm

that's run, correctly(maybe!). 

where is "lattice archive" say in "kws_data_prep.sh"?

for compute-atwv how can create "ref-rspecifier/hyp-rspecifier"? handly or have a function?

I think you have some very old version of kaldi or damaged copy of it 

see

https://github.com/kaldi-asr/kaldi/blob/master/egs/babel/s5d/local/kws_data_prep.sh#L39

the line 39 does not contain that statement at all.

i used WSJ 

https://github.com/kaldi-asr/kaldi/blob/master/egs/wsj/s5/local/kws_data_prep.sh#L39

and I want to used babel in future.

please tell about, How can create "ref-rspecifier/hyp-rspecifier"? handly or have a function? 

[Jan Trmal]

OK, I'm not familiar with that setup -- in general, the names of the lattices will be primarily driven by the utterance names (i.e. you should use the segments file).

The wav.scp use will be valid only in cases when you have single utterance per file (which might be the case for WSJ, but I'm simply not sure enough to argue).

ad compute-atwv -- if you run the command without any parameters, it will print a fairly extensive info.

the file being <ref-rspecifier> is your reference. You will have to generate it by hand or write your own script for that. There is a "cheat-script" for cases where the reference is in form of the rttm file, but that script needs F4DE installed and on overall it's easier to generate the reference by "hand".

the file being <hyp-rspecifier> contains your hypotheses about the location of the individual keywords. That file gets generated during the keyword search.
