batch_decode.sh

[Anati]

This script for batch_decode.sh :

sphinx3_decode -cepdir feat -ctl etc/kacst_test.fileids -dict etc/kacst.dic
-fdict etc/kacst.filler -hyp rec_results.txt -hypseg rec_results_seg.txt -lm
etc/kacst.lm.DMP -mdef model_architecture/kacst.1000.mdef -mean
model_parameters/kacst.cd_cont_1000_8/means -mixw
model_parameters/kacst.cd_cont_1000_8/mixture_weights -tmat
model_parameters/kacst.cd_cont_1000_8/transition_matrices -var
model_parameters/kacst.cd_cont_1000_8/variances

i swap kacst.cd_cont_1000_8 with kacst.cd_cont_1000_4 and the error same !

[Anati]

plz tell me if i should put my data base path in sphinx 3.cfg file

If you have issues you can always share your whole database folders so your
problem could be reproduced. You can pack the folder in archive, upload to a
public file sharing resource and give us a link.

plz tell me if i should put my data base path in sphinx 3.cfg file

I'm not sure what "sphinx 3.cfg" file you are talking about. I'm not aware
about such file in CMUSphinx setup.

Hello

Your batch_decode.sh script doesn't work because it has invisible control
symbol in the end. Its a Windows-style newline \r or hex code 0xd 0xa. You
need to remove it to make it work. You can do that with the following command:

dos2unix batch_decode.sh

then you can run it as usual

sh ./batch_decode.sh

It will work and produce results as expected

For more details see the tutorial http://cmusphinx.sourceforge.net/wiki/tutor

Mr.nshmyrev

I created anew folder caled 949 and put a recorded in it then i excute sh
./batch_decode.sh

but a result was :

INFO: utt.c(74): Processing: 949-1
INFO: feat.c(1176): At directory feat
INFO: feat.c(993): Reading mfc file: 'feat/949/949-1.mfc'[0..-1]
SYSTEM_ERROR: "pio.c", line 450: stat(feat/949/949-1.mfc) failed; retrying...
; No such file or directory
ERROR: "feat.c", line 1002: Failed to open file 'feat/949/949-1.mfc' for reading: No such file or directory
FATAL_ERROR: "utt.c", line 120: Cannot read file 949/949-1. Forced exit

why this error and why the system didnt generate feat files ??

[Nickolay V. Shmyrev]

Before decoding you need to extract feature mfc file from the audio file. You
can do that with sphinx_fe command.

You did not do that and it says the file is missing. The message should give
you a hint.

I dont know , but i choose alpha 0.97 and this error is appeared

SYSTEM_ERROR: "sphinx_fe.c", line 125: Failed to open (null); Bad address

Why ?

[Anati]

What is the argumant for sphinx_fe?
and what is the form to put path of wav file ??

[Nickolay V. Shmyrev]

What is the argumant for sphinx_fe?
and what is the form to put path of wav file ??

sphinx_fe -i file.wav -o file.mfc -argfile etc/feat.params

or

sphinx_fe -c file.fileids -di wav -ei .wav -do feat -eo .mfc

there are other arguments to append. You can get the list if you run sphinx_fe
without parameters.
