I updated errors.
I got new errors like:
ERROR ([5.4.86~1-9b90c]:OnlineTransform():online-feature.cc:421) Dimension mismatch: source features have dimension 117 and LDA #cols is 361
Probably the mfcc.conf that you are using is not the same as was used to train the model. Also, are you using pitch features in your model?
Thank you for your advice! I fixed mfcc config file and it seems to solve this errors! (I did not use pitch feature!) thanks!!

Greetings!!!
I am facing some problems while building kaldi with gstreamer. Here I am attaching the worker.log file. Please give some idea to resolve it.

ERROR ([5.4.176~1-be967]:ReadConfigFile():parse-options.cc:469) Cannot open config file: opt/models/english/tedlium_nnet_ms_sp_online/conf/mfcc.conf
Please check there is opt/models/english/tedlium_nnet_ms_sp_online/conf/mfcc.conf
.
config for high-resolution MFCC features, intended for neural network training
Note: we keep all cepstra, so it has the same info as filterbank features,
but MFCC is more easily compressible (because less correlated) which is why
we prefer this method.
--use-energy=false # use average of log energy, not energy. --num-mel-bins=40 # similar to Google's setup. --num-ceps=40 # there is no dimensionality reduction. --low-freq=20 # low cutoff frequency for mel bins... this is high-bandwidth data, so
there might be some information at the low end.
--high-freq=-400 # high cutoff frequently, relative to Nyquist of 8000 (=7600)
@aonotas Thank you so much for your quick reply The above pasted text is in my mfcc.conf file.
instead of test i am using opt. I am following the below link for reference. https://medium.com/@nikhilamunipalli/simple-guide-to-kaldi-an-efficient-open-source-speech-recognition-tool-for-extreme-beginners-98a48bb34756

Hi, @alumae Is there a way to enable pitch features? I was expecting something like pitch-config=pitch.conf
which is not provided yet.
Thanks.
(updated) Hi! I'm beginner of Kaldi and Gstreamserver. I have a trained Kaldi model with NNet3 on CSJ corpus. I tried to run NNet3 with Gstream server. But I got following errors. Could you give me some advice?
Using
steps/online/nnet3/prepare_online_decoding.sh
, I convert kaldi model for online decoding.and create .yml file (
$ vim sample_csj_nnet3.yaml
)and run gstrem worker like
Then I got following error messages:
