nnet online decoding without ivectors

Open Umar17 opened this issue 6 years ago • 2 comments

Is it possible to use gst-kaldi-nnet2-online for a nnet model trained without extracting ivectors? It throws no error when I comment out ivector-extraction-config line in worker's configuration, but the decoded output is just junk. Is the problem is model without ivectors or something else?

Best Regards

It should be possible but I have never tried. Does the model work fine when decoding using Kaldi's native tools?

Yes. Decoding is fine with kaldi's decoding script. If I don't comment out ivector-extraction-config in configuration it raises: ERROR ([5.2]:Compute():nnet-compute-online.cc:55) Feature dimension is 113, but network expects 13
