That's OK -- there are random effects in feature extraction due to dithering.
I have a kaldi gstreamer server setup. My setup runs Aspire nnet3 model (http://kaldi-asr.org/models/m4). Sometime when I am running the same call to my server, I get different results. The results are not completely different, but one of: noise/laughter or the actual result. (at the following example, my java decoder that stream a file to my kaldi gstreamer server)
What can cause such behavior?
