It is state of the art in speech recognition exactly because it uses neural networks. I helped develop its nnet3 neural network library and have published based on work I've done on it. No other open source toolkit is better than it right now, both because it has an open license (Apache2) and because it has a larger community than any other speech toolkit. You can see a lot of state of the art work done using Kaldi at Dan Povey's web page: http://www.danielpovey.com/publications.html http://www.danielpovey.com/publications.html He is the main maintainer of the project.
