Drawing fst graph of HMM

[willy8...@gmail.com]

Hi, I've trained a HMM-model by DNN using Kaldi toolkit, which is in the form of mdl file.
I wonder that whether it's possible to draw its finite state transducer graph from this model file for I need to take a sight into it.
Thanks.

you can use fst-draw.and you can see http://www.openfst.org/.

Well, that may help if .mdl file is a formal fst format file, but it's not.
That's why I want to ask for some advice to draw fst of model directly from it.

There is no point trying to draw an FST of the model - due to context effets, it would be a huge mess with hundreds of thousands of arcs and would give you no useful information.  I suspect the picture in your mind of what the FST would look like is very different from the reality.
