[Kaldi-developers] How to redo recognition on new lattice

[Anna S. <an...@co...>]

Dear Kaldi developers,

I am trying to combine Kaldi recognition results (in form of the result 
lattice that is output when decoding with gmm-latgen-faster) with 
situation dependent world knowledge which can also be represented as a 
lattice. For this I implemented a 'merging' of two lattices to produce a 
combined structure that is a lot smaller than HCLG, but should still 
contain the correct recognition hypothesis for the current sound file.
We would like to redo the recognition on this structures to reduce WER 
further.

So, my question is:
Using Kaldi, how would it be possible to rerun the recognition on this 
new, combined lattice? There exists one unique combined lattice for each 
wav file in our test corpus since the situational knowledge is different 
for every file.

Thank you very much for your help and all the best,

Anna Schmidt
