[Kaldi-developers] Word insertion penalty in the decoder

[Augusto H. H. <au...@li...>]

Hello everyone,

I would like to have a word insertion penalty option in the decoders. I am aware of the `lattice-add-inspen’ program, but I think it would be nicer if this option was inside the decoder core.

In a recent discussion on the forum, Daniel mentioned that

This interests me. Would anyone care to elaborate? I’m thinking of the BiglmFasterDecoder class. Is the PropagateLm method a good place to add this graph cost?

Thanks
