[Kaldi-users] Dynamic LM classes

[Kirill K. <kir...@sm...>]

Not sure if this is exactly a kaldi question, but how dynamic classes could be handled in wfst HCLG composite transducer? There are more tricky cases when the lexicon also needs extension. I want an optimized approach, much faster than the whole HCLG composition from the ground up.

The Holy Book paper suggests the lazy composition, but I am not sure how to fit the determinization and adding self-loops into the picture (they did not explicitly use self-loops in the $H$ and instead assumed them in the decoder, but kaldi does, if I understand it correctly).
