Which language models were used to generate G.fst for the pre-trained Kaldi models

[lightalchemist]

Hi. I'm trying to do lattice rescoring using the kaldi-generic-en-tdnn_fl-r20190609 model.

To do that, I need G.fst corresponding to the language model used for training the above model, but it is not one of the files in the directory when I unzipped the above model.

May I know which language model was used to generate the above model so that I can generate it myself using arpa2fst? Is it one of the 3 english LM found at https://goofy.zamia.org/zamia-speech/lm/ ? If so, which is it?

In general, may I know which language model was used to generate the HCLG.fst files for the various english language models in the Kaldi ASR download page?

Thank you.
