Rescoring query

[Nayeem]

Sir,

I have a language model (long span LM) that gives a sequence of 
probabilites for each word in a test  sentence. I cannot write this 
language model in arpa format. The query I have is, can I integrate these 
probabilites into a lattice or N-best lists for rescoring.

In detail the problem is, for a test sentence/utterance I can get a 
lattice or N-best list  generated using HTK.  For the same sentence 
(assuming I have the transcription) I can get the probabilities for each 
word in the sentence using my long span LM. How can I integrate/rescore 
the lattice or N-best list using the tools in the SRI-LM toolkit. What 
tools and options should I use.

Kindly help me in this regard. Any suggestions is welcome.

Any pointers to important papers on rescoring is also requested.
