[SRILM User List] Confusion network combination

[Cristina Guerrero]

Hello,
I am looking for information to accomplish confusion-network-combination
with the SRILM toolkit. I want to use the lattices generated by different
speech recognizers over the same speech segment. I haven't found a detailed
description of the steps to follow, so here is what I'm doing right now:
1- Extract lattices from the various recognizers (With HTK in my case)
2- Take one of these lattices as a starting point and convert it into a
confusion network MESH0 (lattice-tool -read-htk -in-lattice LATTICE0
write-mesh MESH0). *I know -posterior-prune can be applied to the lattice
before building the mesh for better results according to the "Finding
consensus.." paper.
3- Then, take the next lattice (LATTICE1) and merge it with the previously
generated mesh ( lattice-tool -in-lattice LATTICE1 -init-mesh MESH0
-write-mesh MESH1).
4- And repeat the merging step (3) using the previous mesh to initialize
the next lattice.

I'd really appreciate it if anyone could tell me if the described procedure
is the correct one, or provide me more information about it.
Thanks a lot in advance,

Cristina
