<div dir="ltr"><div>Hello,<br>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:<br>
1- Extract lattices from the various recognizers (With HTK in my case)<br>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.<br>
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).<br>4- And repeat the merging step (3) using the previous mesh to initialize the next lattice.<br>
<br>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.<br>Thanks a lot in advance,<br><br></div>Cristina</div>
