[Kaldi-users] kaldi lattice

[Hao T. <lar...@gm...>]

Hi,

I'm trying to understand the last paragraph in the lattice page.

http://kaldi.sourceforge.net/lattices.html

What does it mean that the labels are pushed relative to the
transition-ids and why does Kaldi choose to do this?

In addition, what is latbin/lattice-align-words.cc doing exactly?
After aligning, I see plenty of silence phones appear in the lattice,
and the weights seem to be pushed. I assume the weights after aligning
are not meaningful for individual edges anymore and are only
meaningful for the whole path?

Thanks,
Hao
