Re: [Kaldi-developers] Times in Kaldi Lattices

[Daniel P. <dp...@gm...>]

It's a shame that you're using the older versions of the script.  Currently
the "s5" scripts are the canonical ones.  Your issue with times greater
than the length of the file is very unexpected.  This is not the kind of
error I would expect to ever arise.
RE getting the N-best or 1-best sequences-- the programs lattice-nbest and
lattice-1best are relevant here; they output stuff in the regular lattice
format, and you can then put them through lattice-word-align (old scripts)
or lattice-align-words (new scripts), and convert the output to, say, ctm
format-- you can check the scripts for how to convert to ctm format, it's
something like lattice-to-ctm, but there are scripts such as get_ctm.sh and
get_train_ctm.sh in s5.
