Re: [Kaldi-users] Problem with align-mapped

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

I just committed a change to compile-train-graphs so that it notices
when graphs are empty and does not output them, and prints warnings.
The underlying problem here is probably something like a lexicon
mismatch or a lexicon that lacks some pronunciations.
