Re: [Kaldi-users] Convert kaldi lattices into HTK compatible format, utils/convert_slf.pl

Hi David,

yes, the numbers associated with the words are indices, you can
resolve them using the data/lang/words.txt file. The warnings you see
relate to process of alignining the lattices to words (i.e. making
sure that the word arcs (transitions) reflect the actual word
boundaries in terms of time), and not to the SLF conversion. To get
rid of the epsilon transitions you may need to determinize the
lattices first (please correct me, if I'm wrong, Dan).
