force alignment #92

Closed xfwu closed 8 years ago

xfwu commented 8 years ago

What is the best way to do a force alignment/decoding in Eesen? I want to generate the alignment of the reference, given the softmaxed output

I just checked in new updates to do so. The high-level script is align_ctc_single_utt.sh Note that currently we can only generate alignments utterance by utterance, rather than in a batch mode (as in Kaldi)

Thank you very much!

I presume that the uttdata-dir stores only one utterance's reference, therefore the G.fst generated out of this reference will be used to generate only a very compact lattice, and the the 1best path found in that lattice is actually the reference!!

this is very cool!

Yep, your understanding is correct.
