Likelihood of different pronunciations

[Vladislav Shakhray]

Hi,

I have a lexicon where some words have multiple pronunciations. When I ran force alignment, Kaldi (gmm-align-compiled) will choose the best pronunciation given the utterance. How can I find the likelihood for each of the pronunciation variants? 

Many thanks, 

Vlad

I guess you could look at two scripts we have:

steps/get_prons.sh

utils/dict_dir_add_pronprobs.sh

(grep egs to see how they are used)

The output lexiconp.txt should contain the probabilities

I'm not aware of how to do this on per utterance easily

Thanks for your answer Yenda!

Yes, I saw that I could get probabilities for each pronunciation in general using steps/get_prons.sh.

I would like to find the probability of each pronunciation for the given utterance. 

gmm-align-compiled.cc script somehow picks the right pronunciation (in most cases) and as I understood it considers different pronunciations per word and picks the one which gives higher log-likelihood. So it seems that information I need should be somewhere but I can’t figure out how to access it.

I don't actually know if there is something useful for that.

I wonder if the gop scripts might be useful or do something along those lines?

align_lats.sh produces lattices with alternative prons in them; lattice-to-arc-post or scripts that use that, should be able to give you prons, but a lattice-align-words pass may be needed first.
