Hello all, i very new at pocketsphinx, and i would need to find the function
that returns the log-likelood of each utterance becouse i need that value to
continue (i am working on speaker verification). If anyone can lead me to the
function or even a brief description of the way Pocketsphinx applies viterbi
algorithm i would really appreciate it. Thanks a lot!

Oh, thanks a lot. I am more used to dealing with HTK so i thought there would
also be in sphinx a function that directly outputs the score. Thanks!!

Sorry, i have been looking for ps_alignment in the doxygen and i couldn't find
it. Also would you know what steps should i take to obtain the likelihoods of
each phoneme in an utterance, and also the likelihood of the entire utterance?
becouse i can't see it clearly. Thanks a lot

There is no such function. You can construct score from ps_alignment results
if you need it.
