Log likelihood score of the aligned segment to be a particular phone #11

Open tang-kevin opened 1 year ago

Dear MFA dev,

I was wondering if it is possible to obtain probability scores from the alignment output. I mean, the log probability (log probability density) of the aligned segment to be a particular phone. I would like to use the method proposed by Yuan, J., & Liberman, M. (2009). Investigating /l/ variation in English through forced alignment. In Tenth Annual Conference of the International Speech Communication Association.

I looked around and it seems that this is possible in Kaldi (https://sourceforge.net/p/kaldi/discussion/1355348/thread/3a866d2a/). Apparently Penn Phonetics Lab Forced Aligner can also do it.

Many thanks, Kevin
