Multiple pronunciations and Automated Audio Segmentation Using Forced Alignment

I was trying out the forced alignment using HTK as described in the "Automated Audio Segmentation Using Forced Alignment" document.   Everything worked great, except that I noticed that the VoxForge dictionary has multiple pronunciations for many words using a (2) suffix on the word.   When running this process, the dictionary created for doing the forced alignment uses only the first pronunciations.   Is that intended, or is there a mismatch here in the lexicon format that HTK expects?

PS: Thanks for that great tutorial!

HTK's "forced alignment" matches the phoneme sounds it hears to the words in the pronunciation dictionary (kind of  like a 'reverse lookup'...).  Therefore, it seems that your pronunciations best match the first instance of the words with multiple pronunciations.

You might also be interested in an Perl audio segmentation script that I started on a while ago: Audiobook.pm.  The documentation is inline Perldoc.

I did not add it to the Automated Audio Segmentation Using Forced Alignment page because it still needs some refinements... but I have successfully used it to segment speech text.
