[Kaldi-developers] methods for phoneme recognitions

[Nathan D. <nd...@ca...>]

I'm trying to put to create a tool to recognize spoken phonemes for children's reading comprehension, i.e., children speaking phonemes only, not the words and of course not a sentence.

After looking a bit more, it looks there are a couple of good options:

1 - (thanks Dan) Create a lexicon consisting of just phones, that you can use at test time - removing the word-position-dependencey 
2 - Extract phones directly from transitions prior to word alignment (i.e., directly from the acoustic model).   

For #2 - I would worry that the lack of information might be problematic.  The advantage is that I only need enough data for the acoustic model.   Anyway, I would be very happy to share whatever I do come up with with.  

Any thoughts on this would be helpful.

Thanks,
