> If i want to update the voxforge dictionary...how i can do that?

If you only have a few words, you can update it manually.  Just look at how other similar words are pronounced and write out the phonemes.  If you have many words, then you might need to look at a G2P solution.

It gets trickier is you did not record any acoustic data for the triphones that are contained in the words you add.  You can either record speech for those words and retrain your acoustic model, or update your tiedlist file to map the new triphones to other similar triphones (or biphones) that are actually in your acoustic model.

Hi Ken,

I tried the g2p solution as suggested by you, i tried with Sequitur g2p and i am able to get the phonmes  for required words. but the problem i am facing is, how to update the tied list which is used in julius.

For ex: if i have word and respective phoneme like

gururaj        g uw r uw r ay

i want to add this in tied list how to do that ?

Hi ken

I got resolved that issue, word is out of order. But now i am facing another issue,

When i try to run the following command, as per the tutorial,

HHEd -A -D -T 1 -H hmm12/macros -H hmm12/hmmdefs -M hmm13 tree.hed triphones1

i get this error,

AU ./fulllist
 Creating HMMset using trees to add unseen triphones
  ERROR [+2662]  FindProtoModel: no proto for d-jh+aa in hSet
 FATAL ERROR - Terminating program HHEd

What is the possible solution for this ? thank you

>ERROR [+2662]  FindProtoModel: no proto for d-jh+aa in hSet

you need to record audio with 3-5 words containing the triphone:  d-jh+aa

search for "ERROR [+2662]  FindProtoModel: no proto" on the VoxForge website to get more info.

Hi ken

Is there any solution where i can update the voxforge dictionary used in julius by adding the new words and triphones which i get from g2p solution to the dictionary and get the tied list by running the step 10 of the tutorial.

I dont want to record words, just need to update the dictionary. i am finding it difficult. if u guide me it will be helpful.

Thank you
