hi all,

im going to develop a speech recognition system using my native language for dialing a number and i need the recognized sinhala speech as an english text output like below.

  call 0 1 1 3 4 5 6 3 2 6

my native language is sinhala and for an example ,

call = "amathanna"

1 = "eka"

2 = "deka" etc

so my speech will be "amathanna eka deka thuna... " like that.

so can you please tell me how im going to start this project using htk + julian??

Is it possible to do by using julian?

And also tel me how to write the task grammer for my problem.. Thanx a lot.

First, get a better understanding of how to do this in English using the VoxForge Tutorial.

Then create a pronunciation dictionary for sinhala and record some speech (using words from your pronunciation dictaionary), and then create a monophone acoustic model (up to step 8 in the VoxForge Tutorial).

For better recognition results, you can thereafter create a triphone acoustic model, but this requires a sinhala "question" file.  

The problem with HTK/Julius is thht you need to create the "question" file yourself.  Whereas the CMU Sphinx acoustic model trainer: Sphinxtrain can create one for you.  Manually created "question" file are usually better, but you may need some linguistic training to create one yourself.
