rks_mfs  asks:

Hi,

I am trying to get Sphinx to work with Indian languages and thinking of working with phone set for one language at a time.

What is the best approach to do this in Sphinx. Can I directly work with phoneme decoder so that I do not have to get into Vocabulary and word dictionary.

Does Sphinx do phoneme only output and is the recognition real time.

for instance if I say "Hello" how can i get a phoneme which recognize 'h' first then 'e' then 'l' then 'l' then 'o' each independently?


Thanks.

Hi rks_mfs,

>I am trying to get Sphinx to work with Indian sub-languages and thinking of

>working with phone set for one language at a time.

Do you mean you want Sphinx to recognize speech from more than one Indian language at the same time? Why? what is the application you are thinking of?

>thinking of working with phone set for one language at a time.

Do you mean that you want to have a separate phone set for each Indian sub-language?  

>for instance if I say "Hello" how can i get a phoneme which recognize 'h'

>first then 'e' then 'l' then 'l' then 'o' each independently?

Why would you want to do this?  What are you trying to do? 

Strictly speaking, speech recognition works with phones rather than phonemes, so that it only distinguishes between distinct units of sound.  If in your target language, a letter matches directly to a sound, then you should be able to use speech recognition to distinguish the letters.  This is *not* the case in English.

Hope that helps, 

Ken

Hello Ken,
We are very thankfull for your  guidence.
I am working with an Indian language "Hindi" in which a letter matches directly with a sound.
For this , we will have to create an acoustic model and dictonary in which mapping between alphabet and phoneme is defined.
For grapheme-based acoustic modeling, where can I find the steps necessary to build the dictionary by treating each character as a phone. What are the requirements to follow this track.
With Regards

Use Google. 

This first article speaks directly to your question:

These articles talk about using English acoustic models to bootstrap phone models for a new language:

Hello Ken,
We are very thankfull for your  guidence.
I want to test the sphinx-3 decoder in windows using a wave file. But I do not have any application which could perform this task.
Since I am new user of sphinx so I do not have much idea about sphinx-3.
So can you please guide me what are the steps we will have to follow to do this work.
Thanks
