Hi,

I found your Dutch acoustic model on this site and wondered if it can be used also in the java environment of Sphinx 4. I tried to convert the Dutch acoustic model to Sphinx 4 following the steps described here http://cmusphinx.sourceforge.net/sphinx4/doc/UsingSphinxTrainModels.html

I'm not sure this works. Has anyone ever tried to use the acoustic model in Sphinx 4 or is it only usable in Sphinx 3?

Hi Quioz 

>I'm not sure this works. Has anyone ever tried to use the acoustic model in Sphinx 4 or is it only usable in Sphinx 3?

I have not tried it.  nsh would be the best person to answer your question - he created the acoustic models you are asking about. 

Regardless, this page on the Sphinx4 site seems to indicate that you should be able to do it:

Currently, Sphinx-4 uses models created with SphinxTrain, also available at cmusphinx.org. SphinxTrain generates acoustic models in the format used by Sphinx-3. To create a package as used by Sphinx-4, please check the page about using SphinxTrain models.

Hm, I missed this one, sorry. It should work with a proper config. Just ask if you have problems

Can anyone please tell me how i can use Sphinx4 for free speech recognition in the case of large vocabulary? I have been succesfuly runing the demos, but they are just demos. and limited to digits or specific sentences. which file in the Sphinx4 package i will have to run in order to do speech recognition where the user is allowed to say anything.

your help will be highly appreciated,

Regards

Please take a look at Evaldictator project:

Also you need to read Programmers Manual and configuration files in sphinx4/performance/hub4. I hope that helps.
