Tuning CMU Sphinx

Question

I am trying to build a speech recognition app based on CMU Sphinx. I have created my own language model using the lmtool. But inorder to improve the accuracy of recognition, I want to tune Sphinx. But are there any guidelines for choosing the properties like absoluteBeamWidth, relativeBeamWidth, absoulteWordBeamWidth, languageWeight. I am not exactly sure what these properties mean. Also any links to the resource(excluding the incomplete tuning link on the sphinx website) that can help me in tuning Sphinx will be appreciated.

Thank you

But inorder to improve the accuracy of recognition, I want to tune Sphinx.

Accuracy is not improved through tuning but by using better models and more advanced algorithms. See the FAQ for details:
