how to build continuous model?

[Anonymous]

hello,
I would like to build continuous model using SphinxTrain. I came to know that the default settings in the etc/sphinx_train.cfg  file are used for building semi-continuous model. What are the necessary modifications required to be done in the configuration file. I am in extreme need of it.
If anyone knows ...kindly reply.
                  Thank you,

I've never trained a continuous model using the SphinxTrain scripts, so I hope that someone who has done so will reply.  From the comments in the file etc/sphinx_train.cfg, I can tell you:

1. The variable $CFG_HMM_TYPE should be changed from '.semi.' to '.cont.' .

2. In addition, for Sphinx3, you may want to change the variables $CFG_FEATURE and $CFG_NUM_STREAMS for a different set of features and number of feature streams.

But I don't know if there are other settings that should be made...

hi Jerry...
Thanx for your reply. As you said I changed the following in etc/sphinx_train.cfg, but could not work:

(1).        $CFG_FEATURE = "c/1..L-1/,d/1..L-1/,c/0/d/0/dd/0/,dd/1..L-1/"; to $CFG_FEATURE = "1s_12c_12d_3p_12dd";

(2).        $CFG_NUM_STREAMS = 4;  to  $CFG_NUM_STREAMS = 1;

(3).        $CFG_TYPE = '.semi.'  to $CFG_TYPE = '.cont.';

The steps 00 and 01 in tinydoc.txt run correctly but giving fatal_error at step 02(i.e., training context independent model).

I don't know whether the modifications that I have done in etc/sphinx_train.cfg are wrong, or I need to do some more modifications.

Please...those who have done this can reply.

ThanQ

One more thing Jerry....
Have you used sphinx-III decoder for your semi-continuous model?????
