* HISTORY
* $Log$
* Revision 1.1 2006/04/05 20:27:30 dhdfu
* A Great Reorganzation of header files and executables
*
* Revision 1.3 2006/02/22 16:57:15 arthchan2003
* Fixed minor dox-doc issue
*
* Revision 1.2 2006/02/22 16:56:01 arthchan2003
* Merged from SPHINX3_5_2_RCI_IRII_BRANCH: Added ms_mgau.[ch] into the trunk. It is a wrapper of ms_gauden and ms_senone
*
* Revision 1.1.2.4 2005/09/25 18:55:19 arthchan2003
* Added a flag to turn on and off precomputation.
*
* Revision 1.1.2.3 2005/08/03 18:53:44 dhdfu
* Add memory deallocation functions. Also move all the initialization
* of ms_mgau_model_t into ms_mgau_init (duh!), which entails removing it
* from decode_anytopo and friends.
*
* Revision 1.1.2.2 2005/08/02 21:05:38 arthchan2003
* 1, Added dist and mgau_active as intermediate variable for computation. 2, Added ms_cont_mgau_frame_eval, which is a multi stream version of GMM computation mainly s3.0 family of tools. 3, Fixed dox-doc.
*
* Revision 1.1.2.1 2005/07/20 19:37:09 arthchan2003
* Added a multi-stream cont_mgau (ms_mgau) which is a wrapper of both gauden and senone. Add ms_mgau_init and model_set_mllr. This allow eliminating 600 lines of code in decode_anytopo/align/allphone.

/** \file ms_mgau.h
*
* \brief (Sphinx 3.0 specific) A module that wraps up the code of
* gauden and senone because they are closely related.
*
* At the time at Sphinx 3.1 to 3.2, Ravi has decided to rewrite only
* single-stream part of the code into cont_mgau.[ch]. This marks the
* beginning of historical problem of having two sets of Gaussian
* distribution computation routine, one for single-stream and one of
* multi-stream.
*
* In Sphinx 3.5, when we figure out that it is possible to allow both
* 3.0 family of tools and 3.x family of tools to coexist. This
* becomes one problem we found that very hard to reconcile. That is
* why we currently allow two versions of the code in the code
* base. This is likely to change in the future.
