| * 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. | |
