* 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 14:48:13 arthchan2003
* Merged from SPHINX3_5_2_RCI_IRII_BRANCH: Added adapt_set_mllr (Moved from kb)
*
*
* Revision 1.1.4.3 2005/09/18 01:12:31 arthchan2003
* Add adapt_set_mllr which is responsible for single stream MLLR switching.
*
* Revision 1.1.4.2 2005/07/05 05:47:59 arthchan2003
* Fixed dox-doc. struct level of documentation are included.
*
* Revision 1.1.4.1 2005/06/27 05:22:19 arthchan2003
* Merged from the HEAD.
*
* Revision 1.2 2005/06/22 08:00:07 arthchan2003
* Completed all doxygen documentation on file description for libs3decoder/libutil/libs3audio and programs.
* Revision 1.2 2005/06/22 08:00:07 arthchan2003
* Completed all doxygen documentation on file description for libs3decoder/libutil/libs3audio and programs.
*
* Revision 1.1 2005/06/21 17:59:44 arthchan2003
* Log: Implementation and Interface of adapt_am_t, a wrapper of
* adaptation capabability of Sphinx 3. It takes the responsibility from
* kb_t to manage regA, regB and mllr_nclass. Interfaces are not fully
* completed. So "pointer" symtom code still appears in kb.c
*
* Revision 1.3 2005/06/19 19:41:21 archan
* Sphinx3 to s3.generic: Added multiple regression class for single stream MLLR. Enabled MLLR for livepretend and decode.
*
* Revision 1.2 2005/03/30 01:08:37 archan
* codebase-wide update. Performed an age-old trick: Adding $Log into all .c and .h files. This will make sure the commit message be preprended into a file.
*
*
* 25-Mar-2005 Arthur Chan (archan@cs.cmu.edu) at Carnegie Mellon Unversity
* First started.
