* lts.h -- Letter to sound rule support
*
* $Log$
* Revision 1.1 2006/04/05 20:27:30 dhdfu
* A Great Reorganzation of header files and executables
*
* Revision 1.2 2006/02/22 20:44:17 arthchan2003
* Merged from branch SPHINX3_5_2_RCI_IRII_BRANCH: As we have done in SphinxTrain and with the permission of flite developer. check in the routines for using LTS. In dict.c, one will see detail comment on how it was used and how we avoid problematic conditions.
*
* Revision 1.1.2.1 2005/09/25 19:07:52 arthchan2003
* Added LTS rules and the module to use it.
