- * HISTORY
- *
- *
- * 22-Nov-2004 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University
- * Imported from s3.2, for supporting s3 format continuous
- * acoustic models.
- *
- * 14-Oct-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
- * Added mdef_sseq2sen_active().
- *
- * 06-May-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
- * In mdef_phone_id(), added backing off to silence phone context from filler
- * context if original triphone not found.
- *
- * 30-Apr-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon
- * Added senone-sequence id (ssid) to phone_t and appropriate functions to
- * maintain it. Instead, moved state sequence info to mdef_t.
- *
- * 13-Jul-96 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * Added mdef_phone_str().
- *
- * 01-Jan-96 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * Allowed mdef_phone_id_nearest to return base phone id if either
- * left or right context (or both) is undefined.
- *
- * 01-Jan-96 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * Created.

-
-
-/*
- * Major assumptions:
- * All phones have same #states, same topology.
- * Every phone has exactly one non-emitting, final state--the last one.
- * CI phones must appear first in model definition file.
