For every ci-phone, every word end, a tree will be allocated to preserve its pathscore. This is different from 3.5 or below, only the best score for a particular ci-phone, regardless of the word-ends will be preserved at every frame. The graph propagation will not collect unused word tree at this point. srch_WST_propagate_wd_lv2 is also as the most stupid in the century. But well, after all, everything needs a start. I will then really get the results from the search and see how it looks. + * + * Revision 1.4 2005/04/21 23:50:26 archan + * Some more refactoring on the how reporting of structures inside kbcore_t is done, it is now 50% nice. Also added class-based LM test case into test-decode.sh.in. At this moment, everything in search mode 5 is already done. It is time to test the idea whether the search can really be used. + * + * Revision 1.3 2005/03/30 01:22:47 archan + * Fixed mistakes in last updates.
