VERSION DATE INSTALLED AT NOTES
CTK v.1.1.1 7/3/01 /share/spandh.25/CTK Many minor bugs fixed. A few minor improvements to GUI.

Notes

!!! This release includes a fix to a bug in the likelihood calculation in the HMMDecoder blocks. This is a fairly serious bug and the new code will produce slightly different recognition results. Fortunately, tests on the Aurora 2.0 test set A with soft missing data masks, have shown that the impact on the results is minor. Results on clean seem to be largely unaffected, and no result has changed by more than 1%. !!!

The change to the code is at line 786 of ctk_HMM_decoder.cpp.
