The following index files are located in this directory, 
CD2-4.2: /rm1/doc/train.  They indicate standard training sets for previous
DARPA benchmark tests and should be used when replicating these tests.
The test material can be found in CD2-4.2: /rm1/doc/tests.

25_indtr.ndx: augmented speaker-independent system training files used in 
              Sphinx test; when added to files in 80_indtr.ndx, creates Sphinx 
              105-speaker training set

37_indtr.ndx: augmented speaker-independent system training files; when added 
              to standard 72-speaker training set in file 72_indtr.ndx, forms 
              109-speaker augmented training set

6a_deptr.ndx: first half of speaker-dependent system training files; when 
              added to file 6b_deptr.ndx, forms the standard 12-speaker 
              training set

6b_deptr.ndx: second half of speaker-dependent system training files; when 
              added to file 6a_deptr.ndx, forms the standard 12-speaker 
              training set

72_indtr.ndx: standard speaker-independent training set files;

80_indtr.ndx: speaker-independent system training files used in Sphinx test; 
              when added to files in 25_indtr.ndx, creates Sphinx 105-speaker
              training set
