Data required for system development (on top of the data for testing described
   in ../README.txt), consists of Fisher, past NIST SREs, and Switchboard
   cellular.  You can probably get by OK with just one part of Fisher.
    
                        Speech       Transcripts (see note)
     Fisher part 1     LDC2004S13        LDC2004T19
     Fisher part 2     LDC2005S13        LDC2005T19
     SRE 2004 Test     LDC2006S44
     SRE 2005 Test     LDC2011S04
     SWBD Cellular 1   LDC2001S13
     SWBD Cellular 2   LDC2004S07
  
  
  Note:
   The distributions with the transcripts are not really needed for the
   transcripts themselves, but because that's where the speaker information
   resides (so we know which recordings are from the same speaker).  This is
   needed for PLDA estimation.  However, bear in mind that Fisher is not believed
   to be very good for things like PLDA estimation. In newer recipes such as
   ../../sre10/v1 we use past SRE data for PLDA estimation.
