This directory (sitw) contains example scripts for the Speakers in the
   Wild (SITW) Speaker Recognition Challenge.  The SITW corpus is required,
   and can be obtained by following the directions at the url
   http://www.speech.sri.com/projects/sitw/
  
   Additional data sources (e.g., VoxCeleb and MUSAN) are required to train
   the systems in the subdirectories.  See the corresponding README.txt files
   in the subdirectories for more details. 
  
   Note: This recipe requires ffmpeg to be installed and its location included
   in $PATH.
  
   The subdirectories "v1" and so on are different speaker recognition
   recipes. The recipe in v1 is a traditional i-vector system while the v2
   recipe uses DNN embeddings called x-vectors.
