+ This recipe replaces iVectors used in the v1 recipe with embeddings extracted
+ from a deep neural network.  In the scripts, we refer to these embeddings as
+ "xvectors."  The recipe is based on 
+ http://www.danielpovey.com/files/2017_interspeech_embeddings.pdf but with
+ improvements due to augmentation in the DNN training data.
+
+ The recipe uses the following data for system development.  This is in
+ addition to the NIST SRE 2016 dataset used for evaluation (see ../README.txt).
