 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 in local/nnet3/xvector/tuning/run_xvector_1a.sh is
 closesly based on the following paper:

 @inproceedings{snyder2018xvector,
 title={X-vectors: Robust DNN Embeddings for Speaker Recognition},
 author={Snyder, D. and Garcia-Romero, D. and Sell, G. and Povey, D. and Khudanpur, S.},
 booktitle={2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)},
 year={2018},
 organization={IEEE},

 }

 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).
