This section describes the x-vector system. It is based on the DNN
embeddings in  and described in greater detail there.
Our software framework has been made available in the Kaldi
toolkit. An example recipe is in the main branch of Kaldi at https:
sre16/v2 and a pretrained x-vector system can be downloaded
from http://kaldi-asr.org/models.html. The recipe
and model are similar to the x-vector system described in Section
