 # We recommend you run this script stage by stage.
 
+# This recipe includes:
+# 1. downloading a pretrained model on the simulated data from switchboard and NIST,
+# 2. finetuning the pretrained model on Callhome1.
+# Finally, you will get a slightly better DER result 9.95% on Callhome2 than that in the paper 10.14%.
