# This recipe aims at reimplement the results of SOND on Callhome corpus which is represented in
# [1] TOLD: A Novel Two-stage Overlap-aware Framework for Speaker Diarization, ICASSP 2023
# You can also use it on other dataset such AliMeeting to reproduce the results in
# [2] Speaker Overlap-aware Neural Diarization for Multi-party Meeting Analysis, EMNLP 2022
# We recommend you run this script stage by stage.

# This recipe includes:
# 1. simulating data with switchboard and NIST.
# 2. training the model from scratch for 3 stages:
#   2-1. pre-train on simu_swbd_sre
#   2-2. train on simu_swbd_sre
#   2-3. finetune on callhome1
# 3. evaluating model with the results from the first stage EEND-OLA,
# Finally, you will get a similar DER result claimed in the paper.
