  Many speaker recognition challenges have been held to assess the speaker
verification system in the wild and probe the performance limit. Voxceleb
Speaker Recognition Challenge (VoxSRC), based on the voxceleb, is the most
popular. Besides, another challenge called CN-Celeb Speaker Recognition
Challenge (CNSRC) is also held this year, which is based on the Chinese
celebrity multi-genre dataset CN-Celeb. This year, our team participated in
both speaker verification closed tracks in CNSRC 2022 and VoxSRC 2022, and
achieved the 1st place and 3rd place respectively. In most system reports, the
authors usually only provide a description of their systems but lack an
effective analysis of their methods. In this paper, we will outline how to
build a strong speaker verification challenge system and give a detailed
analysis of each method compared with some other popular technical means.
