  This paper describes the XMUSPEECH speaker recognition and diarisation
systems for the VoxCeleb Speaker Recognition Challenge 2021. For track 2, we
evaluate two systems including ResNet34-SE and ECAPA-TDNN. For track 4, an
important part of our system is VAD module which greatly improves the
performance. Our best submission on the track 4 obtained on the evaluation set
DER 5.54% and JER 27.11%, while the performance on the development set is DER
2.92% and JER 20.84%.
