Self-supervised Pretraining for Robust Personalized Voice Activity Detection in Adverse Conditions

no code implementations27 Dec 2023 Holger Severin Bovbjerg, Jesper Jensen, Jan Østergaard, Zheng-Hua Tan

Our experiments show that self-supervised pretraining not only improves performance in clean conditions, but also yields models which are more robust to adverse conditions compared to purely supervised learning.
