Learning Robust Spatial Representations from Binaural Audio through Feature Distillation
Holger Severin Bovbjerg, Jan Østergaard, Jesper Jensen +2
Recently, deep representation learning has shown strong performance in multiple audio tasks. However, its use for learning spatial representations from multichannel audio is undere…
Self-supervised Pretraining for Robust Personalized Voice Activity Detection in Adverse Conditions
Holger Severin Bovbjerg, Jesper Jensen, Jan Østergaard +1
In this paper, we propose the use of self-supervised pretraining on a large unlabelled data set to improve the performance of a personalized voice activity detection (VAD) model in…
Improving Label-Deficient Keyword Spotting Through Self-Supervised Pretraining
Holger Severin Bovbjerg, Zheng-Hua Tan
Keyword Spotting (KWS) models are becoming increasingly integrated into various systems, e.g. voice assistants. To achieve satisfactory performance, these models typically rely on…
