Wind Noise Reduction with a Diffusion-based Stochastic Regeneration Model

1 code implementation22 Jun 2023 Jean-Marie Lemercier, Joachim Thiemann, Raphael Koning, Timo Gerkmann

We show that our stochastic regeneration model outperforms other neural-network-based wind noise reduction methods as well as purely predictive and generative models, on a dataset using simulated and real-recorded wind noise.

A neural network-supported two-stage algorithm for lightweight dereverberation on hearing devices

no code implementations6 Apr 2022 Jean-Marie Lemercier, Joachim Thiemann, Raphael Koning, Timo Gerkmann

By deriving new metrics analyzing the dereverberation performance in various time ranges, we confirm that directly optimizing for a criterion at the output of the multi-channel linear filtering stage results in a more efficient dereverberation as compared to placing the criterion at the output of the DNN to optimize the PSD estimation.

Neural Network-augmented Kalman Filtering for Robust Online Speech Dereverberation in Noisy Reverberant Environments

no code implementations6 Apr 2022 Jean-Marie Lemercier, Joachim Thiemann, Raphael Koning, Timo Gerkmann

In this paper, a neural network-augmented algorithm for noise-robust online dereverberation with a Kalman filtering variant of the weighted prediction error (WPE) method is proposed.
