Partially Adaptive Multichannel Joint Reduction of Ego-noise and Environmental Noise

no code implementations27 Mar 2023 Huajian Fang, Niklas Wittmer, Johannes Twiefel, Stefan Wermter, Timo Gerkmann

In this paper, we propose a multichannel partially adaptive scheme to jointly model ego-noise and environmental noise utilizing the VAE-NMF framework, where we take advantage of spatially and spectrally structured characteristics of ego-noise by pre-training the ego-noise model, while retaining the ability to adapt to unknown environmental noise.

Uncertainty Estimation in Deep Speech Enhancement Using Complex Gaussian Mixture Models

no code implementations9 Dec 2022 Huajian Fang, Timo Gerkmann

Single-channel deep speech enhancement approaches often estimate a single multiplicative mask to extract clean speech without a measure of its accuracy.

Integrating Statistical Uncertainty into Neural Network-Based Speech Enhancement

no code implementations4 Mar 2022 Huajian Fang, Tal Peer, Stefan Wermter, Timo Gerkmann

Speech enhancement in the time-frequency domain is often performed by estimating a multiplicative mask to extract clean speech.

Variational Autoencoder for Speech Enhancement with a Noise-Aware Encoder

no code implementations17 Feb 2021 Huajian Fang, Guillaume Carbajal, Stefan Wermter, Timo Gerkmann

Recently, a generative variational autoencoder (VAE) has been proposed for speech enhancement to model speech statistics.
