SE Territory: Monaural Speech Enhancement Meets the Fixed Virtual Perceptual Space Mapping

no code implementations3 Nov 2023 Xinmeng Xu, Yuhong Yang, Weiping tu

To overcome this limitation, we introduce a strategy to map monaural speech into a fixed simulation space for better differentiation between target speech and noise.

Exploring the Interactions between Target Positive and Negative Information for Acoustic Echo Cancellation

no code implementations26 Jul 2023 Chang Han, Xinmeng Xu, Weiping tu, Yuhong Yang, Yajie Liu

We observe that besides target positive information, e. g., ground-truth speech and features, the target negative information, such as interference signals and features, helps make pattern of target speech and interference signals more discriminative.

All Information is Necessary: Integrating Speech Positive and Negative Information by Contrastive Learning for Speech Enhancement

no code implementations26 Apr 2023 Xinmeng Xu, Weiping tu, Chang Han, Yuhong Yang

In this study, we propose a SE model that integrates both speech positive and negative information for improving SE performance by adopting contrastive learning, in which two innovations have consisted.

Injecting Spatial Information for Monaural Speech Enhancement via Knowledge Distillation

no code implementations2 Dec 2022 Xinmeng Xu, Weiping tu, Yuhong Yang

To address this issue, we inject spatial information into the monaural SE model and propose a knowledge distillation strategy to enable the monaural SE model to learn binaural speech features from the binaural SE model, which makes monaural SE model possible to reconstruct higher intelligibility and quality enhanced speeches under low signal-to-noise ratio (SNR) conditions.
