End‐to‐end speech‐denoising deep neural network based on residual‐attention gated linear units

Electronics Letters, Volume 60, Issue 20, October 2024.
The current gated linear unit (GLU) utilizes half of the signal as a gating signal, applying it to the main signal portion corresponding to the speech feature map of the other half. In contrast, the proposed residual‐attention GLU employs a residual‐attention network to improve the channel and temporal context within the signal, enhancing the noise ...

Rethinking multi‐spatial information for transferable adversarial attacks on speaker recognition systems

CAAI Transactions on Intelligence Technology, Volume 9, Issue 3, Page 620-631, June 2024.
Abstract Adversarial attacks have been posing significant security concerns to intelligent systems, such as speaker recognition systems (SRSs). Most attacks assume the neural networks in the systems are known beforehand, while black‐box attacks are proposed without such information to meet practical situations.

Impact of Background Traffic on Speech Quality in VoWLAN

Advances in Multimedia, 2007
This paper describes measurements of the impact of background traffic on speech quality in an environment of WLANs (IEEE 802.11). The simulated background traffic consists of three types of current traffics in telecommunication networks such as data ...

Single-Channel Speech Enhancement Based on Adaptive Low-Rank Matrix Decomposition

IEEE Access, 2020
The low-rank matrix decomposition (LMD) algorithm based on the maximum correntropy criterion (MCC) has recently shown its superiority to other algorithms in classification (e.g., face recognition), and we develop it into single-channel speech enhancement
