DBHN-Net: Dual-Branch Hybrid Neural Network For Low-Complexity Monaural Speech Enhancement

arXiv:2606.05911v1 Announce Type: cross Abstract: Although artificial neural network (ANN) based speech enhancement (SE) methods demonstrate excellent performance, the high computational complexity and high energy consumption hinder their deployment in practical front-end processing tasks.} Currently, the spiking neural networks (SNNs) have shown potential in reducing power consumption. However, the discrete binary activation and complex spatio-temporal dynamics of SNNs often result in information loss. The current challenge therefore focuses on how to maintain performance and reduce computati

Why this matters
Why now

The increasing deployment of AI in edge devices and the pervasive use of speech enhancement necessitate more efficient, lower-power computational models for real-world application.

Why it’s important

Reducing computational complexity and energy consumption in AI models is critical for broadening their applicability, especially in portable and resource-constrained environments.
