DBHN-Net: Dual-Branch Hybrid Neural Network For Low-Complexity Monaural Speech Enhancement
Researchers have developed a new Dual-Branch Hybrid Neural Network (DBHN-Net) designed to significantly reduce the computational complexity and power consumption of speech enhancement systems. The network integrates traditional Artificial Neural Networks (ANNs) with Spiking Neural Networks (SNNs), where the SNN branch handles power reduction and the ANN branch compensates for potential information loss. This hybrid approach, along with specialized modules for feature extraction and fusion, reportedly achieves superior performance on public datasets while reducing computational complexity by an average of 7.5 times compared to existing models.
