3D Audio Signal Processing Systems for Speech Enhancement and Sound Localization and Detection

The L3DAS23 of ICASSP Signal Processing Grand Challenge encourages research on 3D audio signal processing, such as 3D speech enhancement (SE) and 3D sound localization and detection (SELD). In this paper, we propose a two-stage system based on DPRNN and UNet for the SE task and a Conformer-based system for the SELD task. The proposed SE and SELD systems are evaluated on the L3DAS23 blind test sets. Results show that the proposed methods achieve state-of-the-art performance for 3D SE and SELD.
