Haoran Zhao, Nan Li, Runqiang Han, Xiguang Zheng, Chen Zhang, Liang Hui Guo, Bing Yu · 2023
This paper describes our submission to the fourth Acoustic Echo Cancellation (AEC) Challenge, which is part of ICASSP 2023 Signal Processing Grand Challenge. The proposed system is developed based on our earlier system submitted to the ICASSP 2022 AEC challenge with significant latency and network structure improvement, while achieving better subjective results.
