The PCG-AIID System for L3DAS22 Challenge: MIMO and MISO convolutional recurrent Network for Multi Channel Speech Enhancement and Speech Recognition [article]

Jingdong Li, Yuanyuan Zhu, Dawei Luo, Yun Liu, Guohui Cui, Zhaoxia Li
This paper described the PCG-AIID system for L3DAS22 challenge in Task 1: 3D speech enhancement in office reverberant environment.  ...  In the second stage, a multiple input and single output (MISO) network is applied to enhance the speech from desired direction and post-filtering.  ...  Convolutional Recurrent Network As illustrated in Figure . 1, we use convolutional recurrent network (CRN) [13] as the basic structure to estimate single channel and multi-channel complex spectrogram  ...
