Neural Spatio-Temporal Beamformer for Target Speech Separation

1 code implementation8 May 2020 Yong Xu, Meng Yu, Shi-Xiong Zhang, Lian-Wu Chen, Chao Weng, Jianming Liu, Dong Yu

Purely neural network (NN) based speech separation and enhancement methods, although can achieve good objective scores, inevitably cause nonlinear speech distortions that are harmful for the automatic speech recognition (ASR).

Enhancing End-to-End Multi-channel Speech Separation via Spatial Feature Learning

no code implementations9 Mar 2020 Rongzhi Gu, Shi-Xiong Zhang, Lian-Wu Chen, Yong Xu, Meng Yu, Dan Su, Yuexian Zou, Dong Yu

Hand-crafted spatial features (e. g., inter-channel phase difference, IPD) play a fundamental role in recent deep learning based multi-channel speech separation (MCSS) methods.
