Nonlinear Residual Echo Suppression Based on Multi-stream Conv-TasNet
Hongsheng Chen, Teng Xiang, Kai Chen +1
Acoustic echo cannot be entirely removed by linear adaptive filters due to the nonlinear relationship between the echo and far-end signal. Usually a post processing module is requi…
Target Speech Extraction Based on Blind Source Separation and X-vector-based Speaker Selection Trained with Data Augmentation
Zhaoyi Gu, Lele Liao, Kai Chen +1
Extracting the desired speech from a mixture is a meaningful and challenging task. The end-to-end DNN-based methods, though attractive, face the problem of generalization. In this…
U-net Based Direct-path Dominance Test for Robust Direction-of-arrival Estimation
Hao Wang, Kai Chen, Jing Lu
It has been noted that the identification of the time-frequency bins dominated by the contribution from the direct propagation of the target speaker can significantly improve the r…
A robust DOA estimation method for a linear microphone array under reverberant and noisy environments
Hao Wang, Jing Lu
A robust method for linear array is proposed to address the difficulty of direction-of-arrival (DOA) estimation in reverberant and noisy environments. A direct-path dominance test…
Frequency domain TRINICON-based blind source separation method with multi-source activity detection for sparsely mixed signals
Zelin Wang, Jing Lu, Kai chen
The TRINICON ('Triple-N ICA for convolutive mixtures') framework is an effective blind signal separation (BSS) method for separating sound sources from convolutive mixtures. It mak…
RLS-Based Adaptive Dereverberation Tracing Abrupt Position Change of Target Speaker
Teng Xiang, Jing Lu, Kai Chen
Adaptive algorithm based on multi-channel linear prediction is an effective dereverberation method balancing well between the attenuation of the long-term reverberation and the der…
