A Time Domain Progressive Learning Approach with SNR Constriction for Single-Channel Speech Enhancement and Recognition

Zhaoxu Nian, Jun Du, Yu Ting Yeung, Renyu Wang

ICASSP 2022accepted

Single-channel speech enhancement for automatic speech recognition (ASR) has been widely studied. However, most speech enhancement methods conduct over suppression and introduce distortion, which limits performance gains or even deteriorates the back-end performance. The key to solving this problem…

Speaker segmentation using deep speaker vectors for fast speaker change scenarios

Renyu Wang, Mingliang Gu, Lantian Li, Mingxing Xu, Thomas Fang Zheng

ICASSP 2017accepted

A novel speaker segmentation approach based on deep neural network is proposed and investigated. This approach uses deep speaker vectors (d-vectors) to represent speaker characteristics and to find speaker change points. The d-vector is a kind of frame-level speaker discriminative feature, whose dis…
