SSC: 106 bit/s Ultra-low Bitrate Semantic Speech Coding

Renjie Jia, Zhiqiang He, Kai Niu, Zixuan Xiao, Yonghui Liu, Jianbing Liu

ICASSP 2025accepted

Currently, balancing low bitrate coding with speech quality is a highly debated topic in the research community. At very low bitrates, existing methods often fail to maintain speech naturalness, intelligibility, and personalization. To address this issue, we introduce an innovative ultra-low bitrate…

Wireless Deep Speech Semantic Transmission

Zixuan Xiao, Shengshi Yao, Jincheng Dai, Sixian Wang, Kai Niu, Ping Zhang

ICASSP 2023accepted

In this paper, we propose a new class of high-efficiency semantic coded transmission methods to realize end-to-end speech transmission over wireless channels. We name the whole system as Deep Speech Semantic Transmission (DSST). Specifically, we introduce a nonlinear transform to map the speech sour…
