Optimising Neural Speech Codecs for 300bps Communication using Reinforcement Learning
Junyi Wang, Chi Zhang, Jing Qian +4
In bandwidth-constrained communication such as satellite and underwater channels, speech must often be transmitted at ultra-low bitrates where intelligibility is the primary object…
ClariCodec: Optimising Neural Speech Codes for 200bps Communication using Reinforcement Learning
Junyi Wang, Chi Zhang, Jing Qian +4
In bandwidth-constrained communication such as satellite and underwater channels, speech must often be transmitted at ultra-low bitrates where intelligibility is the primary object…
Gumbel Distillation for Parallel Text Generation
Chi Zhang, Xixi Hu, Bo Liu +1
The slow, sequential nature of autoregressive (AR) language models has driven the adoption of parallel decoding methods. However, these non-AR models often sacrifice generation qua…
VoiceBridge: General Speech Restoration with One-step Latent Bridge Models
Chi Zhang, Kaiwen Zheng, Zehua Chen +1
Bridge models have been investigated in speech enhancement but are mostly single-task, with constrained general speech restoration (GSR) capability. In this work, we propose VoiceB…
