RRPO: Robust Reward Policy Optimization for LLM-based Emotional TTS

Cong Wang, Changfeng Gao, Yang Xiang +7

Differentiable reinforcement learning (RL) frameworks like DiffRO offer a powerful approach for controllable text-to-speech (TTS), but are vulnerable to reward hacking, particularl…

Explore the Reinforcement Learning for the LLM based ASR and TTS system

Changfeng Gao, Yabin Li, Keyu An +4

In recent years, large language models (LLMs) have played an important role in automatic speech recognition (ASR) and text-to-speech (TTS) systems. While reinforcement learning (RL…

CosyVoice 3: Towards In-the-wild Speech Generation via Scaling-up and Post-training

Zhihao Du, Changfeng Gao, Yuxuan Wang +19

In our prior works, we introduced a scalable streaming speech synthesis model, CosyVoice 2, which integrates a large language model (LLM) and a chunk-aware flow matching (FM) model…
