Tianxin Xie (谢添鑫)

I am a PhD student at the AI Thrust, Information Hub, Hong Kong University of Science and Technology (Guangzhou), advised by Prof. Li Liu. I received my B.E. degree in Computer Science from Hunan Normal University, and my M.S. degree in Computer Science from the University of Chinese Academy of Sciences, advised by Prof. Hu Han.

My research focuses on text-to-speech and speech LLMs, with particular emphasis on controllable speech synthesis, speech reasoning and interaction in LLMs, and multi-modal audio generation.
