About

I am a research scientist at ByteDance Seed. Prior to joining ByteDance, I worked as a research intern at Microsoft Research Asia. I received my Ph.D. degree in speech & language processing from Human-Computer Communications Laboratory (HCCL), The Chinese University of Hong Kong (CUHK), supervised by Prof. Helen Meng. Before that, I obtained my M.Phil. from the Institute of Automation, Chinese Academy of Sciences (CASIA), supervised by Prof. Jie Tian, and my Bachelor's degree from Harbin Institute of Technology (HIT).

My research interests focus on language modeling for speech synthesis and the integration of speech with large language models. I am also working on speech processing and recognition.
