I am an undergraduate student at Turing Class, Chu Kochen Honors College, Zhejiang University, majoring in Artificial Intelligence. Currently, I work in the Audio Research Team at Zhejiang University, under the supervision of Prof. Zhou Zhao.
My research interest lies on Multi-Modal Generative AI, with a particular focus on Speech Synthesis and Spatial Audio Generation. My work aims to build immersive auditory experiences through advanced generative modeling (e.g., Flow Matching). Currently, I have several papers published or under review at top-tier venues including NeurIPS, ACM MM, and ACL.
I am always open to potential collaborations and seeking opportunities to push the boundaries of AI. Contact me for any exciting projects or discussions!

CSAVocoder: A Causal Spatial Audio Vocoder Towards Real-Time Spatial Audio Generation
#Zhiyuan Zhu, #Han Wang, et al.
- We introduce CSAVocoder, a strictly causal streaming neural vocoder. It features a Spatial Adaptor to fuse pose information and a Spatial Consistency Discriminator to explicitly supervise inter-channel phase and level differences.
- The model achieves high-fidelity waveform reconstruction while preserving precise spatial rendering, all within a constant memory overhead suitable for real-time streaming.
Comprehensive Benchmarking of Long-Form Speech Generation in Diverse Scenarios
#Changhao Pan, #Rui Yang, #Han Wang, et al.
- We propose LFS-Bench, a standardized benchmark decomposing “long-form quality” into acoustics, semantics, and expressiveness. It includes 1,101 samples spanning 17 diverse scenarios (e.g., dialogues, audiobooks).
- Our extensive experiments reveal that current SOTA models still struggle significantly with consistency and hierarchy in highly expressive scenarios compared to real recordings.
