Haoran Wang

I am now a senior undergraduate student at ACM Honors Class, Shanghai Jiao Tong University majoring in Computer Science.

Now I am a visiting student at WAVLab affiliated with LTI/CMU, advised by Prof. Shinji Watanabe. During my junior year, I am very fortunate to work with Prof. Kai Yu at X-LANCE Lab.

My research interests lie in generative audio and speech processing, especially in neural audio codecs and speech language models. My long-term goal is to pioneer a universal audio foundation model capable of holistically understanding and generating the full spectrum of sound, including speech, music, and complex acoustic scenes, while making these models high-fidelity, controllable, and efficient.

Feel free to check out my CV and shoot me an email if you'd like to chat.

Selected Publications

My research interests lie in speech and audio processing, especially neural codecs and speech language models for complex acoustic environments. I am interested in building general and high-fidelity speech representations that are useful for both reconstruction and downstream tasks. Representative works are highlighted.
