Kai-Wei Chang (張凱爲)

Kai-Wei Chang is a third-year Ph.D. student at National Taiwan University, supervised by Professor Hung-yi Lee. His research focuses on speech self-supervised learning and speech language models within the prompting paradigm. Particularly, He focuses on reshaping the speech foundation model into a comprehensive universal speech processing framework.

He has contributed to publications in esteemed speech conferences including ICASSP, Interspeech, ASRU, and SLT. Additionally, he has served as a tutorial speaker at ICASSP 2023, ICASSP 2024 and gained valuable experience as a research scientist intern at Meta’s Reality Labs.
