Kai-Wei Chang 張凱爲
Kai-Wei Chang holds a Ph.D. from National Taiwan University, where he was advised by Professor Hung-yi Lee. He graduated in 2025, with a dissertation titled “Towards a Universal Speech Model: Prompting Speech Language Models for Diverse Speech Processing Tasks”. His recent work includes a comprehensive survey on spoken language models, conducted in collaboration with leading speech researchers.
He has contributed to publications in esteemed speech conferences and journal, including ICASSP, Interspeech, ASRU, SLT and TASLP. Additionally, he has served as a tutorial speaker at ICASSP 2023 and ICASSP 2024, organized the Codec SUPERB Challenge at SLT 2024, and served as Poster Session Chair at ICASSP 2025. He also gained industry experience as a research scientist intern at Meta’s Reality Labs.
