Si-ioi (Herman) NG | Speech AI and Healthcare

I'm a Research Assistant Professor at the Department of Language and Science Technology, The Hong Kong Polytechnic University. I'm specialised in combining spoken language processing, clinical speech science, and artifiical intelligence to develop resource and tools for speech-based clinical applications (Publicaitons Here).

I'm also an Adjunct Faculty (formerly a Postdoctoral Scholar) at Arizona State University working with Prof. Visar Berisha and Prof. Julie Liss. I obtained my B.Eng and Ph. D at The Chinese University of Hong Kong, advised by Prof. Tan Lee.

Updates:
My recent work focuses on developing an open-source, Cantonese-focused clinical speech processing tool that accelerates speech science research and AI-powered speech therapy. For inquiry please reach out to si-ioi.ng@polyu.edu.hk
