My Career Path and Research in Prosodic Entrainment in Dialogue
In this talk I will first describe my own pretty unusual path from History to Computer Science as well as some things I learned along the way that might be useful for young researchers. I’ll next talk about a topic my students and I have worked on for many years -- entrainment: In conversation, speakers often adapt aspects of their speaking style to the style of their conversational partner. This phenomenon goes by many names, including entrainment, adaptation, and alignment. I will describe results from experiments on English and Mandarin prosodic entrainment in the Columbia Games Corpus and in the Tongji Games Corpus, large corpora of speech recorded from subjects playing a series of computer games. I will also discuss experiments relating entrainment to several social dimensions, including likeability and dominance, and its relationship to higher level prosodic features. This is joint work with Štefan Beňuš, Nishmar Cestero, Agustín Gravano, Rivka Levitan, Sarah Ita Levitan, and Zhihua Xia.

The Use of Spoken Language Technologies for Screening Neurocognitive Disorders (NCD)
This talk shares part of my journey in spoken language technologies research, starting from developing computer-aided pronunciation training technologies to support Chinese learners of English, to the development of AAC (augmentative and alternative communication) devices/technologies such as the e-communication book, dysarthric speech recognition, voice reconstruction, to our recent research in spoken language technologies for screening neurocognitive disorders (NCD). With the global population ageing rapidly, a key health concern lies in NCDs – a common form being Alzheimer’s Disease (AD). NCDs are particularly prominent in older adults, which has an insidious onset followed by gradual, irreversible deterioration in memory, communication, thinking and other cognitive functions. Thus, early detection of NCDs is crucial for timely intervention to slow down disease progression. This challenge motivated the formation of our interdisciplinary team, with researchers in engineering, geriatrics, linguistics, neurology, psychology and public health. We will present our recent research work in spoken language technologies to analyze English and Chinese recordings from neuropsychological assessments for discriminating between healthy controls and participants with NCD. Encouraging experimental results support the viability of fully automatic screening. We will also describe ongoing research on naturalistic data collection and spoken language interface development for older adult users.

Who Is Responsible for Responsible AI?
With widespread application of intelligent systems in the society today, we are facing unprecedented demands to make signal processing and AI algorithms more robust & safe, more fair, more secure, more explainable and more accountable. In this talk, I will give an introduction to such challenges in our research field today and describe my personal experience in awakening to the need of making AI "responsible". I will discuss the role and impact of a signal processing researcher in the new era of Responsible AI.
