About
I am a phonetician and laboratory phonologist who studies prosody. My work is motivated by fundamental questions about how speakers use prosody to convey meaning and organize utterances. My research questions vary from: How do speakers highlight new, important, or contrastive information (i.e., mark focus) in an utterance? How do they organize speech into cognitive constituents, and do the prosodic boundaries of these constituents interact with focus marking, revealing patterns of speech planning? How is linguistic rhythm encoded across different types of word-level (e.g., lexical stress, lexical pitch accent, lexical tone, or no lexical prosody) and phrase-level (e.g., head- or edge-prominence) prominence systems?
In extending these questions to second language (L2) contexts, I ask how prosody—at both the word and phrase level—is acquired in L2 speech, including whether more salient aspects (e.g., nuclear accents) are acquired earlier than others (e.g., lack of polysyllabic shortening), and to what extent the prosodic patterns observed in L2 production reflect first language (L1) transfer versus general developmental trajectories shared across diverse L1 backgrounds.
I approach these questions using a wide range of methods, including articulatory data from Electromagnetic Articulography (EMA), acoustic analyses, corpus-based studies, and perception experiments. By addressing these questions across typologically diverse languages, my work aims not only to document the prosodic structure of different languages, but to explain why such structures emerge, what cognitive and motor mechanisms give rise to them, and how prosody functions as a core component of both grammar and human communication
Before UCSB, I completed an MA in Linguistics at National Taiwan University and a BA in English at National Kaohsiung Normal University, where I trained and worked as an EFL teacher — a thread that still runs through my interest in second-language prosody.
Research
My research asks how speakers use prosody to mark focus, organize utterances into constituents, and build linguistic rhythm — and how those systems are acquired in a second language. Four threads run through this work.
