• Mark Liberman

    Mark Liberman’s recent research areas include the phonology and phonetics of lexical tone, and its relationship to intonation; gestural, prosodic, morphological and syntactic ways of marking focus, and their use in discourse; formal models for linguistic annotation; information retrieval and information extraction from text.

  • Jianjing Kuang

    Jianjing Kuang’s recent research areas include the multidimensionality of tonal contrasts, phonation (production, perception and phonological representation), laryngeal articulations across languages, experimental fieldwork (Tibeto-Burman, Mayan, Hmong-Mien languages), computational modeling (mapping between production and perception), and prosody (intonation patterns and prosody in sentence processing).


  • Martin Ho Kwan Ip

    Martin is interested in how speech processing can be shaped by both language-universal mechanisms as well as our experience with our native language. He addresses this question by adopting a cross-linguistic approach. At the Phonetics Lab, he studies how Cantonese listeners attend to the immediate intonation contour to predict the prosodic forms of upcoming words. In his second line of work, Martin also studies how speakers across languages prioritize different prosodic cues in sentence disambiguation.


  • Aletheia Cui

  • Wei Lai

    Wei is interested in speech perception, phonetics and psycholinguistics. Most of her recent studies focus on the perception and processing of variability in speech, investigating how listeners integrate contextual cues with linguistic (phonological, phonotactic and lexical cues) and nonlinguistic (speaker specificity, gender, vocal effort) attributes to uncover linguistically meaningful units from various raw signals in their perception and processing behaviors. She also has a long-lasting interest in tonal and suprasegmental aspects of speech.

  • Danni Ma

  • Ruaridh Purse

    Ruaridh works on phonetics, phonology and sociolinguistics. In particular, his recent research has focused on articulation, including the articulatory realities of variable phenomena and exploring systematic articulatory variation. He is currently using Electromagnetic Articulography (EMA) data to investigate these areas.

  • Nari Rhee

    Nari is interested in phonetics, computational linguistics and mathematical linguistics. Nari’s recent project is on the distribution of a retroflex lateral allophone in Korean and how the retroflexion plays a role in r-l perception.

  • Ollie Sayeed

    Ollie is interested in diachronic explanations of sound patterns, and in the relationship between misperception and sound change.

  • Jia Tian

    Jia is interested in the phonetics and phonology of tones. Her current work focuses on the phonation and tone sandhi in various Chinese Wu dialects.

  • Hong Zhang

    Hong’s research interests lie in the realm of phonetics and in phonology and beyond. In particular, he has been engaged in projects investigating the acoustics of vowel nasality and voice quality, and aspects of the fundamental frequency (F0) of Mandarin, Cantonese and Thai. His current work is mostly focused on speech disfluency in both normal population and patients with neural degenerative diseases and stuttering.


  • Ping Cui

    Ping is a Ph.D. candidate at Peking University. She is also a visiting student at Penn for the time being. Ping is interested in Phonetics, Phonology and Chinese dialectology. Her recent project is mostly focused on tone sandhi and intonation in Northeastern Mandarin.
