Chenzi Xu

Postdoctoral Research Associate



Chenzi’s research interests lie in phonetics, phonology, speech technologies, and tone languages. Her PhD investigated the prosodic patterns of unstressed syllables in Mandarin accents. Using quantitative modelling methods, it focused on the characteristics of pitch and rhythm, capturing structured variation in pitch with regard to linguistic contexts, information structure, and social identity. Her current interests are in automatic speech and speaker recognition.

My research interests are in phonetics, phonology, speech technologies, and tone languages. I am interested in how different layers of information including speaker-specific characteristics and linguistic meanings are encoded in speech and perceived, using experimental, statistical, and computational approaches. Being a speaker of three tone languages, I am also interested in tonal representation, variation, and change. For more information, feel free to visit my website:, where I publish step-by-step guide on phonetic research topics including forced alignment, ASR, speech corpus, and reference management.
