Chenyu Li
I am a PhD student at the Laboratoire de Linguistique Formelle (Université Paris Cité and CNRS).
My research interests include the phonetics–phonology interface, dynamic modelling of speech, sociophonetics, cross-variety study, corpus-based research, and laboratory phonology.
I investigate the temporal patterns of vowel production and the relationships between acoustic and articulatory trajectories, e.g., f0 and formants. My work combines generalized additive mixed models (GAMMs), Bayesian regression, functional data analysis (fPCA, Function-on-Function mapping), and machine learning, with theoretical perspectives on speech dynamics, including Articulatory Phonology.

Diphthong Dynamics under Lexical Tone: Cross-Dialectal Evidence for Category-Specific f0–F1 Coupling
Supplementary documents and example R scripts accompany this study of tone–vowel relations in Mandarin diphthongs.
The materials include:
- Supplementary methods, additional results, and robustness analyses.
- GAMM summaries, diagnostic checks, and model comparisons.
- Core R scripts for GAMMs, functional principal component analysis (fPCA), and function-on-function regression (FoF).
