Experience

  • Undergraduate Research
    2024.09 — 2025.12
    College of Engineering, Southern University of Science and Technology
    Exploring the impact of paralinguistic signals in dialogue datasets on language model performance across tasks.
  • Research Intern
    2025.07 — 2025.08
    Department of Electrical and Computer Engineering, North Carolina State University
    Conducted research in the ARoS Lab under Prof. Lobaton. Designed a data collection protocol and built a dual-modal cough-speech dataset using both air and bone conduction. Developed a dual-path contrastive learning architecture for robust cough-speech detection.
  • Exchange Student
    2025.09 — 2025.12
    School of Engineering, Hong Kong University of Science and Technology
    Developing a multitrack symbolic music codec for LMs, aiming to design compact discrete representations to enhance symbolic music understanding and generation. The work explores residual vector quantization, interleaved ABC notation, and multimodal alignment for controllable, musically coherent outputs.

Publications

  • Investigating the Representation of Backchannels and Fillers in Fine-tuned Language Models
    2025
    ACL (under review)
    Authors: Yu Wang, Leyi Lao, Langchu Huang, Gabriel Skantze, Yang Xu, Hendrik Buschmeier
    This work investigates how fine-tuning strategies enhance language models’ ability to represent and generate backchannels and fillers in dialogue. Empirical analyses demonstrate improved clustering quality and more human-like language generation, showcasing the potential for adapting general LMs into pragmatic-aware conversational models.
