Experience
- Undergraduate Research2024.09 — 2025.12College of Engineering, Southern University of Science and TechnologyExploring the impact of paralinguistic signals in dialogue datasets on language model performance across tasks.
- Department of Electrical and Computer Engineering, North Carolina State UniversityConducted 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.
- Visiting Research Student2025.09 — 2025.12School of Engineering, Hong Kong University of Science and TechnologyDeveloping 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.
- Research Intern2025.11 — 2026.03Lyra Lab, Tencent Music EntertainmentDeveloped a lyric-aware symbolic music foundation model with attribute-wise masked pretraining and hybrid music–language embeddings, improving vocal-centric understanding while maintaining strong performance on symbolic music classification benchmarks. Also developing a symbolic music generation algorithm that transforms lead sheets into full piano arrangements by modeling harmonic realization, voicing structure, and accompaniment texture.
Publications
- Investigating the Representation of Backchannels and Fillers in Fine-tuned Language Models2025preprintAuthors: Yu Wang, Leyi Lao, Langchu Huang, Gabriel Skantze, Yang Xu, Hendrik BuschmeierThis 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.
- LyricMidi: Joint Music–Language Pretraining for Symbolic Music Understanding2026ICME under reviewAuthors: Langchu Huang, Yiliang Jiang, Ying Chen, Lingcheng Kong, Weifeng ZhaoThis paper proposes a unified music–language pretraining framework that jointly models symbolic music events and lyrics. The model achieves consistent improvements on vocal-centric symbolic music understanding tasks while preserving general music representation performance.
