Summary
👤
Senior🎓
Top SchoolHexin Liu is a research-focused speech scientist with eight years of experience advancing spoken language identification, diarization, and multilingual/code-switching ASR. Currently a Research Fellow at Nanyang Technological University after a PhD in Speech and Language Recognition, he blends deep academic rigor with industry experience gained as a Speech Recognition Scientist intern at ByteDance. His work centers on practical multilingual systems that tackle real-world challenges like code-switching and language identification in noisy, mixed-speaker conditions. Based in Singapore, Hexin brings strengths in both modeling and evaluation, bridging signal processing and end-to-end neural approaches. Less obvious but impactful: he frequently integrates cross-lingual insights from his electrical engineering background to improve robustness in low-resource scenarios.
