About Me
Hi, I'm Tuan Nguyen — a Research Engineer with a passion for bridging theory and practice in AI and speech technology. I currently work at a research agency in Singapore, focusing on multilingual, low-resource, and code-switching speech recognition for 11 Southeast Asian languages.
I earned my degree early from a 4-year Data Science program in Vietnam, and have since published multiple first-author papers at top-tier conferences like Interspeech. My research interests lie in building robust, multilingual models and deploying efficient AI systems for real-world use.
I’m currently aiming for long-term growth in both academia and industry, with a goal of pursuing a Ph.D. at a top global university. Then working as a Research Scientist on interesting and high-rewards projects.

Projects
Automatic Pronunciation Error Detection (APED)
Implementation - Presentation | Aug 2022 - Dec 2022
Developed an AI system for automatic pronunciation error detection (for non-native speakers learning English) using semi-supervised learning and the LCS algorithm, based on state-of-the-art research published in the related field.
Achieved a significant reduction in Phoneme Error Rate (PER) from 17% (teacher model) to 12% (student model) on the Phoneme Recognition task using the Libri-Light and LibriSpeech dataset.
Key Learnings: ASR, Noisy Student Training, wav2vec2.0, Conformer, Self-Supervised Learning (SSL).
