Hi, welcome to my page.
I’m Zirui Li (李孜睿). I’m a PhD student from School of Electrical Engineering at Aalto University, Finland, working with Prof. Mikko Kurimo and Dr. Lauri Juvela. My research interests include Controllable Text-to-Speech and Voice Conversion (TTS & VC), Automatic Speech Recognition (ASR) on low-resource languages, and real-time conversational systems.
Before joining Aalto University, I was a Backend Software Engineer at Justeat Takeaway.com. I obtained my Master’s degree from Delft University of Technology, the Netherlands, where I worked with Prof. Odette Scharenborg on Inclusive Automatic Speech Recognition. I obtained my Bachelor’s degree from Tianjin University, China.
