Introduction
Dongheon Lee
Ph.D. student in Electrical Engineering at Korea Advanced Institute of Science and Technology (KAIST), in Smart Sound Systems under the supervision of Prof. Jung-Woo Choi. My research is focused on deep learning-based single/multi-channel speech enhancement and source separation. My interests also include microphone array signal processing, AR/VR, and automatic speech recognition (ASR).
