Sibo Tong

Short Biography

I am a PhD student at Ecole Polytechnic Federale de Lausanne (EPFL) in Electrical Engineering (EDEE) and research assistant at Idiap Research Institute under Dr. Philip N. Garner. I am funded by SUMMA project which aims to integrate stream-based media processing tools (including speech recognition and machine translation) with deep language understanding capabilities

My research focuses on building automatic speech recognition (ASR) systems for low-resourced languages.
