I’m currently a sixth year PhD student at the Language Technologies Institute of Carnegie Mellon University. I am working with Prof. Alex Rudnicky on Speech Recognition. I got my Bachelor and Master degrees from University of Science and Technology of China, where I worked with Prof. Renhua Wang on Speech Synthesis.
