Yun Wang (Maigo)

Yun Wang is my real name and Maigo is my nickname. You can call me either Yun or Maigo.

Who I am and why I'm here

I graduated from the Department of Electronic Engineering of Tsinghua University in 2010. Now I am a second-year master student at LTI, CMU.

I am interested in technologies about speech, natural language, and music. Currently I'm working with Prof. Qin Jin on speaker identification.

I'm taking this course because I've taken Language & Statistics, which gave me inspiring insights into language.
