I am Xin Wang, a postdoc researcher at Yamagishi Lab, National Institute of Informatics (`NII `_), Japan.
I am studying speech processing and machine learning, and I learned a lot from my supervisors at NII and USTC and many colleagues around the world.
My `Researchmap site `_ and `Google Scholar page `_. Researchmap is the official website for researchers in Japan.
Here is my :ref:`label-resume`.
