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 to upload research outcomes.

Here is my Resume.



Slides for SPSC webinar presentation on “Using vocoders to create spoofed training data for speech spoofing countermeasures” can be found in Slide page. This is a presentation for ICASSP 2023 paper. The code, pre-trained models, and other resources are available at this repo.


Jupyter notebook of the tutorials on speaker anonymization is available at Slide page.


The materials for ICASSP short course on neural vocoders are available on Google colab. The old contents are re-edited, and new contents are available (including NSF-HiFiGAN).


Slides for JST Science Agora talk on speech spoofing detection is available: Agora PDF and Agora PPT. There are many spoofing audio samples under various conditions. You can try to detect which one is spoofed.


The slides for the talk on speech anti-spoofing and anonymization are uploaded. Two Speech Security Issues after Speech Synthesis Boom, 2021 Dec, a talk given at CCF. download from here.


The ASVspoof 2021 Workshop, an official Interspeech 2021 satellite event, will be held online in the form of a Zoom Webinar on September 16th, 2021.

The tentative technical program is available from the ASVspoof website

The registration link is here
