Yi Liu (刘艺), Ph.D.
|Email: email@example.com |
I'm now a software engineer working on speech processing in ByteDance AI Lab. My research interests include speaker recognition and diarization, speech recognition, and other speech/audio processing technologies. I am also the reviewer of INTERSPEECH and ICASSP.
I received my Ph.D. degree in Tsinghua University under the supervision of Prof. Jia Liu in 2020, with the dissertation Research on Speaker Embedding Extraction Methods based on Deep Learning. I received my M.E. degree in Tsinghua University in 2018 and the B.E. degree in Wuhan University in 2012. I was a visiting student in Cambridge University Engineering Department from July to December 2018.
