Past Members, Research Students

I completed my Ph.D. in February 2018 in the Department of Computer Science at the University of Sheffield under the supervision of two great scholars, Professor Jon Barker and Professor Thomas Hain in the SPandH and MINI groups. My PhD thesis title is “Robust Phase-based Speech Signal Processing; From Source-Filter Separation to Model-Based Robust ASR”.
