About Me

I am a doctoral student in the Multimodal Speech Processing group at Multimodal Computing and Interaction (M2CI) under the supervision of Dr. Ingmar Steiner. Before that, I did my M.Sc Computer Science from Saarland University and B.Sc Computer Science from Islamia College Peshawar, Pakistan.

My research interests include:

  • Speech segmentation
  • Segmentation behaviour analysis
  • Acoustic modeling
  • Audio Analysis
  • Automatic speech recognition
