Bernd T. Meyer

Hi, welcome to my academic home!

I am working in the Medical Physics group at the University Oldenburg. My thesis and my current research are about improving automatic speech processing by applying principles of the human auditory system.

Research Interests

  • Robustness of automatic speech recognition (ASR)
  • Auditory feature extraction for ASR
  • Modeling human speech perception
  • Comparison of human and automatic speech recognition
  • Application of novel feature concepts on tasks in speech research (e.g., speech activity detection or speaker recognition)

I've been involved in the development of the Oldenburg Logatome Corpus (OLLO), which is freely available for research. Follow this link for a description: http://medi.uni-oldenburg.de/ollo
