PREVIOUS RESEARCH PROJECTS

  1. PhD “Exploiting Primitive Grouping Constraints for Noise Robust Automatic Speech Recognition: Studies with Simultaneous Speech” - My thesis employed techniques inspired by human auditory processing to recognise speech corrupted with non-stationary noise. The approach is an extension of the Speech Fragment Decoding approach to robust Automatic Speech Recognition (ASR) developed at the University of Sheffield.
  2. Corpus Collection for Development of an Automated Literacy Tutor
  3. Capacity Building in Medical Physics/Bio-medical Engineering Research and Teaching
  4. A statistical machine translation tool to facilitate translations between English and Samoan for tourists
