About me

Image title

I am a Professor in Computer Science at the University of Sheffield, and a member of the Speech and Hearing Research Group.

My research interests include speech recognition by humans and machines, hearing-aid signal processing for speech and music, audio-visual speech processing, machine listening and the application of machine learning to audio processing.
