Projects per year
I trained firstly as a physicist and then as an electronic engineer, and began my career at the UK Government Communications Centre developing signal-processing algorithms. I then joined British Telecoms's research laboratories to work on speech recognition, and spent two years at the speech research unit of the Royal Signals and Radar Establishment (now Qinetiq) at Malvern, where I researched into adaptation of speech recognition algorithms to new speakers. I returned to BT to lead a team of researchers developing speech recognition algorithms for use on the UK telephone network. I joined the School of Computing Sciences at UEA as a lecturer in 1991 and was appointed professor in 2003. My research interests include speech recognition, music processing, audio identification and automatic lip-reading and I am author or co-author of over 100 publications in these fields. I was an invited consultant at AT&T Bell Labs, New Jersey in 1994, a visiting scientist at Nuance Communications Inc., CA, in 2000, and an invited researcher at Apple Inc., CA, in 2010. I have also acted as a consultant and reviewer for several national governments as well as the European Commission, and also consulted for industry. I am an ex committee member of the IEEE Speech and Language Technical Committee.
Since 2017, I have been working on the MRC-funded CAVA project, https://sites.uea.ac.uk/cava-project. This is a collaboration between an ENT surgeon at the NNUH, Mr John Phillips, and Dr Jacob Newman and myself in CMP. The goal is to develop a 24/7 dizziness monitor by monitoring patients' eye movements.

Key Research Interests and Expertise
Stephen Cox is part of the Speech, Language and Audio Processing Group
His principal research interest is in speech processing, especially automatic speech recognition. Current research projects are in the use of speaker adaptation for speech recognition, speech synthesis, confidence measures for speech recognisers and automatic routing of telephone enquiries. He is the author of over 60 papers in the field of speech processing.
