Research Interests

The application of automatic speech recognition in domains where they may be limited training data.


2010, PhD in Automatic Speech Recognition, University of Edinburgh.

2005, MPhil, Computer Speech, Text and Internet Technology, University of Cambridge.

2002, BA, Mathematics, University of Cambridge.


I am a senior research associate in automatic speech recognition at the Centre for Speech Technology Research, in the School of Informatics at the University of Edinburgh, where I completed my PhD in 2010. Please see the CSTR pages for my contact details and publications. My (possibly out-dated) curriculum vitae is also available.

I came to Edinburgh after completing the MPhil in Computer Speech, Text and Internet Technology at Cambridge University, where I took my first degree, in Mathematics, a few years earlier.

My primary speech recognition research is conducted within the EPSRC-funded, Natural Speech Technology project, a five-year programme grant held jointly with the University of Cambridge and University of Sheffield. Our aim is to significantly advance the state-of-the-art in speech technology. I am particularly involved in the themes of structuring diverse data and generating systems with wide domain coverage, for example, through the use of adaptive neural network features. One of our primary tasks has been dealing with highly diverse broadcast data from the BBC (See my publications for more details.) I am an organiser of the MGB challenge for ASRU 2015.

I am a firm believer in the commercial value of speech technology, and passionate about bringing cutting-edge advances in the research sphere to commercial benefit as rapidly as possible. Notably in this area I have worked as a consultant for France Telecom's R&D labs in London, advising on the adoption of new technologies in speech recognition and synthesis, work which lead to a Knowledge Transfer Partnership funded by the UK government's Technology Strategy Board. I also provide consultancy services to start-up companies requiring speech technology expertise.

I also have a role as Senior Speech Recognition Scientist at Quorate Technology Ltd, a recent spin-out from the University of Edinburgh.
