Research Interests

My research interests include speech recognition and spoken dialogue systems. I am the inventor and original author of the HTK Toolkit for building hidden Markov model-based recognition systems (see http://htk.eng.cam.ac.uk), and I co-developed the original HTK large vocabulary speech recognition system which has figured strongly in DARPA/NIST evaluations since it was first introduced in the early nineties. More recently I have worked on statistical dialogue systems and pioneered the use of Partially Observable Markov Decision Processes for modelling them. I also have active research in emotion generation and HMM synthesis.
