Prof Young’s research is concerned with the theory and application of statistical approaches to speech and language processing and their use in human computer interfaces. This includes speech recognition and synthesis, semantic decoding, dialogue management and natural language generation. The focus of his current work is designing spoken dialogue systems which can automatically adapt and scale on-line in interaction with real users.
The techniques being developed are based on the framework of partially observable Markov decision processes (POMDPs) and they use expectation propagation for on-line parameter estimation and Gaussian process-based reinforcement learning for rapid policy optimisation.
Current projects include a collaboration with General Motors, in which statistical dialogue modelling techniques are being used to overcome the limitations of speech recognition in high noise; and the EU Parlance project which is seeking to extend existing spoken dialogue technologies to work in open domains and support significant levels of personalisation.
