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.
