The overall scientific objectives of HOARSE are to gain a better understanding of speech production and hearing and to use this understanding to explain the perceptual organisation of sound and improve speech technology. The project has five inter-related themes, addressing the following questions:
    1. How are sound mixtures perceptually organised, and how can this Auditory Scene Analysis can be used in speech recognition?
    2. How does the Auditory System handle reverberant conditions, and how can models of this processing be used for speech enhancement?
    3. How is speech production related to speech perception and cerebral speech processing, and how can this knowledge be integrated into speech recognition systems?
    4. How can Automatic Speech Recognition algorithms take advantage of the work in Themes 1 and 2, for use in natural listening conditions?
    5. How can the results of other themes be exploited in speech recognition applications which require robust performance  in adverse conditions and/or processing of sound mixtures?
