Speech, Phonology and Linguistics Group

The group has explored a range of acquired speech disorders, including Foreign Accent Syndrome, and investigative techniques for speech, such as ultra sound. It has explored the effects of accent on speech processing and rhotic sound production. A recent theme has been the contribution of the cerebellar to language and related cognitive processing, with novel insights published in major journals such as Cortex and The Cerebellum.

Research has also focused on applied linguistics, with two main themes: clinical linguistics and gender discourse in speech and language therapy. For example, the group is applying linguistic and phonetic analysis to further our understanding of aphasia.

The group has attracted funding from the Nuffield Foundation and the Royal Flemish Academy of Belgium.
