Paths to Phonological Complexity: Onset clusters in speech production, perception, and disorders
The principal aim of this project is to significantly advance our knowledge of how universal aspects of speech production, motor control and perception are shaped by grammatical differences between the languages of the world. We conduct a cross-linguistic study into the nature of preferred patterns in speech production, their perception and their manifestation in disordered speech. We thereby capitalize on prosodic and phonotactic differences between languages in order to investigate the circumstances under which preferred production patterns may emerge. By examining the perceptual recoverability of preferred production patterns we broaden our understanding of how physiological preferences may be reflected in grammar. Error patterns in apraxia of speech and aphasia allow for new insights into the cognitive and motoric/perceptual components of phonological complexity.
