• Motor speech disorders in adults and children, including deficits associated with development and those that accompany neurological disease (e.g., Parkinson’s, dysarthria, apraxia)
• Variability and consistency of speech production in children and adults, from sensory and motor aspects of speech
• Sources of variation that emanate from both sensory and motor aspects of speech
• Speech learning and the effects of auditory perception on speech production
