Our current work addresses the following questions:


  • Does speaking in unison, also known as choral speaking, help people with aphasia speak more fluently? Whom does this work for, and how does it work? View our NIH-funded study.


  • Do adults with apraxia of speech (AOS) speak more clearly or fluently when they cannot hear themselves? Are people with AOS using their own auditory feedback effectively?


  • To what extent is the ‘melody of speech’ (prosody) preserved in people with aphasia, especially in speakers with difficulty using grammar (syntax)? How much prosody can a speaker ‘do’ without syntax?


  • What is the prevalence and nature of language and cognitive deficits after stroke, and how do these evolve over time? How does impaired language (aphasia) influence performance on common measures of cognition used after stroke, and how does impaired cognition influence performance on language measures?
