Current Projects

  • Speech intelligibility in individuals with dysarthria – what impact do changes in articulation, voice, resonance, rate, and prosody in diseases such as Parkinson disease and oculopharyngeal muscular dystrophy affect listeners’ understanding of speech?
  • Speech intelligibility in second language learners of English – how do differences in articulation, rate, intonation, and stress impact listeners’ understanding of accented speech?
  • The adaptation effect in repeated readings by people who stutter – what changes in speech production are associated with the reduction of disfluency over repeated readings of the same passage?
