Research Interests

  • Perceptual learning: Listeners’ adaptation to variability in the speech signal, including foreign-accented speech and degraded speech.
  • Speech intelligibility: The influence of factors about the talker, listener, and listening environment on communication success.
  • Developmental speech perception: Children’s perception of speech, including the cognitive-linguistic skills underlying the ability to perceive dialects and accents.
  • Hearing loss, dyslexia, and bilingualism: The influence of hearing loss, dyslexia, and bilingualism on the perception of speech.
