Relationship between perception and production (funded by NSF BCS 1734166)
In this set of projects, we examine how perception and production are related during learning. Some projects under this larger project include:

  • Production-based sources of disruption in perceptual learning (with Arty Samuel – Stony Brook University and The Basque Center on Cognition Brain and Language)
  • The role of explicit category knowledge in mediating the relationship between the two modalities (with Misaki Kato)
  • Production learning in the absence of perceptual learning
  • Emergence of learning in perception and production.

Variability in Non-Native Speech

  • In this set of projects, we examine whether non-native speakers are more or less variable than native speakers in their language production. We ask whether we might be able to predict cases in which learning appropriate variability in a new language might be particularly difficult. Some projects under this larger project include:
    • Variability in native and non-native speaking rate (with Tuuli Morrill)
    • Variability in speech of native English and Mandarin learners of Japanese (with Charlotte Vaughn & Kaori Idemaru – University of Oregon)

Speech Rate, Speech Rhythm, and Non-Native Speech

  • In this set of projects, we examine whether expectations derived from speaking rate and speech rhythm are different when listening to non-native speakers or when non-native listeners hear native speakers. Portions of this project are being conducted in collaboration with Laura Dilley (Michigan State University) and Tuuli Morrill.

Lexically Conditioned Phonetic Variation

  • In this set of projects, we examine how lexical properties of a word (e.g., neighborhood density and word frequency) influence phonetic variation in those words. Some projects under this larger project include:
    • Frequency and neighborhood density effects in children’s speech (with Katherine White – University of Waterloo)
    • Metrics of neighborhood density (with Matt Goldrick – Northwestern University & Melinda Fricke – Penn State University)

A number of other projects are also currently taking place in the lab. Some of these include:
