Projects
Language Documentation and Revitalization with Sonya Bird (University of Victoria, Canada). Our aim with this project is to examine acquisition trajectories for L2 learners of Hul’q’umi’num’. We are comparing spectral moments from fricatives and affricates for L2 learners at different stages of acquisition and comparing them to L1 speakers. Our goal is to understand acquisition trajectories and how internalized L2 structure develops with experience. We are also examining the complex and rare posterior fricative system (3-way velar/uvular fricative) in Hul’q’umi’num’. Our goal is to understand how this system is maintained through spectral cues. |

The production and perception of liquids with Jessamyn Schertz (University of Toronto Mississauga, Canada) and M. Irfana (Netaji Subhash Chandra Bose Medical College, India).
We are examining the link between the acoustic-perceptual characteristics of liquids in a cross-linguistic context. The aim of the study is to understand what listeners are perceiving when they hear liquids. The larger aim is to understand the acoustic-perceptual cues and how those shape phonological inventories. |
