This project examines several issues related to speech perception under conditions of distortion (i.e., hearing loss, hearing aid amplification, dialect, foreign accent, etc). Current work is focused on cross-dialect perception and talker familiarity, and how they interact with hearing loss of different types. This research is funded by NIDCD flowthrough funds to Pamela Souza at Northwestern University (NIH grant R01DC006014), and is a collaboration with Northwestern's Hearing Aid Lab.
