Listening Effort and Mental Fatigue
Aim 1 of my F32 award focuses on understanding how listeners with and without hearing impairment use speech context to repair a misperception, and how this process affects the timing and duration of listening effort. This work is in press at Trends in Hearing (doi: 10.1177/23312165251320789) and will be made available soon. A poster presented at CIAP in 2023 is shown below and can be downloaded here.
Aim 2 is focused on understanding if momentary increases in listening effort directly accumulate into mental fatigue or if listening fatigue is explained by other factors. A poster with the current update to this project was presented at the 2025 American Auditory Society (AAS) meeting and is shown below. It can also be downloaded here
Acoustic Characteristics of Speaker Intelligibility
The goal of the present work is to validate a set of widely used acoustic measures that have been found to predict talker intelligibility using a new, racially diverse corpus of native speakers of American English. Previous work has found changes in F0 and larger vowel spaces to be associated with higher sentence intelligibility. Here, we examine whether these same acoustic features can be generalized to a more racially diverse population of talkers. A poster with the current update to this project is shown below and can be downloaded here.
