About the AAC Lab

The Augmentative and Alternative Communication (AAC) Lab is housed in UT Austin’s Department of Speech, Language, and Hearing Sciences in the Moody College of Communication. Our research aims to improve the efficacy of technologically based AAC interventions for persons with severe speech and language impairment as a result of developmental and acquired conditions. Our work primarily focuses on adults with neurogenic communication disorders such as aphasia and children diagnosed with autism spectrum disorders and other developmental disabilities. We use a combination of behavioral, perceptual, and electroencephalography (EEG) measures to address these lines of inquiry. Ongoing research projects include investigations into the efficacy of AAC interventions in persons with aphasia, variables that influence outcomes of interventions with a speech generating device as part of a treatment package, and the efficacy of EEG-based brain-computer interface (BCI) system for communication.
