Augmentative and Alternative Communication Lab: Augmentative and Alternative Communication Lab

About the AAC Lab

The 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 augmentative and alternative communication interventions for persons with severe speech and language impairment as a result of developmental and acquired conditions. Our research primarily focuses on adults with neurogenic communication disorders such as aphasia and children diagnosed with autism spectrum disorders and other developmental disabilities.   We study the factors that influence the outcomes of technology-based AAC interventions. We use a combination of behavioral, perceptual, and electroencephalography 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 system with persons with developmental and acquired communication impairments. 

Our work would not be possible without the generous contributions of our clinicians and volunteers.

Trainings at the AAC Lab

This October, the AAC Lab hosted three trainings from Tobii Pro, Dynavox, and Intendix. Members of the lab got hand on experience to use the new eye tracking and brain-computer interface system technology.

AAC Display Configuration Pilot Study

This pilot study with our collaborator Kris Brock was a preliminary inquiry into the perceived communicative competence of persons with chronic aphasia communicating with AAC devices with various display configurations. Check out the paper in Aphasiology!
