In the Speech Production Research Laboratory, we study speech – as it is perceived and produced – by adults and children. There is a particular focus on the speech of brain-injured talkers with disorders known as aphasia and apraxia-of-speech. We are also exploring whether visual feedback concerning articulatory movement can be used as a new form of intervention/treatment for speech disorders after stroke.

We recruit members of the greater Dallas/Fort Worth community, including veterans and individuals with brain damage resulting from stroke.
We also recruit UT Dallas students as healthy control subjects. Children are often tested, including children recruited from the Callier educational programs.
Announced each semester. Contact Dr. Katz for times.
