in a transparent head while a subject talks — for the purposes of treating speech errors and teaching foreign language sounds. This work has been conducted in partnership with Vulintus and with support from the National Institutes of Health (NIH). The UT Dallas Speech Production Lab is currently updating the program to use updated versions of Unity and adding support for more features and hardware.</p><p><img src="/assets/system-architecture-600.254c8a7e.jpg" alt="System Architecture"></p><iframe width="560" height="315" src="https://www.youtube.com/embed/9uHqIRs7ZjM" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen style="display:block;margin:auto;"></iframe><p>This video shows a talker with WAVE sensors placed on the tongue hitting a virtual target sphere located at the alveolar ridge.
