The goal of this research study is to evaluate a novel approach to improving speech recovery in those with acquired apraxia of speech. We will enroll participants with apraxia of speech resulting from stroke or brain injury to complete several tasks and intervention. Testing will take place four times over the course of the study and intervention will take place 5 days a week for 16 weeks. Overall, you can expect to spend up to 17 weeks participating in this study.

Adverse events
Frequency and severity of adverse events will be monitored and evaluated for severity and impact on attrition.
Time frame: 6 months
Compliance
Percentage of the population that remains engaged in the study and completes all stimulation sessions.
Time frame: 6 months
Change in speech production scores
Primary outcomes for this aim include the learning trajectory over 8 weeks of speech therapy as measured by weekly probes and the WAB when intervention is combined with taVNS versus control stimulation to determine the effect of taVNS on re-learning motor speech plans and the trajectory of motor speech recovery.
Time frame: 6 months
