Details and patient eligibility

About

The aim of this research is to develop protocols that selectively target and improve speech-motor learning processes. Participants will be asked to name pictures, read words/sentences, and listen to sounds while their speech signals will be collected during the study.

Enrollment: 510 estimated patients
