The Optispeech system has been used to deliver visual feedback for tongue positioning in children with disordered speech due to dysarthria (including cerebral palsy), persistent speech errors, and hearing impairment. Studies have also examined adults with dysarthria, and we are currently investigating individuals with Apraxia of Speech (AOS).
