Many children, adolescents, and adults struggle to eliminate speech errors affecting the American English 'r' sound. Research suggests that these errors can in some cases be eliminated through biofeedback, where learners view a dynamic visual image of their speech and attempt to match a target representing correct production. staRt ("Speech Therapist's App for /r/ Treatment") aims to make biofeedback treatment for /r/ widely accessible to practicing speech-language pathologists. Features: - Tutorial explaining how to interpret and use the biofeedback display - "Free play" mode where users match their real-time visual-acoustic display to a target representing correct production of ‘r’ - "Quest" mode presenting syllables/words for 'r' practice; complexity increases or decreases in an adaptive fashion based on recent performance - "Quiz" mode for use in measuring baseline performance and tracking progress - Visual rewards reinforcing improvements in performance - Clinician dashboard tracking progress over the course of treatment
