The main questions it aims to answer are: * Primary hypothesis: Biofeedback treatment for sibilants delivered via telepractice will produce positive gains compared to a no-treatment baseline phase. * Secondary hypothesis: Participants will experience positive changes in social-emotional well-being after receiving biofeedback treatment for sibilants as reported by the participants and their guardians. Following the initial evaluation, participants will be randomly assigned to transition from baseline to treatment at one of seven possible points, ranging from 4-10 baseline sessions in which /s/ production will be probed but not treated. All participants will then receive 20, 1-hour biofeedback treatment sessions over 10 weeks with a certified Speech-Language Pathologist via teletherapy, followed by three maintenance sessions.
