Visual-acoustic Intervention With Service Delivery In-person and Via Telepractice Trial

Children with speech sound disorder show diminished intelligibility in spoken communication and may thus be perceived as less capable than peers, with negative consequences for both socioemotional and socioeconomic outcomes. New technologies have the potential to transform interventions for speech sound disorder, but there is a lack of rigorous evidence to substantiate this promise. This research will meet a public health need by systematically evaluating the efficacy of visual-acoustic biofeedback intervention delivered in-person versus via telepractice. The objective of this study is to test the hypothesis that treatment incorporating visual-acoustic biofeedback can be delivered via telepractice without a significant loss of efficacy. Participants will be randomly assigned to receive identical treatment either via online telepractice or in the laboratory setting. The same software for visual-acoustic biofeedback, staRt, will be used in both conditions. Participants' progress in treatment will be evaluated based on blinded listeners' perceptual ratings of probes produced before and after treatment. Pre and post treatment evaluations will be carried out in person for all participants.
