Visuel-akustisk indgriben med servicelevering personligt og via telepraksisforsøg (VISIT)

2. november 2026 opdateret af: New York University

Visuel-akustisk intervention med servicelevering personligt og via telepraksis (VISIT) Non-inferiority-prøve

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.

Detaljeret beskrivelse

This study aims to test the working hypothesis that biofeedback treatment delivery via telepractice will not be associated with a reduction in efficacy that exceeds a maximum acceptable value determined a priori. In a prospective randomized controlled non-inferiority trial, children will be randomly assigned to receive a standard course of visual-acoustic biofeedback intervention delivered in-person or via telepractice. Progress will be measured with blinded listeners' ratings of untreated words produced before and after treatment. A survey will also be administered before and after treatment to assess changes in participants' participation and socio-emotional well-being, as well as participants' and caregivers' satisfaction with the therapy experience.

Eksperimentel: Telepractice delivery

Participants will receive visual-acoustic biofeedback treatment from a clinician in a private, password-protected WebRTC room.
Adfærdsmæssigt: Visual-acoustic biofeedback

Behavioral: Visual-acoustic biofeedback In visual-acoustic biofeedback treatment, the elements of traditional treatment (auditory models and verbal descriptions of articulator placement) are enhanced with a dynamic display of the speech signal in the form of the real-time LPC (Linear Predictive Coding) spectrum. The web-based software staRt will be used for intervention delivery.

Tidsramme
Percentage of "Correct" Ratings by Blinded Untrained Listeners for /r/ Sounds Produced in Word Probes
Tidsramme: Before the initiation of treatment and again after the end of all treatment (10 weeks later)

To assess generalization of treatment gains to untreated words, participants will be assessed with standard probes (30 words [considered the primary target], 20 syllables, and 10 sentences containing /r/ in various phonetic contexts). Stimuli in each probe will be presented individually in randomized order with blocking by stimulus type (word, syllable, sentence). Individual words will be isolated from the audio record of each word probe and presented in randomized order for binary rating (correct/incorrect) by 9 untrained listeners who are blind to treatment condition and time point, but will see the written representation of each target word. The proportion of "correct" ratings for each token will be used as the primary measure of perceptually rated accuracy.

Tidsramme
1. Survey evaluating impacts of speech disorder on participants' social, emotional, and academic well-being.
Tidsramme: Before the initiation of treatment and again after the end of all treatment (10 weeks later)

This survey asks participants to report the impact of speech disorder on their child's social, emotional, and academic well-being. Parents are asked to circle a number from 1 to 5. For all questions, a higher score indicates a greater degree of negative impact of speech disorder on social, emotional, or academic well-being. An impact score will be calculated as described in a previous published study (Hitchcock, Harel, & McAllister Byun, 2015).
