Trial Summary
What is the purpose of this 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.
Do I need to stop my current medications to join the trial?The trial protocol does not specify whether you need to stop taking your current medications. It seems unlikely that you would need to stop, as the focus is on speech sound disorder and not on medication use.
Is the treatment Visual-acoustic biofeedback promising for speech sound disorders?Yes, Visual-acoustic biofeedback is promising for speech sound disorders. It helps people see and correct their tongue movements, which can improve speech, especially for those who find it hard to hear or describe sounds. Studies show it can be effective for children and adults with persistent speech issues.12567
What safety data exists for visual-acoustic biofeedback therapy for speech disorders?The available research does not explicitly mention safety data or undesired effects for visual-acoustic biofeedback therapy. However, the studies suggest that ultrasound visual feedback is a non-invasive tool used in speech therapy, and no specific safety concerns are reported in the abstracts provided.12367
What data supports the idea that Visual-Acoustic Biofeedback for Speech Sound Disorder is an effective treatment?The available research shows that Visual-Acoustic Biofeedback, particularly using ultrasound, is effective for treating speech sound disorders. For example, a study involving children with persistent speech sound disorders found that all participants made significant progress in their speech after using ultrasound biofeedback. Another study showed that children with various speech sound disorders quickly learned new speech movements using ultrasound biofeedback, even when they couldn't do so before the treatment. These studies suggest that this method can be a valuable addition to traditional speech therapy, especially for those who have not responded well to other treatments.12467
Eligibility Criteria
This trial is for children with speech sound disorder, which affects their clarity of speech. The study aims to help these children improve their spoken communication through a special treatment using visual-acoustic biofeedback.Inclusion Criteria
I have a laptop or desktop computer for study sessions.
My mouth and its functions have been checked and are okay.
I am between 9 years and 17 years, 11 months old.
I speak English as my main or one of my main languages.
Exclusion Criteria
I have not had an epileptic seizure in the last 6 months.
I do not have noticeable speech difficulties.
I do not have non-removable braces that cross my palate.
I have not had a major brain injury, surgery, or stroke in the last year.
I have never had permanent hearing loss.
Treatment Details
The trial is testing if visual-acoustic biofeedback therapy for speech sound disorder can be just as effective when given online (telepractice) as it is in person. Children will use the staRt software and their progress will be measured by how well they speak before and after the treatment.

Ultrasound biofeedback for speech training. Instrumentation and preliminary results. [2019]Real-time ultrasound scanning was employed as biofeedback therapy to correct a persistent articulatory speech defect in a subject. The subject continuously imaged her tongue with a transducer placed submentally. During a speech exercise, the subject could compare her tongue's positioning and movement with an ultrasound image showing the correct tongue placement prerecorded onto video tape by a speech therapist. Preliminary results suggest that this technique could be a valuable addition to speech therapy.
Using ultrasound visual biofeedback to treat persistent primary speech sound disorders. [2022]Growing evidence suggests that speech intervention using visual biofeedback may benefit people for whom visual skills are stronger than auditory skills (for example, the hearing-impaired population), especially when the target articulation is hard to describe or see. Diagnostic ultrasound can be used to image the tongue and has recently become more compact and affordable leading to renewed interest in it as a practical, non-invasive visual biofeedback tool. In this study, we evaluate its effectiveness in treating children with persistent speech sound disorders that have been unresponsive to traditional therapy approaches. A case series of seven different children (aged 6-11) with persistent speech sound disorders were evaluated. For each child, high-speed ultrasound (121 fps), audio and lip video recordings were made while probing each child's specific errors at five different time points (before, during and after intervention). After intervention, all the children made significant progress on targeted segments, evidenced by both perceptual measures and changes in tongue-shape.
Do Participants Report Any Undesired Effects in Ultrasound Speech Therapy? [2023]Ultrasound visual feedback of the tongue is increasingly used as a component of speech therapy in clinical research and practice. The purpose is to offer a preliminary summary of the nature of participant-reported undesired effects related to ultrasound visual feedback.
Enabling New Articulatory Gestures in Children With Persistent Speech Sound Disorders Using Ultrasound Visual Biofeedback. [2021]Purpose This study evaluated ultrasound visual biofeedback treatment for teaching new articulations to children with a wide variety of speech sound disorders. It was hypothesized that motor-based intervention incorporating ultrasound would lead to rapid acquisition of a range of target lingual gestures with generalization to untreated words. Method Twenty children aged 6-15 years with a range of mild to severe speech disorders affecting a variety of lingual targets enrolled in a case series with replication. Of these, 15 children completed the intervention. All of the children presented with a variety of errors. We therefore employed a target selection strategy to treat the most frequent lingual error. These individual speech targets were treated using ultrasound visual biofeedback as part of ten to twelve 1-hr intervention sessions. The primary outcome measure was percentage of target segments correct in untreated wordlists. Results Six children were treated for velar fronting; 3 children, for postalveolar fronting; 2 children, for backing alveolars to pharyngeal or glottal place; 1 child, for debuccalization (production of all onsets as [h]); 1 child, for vowel merger; and 2 children, for lateralized sibilants. Ten achieved the new articulation in the 1st or 2nd session of intervention, despite no children being readily stimulable for their target articulation before intervention. In terms of generalization, effect sizes for percentage of target segments correct ranged from no effect (5 children), small effect (1 child), medium effect (4 children), and large effect (5 children). Conclusions Ultrasound visual biofeedback can be used to treat a wide range of lingual errors in children with various speech sound disorders, from mild to severe. Visual feedback may be useful for establishing new articulations; however, generalization is more variable.
Effectiveness of an Ultrasound Visual Biofeedback Training for Tongue Shape Assessment During Speech Sound Production. [2022]This proof-of-concept study examined the effectiveness of an ultrasound visual biofeedback (UVB) training within the Participatory Adult Teaching Strategy framework for instructing speech-language pathologists (SLPs) on the assessment of sonographic tongue configuration for remediation of speech sound errors.
Protocol for SonoSpeech Cleft Pilot: a mixed-methods pilot randomized control trial of ultrasound visual biofeedback versus standard intervention for children with cleft lip and palate. [2022]Children with cleft lip and palate can continue to have problems producing clear speech after surgery. This can lead to social, emotional, and educational challenges. Typical treatment involves teaching children the correct tongue movements to produce speech sounds. This is known as articulation intervention. However, this intervention is challenging because the tongue is hidden from view and movements are difficult to see and describe. This pilot randomized control trial will try a new treatment, ultrasound visual biofeedback (U-VBF) versus standard articulatory intervention for children with cleft lip and palate, as comparison. Feasibility outcomes will be determined.
