About this study
Official title: Randomized Trial of AI-Enhanced Maintenance Training With Visual-Acoustic Biofeedback
Speech Sound Disorder (SSD) affects a significant portion of school-aged children, leading to social and emotional challenges that can persist into adolescence and adulthood. The number of productions necessary for a remediated speech sound to generalize to connected speech is challenging to achieve in practice, leading clinicians to call for accessible, reliable resources allowing children to continue therapy outside of direct clinical interactions. Artificial intelligence (AI) tools hold promise as a means to extend direct service delivery in speech-language pathology, but research investigating the topic has been limited. This study (Generalization with AI Navigation using staRt, or GAINS) will measure the effects of a course of AI-mediated home practice intended to promote generalization of gains made through biofeedback treatment in a related study, Visual-acoustic Intervention with Service Delivery In-person and Via Telepractice Trial (VISIT; NCT06517225).
Read the detailed description
This study will measure the effects of AI-guided home practice as a follow-up to participation in a study of technology-enhanced treatment for speech sound disorder affecting the American English "r" sound. Participants will sign a single consent form that covers their participation in the original VISIT study (in which they are randomized to receive biofeedback treatment in person or via telepractice) and and the follow-up GAINS study (in which participants are randomized to a follow-up period of treatment as usual [TAU] or treatment as usual plus an AI-guided maintenance program with biofeedback [TAU+AI]).We will measure production accuracy at the start and end of GAINS to test our working hypothesis that children/adolescents with speech sound disorder will show higher accuracy in /r/ production after six weeks of TAU+AI than six weeks of TAU alone. All GAINS treatment sessions will be carried out in the home setting using online tools. Pre and post treatment evaluations will be carried out in the laboratory setting.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AI-guided maintenance training with visual-acoustic biofeedbackBehavioural
Participants will complete AI-guided practice in the home setting in which they will interact with a web interface of the staRt web-based software for speech practice. The staRt software will present words to practice and show a real-time visual display of the acoustic signal of speech (biofeedback). On select trials, feedback will be provided by a classifier for children's "r" sounds, PERCEPT. Research assistants will join sessions to facilitate but will not provide direct clinical guidance to participants.
Treatment as Usual (TAU)Behavioural
Participants will return to their regular community-based care. This may consist of treatment in the school setting or by a private SLP; participants who were not previously receiving treatment may return to a no-treatment condition. Data will be collected from parents/guardians to determine the frequency of treatment, if any, received during this phase.
| Study group | Role | What they receive |
|---|---|---|
| AI-guided maintenance training with visual-acoustic biofeedback | Experimental | Participants will receive visual-acoustic biofeedback treatment from a clinician in a private, password-protected WebRTC room. Receives: Behavioral: AI-guided maintenance training with visual-acoustic biofeedback; Behavioral: Treatment as Usual (TAU) |
| Treatment as usual [TAU] | Active comparator | Regular community-based care. Receives: Behavioral: Treatment as Usual (TAU) |
What is being measured
The primary outcome is the main question the study is designed to answer.
1. Percentage of "Correct" Ratings by Blinded Untrained Listeners for /r/ Sounds Produced in Word Probes
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. We will use the proportion of "correct" ratings for each token as our primary measure of perceptually rated accuracy.
Measured: Immediately before the initiation of GAINS participation and again after the end of GAINS participation (6 weeks later)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing AI-guided maintenance training with visual-acoustic biofeedback and Treatment as Usual (TAU) in people with Speech Sound Disorder, run by New York University at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Tara McAllister, PhD (212-992-9445, tkm214@nyu.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
1. Percentage of "Correct" Ratings by Blinded Untrained Listeners for /r/ Sounds Produced in Word Probes (time frame: Immediately before the initiation of GAINS participation and again after the end of GAINS participation (6 weeks later)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06884943, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 May 2026.
