Project VOICES: Vocal Optimization in Children Elevating the Spectrum
NCT06875843 · View on ClinicalTrials.gov ↗
Study Summary
Thirty percent of children with autism barely talk or do not talk at all despite years of intervention. This study aims to address this important and long-standing challenge by developing a novel intervention to increase the quantity and quality of vocalizations (i.e., sounds children make before words) and expressive language in young children with autism (aged 2 to 5 years) with minimal verbal skills. The intervention includes contingent responses to the child's vocalizations and vocal elicitation strategies. We also collect social validity information from parents about how they perceive the novel intervention.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06875843
The ClinicalTrials.gov registry entry for NCT06875843 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 20 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Vanderbilt University Medical Center, which has 695 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Autism appearing as the primary indexed condition, and to 3 interventions — of which Non-contingent control is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06875843 reports 1 study location spanning 1 distinct geographic area — top geographies include Tennessee. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
