Use of Conversation and Acoustic Signals in Measuring Depression Severity
NCT00831935 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to test a new monitoring technology that uses the sound of a depressed person's speech to assess the severity of depression symptoms. The Vocal Social Signals Platform (VSSP) is software that analyzes the non-verbal characteristics of a person's speech. This study will test this software to see if it could be a useful measurement tool for assessing depression symptoms. Participation in this study requires coming to the research headquarters twice over a three-month period. The first visit is to determine eligibility. Throughout the study, participants will be connected to a telephone system five times, on which they will answer questions about their depression symptoms. After answering questions, their voice will be recorded using a structured speech sample that the participant will read out loud. The participant will also give an unstructured speech sample, which will involve describing a typical day or the last movie s/he saw. The voice samples will be analyzed and compared to the results of the depression symptom questionnaires.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00831935
The ClinicalTrials.gov registry entry for NCT00831935 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 89 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Boston Medical Center, which has 192 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 Depression appearing as the primary indexed condition, and to 0 interventions. 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: NCT00831935 reports 2 study locations spanning 1 distinct geographic area — top geographies include Massachusetts. 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.
