Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
