Official title

Development of a Convenient, Automated, Objective Measure of Depression

Brief summary

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

This Phase II SBIR study will replicate pilot study methods establishing computer-automated methods for assessing depression severity using interactive voice response system technology and demonstrating feasibility of obtaining measures of depression severity and treatment response through vocal acoustic analysis of speech samples obtained over the telephone. The study will automate vocal acoustic analysis methods, evaluate applicability to other patient populations (non-English speakers, children/young adult, and geriatric), and further develop multivariate acoustic models to enhance biomarker sensitivity to treatment response and prediction of the response likelihood for individual patients.
