Voice-based Depression Study

Project Summary

Major Depressive Disorder (MDD) affects almost one in five women and one in twelve men in their lifetime and was recently recognized as the world's leading cause of disability. Yet current pharmacological and psychological therapies provide limited efficacy, and only about half of those suffering from MDD are identified and offered treatment. An obstacle preventing effective use of existing therapies, and impeding the discovery of better ones, is the difficulty of diagnosing MDD. Diagnosis is still made on the basis of a clinical interview and mental status examination, a method with relatively low reliability. Early intervention before the onset of severe symptoms can alleviate MDD's worst consequences including suicide. One possible source of information for improving diagnosis is the characterization of MDD from a person's speech.

Changes in the way people talk reflect alterations in mood, but attempts to use this information have not so far been clinically useful. Our work focuses on building algorithms to enable reliable automated detection of MDD from speech signals, with a special focus on voice quality features.

The major goals of this project are as follows. 

(1) To develop a diarization system to automatically annotate patient-doctor recordings.  

(2) To analyse voice samples of patients and model the relationship between speech acoustics and MDD.

(3) To develop classification systems that can predict MDD from voice samples.

(4) To study and improve the robustness of such classification systems to noise, language and other confounding variables.
