Objective Assessment of Post-Traumatic Stress Disorder Using Speech Analysis in Telepsychiatry

Abstract

The objective of this project is to explore the feasibility of using speech features to assess the Post-Traumatic Stress Disorder (PTSD) status of a patient. The premise for this project is that an individual's speech features, drawn from a recorded CAPS interview, correlate to the diagnosis of PTSD for that person. Recorded interviews from a patient population will be used to develop and test an objective scoring system. NYU is collecting speech data from patients and supplying it to SRI International. SRI now has data from 20 PTSD-negative patients and 13 PTSD-positive patients. Few PTSD-positive patients meet the inclusion criteria for the study so it is taking much longer than expected to acquire the target of 20 PTSD-positive samples. Preliminary tests using this small dataset show promise in predicting PTSD based on speech characteristics.
