According to the World Health Organization, more than 264 million people worldwide have major depression disorder and another 20 million have schizophrenia.
MDD and schizophrenia are one of the most common precursors of suicide and, according to a 2018 CDC report, suicide is the second leading cause of death in young people and young adults between the ages of 10 and 34, the second leading cause of death in black children aged 10 to 14 years, and the third leading cause of death in black adolescents aged 15 to 19 years.
During the 180th Meeting of the Acoustic Society of America, to be held from June 8-10, Carol Espy-Wilson, of the University of Maryland, will discuss how a person’s mental health is reflected in the coordination of speech gestures. The main conference, “Speech Acoustics and Mental Health Assessment,” will take place on Tuesday, June 8th.
A speech inversion system assigns acoustic signals to vocal track variables, showing the time and spatial movement of speech gestures. Espy-Wilson said speech coordination changes when a person becomes depressed.
“Depression is accompanied by a psychomotor slowdown. As a result, they can’t think so fast and their speech frequency is reduced with longer and longer pauses than if they weren’t depressed,” Espy-Wilson said. “This translates into easier coordination of the articulators. What this means is that there is less co-production of neighboring sounds and that more of the sounds are fully articulated, meaning that the articulators achieve their goals.”
The use of machine learning techniques can help provide data for a deep learning model for mental health classification. The aim of the research is to use technology, perhaps in the form of a smartphone app, to help patients and those around them stay informed about their mindset. Health, which Espy-Wilson said would have a big impact.
“Ideally, therapists would give the application to patients who suffer from MDD when they are in remission or have only mild depressionThat is, they are in a state where they are likely to use it regularly, so theirs mental health the condition can be monitored and the right people will be notified if the app detects that the severity of the depression is increasing.
“That way, we expect there to be intervention before their depression rises to a level where they can consider suicide.”
