PTSD can be diagnosed using AI, which analyzes Voice

Post-traumatic stress disorder is difficult to diagnose, but now the AI ​​tool can help diagnose, according to new research.

Typically, PTSD is diagnosed through clinical interviews or self-reporting, but these methods are extremely vulnerable to over-reporting or inadequate reporting. On the other hand, scientists say that AI can take post-traumatic stress disorder from the individual's speech patterns with 89% accuracy.

In the diary Depression and anxietyResearchers share how the use of AI can change the field and provide a more accurate technique to diagnose PTSD.

The study revealed AI, which detected PTSD

For the study, the researchers collected speeches from veterans exposed to military zones. According to a report from New York University at Langone Health, 53 of the samples were from individuals diagnosed with PTSD using the PTSD scale administered by the clinician while 78 served as a control.

These voice recordings are put into voice software by SRI International, which gives the researchers 40,526 different speech functions. The AI ​​program for team accidental forest activities continued to analyze these thousands of speech features for PTSD compliant models.

The program associates certain models of voice with PTSD, including features compatible with anecdotal diagnostic reports.

"Those with the PTSD spoke more slowly (a slower movement of the tongue), they were more monotonous with fewer bursts of vocalisation, less animated and energetic in their speech, and had longer fluctuations and smoother tones "The study author and chair of psychiatry at the University of Medicine at New York University said in a report by Reuters.

Marmar adds that team findings can lead to the use of speech features in clinical situations in the future.

Move forward with AI-based diagnostics

According to the National Center for Post-Traumatic Stress Disorder, 7 to 8 percent of the adult population in the United States is experiencing PSTD at some point in its life. In a given year, 8 million adults have PTSD.

This new tool can help diagnose these people.

Researchers have revealed that future efforts include training the AI ​​tool with more data and validating findings with an independent sample. Eventually, they hope to get approval from the government to use it for the clinical diagnosis of PTSD.

"Speech is an attractive candidate for use in an automated diagnostic system, perhaps as part of a future PTSD smartphone application, as it can be measured inexpensively, remotely and unobtrusively," Adam Brown, lead author and assistant professor at the Department of Psychiatry at the New York University Medical School says.
