For tests, the team interviewed and recorded 129 war-zone exposed veterans and collected 40,000 speech samples to study. They then used the audio to teach the AI with vocal changes associated with diagnoses of PTSD, for instance, a slower and dull tone was an indicator of PTSD, as well as a shorter tonal range with less enthusiasm.

AI can detect slight changes in the voice such as the tension of throat muscles and whether the tongue touches the lips all probable indicators of a PTSD diagnosis.
