PTSD therapy gets a voice twist: study tests emotional tone shifting
NCT ID NCT06129981
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if a voice-changing device could make exposure therapy easier for people with PTSD. Patients would read their trauma story aloud while software altered their voice's emotional tone, hoping to reduce distress. The study was withdrawn before any participants were enrolled, so no results are available.
