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 The study was withdrawn before any participants were enrolled, so no results are available.
