Summary

This study tests whether analyzing a person's voice can help predict upcoming depressive or manic episodes in bipolar disorder. Researchers will collect voice recordings and lifestyle data from 170 adults with bipolar disorder over 6 months. The goal is to build a model that spots early warning signs of relapse, which could lead to faster treatment and better management of the condition.
