Summary

This study looks at how deep brain stimulation (DBS) for Parkinson's disease affects speech. Researchers will record voices of 60 participants before and after surgery to measure changes in clarity, emotion, and word choice. The goal is to better understand the benefits and risks of DBS on communication.
