This study is for people with Parkinson's Disease (PD), a brain disorder that affects movement and speech. The researchers want to see if using noise-augmented feedback—a technique that uses sound to help with speech—can improve how well people with PD can speak and interact socially. Participants will do speech exercises at home using a phone and computer for four weeks. They will have some of their sessions watched online by a speech expert to ensure they are doing it right. The study will take about 7-8 months, including follow-up visits.

• Participation involves 16 home sessions and up to 7 lab visits over 7-8 months.
• Four of the speech sessions are monitored online by a professional.
• Eligible participants are aged 50-80 and have mild to moderate speech difficulties.

Participants need to be stable on their PD medication and should not have had recent voice treatments. The study takes place at Teachers College, Columbia University, and sessions last 60-90 minutes each.
