Voice Classes


Voice classes are provided through the Muhammad Ali Parkinson Center Outreach Program that focus on improving your voice quality, loudness, and speech clarity.  

All classes are taught by a Speech-Language Pathologist trained in SPEAK OUT!® and Lee Silverman Voice Therapy (LSVT®). 

Class Eligibility Criteria

Our 1:00 PM Tuesday class is open to all people whether or not you have recently completed skilled speech therapy services.

Wednesday and Thursday at 1:00 PM is The LOUD Crowd® class. People who have recently completed the SPEAK OUT® program are eligible to attend LOUD Crowd®. SPEAK OUT!® is a speech therapy program tailored to people with Parkinson’s disease to improve their voice and speech.
