Our voice team also is trained in SPEAK OUT! and Loud Crowd!

See below for details!

What are the SPEAK OUT! and LOUD Crowd therapies?

SPEAK OUT! is a therapy regimen tailored to people with Parkinson’s disease to improve their voicing, and in turn, their swallowing. In this program, speech is transformed from an automatic function to an intentional task. SPEAK OUT! is usually completed in 12 sessions spanning four weeks, and then the client transitions to the LOUD Crowd. In this four-week span, clients report improvement in their speaking, their ability to be heard, and their overall quality of life.

LOUD Crowd is the group therapy portion of the program and meets once weekly. The sessions provide maintenance for skills obtained during SPEAK OUT! and are a source of camaraderie for the members. Speech Associates offers LOUD Crowd for free to SPEAK OUT! graduates.
