Almost 90% of individuals with Parkinson's disease will have speech and voice disorders at some time during the course of the disease. The most common problems are reduced speech volume, speaking in a monotone, a breathy or hoarse sounding voice, and imprecise articulation. These are all due to problems with the oral muscles, similar to the muscle problems experienced throughout the body for those with Parkinson's disease.

It is best to start speech and voice training in the early stages of Parkinson's disease to minimize the associated communication problems. At BAPTIST HEALTH Rehabilitation Institute, the Speech-Language Pathologists have the specialized training and experience to assist those who require speech and voice training with specific exercises, communication technologies, and other vocal strategies.
