LSVT LOUD vs SPEAK OUT! - Which voice treatment is best for Parkinson's?

Parkinson's affects  nearly one million people in the United States.

One of the early signs of Parkinson's is a change in voice.  The voice may become soft or hoarse.  It's a common symptom early in the disease and worsens as the disease progresses.  A soft voice can make it difficult to do common daily activities like have a conversation, give a presentation, or order a cup of coffee.  

Speech Therapy can help improve the strength, loudness, and clarity of your voice.  


Two speech therapy programs are well-researched for Parkinson's Disease:  Lee-Silverman Voice Treatment (LSVT-LOUD) and SPEAK OUT! from Parkinson Voice Project. 

SPEAK OUT! voice therapy for Parkinson's. In-home treatment available with Speech Spark in Green Bay, Wisconsin and the surrounding area.

SPEAK OUT! voice therapy for Parkinson's. In-home treatment available with Speech Spark in Green Bay, Wisconsin and the surrounding area.

SPEAK OUT! focuses on the concept of intent.  SPEAK OUT! strengthens the muscles used for speaking and swallowing and places emphasis on speaking with intent and converting speech from an automatic function to an intentional act.  In therapy, we work through a series of speech, voice, and cognitive exercises outlined in the free SPEAK OUT! Workbook.  

LSVT LOUD focuses on the concept of sensory re-calibration and using a loud voice. Because it takes more effort to use a strong clear voice, a person with Parkinson's often feels that they are shouting if they are using a "normal" loudness.  

LSVT-LOUD is more well-known.  45 minute SPEAK OUT! sessions at three times a week may be easier for a person to fit into their schedule than 60 minute sessions 4 times a week that LSVT LOUD requires.
