LSVT LOUD is an effective speech treatment for people with Parkinson’s disease (PD) and other neurological conditions. LSVT LOUD trains people with PD to improve their speaking volume to achieve an average level of loudness while speaking at home, at work, or in the community. It is essential for patients with PD to learn how to recalibrate their perceptions to understand how loud or soft they sound to other people. This will help them feel comfortable using a stronger voice at a normal loudness level.
