Managing Vocal Changes with PD

Voice Changes in Parkinson’s Disease: How an SLP Can Help

When most people think of Parkinson’s disease, they picture tremors or movement difficulties. But did you know that Parkinson’s often affects the voice too? These changes can make communication harder and impact confidence—but help is available.

Why Does Parkinson’s Affect the Voice?

Parkinson’s disease impacts the nervous system, which controls muscle movement—including the muscles used for speech. Over time, this can lead to:

• Reduced vocal loudness (your voice sounds softer)

• Monotone speech (less pitch variation)

• Hoarseness or breathiness

• Slurred or unclear articulation

• Difficulty starting speech or maintaining flow

These changes happen because the muscles of the larynx, respiratory system, and articulators become less coordinated and weaker.

Why Voice Changes Matter

A softer, less expressive voice can make conversations frustrating. People may ask you to repeat yourself, or you might avoid speaking altogether. This can lead to social isolation and reduced quality of life—but it doesn’t have to.

How Can a Speech-Language Pathologist Help?

SLPs specialize in communication and swallowing disorders, and they play a vital role in Parkinson’s care. Here’s what we do:

• Comprehensive Voice Assessment
  We evaluate loudness, pitch, clarity, and breathing patterns to understand your unique challenges.
  
  

• Evidence-Based Therapy
  Programs like Lee Silverman Voice Treatment focus on increasing vocal loudness and clarity through structured exercises.
  
  

• Breathing and Posture Techniques
  Improving breath support helps sustain speech and volume.
  
  

• Articulation and Intonation Training
  We work on speech clarity and adding natural pitch variation to make communication easier.
  
  

• Home Practice Plans
  Daily exercises to maintain progress and keep muscles active.
  
  

Tips for Daily Life

• Speak slowly and clearly.

• Take a deep breath before starting to talk.

• Use short phrases and pause often.

• Practice speaking louder than you think you need—Parkinson’s often makes you feel louder than you really are.
