How does Parkinson’s Disease affect speech? 💬
Up to 90% of people with Parkinson’s experience changes in their voice and speech. This includes:
- Soft or breathy voice
- Monotone or low-pitched voice
- Slurred or mumbled words
- Speaking too quickly or slowly
- Difficulty with volume control
These changes are due to decreased coordination and strength of the muscles involved in speech.
Speech therapy, particularly programs like LSVT LOUD, can significantly improve clarity, loudness, and confidence in communication.
