Speech & Voice Therapy

Have you noticed changes to your voice involving loudness, quality, pitch, or resonance? Or have you experienced changes in your speech, making it difficult for others to understand you?

Speech changes can result from a variety of diagnoses, such as Parkinson’s disease, stroke, traumatic brain injury, and other degenerative neurological disorders.

Speech disorders can present as dysarthria, a condition in which the muscles of the mouth, face, voice, and respiratory system may be weak or move slowly.

Speech disorders can present as apraxia, caused by injury to the parts of the brain associated with speech, resulting in inconsistent speech errors.


Causes of voice disorders can include damage to the vocal cords, respiratory disorders, vocal tension, neurological disorders, gastroesophageal reflux (GERD), and aging.

Here are common symptoms associated with speech and voice disorders:

One of the most common diseases that Speech Therapists address is Parkinson’s disease, which can affect speech and voice. Research shows that 89% of people diagnosed with Parkinson’s disease (PD) experience speech and voice disorders.

As a result of these symptoms, individuals with Parkinson’s disease report being less likely to participate in conversations or have confidence in social settings compared to healthy individuals in their age group.
