Who founded the Parkinson Voice Project?

The Parkinson Voice Project was founded by a speech-language pathologist, which is why this answer is correct. This choice highlights the emphasis on communication and voice therapy, which are vital areas of focus in the treatment of individuals with Parkinson’s disease. The work of a speech-language pathologist involves assessing and treating speech disorders, making their expertise particularly relevant in addressing the speech challenges faced by people with Parkinson's.

A medical doctor, neurologist, and psychologist, while they may contribute significantly in their respective fields regarding the treatment of Parkinson's disease, are not primarily focused on the specific voice and speech issues that the Parkinson Voice Project aims to address. Thus, the founding by a speech-language pathologist is significant as it underscores the project's dedication to enhancing the quality of life for those dealing with the speech impairments associated with the disease.
