Brief summary

The investigators aim at testing the efficacy of an app to measure sentence intelligibility in noise in speakers with Parkinson's disease and in healthy controls.

Detailed description

Close to 90% of people with Parkinson's disease develop voice problems during the course of the disease. These problems lead to reduced intelligibility, which entails a subsequent reduction in social participation and overall quality of life. The current study will focus on developing and pilot-testing an app to measure the intelligibility of people with PD and of healthy controls. In order to test the app's efficacy, speakers will read a set of 50 sentences that will be embedded in noise for measurement purposes. A group of listeners will also transcribe the spoken sentences to correlate their performance to that of the app. The ultimate purpose of this investigation is to improve self-monitoring and self-sufficiency in people with PD. The study is expected to last 12 months.
