Parkinson's disease (PD) is a neurodegenerative disorder that affects the coordination of muscles and limbs, including those responsible of the speech production. The lack of control of the limbs and muscles involved in the speech production process can generate intelligibility problems and this situation has a negative impact in the social interaction of the patients. Due to this, it is required the development of flexible tools able to asses and guide the speech therapy of the patients. In this article, the design and deployment of a new device for the real time assessment of speech signals of people with PD is presented. The processes of design and deployment include the development on three platforms: first, a graphic user interface is developed on Matlab, second the first prototype is implemented on a digital signal processor and third, the final device is developed on a mini-computer. The device is equipped with an audio codec, storage capacity and the processing unit.
