Using voice recordings and smartphone movements you can make a Parkinson's diagnosis. Diagnosing Parkinson's Disease can be a long and difficult process as there is no blood test for it and it often involves multiple visits with a neurologist. The Parkinson's Voice Initiative is working on finding a less expensive and more accessible way to use people's voice patterns.
Beyond trembling limbs and a stopped gait, Parkinson's Disease symptoms include breathiness and specific fluctuations of the voice. Led by Max Little, this Parkinson's diagnosis project is looking to create a method to test these voice patterns, using a smartphone for instance. The British mathematician and visiting professor at MIT is currently analyzing recordings, after which he will be able to develop a system that automatically analyzes voices.
