Diagnosis of Parkinson's Disease in Human Using Voice Signals

Hamid Karimi Rouzbahani, Mohammad Reza Daliri
2011 Basic and Clinical Neuroscience  
A total of 31 people with and without the disease participated in the data collection phase. Their voice signals were recorded and processed. The relevant features were then extracted.  ...  A full investigation into the features extracted from voice signals of people with and without Parkinson's disease was performed.  ...  This was done by the investigation of maximum extent of amplitude sequence in each cycle. The difference appears, when averaging mentioned sequences, and this difference is used as a measure.  ...
