الملخص: In this work, we studied the possibility of the detection of Parkinson disease from the voice signal variation patterns. We further developed a model using the voice signal features and evaluated its effectiveness. From the experimental results, we conclude that the recognition rate of KNN comes out to be 80%, but, with Naïve Bayes the classification has the highest recognition rate which is 93.3%. So we can say that it is better for recognition. The developed system was confirmed that voice signal measurement is a practical and useful screening test to estimate whether patients have PD or not
