Abstract
Dysarthria is one of the typical early symptoms of Parkinson's Disease (PD), and that is the basis of diagnosing PD with the speech signal. In this paper, we propose a novel method to analyse the speech signal by Convolutional Neural Network (CNN). At first, the time series signal of speech is converted into spectrograms to represent the time and frequency features in a signal figure; and then, we train the CNN with the spectrograms and their labels from the training set. At last, we test the network precision by the test set of speech signals. The experiments show the accuracy of the method is 91%, which is outperforming the traditional classification for speech signals.
