We apply linear regression and other non-linear methods such as Gaussian process regression and support vector regression. These models are trained on a dataset with known perceptual ratings, and thereafter used for prediction. The prediction performance is evaluated using various metrics such as mean-square error and Pearson's correlation coefficient. In this document we study the performance of our system in the intelligibility prediction experiment using a database of 160 sentences collected from 48 Parkinson's patients. The results of intelligibility prediction are encouraging, for example, the correlation between perceptual scores and computed scores is high (>0.9) showing excellent agreement.
