RT Conference Proceedings T1 Random forest-based prediction of Parkinson's disease progression using acoustic, ASR and intelligibility features A1 Zlotnik, Alexander A1 Montero Martínez, Juan Manuel A1 San Segundo Hernández, Rubén A1 Gallardo Antolín, Ascensión AB The Interspeech ComParE 2015 PC Sub-Challenge consists of automatically determining the degree of Parkinson's condition using exclusively the patient's voice. In this paper, we face this problem as a regression task and in order to succeed, we propose the use of an ensemble learning method, Random Forest (RF), in combination with features of different nature: acoustic characteristics, features derived from the output of an Automatic Speech Recognition system (ASR) and non-intrusive intelligibility measures. The system outperforms the baseline results achieving a relative improvement higher than 19% in the development set.
