AbstractA study was conducted to assess the relationship between facial motion and acoustics in patients suffering from Parkinson's Disease (PD). The study used 3D motion data with time-aligned acoustics acquired from the participants to conduct the investigations. It was assumed that the relationship between facial motion and acoustics in PD was lower in comparison of age-matched healthy speakers with that of young healthy speakers. The results were expected to have implications for potential development of facial motion based speech recognition software in addition to providing theoretical knowledge about the audio-visual relationship in speech of these populations.
