Effects on Hearing Status on Adult Speech ProductionThe major goal of this project is to better understand the role that hearing plays in adult speech motor control by using a variety of listener groups, such as cochlear implant recipients, hearing aid users, persons who are pre-lingually deafened, elderly subjects, and normal-hearing young adults Constraints and Strategies in Speech ProductionThe project is investiagates motor control of speech with respect to its variability, efficiency, and communicative effectiveness. The research is designed to further develop and to test a theoretical framework that provides a synthesis of biomechanical constraints with economy of effort and perceptual strategies. Parkinson's Disease and Speech Production Part of this work is evaluating treatment effiacy of exercise and voice-based intervention via CSL MDVP. We are also looking at automatic recognition and landmark detection longitudinally to explore the potential of these methods for documenting improvement due to treatment.
