Dr. James Mahshie is a Professor in the Department of Speech and Hearing Sciences at the George Washington University. His expertise lies in the areas of deafness, aerodynamic studies of voice and speech production and acoustic analysis of speech. Dr. Mahshie is also the Principle Investigator of “Speech Production and Perception Skills of Children Using Cochlear Implants: Implications for Implant Fitting and Habilitation.” His current research involves exploration of various aspects of speech production and perception by deaf and hard of hearing individuals. His research includes studies aimed at
- Improved understanding of the physiological underpinnings of speech production by those with hearing loss, and
- Development and assessment of various computer-mediated approaches to improving speech production by deaf individuals, and
- Study of the relation between perceptual capacity for certain speech features, and the ability to use these features in speech production.
