  • Aerodynamic studies of voice and speech production
  • Acoustic analysis of speech

Background

James Mahshie is involved with research and clinical work focusing on enhancing the communication skills of children who are deaf or hard of hearing. He is a professor and Department chair at The George Washington University in Washington, DC, USA. He has taught numerous courses dealing with speech and language abilities of children with hearing loss as well as approaches to aural (re)habilitation with children and adults.  He directs the Cochlear Implant Communication Lab where his currently funded research explores the development of speech perception and production abilities by children with cochlear implants. Prior to his arrival at George Washington he was a faculty member at Gallaudet University where he was chair of the Department of Speech, Language, and Hearing Science.  His professional life has been committed to better understanding how deaf and hard of hearing children and adults communicate through spoken language and the development of improved strategies to enhance communication. He has written numerous articles, book chapters, and a book on these topics. He is a fellow of the American Speech-Language-Hearing Association.

Current Research

  • Dr. Mahshie’s 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
  • Additional research has recently focused on examining how well deaf 
individuals understand the intelligibility of their own speech production, and the use of speech modeling to better understand both normal and 
abnormal speech.
