CI Communication Lab

The Cochlear Implant Communication Lab is located on GWUs Foggy Bottom campus.  The Lab addresses a range of projects that examine the spoken language production and perception development, and abilities of deaf children with cochlear implants (CI). 

Among the projects underway are studies of:

  • How CI children develop perception and production of speech features,
  • CI children's speech articulation characteristics as they relate to language development,
  • Voice quality characteristics and their contribution to speech intelligibility in CI children, and
  • Prosody characteristics and development of children with CIs.

Current projects are receiving support from the following agencies:

"Prosody and Voice Characteristics of Children with Cochlear Implants"

  • The goal of this project is to investigate the prosody and voice quality characteristics of children with cochlear implants.  Funded by NIDRR - field initiated grant.
  • H133GI20272, Mahshie, PI, 10/12 - 09/2015

"Speech Perception and Production Skills in Children Using Cochlear Implants"

  • The goal of this study is to investigate the relationship between perception and production of phonetic features in young deaf children who use cochlear implants.  Funded by NIDRR, Rehabilitation Engineering and Research Center at Gallaudet University
  • H133E080006, Mahshie, PI, Core, C., Co-PI, 10/2009 - 09/2014
  • If your child has normal hearing and you would like them to participate in the study, more information can be located here
  • If your child has a cochlear implant or uses hearing aids and you would like them to participate in the study, more information can be located here
