Areas of Expertise

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



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.
