    Two communication systems using speech synthesis were developed for visually impaired individuals with physical handicaps. Both subjects learned to use the systems, though one faced challenges with sustained independent use.

    Area of Science:

    • Assistive Technology
    • Augmentative and Alternative Communication (AAC)
    • Biomedical Engineering

    Background:

    • Development of microcomputer-based communication systems for individuals with severe visual impairment and physical disabilities.
    • Addressing the communication needs of nonspeaking populations with complex physical and sensory challenges.

    Observation:

    • Two distinct communication systems were designed, incorporating speech synthesis to aid users with visual impairments.
    • Case studies involved a 24-year-old with optic glioma and a younger individual with cortical blindness and motor limitations.

    Findings:

    • Both participants successfully acquired the skills to operate their respective communication systems.
    • One participant demonstrated limited sustained independent use, attributed to reduced vigilance and attention span.

    Implications:

    • Speech synthesis is a viable feature for enhancing usability in assistive communication devices for visually impaired users.
    • Further research is needed to optimize system design for individuals with cognitive challenges affecting sustained use.
