Summary
This study shows a computer system effectively functions as a microswitch for word utterances in adults with multiple disabilities, enabling access to preferred stimuli.
Area of Science:
- Assistive Technology
- Speech-Language Pathology
- Rehabilitation Engineering
Background:
- Individuals with multiple disabilities often face challenges with communication and environmental control.
- Conventional microswitches typically rely on motor responses, which may be limited for some individuals.
Observation:
- A novel computer system integrating custom software and speech recognition was evaluated.
- The system was designed to function as a microswitch activated by word utterances.
Findings:
- Participants demonstrated increased frequency of targeted word utterances.
- The computer system achieved approximately 80% accuracy in recognizing these utterances.
- This facilitated high levels of access to preferred stimuli for participants.
Implications:
- Computer systems can serve as effective microswitches for individuals with severe speech impairments.
- This technology expands the potential applications of microswitch systems beyond traditional motor-based controls.
- It offers a promising alternative communication and control method for individuals with complex needs.
