Using computer systems as microswitches for vocal utterances of persons with multiple disabilities.

Area of Science:

• Assistive Technology
• Augmentative and Alternative Communication (AAC)
• Disability Studies

Background:

• Individuals with multiple disabilities often face challenges in vocal communication.
• Computer-based systems offer potential solutions for enhancing communication and access to stimuli.
• Previous research highlights the need for tailored technological interventions.

Purpose of the Study:

• To evaluate the efficacy of two distinct computer systems as microswitches for vocal utterances.
• To assess the impact of these systems on utterance frequency and engagement in adolescents and young adults with multiple disabilities.
• To determine the long-term effectiveness of the intervention.

Main Methods:

• Two participants with multiple disabilities (adolescent and young adult) were involved.
• Custom and commercially integrated software programs were utilized as computer-based microswitches.
• The systems were designed to respond to specific vocal utterances by presenting preferred stimuli.
• Intervention effects were measured by utterance frequency and levels of stimulation obtained.

Main Results:

• Both participants demonstrated a significant increase in the frequency of their target vocal utterances.
• Participants achieved high levels of stimulation through the computer systems.
• The positive effects on utterance frequency and engagement were maintained during post-intervention assessments.

Conclusions:

• Computer systems, acting as microswitches, can effectively enhance vocal communication for individuals with multiple disabilities.
• Tailored software and integrated speech recognition programs show promise in facilitating access to preferred stimuli.
• The findings support the use of technology-assisted interventions to improve communication outcomes in this population.
