Development and Evaluation of an Accessible Voice Recognition System (AVRS) for Individuals with Intellectual

Individuals with significant cognitive impairments have among the highest incidence of illiteracy. This, combined with the complex and text based interfaces of mainstream computer programs and operating systems, makes typical keyboard input largely inaccessible to this population. Voice recognition technology offers promise to overcoming this barrier, but currently provides the same barriers of excess complexity and text-based interfaces that prohibit access to those with limited conceptualization abilities and reading skills. For example, typical voice recognition software applications employ feature-rich text based dropdown menus and require users to read extensive on-screen text as a means of training the system to their unique voice qualities. This project is proposed to address these issues by employing proven multimedia, error minimization and other universal design software development techniques to create a simplified voice recognition application that is independently usable by individuals with a range of intellectual disabilities. Specifically, this project proposes research, development and feasibility evaluation of an Accessible Voice Recognition System (AVRS) that will enable students and adults with significant cognitive impairments to more independently control and navigate through computer operating systems and to create a variety of personal text documents.
