Micro-Based Speech Recognition: Instructional Innovation for Handicapped Learners.
Horn, Carin E.; Scott, Brian L.
A new voice based learning system (VBLS), which allows the handicapped user to interact with a microcomputer by voice commands, is described. Speech or voice recognition is the computerized process of identifying a spoken word or phrase, including those resulting from speech impediments. This new technology is helpful to the severely physically handicapped individual who cannot use a keyboard. The VBLS makes many previously inaccessible electronic instructional aids available to physically disabled learners, and involves them in their own educational/vocational progress. The VBLS system's software is written in assembly code and BASIC. During the study or learning component of the system, the student user says a lesson vocabulary word/phrase, reads the related question, and vocally answers the question aloud into the system's microphone by saying the prompted correct response. Master templates are adapted to each user's unique speech patterns as part of the instructional design logic. The VBLS system can be adapted to varying skill levels: physical, cognitive, and communicative. Additionally, a word drill study option provides the student with real time pronunciation feedback. Finally, there are over 40 options available so that a lesson can easily be adapted to focus on the student user's ability and learning sequence preferences. Information is presented on: the logic of a speech recognition system, and configuration of an environmental control system, the algorithm for word verification, the instrumentation and cost, and general principles of how the system works.
