TITLE: INTELLIGENT AAC SYSTEMS: WHAT CAN BE DONE NOW AUTHORS: Kathleen F. McCoy, Eric H. Nyberg, Bruce R. Baker COMMENTS: (c) 1990 RESNA Press. Reprinted with permission. ABSTRACT: With the advent of smaller, more powerful computers, it is becoming possible to develop AAC systems which take advantage of Artificial Intelligence and Computational Linguistics techniques. In particular, we envision the development of an 'intelligent' AAC system that can understand the operator's input well enough to infer what words or syntactic structure may be omitted or missing, enabling the device to output a complete and correct sentence from partial input. At some point in the future it may be possible to create an AAC system with all of the linguistic knowledge of a human speaker, but the limitations of existing theory and technology allow only a small subset of that knowledge to be incorporated in current systems. In this paper we explore some of the possibilities for AAC systems that could be developed given the present state of affairs. Of course, each of the possibilities must contain trade-offs of one kind or another. We discuss various populations of potential AAC system operators and show how different populations would benefit from different aspects of 'intelligence' in their system.
