Reading aids for the blind: A special case of machine-to-man communication

Abstract

The development of a reading machine for the blind offers insight into current problems of computer-to-man communications and poses a technical and humanitarian challenge. Approaches to the problem include compiled speech, reformed speech, and synthesis by rule. Of these methods, synthesis by rule may offer the best long-term trade-off between quality of the speech and cost and complexity of its production. Implementation of a high-performance reading machine will involve a central service facility that can generate tape recordings or provide voice responses to remote print scanners. Technical problems, especially in providing remote on-line service, seem formidable, but the organizational problems of matching central facilities to the blind user's needs may prove to be even more so.
