Human-factors aspects of designing computer voice output systems as communication aids for the disabled

Abstract

Possible ways of meeting the user's needs when designing communication aids with synthetic voice output are discussed. The points raised evolved from a case study of the development of microcomputer based systems which the blind people can use to read page-oriented text. The ideas discussed in this paper may also enhance the performance of blind computer programmers. Essential facilities in communication aids for the non-vocal are also inferred.
