This paper reports the development of a computer-aided conversation prosthesis which is designed for severely physically impaired non-speaking people. The research methodology was to model aspects of conversational structure derived from the field of conversation analysis within a prototype conversational prosthesis. The prototype was evaluated in empirical investigations which also suggested successful strategies for carrying out satisfying conversation using such a system. Two versions have been built and tested, one using an able-bodied operator to test the feasibility of creating conversation from prestored material, the second being used by a physically impaired non-speaking operator. The prototype demonstrated the advantages of this interface design in helping the user to carry out natural sounding and satisfying conversations.
