A novel approach to programming computing machinery is demonstrated by the EnguageTM language engine: programming by utterance. The running of a command is modeled as a deductive process; the mechanism by which meaning is ascribed to utterance—induction—is described. A full example of the factorial function is given. The paper then develops utterance not only as a form of issuing commands to hardware, but also of storing, retrieving, and manipulating spoken information—a programmable UI. Because such utterances can be generated by speech-to-text software, such interactive computation does not require a program as a written artifact.
