The document represents an attempt to produce a system, called the HEARSAY system, capable of accepting speech input, understanding spoken messages, and generating voice responses. This system has as subparts a speech recognition system, a question-answering system, and a speech generation system. A task is a system capable of answering questions, obeying commands, andor accepting facts for future use. In a speech understanding system, a task has a corresponding task language, which is a formal language with an associated semantic interpretation. Two tasks are implemented in the HEARSAY system. The first, voice-chess, accepts spoken chess moves and speaks response moves. The second, voice-programming, accepts simple spoken algebraic expressions and speaks their values. Some preliminary results obtained on the HEARSAY system are presented. Modified author abstract
