Speech understanding systems

A five-year interdisciplinary effort by speech scientists and computer scientists has demonstrated the feasibility of programming a computer system to `understand' connected speech, i.e., translate it into operational form and respond accordingly. An operational system (HARPY) accepts speech from five speakers, interprets a 1000-word vocabulary, and attains 91 percent sentence accuracy. This Steering Committee summary report describes the project history, problem, goals, and results.
