, an early electromechanical device for synthesizing speech. It became a forerunner of contemporary computer-based speech synthesis programs and was used by many scientists at Haskins to discover the critical cues for speech synthesis and recognition. Cooper designed other special-purpose synthesizers in the early 1950s, including Octopus, Voback, Intonator, and Alexander. Of these four, only the Voback and the Intonator, which were "parasitic on Homer Dudley's Vocoder", were used extensively for perceptual experiments. He was aided in the construction of these devices by the late John M. Borst. During World War II, at the request of
