Franklin S. Cooper

American physicist and inventor (1908–1999)

Franklin Seaney Cooper (April 29, 1908 – February 20, 1999) was an American physicist and inventor who was a pioneer in speech research.

Biography

He attended the University of Illinois where he received his undergraduate degree in physics in 1931, and received his Ph.D. in physics from the Massachusetts Institute of Technology in 1936. In 1935, with Caryl Haskins, he founded Haskins Laboratories, a nonprofit research laboratory that is located in New Haven, Connecticut, and studied speech and language. His primary interest was in speech synthesis and perception, which led him to invent the pattern playback, 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 Vannevar Bush, Cooper took a position in the Office of Scientific Research and Development. He also returned to Washington in 1973, when he was selected to form a panel of six experts charged with investigating the famous 18-minute gap in the White House office tapes of President Richard Nixon related to the Watergate scandal .

Cooper was the president and director of research at Haskins Laboratories from 1955 to 1975. During this period he directed and provided theoretical input and guidance to many projects, including the Haskins prototype for the reading machine for the blind. He also advocated a program in electromyography to look "upstream" in the musculature at the control of motor activity in speech. He was an early advocate of the motor theory of speech perception. This led to a great deal of work at Haskins on the physiological mechanisms underlying the production of speech carried out under the leadership of Katherine S. Harris.

Cooper had many academic positions and affiliations. He was the winner of many awards, including the Silver Medal from the Acoustical Society of America. After stepping down as president and research director at Haskins Laboratories, he served as associate research director until 1986. After retiring, he moved to Palo Alto, California, in 1989.
