In 1929, the film "Finding His Voice" was originally commissioned by the Electrical Research Products Incorporated division of Western Electric,
which takes credit for the story, E.R.P.I. It was originally intended as a demonstration film for theater owners, projectionists and sound technicians.
Although it tends to get a bit lost within its own technicalities, the animation helps to keep a rather dry subject entertaining. The situation is personified by two rolls of film,
one called "Talkie," the other "Mutie." Throughout the film, ERPI intended to explain new technologies of talking motion picture, who could know them easily, which they developed.
