Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Phonoscène
The Phonoscène was a forerunner of sound film. It combined a chronophone sound recording with a chronograph film shot with actors lip-synching to the sound recording. The recording and film were synchronized by a mechanism patented by Léon Gaumont in 1902. The first Phonoscènes were presented by Gaumont in 1902 in France.
