what were "talkies" in the roaring 20s?

"Talkies" were films with synchronized sound or audio recordings, which emerged in the late 1920s. Before the 1920s, silent films were the predominant form of cinema, where the actors' performances were accompanied by live music, sound effects, or intertitles (written dialogue or explanations). However, the introduction of synchronized dialogue and sound effects revolutionized the film industry. The popularization of "talkies" began with the release of The Jazz Singer in 1927, which employed synchronized sound sequences. It marked a turning point in film technology and entertainment, as it allowed for a more immersive cinematic experience. The advent of talkies not only transformed the film industry but also had broader cultural and social impacts in the 1920s, encompassing changes in entertainment, fashion, and trends.
