Automated dialogue replacement (ADR) is a standard post-production technique for adding spoken sound in contemporary film and television. This chapter discusses ADR's role in the production of a coherent match of voice, sound and vision that is crucial to the mainstream Hollywood style, in particular in technoscientific genres, where much of the action takes place on screens inside the narrative. The sounds made by computer screens and computer operators, as well as the sounds attributed to babies, are examined in particular. The concept of enunciation is used to explain the interplay of redundancy, information, communicative acts, and repetition in the production of meaning in several film and television genres, especially in productions released in the digital era.
