There are two types of sound: Diegetic Sound is which characters on screen can hear and can include sound effects, the sound made by movements and spoken dialogue. Non-Diegetic Sound is any sound which does not come directly from the world of the story onscreen. Sound contains further elements/types ; Dialogue is defined as a conversation between two or more people in a movie , furthermore a film can have a monologue where the actor is speaking out loud if only in a room. Sound effect is any other sound other than music or speech artificially re-produced to create an effect in dramatic presentation.
