Character A is out of sight (under a desk, behind a screen, etc) and for some reason is talking to himself. Character B enters the room and hears talking. Looking around, Character B spots a cell phone / mannequin / sleeping person / inanimate object and assumes that it is the object doing the talking.
This trope describes any situation in which a character is speaking, and other characters believe the voice is coming from another person or an inanimate object, and this was not the intention of the person speaking. If the speaker achieved this effect deliberately, then it's just an example of ordinary Ventriloquism. Compare Multitasked Conversation, Correlation/Causation Gag.
