Ventriloquism is an act of stagecraft in which a person manipulates his or her voice so that it appears that the voice is coming from elsewhere, usually a puppeteered dummy. Originally, ventriloquism was a religious practice. The name comes from the Latin for to speak from the stomach, i.e. venter (belly) and loqui (speak).
The noises produced by the stomach were thought to be the voices of the unliving, who took up residence in the stomach of the ventriloquist. The ventriloquist would then interpret the sounds, as they were thought to be able to speak to the dead, as well as foretell the future.
