Psychophony

Psychophony (from the greek psyke, soul e phone, sound, voice) is the name given by Spiritism and some other spiritualist traditions to the phenomenum where, according to them, a spirit talks using the voice of a medium.

The Spiritist Doctrine codified by Allan Kardec identifies two main classes of psychophony, to say, the "conscious" one and the "unconscious" one. The first one, as its name says, happens when the medium assures that he has mentaly perceived or physically heard something that a spirit said, having only used his voice to reproduce it. The second one occurs when the medium assures that he ignores what was said, suggesting that a spirit used his phonetic organs while he was unconscious. As happens with all sorts of classification, this one must be accepted only for didatic purposes. Most psychophony occurrances are neither 100% conscious nor 100% unconsious laying somewhere between the two classes.

In The Mediums' Book, Allan Kardec calls unconscious psychophonic mediums "speaking mediums".
