Spirits do not actually have voices, but in order to
communicate clearly and explicitly they must express their
thoughts in a way that human minds are able to deal with -- in
words. They cannot form actual words, but they can trigger the
impression of words in the human mind, and this is easier with the
help of some background noise conducive to the impression of voices.

I see your point, but until you do a recording yourself and pick up a
voice speaking your name or of some other relevance in a loud and clear
manner then you really haven't understood EVP, because trust me - it'll
leave you scratching your head and probably invoke a little fear for
first-timers.

There is the question of poltergeist phenomena -- the possibility
that a spirit can, in some unknown manner, use the energies of a
human host to cause changes in the physical environment in
nonstandard ways. I think this kind of event may occur, based on
the recorded eye-witness evidence for it, but it is also possible
that some other factor is at work (deception used by the possessed
host; self-deception on the part of the witnesses).

If poltergeists exist, then it is not beyond possibility that
spirits can use human energies to modify physical recording
devices. I tend to believe this does not happen, but I would not
dismiss the possibility out of hand.
