Same with this photo that's been making the rounds on the paranormal forums.

We skeptics are supposed to be the rational ones. Let's try and set an example.
Whoops… looks like one got out. If you see a Grim on the loose… please return to Insomniac Games, Burbank, CA: http://bit.ly/fqGoXX.
It first appeared on Wildgame Innovation's Facebook page. It is a picture reportedly snapped by a deer hunter on a reserve in Berwick, near Morgan City, Louisianna [sic]. It was originally being passed off as real, but now inside sources close to the production say its actually a viral image from Super 8 (the Steven Spielberg-produced and J.J. Abrams-directed alien flick ). There is even video from a young Weirton, West Virginia extra called "Crying Girl", who talks about having a run in with this creature in the movie.
Raudive developed several different approaches to recording EVP, and he referred to:
Raudive delineated a number of characteristics of the voices, (as laid out in Breakthrough):
Sine-wave speech is a form of artificially degraded speech first developed by Robert Remez and Philip Rubin at Haskins Laboratory.
In this work, Remez and colleagues demonstrated a dramatic change in the way in which sine-wave speech sentences are perceived, depending on listener's specific prior knowledge.
Most naive listeners hear this as a set of simultaneous whistles, or science fiction sounds. However, for listeners that have previously heard this "sound" . Now listen to the first again.
Listening to the sine-wave speech sound again produces a very different perception of a fully intelligible spoken sentence. This dramatic change in perception is an example of "perceptual insight" or pop-out. We have argued that this form of pop-out is an example of a top-down perceptual process produced by higher-level knowledge and expectations concerning sounds that can potentially be heard as speech
Here is another example:
The problem is that anyone recording these "voices" (in the case of ghost hunting) is already looking for them. They have a prior bias and are going to over- examine any anomalous sound and claim they hear speech. I believe that in most cases, the real culprit behind hearing voices of the dead in your tape recordings is Paradoilia. Yes, the same reason you see Jesus in your cheetos. After all, how is the spirit of a deceased person able to produce sound without vocal chords? The human brain is a very powerful tool, able to proccess random information into recognizable images and sounds. This is how we developed language and writing. Don't sell yourself short by writing these sounds off as something paranormal.
