EVPs..Their 'official' name is Electronic Voice Phenomenon. Many people that go on ghost hunts carry either a tape recorder with a clean tape inside, or an electronic/digital recorder and go around asking questions, in the hopes of getting a response on playback.

This is the best way to hear a ghost/spirit speak to you. The definition of EVP via http://en.wikipedia.org/wiki/Electronic_voice_phenomenon is...

"Electronic voice phenomena (EVP) are electronically generated noises that resemble speech, but are not the result of intentional voice recordings or renderings. Common sources of EVP include static, stray radio transmissions, and background noise. Some have claimed these sounds are of paranormal origin,^[1] while there are natural explanations such as apophenia (finding significance in insignificant phenomena), auditory pareidolia (interpreting random sounds as voices in their own language), equipment artefacts, or simple hoaxes. Recordings of EVP are often created from background sound by increasing the gain (i.e. sensitivity) of the recording equipment."

Personally, I have never had this happen for me. And actually, I have never tried. But I would love to.

There are also three different Classes of EVP. Class A, being the clearest you can capture. Class C, being the lowest in comprehension.

Here are a couple of videos that I have found that have obtained Class A EVPs...

(In this one, at the beginning a skelleton with a top hat kind of "bounces out" at you in their logo. Don't be alarmed.)





In this next one, it's pretty amazing how clear the answers are. This is what would be called an Intelligent Haunting or spirit. The only thing I do not like about this, is the fact that the person recording all of this is using an Ouija Board, which I highly recommend against, due to personal experience years ago.




For the last video, this man has picked up EVPs of children who have passed away, but are stuck between this world and the next plane of existence...Not for the faint of heart when it comes to kids.
