Many people believe that ghosts can communicate with us, while others are skeptical of such claims. A common tool used by paranormal investigators is EVP - also known as Electronic Voice Phenomena. EVP is speech (or speech-like sounds) heard on electronic devices but not heard in the environment at the time they are recorded, In EVP recordings, human-sounding voices will actually respond to questions posed by investigators, comment on situations, and will sometimes address paranormal investigators by name, These voices have been recorded on a variety of electronic devices such as tape recorders, digital voice recorders, and video recorders. Strangely, the voices are not heard at the time of the recording - it is only when the recording is played back that the voices are heard. There are hundreds of these voices documented - maybe even thousands. Researchers all over the world are capturing EVP's, and many of these voices have accents, and show strong emotion. These voices can respond to you, answer questions, and even ask questions of their own.
