Electronic voice phenomena, abbreviated as EVP's (singular: electronic voice phenomenon, or EVP), are sections of static noise on the radio or electronic recording that some listeners believe sound like voices speaking words; paranormal investigators sometimes interpret these noises as the voices of ghosts or spirits. Recording EVP has become a technique of those who attempt to contact the souls of dead loved ones or during ghost hunting activities. According to parapsychologist Konstantin Raudive, who popularized the idea, EVP are typically brief, usually the length of a word or short phrase.

Skeptics of the paranormal attribute the voice-like aspect of the sounds to apophenia (finding of significance or connections between insignificant or unrelated phenomena), auditory pareidolia (interpreting random sounds into voices in their own language which might otherwise sound like random noise to a foreign speaker), artifacts due to low-quality equipment, and simple hoaxes. Likewise some reported EVP can be attributed to radio interference or other well-documented phenomena.
