Electronic voice phenomena (EVP) is a term coined by Colin Smyth to describe speech or speech-like sounds of paranormal origin occurring on previously unused recording media.

As with other paranormal phenomena, the existence of EVP is disputed. EVP researchers Alexander MacRae and Judith Chisholm hypothesis that it is caused by psychokinesis or the voices of spirits. Skeptics, however, say they can be explained by such things as pareidolia or radio interference.

Examples of EVP are typically reported to be brief, the length of a word or short phrase, though longer examples are also reported. They are usually in a language understood by those present at the time of recording.
