Electronic voice phenomenon (EVP) is a term used to describe the supposed communication from spirits or ghosts through electronic devices. There are several synonyms for the term, such as Instrumental Transcommunication (ITC), Voice Phenomena (VP), and Electronic Transcommunication (ETC). The term EVP gained popularity in the 1950s and continues to be used today. ITC is a broader term that includes various methods of communicating with spirits or ghosts, including EVP. VP refers solely to the audio manifestations of spirit communication, whereas ETC is a more recent term that encompasses EVP and other forms of electronic communication from the afterlife. Regardless of the term used, the concept of receiving messages from the deceased through electronic devices remains a fascinating area of paranormal research.
