Anomalous Voice Phenomena (EVP)

Anomalous voice phenomena — commonly, electronic voice phenomena (EVP) — are reported instances in which a recording device is said to capture voices that were not heard at the time of recording. The source presents the 1952 tape-recorder episode involving Pellegrino Ernetti and Agostino Gemelli as "an early account of anomalous voice phenomena."

The episode as reported

Per Peter Krassa's book, on 15 September 1952 Ernetti and Gemelli were working on a tape recorder that frequently broke down. Gemelli had for years silently addressed his deceased father for guidance, though he believed he had never received a conscious reply. Frustrated, he called out to his father for help. When the recording was replayed after repair, both men heard a voice they identified as Gemelli's father saying:

"Of course I shall help you. I'm always with you."

Gemelli was distressed; Ernetti continued the experiment. On repeating the procedure, the recorder allegedly captured a clearer voice:

"But, Zucchini, it is clear, don't you know it is I?"

The nickname "Zucchini," the story holds, was a childhood name known only to Gemelli and his father. The two men reportedly brought the matter to Pope Pius XII, who assured them the discovery was purely scientific and could reinforce belief in an afterlife.

Status in the source

The source presents this as narrative, not verified fact. It offers no recording, no technical analysis of the tape, no independent witness, and no document for the reported papal audience. The episode functions in the source as the origin story of the Chronovisor project, a linkage asserted by Krassa and not independently corroborated.

Why it matters here

The episode is the only element of the source that touches on a broader class of claims — voices captured by recording equipment — and it is the narrative hinge connecting a 1952 anecdote to a 1972 device claim. It is recorded here as a claim category, not as evidence for the Chronovisor.
