The spirit box is a piece of ghost hunting equipment in Phasmophobia, the co-op horror game released by Kinetic Games in 2020, which lets players ask the ghost questions and receive garbled vocal replies. Short response clips like this one spread through Twitch streams and YouTube ghost hunt videos, where the flat robotic delivery became a recognizable shorthand for talking to the dead. It now sits alongside other horror game sounds like the Fears to Fathom notification and the FNAF jumpscare scream in meme edits and soundboards.
