La voce del padrone

His Master's Voice (original Polish title: Głos Pana) is a 1960s science fiction novel written by Polish writer Stanisław Lem. It was first published in 1968 and translated into English by Michael Kandel in 1983. The book incorporates a "message from space" theme. It is a densely philosophical first contact story about an effort by scientists to decode, translate, and understand an extraterrestrial transmission. The novel critically approaches humanity's intelligence and intentions in deciphering and truly comprehending a message from outer space. It is considered to be one of the three best-known books by Lem, the other two being Solaris and The Cyberiad.
