"If we're going to be consistent and advocate freedom of speech we have to advocate freedom of encrypted speech too. The genie is out of the bottle, cryptologically."
In his 1959 novel Starship Troopers, Robert Heinlein refers to talking bombs that speak an alien language (to creatures called "skinny's").
The closest thing to a talking grenade is the flashbang grenade, created for Britain's Special Air Service for use in anti-terrorist actions. Flashbangs emit a piercing 175 decibel sound along with an actinic flash that blinds victims for about five seconds. Flashbangs were developed in the mid-1970's.
