What do we call the voice prompt we hear after a kill?

What do we call the voice prompt we hear after a kill? For example: "Double kill", "Killionaire". What do we call those? I am pretty sure there's a slang or a word people use in-game that refers to it. The general word for it would be "voice prompt", but I doubt people refer to them as that.

I am referring to the lines and not the voice.


Solution 1:

I would use the word announcement, at least in Unreal Tournament that's what is generally called. And it makes sense, as the announcer reads it out.
