HL2 - Civil Protection vocoder?

[siXMan]

Does anyone know what voice modifier Valve used to produce the electronic voices of the Civil Protection guys in Half-Life 2? I would like to make my own Civil Protection dialogue, but I require a good vocoder.

Lol the first clip sounds like Arnold Swartsnagger (I have no idea whether I spelled that right or not, probably not)

lmao.

But yes, look at the second page of the thread. It isn't actually that hard to do at all, it's just getting it to sound very similar, which is of course not easy since you don't have the voice of the original voice artists.
