Ever tried creating these special robotic voices the really sound radiating on it’s own?
You probably tried trickery by ring-modulate a tone through your existing voice-speech.
Here’s a little neat secret:Whisper instead of speaking and use ringmodulation upon that.
I used to do this years ago. Lots of fun 
What about using a delay or early reflections - it makes it sound like metal.
Or try msreader or the old proggy, which benni benassi used for satisfaction (I don`t remember the name).
There are lots of tricks to rape your voice…
An excellent example is “Somnambulist” from BT.
a good one to get “robotic voice” is to speak and not to exhale while speaking, but to speak while inhaling. needs a little bit of practice i think, but you don’t even need any (computer-)effect. 
thats a great idea, i completely forgot about that!
playing with some comb filters would also sound pretty nice, especially on whispers.
on OSX there is a very splendid selection of included voices that you can control with supercollider3. theres about 15-20 something different voices. you can control everything you could imagine when dealing with the voices also. everything from HAL to a histerical laughing voice. theres even some that work on rythyms. i havent figured out if the rythyms can be changed yet but im hoping they can. i’m lead to beleive that since sc3 can do this max/msp and pd should also be able to partake in this.
like something along the lines of Hrvatski’s Catstep/My Kitten/Catnap Vatstep dsp Remix.
orange vocoder 2.02 can do robotic voices too
Not a best ever vocoder btw… But with own character.
Very cool thing i’ve found lately:
Prodyon Robocoder.
Recommend 2 check it outta. Very useful and inspiring piece of art
Not robotic voices, but you can use them in your tracks none the less.
More realistic sounding.
Give this a try for fun and then add some effects to them.
Did “MC Hawking” happen to influence you with this track?
I noticed some of the lyrics are VERY similar to Quakemaster…
Here is a tip! The best way is to acctually build a robot and then sample it when it speaks. Than you will have true robotic voice samples!
Or you could just hire a robot, but that is not as original…
