More about this voice

A machine that still sounds like a man

Part	Setting	What you hear
Depth	Pitch -5, Tone -3	A big, relaxed low voice
Machine	Robot 40 Hz, 25% mix	A low flutter under the voice, not over it
Metal skin	Flanger 0.15 times a second, 40% mix	A slow sheen, like sound off polished steel
Digital trace	Bit crusher 12-bit, 20% mix	A fine grain you notice only on held vowels
Room	Reverb 15%, 1 s	A large quiet hall behind him

Sound amused, not robotic

Talk like a person, with full melody and sarcasm. The buzz is only at 25%, so a flat robot delivery wastes the voice.
Keep the pace easy and conversational, then slow right down for the final phrase.
Favour long, reflective lines about people and their flaws over barked orders.
Smile slightly while you speak; the contempt is audible.

Ultron, Optimus Prime or the evil robot?

All three are deep machines. The Optimus Prime-style voice is nobler and cleaner: buzz at only 10% and a longer 1.4-second reverb. The evil robot is the opposite, its 40 Hz buzz at 60% plus distortion, a machine with no person in it. The Ultron style sits between them, smooth enough for long speeches. The second clip here raises the buzz to 50% for less man and more metal, and the third drops the bit crusher for a calm, almost human machine.

Free Ultron voice changer FAQ

Is this the voice from the Avengers film?

No. It's a voice in that style made from a pitch shift, a ring modulator and a flanger. It contains no film audio.

Can I stream with the Ultron voice on Twitch?

Yes, if you go live from Twitch's browser streaming studio in Chrome: choose Facecam Virtual Mic as the microphone there. Desktop streaming software can't see that mic.
