How to sound like a robot in adobe Audition:
First, record your voice to be saying whatever you want your robot to say. After you have that done, go to Effects>Generate>Tones. You should see a panel with a ton of options and sliders pop up, which can be a bit overwhelming. Go to the Presets tab and select the Chord preset. Look further down on the panel and click "> Advanced". An extra section of the panel should drop down. Right below "DC Offset" change the "Replace" to "Modulate". Now apply the effect, and it should sound pretty robotic!
