From "Star Wars" to "Lost in Space," digital robot voices have been used for years. While it used to take thousands of dollars and special equipment to change voices, it can now be done in a matter of minutes with Adobe Premiere editing software. The audio effect "Flanger" can be applied to any audio clip to transform a normal human voice into an unrecognisable robot voice. The key to perfecting it is making the right adjustments as you edit the sound.
Open the Premiere project that you want to apply the robot voice to. Audio clips with voice only make the best sound clips to adjust. Any background music or sound effects on the same audio clips will be transformed too.
Click on the "Effects" tab and expand the "Audio Effects" sub-menu.
Select the option that defines what your audio clip is--either "5.1," "Stereo" or "Mono." If you don't know, right-click on the audio clip and select "Properties." The type of audio will be listed in the middle of the properties.
Expand the audio sub-menu. Drag and drop the "Flanger" effect onto the audio clip.
Open the "Effects Tab" next to the "Monitor Window." Click on the "Flanger" menu to expand the options.
Expand the "Custom Setup" menu. Five different adjustable options will appear. They are "Rate," "Depth," "Delay," "Feedback" and "Mix."
Adjust the "Rate" from "8.0" to "10.0." This will help duplicate the voice to create the metallic sound of a robot. Play the clip and make adjustments to suit your custom needs.
Set the "Depth" from "70%" to "100%." The exact setting depends on how deep the original voice was. Choose a setting, play a preview and then adjust as needed.
Set the "Feedback" to "0.0." This will remove any echo and make the words easy to understand.
Change the "Delay" to anything from "10.00" to "30.00." Play and adjust as needed.
Set the "Mix." This will create the final voice and remove the original tone. Set this above "60.00" to completely remove the original voice. Playback after each setting to make sure it sounds clear.
Click on the "Eye" icon on other sound and video layers to temporary hide them so you can focus on just the robot voice audio.
