From the Star Wars movies to the Lost in Space TV series, digital robot voices have been used for years. While it used to take thousands of dollars and special equipment to change voices, you can now achieve the effect in a matter of minutes with Adobe Premiere editing software. Apply the Flanger audio effect to any audio clip to transform a normal human voice into a grating robot voice. The key to perfecting the sound is making the right adjustments as you edit the track.

Step 1

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.

Step 2

Click the Effects tab and expand the Audio Effects sub-menu.

Step 3

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 audio type will be listed in the center of the properties.

Step 4

Expand the audio sub-menu. Drag and drop the "Flanger" effect on to the audio clip.

Step 5

Open the Effects Tab next to the Monitor Window. Click the Flanger menu to expand the options.

Step 6

Expand the Custom Setup menu. Five different adjustable options will appear: "Rate," "Depth," "Delay," "Feedback" and "Mix."

Step 7

Adjust the Rate from "8.0" to "10.0." This duplicates the voice to create the metallic sound of a robot. Play the clip and make adjustments to suit your custom needs.

Step 8

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.

Step 9

Set the Feedback to "0.0." This will remove any echo and make the words easy to understand.

Step 10

Change the Delay to anything from "10.00" to "30.00." Play and adjust as needed.

Step 11

Set the Mix. This creates the final voice and removes the original tone. Set this above "60.00" to completely remove the original voice. Playback after each setting to make sure it sounds clear.

Tip

Click the "Eye" icon on other sound and video layers to temporary hide them so you can focus on just the robot voice audio.
