How to Make Your Voice Sound Robotic

By Jeff Grundy

In addition to the basic Sound Recorder utility that ships with Windows, there are hundreds of both freeware and commercial programs you can download and use to record your voice. Most of these applications require little more than a microphone and the click of a mouse to create a recording. However, if you would like to alter your voice in the recording -- for example, to add a robotic voice effect -- you must use a voice morphing application.

Download and install a voice morphing application. Programs such as AVS Voice Changer, Fake Voice, VCS Diamond and MorphVOX Voice Changer all allow you to change the pitch of your voice or add special effects, including a robotic voice, to recordings.

Connect the microphone to the "Microphone In" port on your computer. The port may be on the back, the rear of the computer or both. The port usually has a pink ring around the hole.

Click "Start," then "Control Panel." Click the "Hardware and Sound" option in the "Control Panel" window, then the "Sound" link.

Click the "Recording" tab, then highlight the "Microphone" option. Click "Apply," then "OK."

Launch the voice morphing application. Click the "Settings" or "Filter" option on the menu or tool bar. Select the "Robot," "Computer" or "AI" voice option, then click "OK" or "Save." Click the "Test" or "Preview" button, then speak into the microphone. Your voice should sound mechanical or robotic when heard through your computer speakers.

Launch "Sound Recorder" or another recording application on your computer. Click the "Record" button or link in the application in the program window. As you speak, the filter in the voice morphing program changes the pitch of your voice before reaching the recording software.

Click the "Stop" button in the recorder program and save the recording file. Open the file in Windows Media Player or another media player application. Once you click "Play" in the media player, you should hear your recording with the modified pitch settings.
