How to Change Your Voice During a Call
Being able to change one's voice is an interesting concept that can be applied in many ways to personal phone calls, such as playing tricks on friends or sounding much older or younger than you normally would. With a microphone, voice-changing software and VoIP (Voice Over Internet Protocol) software for the computer, it's simple to change one's voice so that the person on the other line hears a voice that's not your own.
Download voice-changing software to your computer (see Resources).
Install the voice-changing software to your computer by following the onscreen steps provided with the installation program.
Run the voice-changing software by double-clicking on the newly created shortcut icon on the desktop.
Configure the program to work with your microphone by selecting the "In" option to your built-in or external microphone. In most cases it will already be selected.
Read the instructions or help file that came with the program. All voice-changing programs are different but have the same basic controls and, by reading this, you will familiarize yourself with the program.
Download and install VoIP software if you do not already have this software (see Resources).
Use the VoIP software to call someone by entering the recipient's user name or phone number, depending on the program.
Speak into the microphone. Depending on the voice-changing program you may or may not hear your own voice, but the person you're calling will hear the changed voice on the receiving end.
Change options with the voice-changing software to your liking by either moving the pitch up or down or using preset effects. There often will be an option to hear yourself talk so you can change your voice in real time and hear what it sounds like.
