  1. 1

    Download software to your mobile phone such as Bluff My Call or Voice Changer that will allow you to change your voice on the phone. This is truly the easiest way to disguise your voice. Some of these programs will even let you hide or change your mobile phone number as well.

  2. 2

    Choose the voice that you would like to use when making your call. Common options include: old woman, old man, baby, school girl, etc. Make your call as normal with your selection. Talk normally into the phone and it will change your voice.

  3. 3

    Purchase a handheld voice changer. This is the kind that the villains famously used in the "Scream" movies. Turn the voice changer on, adjust the volume and place it over your mouth as you make a call.

Tips and warnings

  • Don't try to muffle the mouthpiece of a phone with a sock or other piece of fabric to try to disguise your voice. It will just make the other person have difficulty hearing you, and your voice will be entirely recognisable.
  • Bear in mind that changing your voice with the intent to commit fraud is illegal.
