These voice changers allow you to change your voice to an unfamiliar voice. The vast majority of "voice changers" shift the pitch-sensitive fundamental waves of the users voice (via microprocessor) and offer various pitch shift options. "Low end" models offer less pitch options and use a less effective (and lower cost ) microprocessor than "high end" models. Since pitch is only one element of the human voice, there are limitations as to how much change can be made without resulting in an "unnatural" or "digital" sounding voice. High end (Pro) models use additional electronic circuits to offset or buffer the unnatural sounds as well as more efficient pitch shifting microprocessors.

Can I Really Change A Female Voice To a Male Voice And Vice Versa?

Since everyone's voice is different, everyone's result when using a voice changer is somewhat different. Generally speaking, a voice changer can increase or decrease the pitch of your voice by one or two octaves while maintaining a realistic sounding result. They do, in fact, a very efficient job of disguising your voice even to people who know you well. Most people can find two or three settings on the voice changer that, with a little practice, can have amazing results. The more selection options the voice changer offers, the better the results and the more "voices" you can effectively use. However, for a typical male voice to sound like a typical female voice or vice versa, you must change the voice by several octaves. This usually results in a voice sounding like Mickey Mouse or Darth Vader. The same applies to a child to adult sound and adult to child sound. On the other hand, some customers have reported good results in "gender" changing. We believe this to be rare exceptions to the rule, however.
