some technical information - voice changers
Since most people are unfamiliar with what the "formant" component of the human voice is, here are the details :
Human
voices consist of two components -
one is fundamental waves that are pitch-sensitive and the other is non pitch-sensitive
fixed harmonics.
The harmonics components that change along with vocal cords and with the physical shape of the
vocal tract and which add the distinctive characteristics to a person's voice, are caller formants. Most of the telephone voice
changers on the market today are strictly pitch shifters, not addressing the critical formant control component of the
human
voice. They change formants when they alter pitch, so the voice that is pitched higher sounds like "Mickey Mouse".
There are some voice changers with a transformer's pitch slider where
you can control
pitch independently, without making formants change, while the formant slider works to effectively control the vocal
cords and shape of the vocal tract. So it can change a male voice into a female or even a child's voice, yet sound
completely natural.
This would be the ideal choice - although they are more expensive !

Pretender voice changers
Need a reason to hang up the phone? This pretender is your way out of difficult situations.
These type of voice changers offer several different sounds to get you off the hook fast such as :
When a collection agency calls, the baby cries out in the background;
or
If a stranger is on the other end, make a dog bark or the doorbell ring so it does not seem like you are at home alone;
or
When you are too busy to talk press the call waiting sound
These effects can be used individually, or in any combination, to make sure that you are not kept on the phone. In
addition to these sounds, the Pretender is equipped with six different settings to distort your voice, helping to
make it unrecognizable.
