Voice changer

The term voice changer (also known as voice enhancer) refers to a device which can change the tone or pitch of or add distortion to the user's voice, or a combination and vary greatly in price and sophistication. A kazoo or a didgeridoo can be used as a makeshift voice changer, though it can be difficult to understand what the person is trying to say.^{[citation needed]}

The earliest voice changers were electronic devices usually used over the telephone for the purpose of disguise. There are low-priced, small lithium battery-powered voice changers that are used between a phone's mouthpiece and the user's mouth.^{[1][2][3][4][5]}

More sophisticated voice changers have different levels of various distortion effects variable by faders.^[6][7]

Nowadays, software implementations are very common. There is a plethora of techniques that modify the voice by using different algorithms.^[8][9] Most algorithms modify the voice by changing the amplitude, pitch and tone of the voice. The pitch plays an important role from changing a male voice into female voice, and vice versa. The results of voice changing through software are quite impressive and satisfactory.^[10]

"Voice cloning" software can mimic the sound of a specific person's voice based on recordings of that voice.^[11]
