Short description: Hardware device or software which changes the pitch or timbre of the user's voice

A voice changer (also known as voice enhancer) is a device which changes the tone or pitch of or adds distortion to the user's voice, or a combination and vary greatly in price and sophistication.

Hardware implementations

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]

Software implementations

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]
