- Voice changer
The term voice changer refers to a system of altering a person's voice to either make them sound like someone else or to disguise their voice.
Voice changers change the tone or pitch, add distortion to the user's voice, or a combination of all of the above 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, smalllithium battery -powered voice changers that are used between a phone's mouthpiece and the user's mouth. More sophisticated voice changers have different levels of various distortion effects variable by faders.Software Implementations
Run a search online for a voice changer, and the vast majority of search results will be for software to do the task. The available programs are capable of altering the pitch and timbre of the user's voice, applying special effects, and performing graphic equalisation almost in real-time.
Unfortunately, at present, little is known about how such programs actually work, due to the fact that all examples found so far are either closed-source freeware or commercial software.
