Voice morphing is a technique that modifies a source speaker's speech to sound like a target speaker. It does this by changing the pitch from the source speaker, like a male voice, to the target speaker, like a female voice. This is done by interpolating the linear predictive coding coefficients of the source and target signals. The pitch of the morphed signal can be positioned between the source and target by varying a constant value between 0 and 1. Applications include changing voices for security or entertainment purposes, but limitations include difficulties with voice detection and requiring extensive sound libraries.
