This document describes the process of voice morphing, which involves transitioning one speech signal into another while preserving shared characteristics. It discusses representing speech signals in a domain that separates pitch and envelope information. A key step is dynamic time warping to match pitch features between signals. The morphed signal is created through interpolation and reconverted to an acoustic waveform. Examples show morphing between different gender pairs of speakers. Voice morphing aims to smoothly transition one voice into another in a similar manner as image morphing blends two faces.
