Voice morphing

Voice conversion is a process of transforming the parameters of a source voice to those of a target voice. It is the process of compressing or stretching the time basis of the speech signal without changing its spectral contents. The second is to change the tone of the speech signal, called pitch scaling. It modifies the spectrum of the signal without changing its playback time. These two speech transformation functions are important in many applications such as speech transmission and storage, audio-visual systems, speech recognition, and text to speech conversion. speech modification is done by using pitch scale modification, spectrum modification. Different parameters can be modified like pitch level, pitch range, pitch contour, pitch variation using pitch scale modification. The aim for speech morphing is to produce a smooth change in speech identity
