WHAT IS VOICE MORPHING ?
Voice Morphing which is also referred to as voice transformation and voice conversion is a technique to modify a source speaker's speech utterance to sound as if it was spoken by a target speaker.
There are many applications which may benefit from this sort of technology. For example, a TTS system with voice morphing technology integrated can produce many different voices. In cases where the speaker identity plays a key role, such as dubbing movies and TV-shows, the availability of high quality voice morphing technology will be very valuable allowing the appropriate voice to be generated (maybe in different languages) without the original actors being present.
APPROACHS TO THE PROBLEM
Voice conversion will be performed in two phases.
In the first phase, the training, the speech signals of the source and target speakers will be analyzed and the voice characteristics will be extracted by means of a mathematical optimization technique, very popular in the speech processing world, the Linear Prediction Coding (LPC) technique.
Conversion of voice
Wavelets are a class of functions that possess compact support and form a basis for all finite energy signals.
They are able to capture the non-stationary spectral characteristics of a signal by decomposing it over a set of atoms which are localized in both time and frequency. The DWT uses the set of dyadic scales and translates of the mother wavelet to form an orthonormal basis for signal analysis.
