Voice conversion

Abstract

Voice Conversion is a process where new voices can be generated from an existing

voice, or even used to mimic a voice based on a database of sample voices. In this

Final Year Project (FYP), we will look at the mechanism of voice conversion,

focusing on the Vocal Tract Length Normalization (VTLN) technique.Using the voice conversion MATLAB toolbox STRAIGHT, this project will explore

the relationship between voices and set up transformation mechanisms using various

VTLN warping functions to generate different voices from an existing voice.

The functions will then be utilized together with MATLAB routines in a Graphical

User Interface(GUI) to enable user to step through the program runtime execution

with ease. The demo program will make use of the mechanism for traditional voice

conversion as well as certain special effects to demonstrate the application of the

technique.
