Abstract

This project is the DSP implementation of innovative algorithms for voice transformation in real time. Voice transformation is the process of transforming the characteristics of speech uttered by a source speaker, such that a listener would believe the speech was uttered by a target speaker. In this project, two aspects of the transformation problem are addressed: voice quality and intonation. The main steps of the complete project include: a method for high quality voice transformation and designing a suitable algorithm in Matlab/Simulink. Voice transformation technology has been used more and more widely in many fields. Yet, the source voice patterns after transformation may exhibit a substantial degree of variance from the target speaker. The objective of this project was to develop a digital voice transformation program utilizing Matlab will be able to transform the voice from target speaker to source speaker. Matlab provided us with the necessary tools to record, filter, and analyze different voice samples and compare them to the archived sample. Research about the related will be done before design the program in Matlab. Troubleshooting will be done if there is any error occurs. At the end of this project, a complete project includes a method for high quality voice transformation will be implemented and a suitable algorithm in Matlab/Simulink will be designed.
