Abstract

Voice Transformation is simply transformation or modification of voice from sound of one speaker into another specified speaker. This modifies the perceptual quality of the voice. During transformation quality as well as similarity of the voice is to be maintained which determines the efficiency of the transformation process. Transformation made is generally in the features like spectral mapping, frequency, amplitude etc. Key idea for transformation is the mapping of acoustical features. Many models such as GMM and RBF are developed to establish the mapping and obtain a transformation system. This paper describes many other methods on the basis of survey done. Mapping plays a key role in attaining transformation of the voice and quality is the challenge faced currently and it’s the main point to be improved here.
