Voice Transformation

Diploma Thesis (pdf. 4.078KB)

In this diploma thesis algorithms for transformation of the human voice are developed. The following transformations are considered: changing the voice gender from male to female and conversely, artificial aging and rejuvenation of any voice and modification of the vocal effort. Based on the scientific literature, the essential characteristics of the transformations are identified. As opposed to "`Voice Conversion"' there is no target voice, the transformed voice has to sound like. The algorithms work mainly in the time domain and are based on the TD- PSOLA method. The implementation is done in Matlab and PRAAT. To evaluate the developed algorithms a listening test is conducted.
