Voice Conversion Based on the HNT Model of Speech and Separate VQ Learning

In this paper, a text-dependent voice conversion method based on the mapping codebook approach is proposed. One of the critical tasks in voice conversion framework is speaker parameter estimation. In the given report the method based on the Harmonic-Noise-Transient (HNT) decomposition of speech is offered with an idea to separately process each of the components and further to separately convert them. Informal listening tests have shown the superiority of the presented system over the ACELP-based system.
