Introducing Synthesizer V, the Revolutionary Singing Synthesizer We aim to create a tool that ultimately leads to the artistic perfection of artificial voices, and the passion has been put into a 7-year quest for the scientific modeling of singing voice at the highest calibre. Synthesizer V, coming straight from the laboratory, is the outcome at the fifth iteration of this research project. Based on a hybrid of artificial neural networks and concatenative synthesis, Synthesizer V delivers natural voice from a small amount of sampled data. Our patent-pending Low Level Speech Model (LLSM) separately processes vocal folds and vocal tract features, thereby allowing for high-fidelity and flexible manipulation of voice timbre.
