Realivox

Realivox is a voice synthesizer.
About.
The software allows for delicate editing and adjustment of sounds. The software comes in two forms, although both aim to achieve similar goals. It is also able to work with Kontakt.
Reception.
Richard Leiter, at Keyboard magazine, commented that both products give an uncanny realistic result that had a "effortless" learning curve. He, however, commented that singers like Adele need not worry about the package's results. He felt the product was best suited for solo lines and backup singers, offering a product at the price that would cost more to do the same effort with real singers for a single vocal recording session.
