Is the voice modeling section in the VoiceOne the same as in the newer VoiceWorksPlus?
VoiceWorksPlus features our latest generation modeling technology. There have been improvements to the modelling algorithms since VoiceOne but you will find both quite useful for modelling.
VoiceOne has more individual parameter access where VoiceWorksPlus has parameters grouped for easier editing. It really boils down to whether you want harmony contained in the same product or not.
