20th December 2004
Cantor v1.5 is a major upgrade incorporating a completely revised vocal synthesis engine. The new engine makes it much easier to produce intelligible vocal lines. This was achieved with an improved filter model and a new kind of rule based phoneme sequencer which adapts the phoneme transitions according to the context inside a word.
New demo versions are also available. You can download the new demo versions directly from here:
